Reverse Shoulder System

SURGICAL TECHNIQUE

Described by Charles Neer in 1983,1 the shoulder pathology known as Cuff Tear Arthropathy (CTA) has historically
been seen as a significant surgical challenge.
Non-constrained total or hemi shoulder arthroplasties have limited clinical outcomes in such indications, and most of
the constrained and semi-constrained prostheses developed in the 1970’s-1980’s for CTA (in particular, all reversed
ball and socket designs) remained purely experimental due to poor motion capability, instability and a high rate of
glenoid loosening.2,3,4
In 1985, Paul Grammont (Dijon University Hospital – France) designed the first semi-constrained reverse concept that
met the challenges inherent in cuff tear arthropathy cases.5 Known today as the DePuy Synthes Joint Reconstruction’s
DELTA CTA® Shoulder System, this Shoulder Prosthesis is a leading treatment for shoulder cuff tear arthropathy,6 with
more than twenty years of clinical success and 20,000 cases performed all over the world.
Based on the experience of the DELTA CTA® System, the next generation of reverse shoulder arthroplasty, the
DePuy Synthes Joint Reconstruction’s DELTA XTEND™ Shoulder Prosthesis has been designed using scientific,
engineering, and clinical knowledge in CTA cases in order to extend the clinical success associated with the 20 year
history of the DELTA CTA System.
Keeping the three design features that differentiated the DELTA CTA System from previous reverse designs
and made it successful:
•

•
•

Joint center of rotation positioned on the glenoid bone surface to avoid
pull-out torques on the glenoid component 7
Non-anatomic neck-shaft angle (155 degrees) for joint stability 3,5
Optimal deltoid tensioning to maximize its action without over-stretching the tissues7

Reducing the risk of scapular neck erosion and maximizing the shoulder range of motion: 8,9
• Inferior overlap of the glenoid component allowed by a new eccentric glenosphere design
and a new metaglene fixation system
Preserving bone to permit intervention and faster recovery with:
• Curved-back metaglene design9
• Reduced proximal geometry monobloc humeral stem for cemented application
• Cementless modular stem with eccentric epiphysis option
Design based on the success of the DELTA CTA Reverse Shoulder means that the DELTA XTEND System is the next
step forward for management of patients with Cuff Tear Arthropathy. The DELTA XTEND System allows you to treat
more patients, effectively.

PRE-OPERATIVE TEMPLATING AND PATIENT POSITIONING
Pre-operative Templating

Surgical Approach

An initial assessment of the glenoid bone should be
carried out using radiographic and CT imaging to
determine whether the patient is suitable for treatment.
The size of the glenoid vault should be assessed inferiorly
in particular to ensure that all four metaglene screws can
be placed within glenoid bone.

The DELTA XTEND Prosthesis can be implanted using
a superior-lateral deltoid split approach or a deltopectoral approach.

Pre-operative planning
should also be carried
out using AP and lateral
shoulder radiographs of
known magnification
and the available
template to help the
surgeon determine the
size and alignment of
the implant (Figure 1).
The final decision
should be made
intraoperatively.

The superior-lateral approach enables clear visualization
of the glenoid and therefore facilitates the implantation
of the glenoid components.
The delto-pectoral approach has the advantage of
offering a good view of the inferior part of the glenoid.
Therefore, the choice mainly depends on the surgeon’s
preference and clinical parameters.

Figure 1

Patient Positioning
The patient should be in the beach chair position, with
the affected arm completely free and on a support
(Figure 2).

Revision surgery, for instance, is usually performed using
a delto-pectoral approach since the patient has already
had that incision and since it allows for a longer humeral
incision when faced with difficult removal of the humeral
stem. However, for cases of retroverted glenoid, the
implant placement can be more difficult via the deltopectoral approach and can lead to damage of the deltoid
muscle. Moreover, as the rotator cuff lesion is mainly
located at the supero-posterior aspect of the cuff, the
(partial) insertion of the remaining subscapularis (that
is often needed through this approach) could weaken
the remaining muscular structure. The superior-lateral
approach may be preferred in these cases.

Figure 2

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

SURGICAL TECHNIQUE
Superior-lateral Approach
The skin incision is 10-12cm long and can be
antero-posterior along the lateral edge of
the acromion or made in a lateral direction
(Figure 3). Following subcutaneous dissection,
separate the anterior and middle deltoid
muscle bundles opposite the lateral margin of
the acromion using blunt dissection (Figure 4).
The dissection starts at the level of the AC
joint, 5-7mm posterior to the tip of the
acromion, and extends straight laterally down
into the deltoid muscle. It should not extend
more than 4cm from the external aspect of
the acromion in order to preserve the axillary
nerve which is located at the turning fold of
the subacromial bursa.
Figure 3

When the subacromial bursa is visible,
gentle longitudinal traction in line with the
limb allows a retractor to be placed in the
subacromial space. The anterior deltoid is
then released subperiosteally from its acromial
insertion up to the AC joint. The deltoid
release from the anterior acromion can include
a small piece of bone to facilitate repair and to
protect the deltoid muscle.
Once the subacromial bursa has been
removed, the humeral head is visible at the
anterior edge of the acromion. Exposure may
be improved, if necessary, by dividing the AC
ligament and performing acromioplasty.

Figure 4

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

The limb is then externally rotated and the
head is dislocated antero-superiorly to facilitate
positioning of the cutting guide. If the bicep
tendon is still present, a tenotomy or tenodesis
should be performed. The subscapularis,
teres minor and infraspinatus are retained
when present. A partial detachment of the
subscapularis may be performed when the
superior dislocation of the humerus is difficult
to obtain.

Delto-pectoral Approach
The skin incision follows the line from the
midpoint of the clavicle to the midpoint of
the arm (Figure 5). Subcutaneous flaps are
elevated to expose the fatty strip that marks
the delto-pectoral interval. Dissect medial
to the cephalic vein and retract it laterally
with the deltoid muscle (Figure 6). Incise the
clavipectoral fascia from the inferior border
of the coracoacromial ligament distally to the
superior border of the tendon of the sternal
head of the pectoralis major (Figure 7). Sharply
and bluntly dissect the humeroscapular
motion interface (subacromial, subdeltoid and
subcoracoid). Palpate the axillary nerve at the
anterior-inferior border of the subscapularis
muscle. Electrocoagulate or ligate the anterior
humeral circumflex vessels near the humerus
at the inferior border of the subscapularis
(Figure 8).
If the bicep’s long head tendon is intact, open
its sheath and tenodese the tendon in the
groove or to the pectoralis major tendon with
non-absorbable sutures. Excise the proximal
biceps tendon and hypertrophic sheath. A
biceps tenotomy can also be performed in
elderly patients.
Place a tag suture in the tendon of the
subscapularis, 2cm medial to its point of
insertion, in the lesser tuberosity. Release the
tendon, along with the underlying capsule,
from the lesser tuberosity and the proximal
humerus (Figure 9). Strip the remaining
inferior and posterior-inferior capsule from
the humerus. Dislocate the humeral head
(Figure 10).

INTRAMEDULLARY CANAL PREPARATION

Proximal Entry Point

Using the 6mm medullary canal reamer, make
a pilot hole in the cortical surface of the bone
eccentrically and as superior as possible so
that the reamer passes directly down the
intramedullary canal (Figure 11). Ream the
medullary canal using the T-Handle on the
reamer. Do not use a power tool as this could
remove more bone than necessary.
When using the standard length prosthesis,
pass the reamer down the intramedullary
canal until the projecting circular mark on
the reamer is level with the pilot hole. When
using the long stem prosthesis, pass the
entire length of the cutting flutes down the
intramedullary canal.

Figure 11

Continue to ream sequentially until the
reamer begins to bite on the cortical bone
of the intramedullary canal of the humerus
(Figure 12).
The final reamer size will determine the size
of the cutting guide handle, the epiphyseal
reaming guide, the broach, trial stem and final
implant. For example, if the 12mm reamer
begins to gain purchase in the intramedullary
cortical bone, use a 12mm humeral trial stem
and final component.

Select the handle for the cutting guide of the
appropriate size. Taking the previous example,
if reaming stopped at 12mm, select the 12mm
handle. Select the cutting guide and cutting

Drive the cutting assembly down the
intramedullary canal until it is fully in contact
with the top of the humeral head. The
orientation pin is then passed through the
hole in the cutting handle in the desired
retroversion. The retroversion is calculated
with reference to the forearm axis. This
should preferably be close to 0 to 10 degrees
since excessive retroversion can restrict joint
rotation, especially internal rotation. The
cutting handle should then be turned to align
the orientation pin and the forearm (Figure 14).

Slide the cutting plate to adjust the resection
level. The cutting plate color code shows if the
resection level is appropriate. If the cutting
level indicator is green, the guide is at the
correct height. If it is red, the cutting plate
needs to be adjusted (Figure 15).

Visually verify that the resection is 1 to 2mm
below the proximal area of the greater
tuberosity (at the level of the supraspinatus
insertion in an intact shoulder).
Note that the angle of the cut is 155 degrees
and therefore different from the anatomical
neck/shaft angle (135 degrees). This angle
gives optimal joint stability to the reverse
prosthesis.6
Pre-drill the cortical bone through the cutting
plate using a 3.2mm drill bit, and insert the
two fixation pins to fix the cutting plate to the
humerus (Figure 16).

Remove the cutting guide and add a third
fixation pin through the cutting plate to secure
the assembly and resect the humeral head,
aligning the saw blade with the superior aspect
of the cutting plate (Figure 17, Step 1).
Note: The two external pins are parallel. The
cutting plate can therefore be turned upside
down before securing it with the third pin
to obtain a flat surface (Figure 17, Step 2).
Place a protecting plate on the humeral
resection surface to protect the bone from
damage during the following surgical steps
(Figure 18).
Pass a forked retractor under the scapula to
lower the humerus. If this provides a clear
view of the glenoid surface, the resection
level is correct. If not, a further humeral head
resection may be performed.

EXPOSING THE GLENOID
Position a forked retractor in the axillary
margin of the scapula under the inferior
glenoid labrum to move the humerus down or
backward, depending on the approach taken
(Figure 19).
When exposing the glenoid, it is critical to note
the presence of the axillary nerve and protect
it at all times. Excise the biceps remnant and
entire labrum. Release the entire capsule
from around the glenoid. In certain cases, the
capsule may have to be excised depending
on the extent of any contractures and the
adequacy of exposure. In some cases, the
origin of the triceps long head may be incised
from the infraglenoid tubercle.

Figure 19

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

Bluntly (finger or elevator) dissect in a
circumferential manner from the base of the
coracoid process to well beyond the most
inferior aspect of the glenoid. It is essential
to palpate the following osseous scapular
orientation points: the base of the coracoid
process, the inferior part of the glenoid neck
and, when possible, infra glenoid tubercle and
lateral border of the scapula. Retractors should
be placed so that the entire glenoid face is in
clear view to aid accurate placement of the
guide pin.

Subscapularis Mobilization in
the Delto-pectoral Approach
Both sharp and blunt methods are used
to mobilize the subscapularis. Completely
release the rotator interval to the base of the
coracoid process and release the superior
border of the subscapularis from the base of
the coracoid process. Then completely release
the motion interface between the coracoid
muscles (conjoined tendon) and the anterior
subscapularis. Lastly, completely release the
posterior border of the subscapularis tendon
and distal muscle belly from the anterior and
anterior-inferior glenoid rim, glenoid neck and
the most lateral part of the scapular body.
Figure 20

Glenoid Preparation
Remove any remnants of labrum from the
glenoid. Then remove all articular cartilage
(large straight curette) from the glenoid face.
In addition, any osteophytes present may
also have to be removed to determine the
bony anatomy (Figure 20).

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

POSITIONING THE METAGLENE CENTRAL PEG
Positioning of the metaglene is important to
achieve an optimal glenoid fixation, to limit
potential bone impingement and to achieve a
final good, stable range of motion. Therefore,
particular attention should be given to that
surgical step.
The position chosen should maximize contact
with the glenoid bone surface and to allow
secure fixation of the screws in bone.
The metaglene should ideally be positioned
on the lower circular area of the glenoid bone.
The metaglene central peg is positioned in
the center of the inferior circle of the glenoid
(This point is often posterior and inferior to the
intersection of the glenoid axis) (Figure 21).

Figure 21

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

These anatomical reference points help to
position the metaglene as inferior as possible
on the glenoid bone in order to limit potential
bone impingement, while keeping a secure
glenoid implant fixation. However, radiographic,
CT images combined with X-ray templates
and pre-operative view can lead to a choice
of position a little bit more superior to obtain
fixation in good bone stock and complete
seating of the metaglene on the bone.

The metaglene positioner is used to obtain the
optimal metaglene position. The positioner
plate is the same diameter as the metaglene.
Assemble the positioner by inserting and
threading the internal rod into the positioner
handle (Figure 22).
Insert the hex head tip of the handle in
the corresponding plate hole (right or left
depending on the shoulder being operated
upon) and lock the assembly by tightening the
internal rod (Figure 23).
Note: The handle is set at an angle
of 20 degrees to the plate to ensure
optimal visibility (Figure 24).

Figure 22

20°

Figure 23

Figure 24

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

Position the plate as low as possible so that its
border follows the inferior edge of the glenoid.
Note that inferior osteophytes may result in
malpositioning. X-rays should therefore be
checked to avoid this problem.

Figure 25

Providing that the morphology of the glenoid
hasn’t been altered by the disease, the guide
plate is perpendicular to the plane of the
glenoid face. Make sure that the proximal
handle of the instrument is not tilted
superiorly. The guide pin should be inserted
either perpendicularly to the glenoid face
or with the distal tip of the guide pin in a
slightly superior direction. This ensures that
the glenosphere will either be perpendicular
to the plane of the glenoid face or have a
slight inferior tilt which may reduce the risk of
scapular notching.
Place the 2.5mm metaglene central guide pin
in the plate is central hole and drill it through
the far cortex using a power tool (Figure 25).
Remove the metaglene positioner, leaving the
guide pin in place (Figure 26).
Note: The 2.5mm Breakaway Guide Pin (223000-019) may be used as a substitute for the
Metaglene Central Guide Pin (2307-87-004).
The grooves on the 2.5mm Breakaway Guide
Pin are exclusively used for the breakaway
feature and are not intended to indicate the
depth to which the pin should be inserted.
The pin is designed to break at the grooves.
Be aware that it may break unintentionally
if subjected to too much bending force.
After use of the guide pin is complete, confirm
that all sections (totaling the full length of the
original, unbroken pin) have been removed.

Figure 26

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

REAMING THE GLENOID BONE
Slide the 27mm glenoid resurfacing reamer
onto the central guide pin and ream either
manually or using a power tool. This reamer
prepares a smooth curved surface with the
same diameter as the metaglene (Figure 27).
Use the metaglene reamer carefully to avoid
any inadvertent fracturing of the glenoid,
especially if the glenoid is sclerotic. Make
sure the axillary nerve is protected. Initiate
and proceed with the reaming, turning at
low speed prior to engaging the glenoid.
It is useful to collect the osseous products
of reaming and irrigate often to maximize
visualization and thereby ensure optimal
reaming. Be careful not to over ream and to
preserve the subchondral bone.
Ream the superior glenoid bone by hand,
using the manual 42mm glenoid reamer
(Figure 28). This step is necessary to avoid any
potential conflict between the glenosphere
and the superior area of the glenoid bone
(Figure 29).

Figure 27

Manual reaming should be carried out until
the central part of the manual reamer is in full
contact with the curved central glenoid surface.

Figure 28

Figure 29
Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

Use the manual glenoid reamer to ream the
glenoid anteriorly, posteriorly and inferiorly
if necessary. A smooth surface without any
remaining cartilage should be obtained.
Check the adequacy of the reaming by
applying the glenoid reaming level checker on
the glenoid surface. No space (except if due
to bone erosion) should be seen between the
instrument and the glenoid surface (Figure 30).
Remove the resurfacing reamer, leaving the
metaglene central guide pin in place
(Figure 31).
Figure 30

Refering to the chart below, connect the
appropriate size cannulated stop drill to the
power source and drill the central hole over
the guide pin until full contact between the
drill and bone is obtained (Figure 32).
Remove the stop drill and the central guide pin.
Note: After use of the guide pin is
complete, confirm that all sections
(totaling the full length of the original,
unbroken pin) have been removed.

METAGLENE IMPLANTATION
Assemble the internal rod of the metaglene
holder in the metaglene holder main body.
Insert the metaglene holder hex tip in the
desired final metaglene implant central hole
and tighten the assembly. (Figure 33).
Place the metaglene on the glenoid bone
and ensure that the metaglene is fully
seated. Apply bone graft if necessary to
help fill surface irregularities between the
metaglene and the glenoid bone. Rotate the
metaglene so that the inferior screw can be
aimed toward the scapular neck. The vertical
metaglene marking should be aligned with
the scapular neck inferiorly and with the
base of the coracoid process superiorly (long
axis of the glenoid bone) (Figure 34). The
metaglene peg is 0.6mm larger in diameter
than the drill to enable a press fit. Gently
impact with a mallet in the proper orientation
for inferior screw placement and then remove
the metaglene holder.

INFERIOR AND SUPERIOR METAGLENE
SCREW PLACEMENT
Locking metaglene screws allow an angulation
of ± 10 degrees around the optimal 17
degrees screw positioning recommended by
Professor Grammont (Figure 35).
Place the 2.5mm drill guide in the metaglene
inferior hole. The drill guide can be angled
to ± 10 degrees but should always be seated
fully in the metaglene hole. Palpate the
scapular neck and aim into good bone. Using
the 2.5mm drill bit, start drilling through
the subchondral bone to aproximately 10 to
12mm deep (Figure 36). Then stop drilling and
push gently on the drill bit to make sure that
the drill is contained in the bone. Redirect and
redrill if uncontained. When a satisfactory
drilling direction has been obtained, drill and
push until the cortex is perforated.

The goal is to have a sufficiently long screw
inferiorly, usually 36mm or more. The length
of the screw is indicated on the drill bit by
laser markings (Figure 37). The screw depth
gauge can also be used to assess optimal
screw length.

Figure 37

Insert the 1.2mm guide pin through the
drill guide and then remove the drill guide

Slide the locking screwdriver body on the
guide pin and insert the tip into the four slots
on the screw (Figure 40). Do not use the
internal screwdriver rod at this stage.
Note: Slide down the screwdriver sleeve
completely to protect the screw head.
Tighten the screw to compress the plate
(Figure 41a).
Figure 40

Remove the screw guide pin with the pin
extractor before final tightening to avoid
stripping, making sure that the internal locking
screw stays in place.
Repeat the same steps for the superior
locking screw.
Note: Use care to ensure that the
driver remains in axial alignment
with the screw so that the driver tip
remains fully engaged (Figure 41b).

Figure 41a

Note: The tip of the screwdriver can
lose contact with the fins and does not
torque evenly on all sides if the protecting
sleeve is not used (Figure 41c).
Note: The protecting sleeve is not designed
to lock onto the screw. It must be held
in place with a finger during insertion.

Drill the hole for the superior locking screw
anticipating exit through the far cortex using
the same methods as Figure 36 (inferior
screw placement) (Figure 42). The superior
screw should be directed at the base of the
coracoid process and should have an anterior
orientation to avoid the suprascapular nerve.
To obtain optimal compression of the
metaglene plate on bone, alternate tightening
of the superior and inferior locking screws
(Figure 43).
Note: Use care to ensure that the driver
remains in axial alignment with the screw so
that the driver tip remains fully engaged.

The surgeon may use locking or non-locking
screws in the anterior or posterior holes. Both
types of screws will allow an angulation of
up to ± 10 degrees, but not in a direction
convergent to the central peg axis to avoid
conflict with the central peg (Figure 44).
Use the 2.5mm drill bit with the drill guide to
set the most appropriate angle for ensuring
that each screw is located in reliable bone
stock (Figure 45).
The preferred position is usually chosen by
palpating the anterior and posterior aspects
of the scapula as well as examining the X-rays
and CT scans. Drill in the direction of the
central glenoid vault in an attempt to maximize
the anterior and posterior compression screw
lengths, in a direction parallel to or divergent
from the central peg.

slide the reaming guide into the reamer holder
and fasten the two parts together by firmly
tightening the upper round handle (Figure 50).
Push the holder horseshoe plate fully down
(Figure 51).
Slide the proximal reaming guide down

FOR CEMENTLESS MODULAR IMPLANTS

The cementless modular implant is designed
to allow the surgeon to place the epiphysis in
anatomic version and the stem in anatomic
version for an optimal press-fit.
The size and type (centered or eccentric) of
modular epiphysis should be chosen to ensure
that the best possible coverage of the bone
resection surface is achieved.
First select the centered proximal modular
reamer adaptor, and place it on the reaming
guide’s angled pin.

Centered Adaptor
Size 1 & 2
Disk Size 1

Choose the most appropriate epiphysis size
using the modular implant sizer disks, size 1
or 2. The sizer disk chosen should provide the
best coverage of the bone resection surface
without overhang (Figure 55).

Disk Size 2
Figure 55

If this does not provide a good fit with the
bone resection surface, switch the centered
proximal modular reamer adaptor for the
eccentric adaptor in size 1. Be careful to
position the eccentricity so that it is posterior
and not anterior, double checking with the
markings (anterior and posterior) on the
adaptor.
Then check the epiphysis size again with sizer
disk 1. If the bone coverage is not sufficient,
use eccentric adaptor size 2 and sizer disk size 2
(Figure 56).
Remember the final decision made, with
respect to the centered or eccentric epiphysis
and size 1 or 2, will determine reamer and final
implant sizes.

to the broach handle. Make sure that the
goniometer is in place on the broach handle.
Drive the broach into place, carefully checking
that its anterior fin is aligned with the anterior
aspect of the bicipital groove. This will ensure
good distal stem orientation (anatomic version)
for an optimized press-fit (Figure 59).

Drive the broach down carefully, (to avoid any
cortical bone damage) until the rocking bar of
the broach handle is in full contact with bone,

FOR CEMENTLESS MODULAR IMPLANTS

The trial modular epiphysis (centered or
eccentric, size 1 or 2, depending on the
proximal reaming choices made) is placed on
the trial modular stem (diameter chosen during
distal reaming and broaching).
The epiphysis position corresponds to the
adjustment angle previously read on the
broach handle goniometer. For example, if 20
degrees right was read on the goniometer, the
epiphysis hole marked 20 degrees right should
be positioned in line with the stem orientation
peg (Figure 61).

Figure 61

Note: This angulation corresponds to the
difference between the version of the stem
(close to anatomical retroversion – 20 to 30
degrees) and the epiphysis version for a reverse
shoulder (close to 0 degrees retroversion).
No calculation is required: the
instrumentation has been designed to
provide direct measurement of this position
on the goniometer.
The two components are then screwed
together using the 3.5mm hex screwdriver
and the special locking wrench for modular
implants (Figure 62).
Both components are then mounted on the

GLENOSPHERE TRIAL PLACEMENT
The glenosphere implants are available in
two diameters, 38 and 42mm, and are either
standard or eccentric spheres.
An overlap of 3 to 5mm is recommended to
avoid conflict with the scapular neck (Figure 70).
Depending on the shape of the scapular neck,
this overlap can be achieved by using a standard
metaglene just by lowering the metaglene.
The 42mm glenosphere is recommended if
the size of the joint allows (increases both the
overlap and the range of motion). The eccentric
glenospheres are recommended for more
transverse scapular necks.

Figure 70

Fit the appropriate trial glenosphere (38mm
or 42mm, centered or eccentric) to the the
metaglene using the metaglene holder
(Figure 71). The trial glenosphere utilizes an
interference fit to make the connection with
the metaglene.
For eccentric glenospheres, the vertical
laser mark on the trial glenosphere should
be aligned with the base of the coracoid
superiorly and the scapular neck inferiorly
(Figures 71 and 72).
The arrow indicates the position of the
eccentricity and should be positioned inferiorly,
aligned with the scapular neck (Figures 72).
Note: If it is difficult to place the glenosphere
trial, then check to ensure the superior portion
of the glenoid has been reamed adequately
and that there is no soft tissue in the way.

CUP TRIALS AND TRIAL REDUCTION
Place the humeral trial cup (38 or 42mm
depending on the glenosphere size), with
+3mm of lateral offset, in the trial epiphysis
(Figure 73). The shoulder should then be
reduced with longitudinal traction and
assessed for a full range of motion (Figure 74).

Figure 73

Figure 74

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

JOINT TENSIONING AND STABILITY ASSESSMENT
Joint tensioning and stability assessment
should be performed with particular care,
using the following guidelines:
• Tension within the conjoined tendon should
be noticeably increased and detectable by
palpation.
• With the arm in a neutral position, apply
a longitudinal traction force to the arm
while observing the movement of the
shoulder with respect to the entire shoulder
girdle as well as the trial prosthetic joint.
Tension is appropriate if, in response to the
longitudinal traction, the entire shoulder
moves before detectable separation of the
trial prosthetic surfaces.
• External rotation may appropriately
demonstrate slight gapping between
the glenosphere and articular surface
(2 to 3mm maximum).
• Positioning a hand or fist near the axilla
to serve as a fulcrum, further adduct the
arm and look for undesirable tendencies to
sublux or dislocate laterally (a small opening
of 2 to 3mm is acceptable). Estimate the
maximum forward elevation.10
• Assess stability at 90 degrees, abduction
with the humerus in neutral, maximum
internal and maximum external rotation.
Estimate the maximum forward elevation.10
If instability can be demonstrated, it is critical
to identify the cause and develop a solution
to the problem. Make sure that the implants
have been positioned correctly with respect
to the bone and to each other. Overcome
any conflicts between the proximal humeral
component and soft tissues or osseous

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

structures that surround the glenosphere
(e.g. non-union of the greater tuberosity)
by excision of the conflicting elements.
Inadequate tensioning may be overcome using:
• A thicker cup (+6mm or +9mm)
• A 42mm glenosphere
• A modular humeral lengthener or retentive
cups in more extreme cases
If unable to reduce the joint, the options
include additional soft tissue releases and
lowering the level of humeral resection.
When the trials are satisfactory, the trial
glenosphere should be removed using the
extraction T-Handle so that final implant
fixation can be performed.

DEFINITIVE GLENOSPHERE FIXATION
Standard Glenosphere

Insert the 1.5mm guide pin through the
central hole of the metaglene.
Engage the 3.5mm cannulated hex screwdriver
in the final glenosphere. Slide the glenosphere
on the 1.5mm guide pin until it is in contact
with the metaglene (Figure 75). Proper
alignment between the glenosphere and
metaglene is absolutely essential to avoid cross
threading between the components.
If the glenosphere seems difficult to thread
onto the metaglene, do not force engagement
but re-align the components. If necessary,
remove the inferior retractor or improve the
capsular release. It is also important to check
that there is no soft tissue between the
metaglene and glenosphere.

Figure 75

When accurate thread engagement is obtained
and after a few turns, remove the guide pin to
avoid stripping in the screwdriver.

Standard glenosphere
Tighten until the scapula begins to rotate
slightly in a clockwise direction, meaning that
the glenoid bearing is closing on the taper of
the metaglene.
Gently tap on the glenosphere with the
glenosphere impactor a minimum of three times
(Figure 76). Tighten the glenosphere central
screw again. Care should be taken to ensure
that the glenoid bearing is fully locked onto the
metaglene. The gentle hammering procedure
and screw tightening can be repeated, if
necessary, until the screw is fully tightened.
Note: Glenosphere will sit about 1mm proud
on the metaglene with consistent uniformity

DEFINITIVE GLENOSPHERE FIXATION
Eccentric Glenosphere

Eccentric glenosphere
Slide the glenosphere orientation guide onto
the screwdriver core and position it in the
eccentric glenosphere central slot (Figure 77).
The arrow marked on the orientation guide
should be aligned with the base of the
coracoid process to position the eccentricity
correctly. Maintain the orientation guide in the
required position and screw the glenosphere
into place using the screwdriver until the
glenoid bearing closes on the taper of the
metaglene (Figure 78).

Figure 77

Obtain further impaction of the junction
by gently hammering the glenosphere with
the glenosphere impactor a minimum of

Once you are confident that you have
perfect aligment, impact the humeral
cup at a 90 degree angle to the epiphysis
(Figure 89). Make sure the arm is fully
supported to ensure full impaction.

Step 3
Once fully seated there will be approximately
a 1mm gap between the lip of the cup and
the epiphysis. The 1mm gap will aid future
revisions if necessary. The cup should not
move or shift when touched. If this is the
case, realign the implant and repeat the
impaction steps (Figure 90).

Figure 89

When a humeral spacer is needed, impact
it first on the epiphysis and then impact the
final cup on it.
Note: All junction surfaces between the
implant components should be clean and
free of any tissue before impaction.
Reduce the joint and carry out a final
assessment of joint stability and range

CASES OF PROXIMAL HUMERAL BONE LOSS
Cases of proximal bone loss will be treated
using cemented monobloc humeral implants
to avoid any risk of component dissociation.
Long monobloc stems may be required in
some cases.
The preparation of the humeral canal for long
stems uses the same technique described for
standard stems, with the exception of the
procedure for reaming the humeral canal,
which differs in this respect: the entire length
of the cutting flutes should be passed down
the intramedullary canal instead of being
stopped at the mark (Figure 91).
A positioning jig is available to hold both the
trial long stem and the final implant in place at
the correct height and in retroversion.

Tighten the fin clamp on the humeral
shaft first using the 3.5mm screwdriver
(Figure 92).

Place the fin clamp over the vertical
height gauge of the humeral shaft clamp
and secure the fin clamp to the central
hole in the anterior fin of the prosthesis.

Place the prosthesis at the
appropriate height.

POST-OPERATIVE MANAGEMENT

Post- operative physiotherapy is an important factor in the outcome of this procedure, since stability and mobility now
depend on the deltoid alone. The physiotherapy program, which should be planned to suit each individual patient, consists
of two phases:

1. Early phase (0 to 6 weeks)

2. Late phase (after 6 weeks)

Two days after the operation, the patient may be mobile.
This early phase is dedicated to gentle and gradual
recovery of the passive range of shoulder motion:
abduction of the scapula, anterior elevation and medial
and lateral rotation. An abduction cushion may be used
to relieve pressure on the deltoid. Physiotherapy is mainly
performed with the patient supine, passive and with
both hands holding a bar that is manipulated by the
contralateral hand, as described by Neer. The patient is
encouraged to use the affected arm post-operatively to
eat and write, but should not use it to push behind the
back or to raise themselves from the sitting position to
the standing position. In conjunction with these exercises
for scapulohumeral recovery, it is important to strengthen
muscle connection with the scapula in order to facilitate
muscle and implant function. Passive exercise in a
swimming pool is recommended as soon as scars begin
to form. More caution is required to protect the deltoid
muscle from excessive demand if a superior approach has
been used for surgery.

After the sixth week, active strengthening movements
may gradually be added to the program. These
exercises, which closely follow everyday activities, are
to be performed in a sitting or standing position using
conventional methods, with isometric exercises and
resistance movements becoming increasingly important.
A series of exercises for rhythmic stabilization of the
upper arm as well as eccentric work on lowering the arms
complete the strengthening of the muscles. Physiotherapy
may be performed over a period of at least six months.

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

ESSENTIAL PRODUCT INFORMATION
IMPORTANT: This Essential Product Information sheet does not include all of the information necessary for selection and use of the device.
Please see full labeling for all necessary information.

INDICATIONS FOR USE:
The DELTA XTEND Shoulder Prosthesis is indicated for use in treatment of a grossly deficient rotator cuff joint with:

•

severe arthropathy and/or;
a previously failed joint replacement and/or;
fracture-dislocations of the proximal humerus where the articular surface is severely comminuted, separated from its blood
supply or where the surgeon’s experience indicates that alternative methods of treatment are unsatisfactory

The patient’s joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use
the device.
DELTA XTEND hemi-shoulder replacement is also indicated for hemi-arthroplasty if the glenoid is fractured intraoperatively or for the revision of a
previously failed DELTA XTEND Reverse Shoulder.
The metaglene component is HA coated and is intended for cementless use with the addition of screws for fixation.
The modular humeral stem and humeral epiphysis components are HA coated and intended for cementless use.
All other metallic components are intended for cemented use only.

CONTRAINDICATIONS:
Joint replacements may be contraindicated where the patient is overweight, where there is infection, poor bone stock, severe deformity, drug abuse,
overactivity, tumor, mental incapacity, muscle, nerve or vascular disease.
Note: Diabetes, at present, has not been established as a contraindication. However, because of increased risk for complications such as infection, slow
wound healing, etc., the physician should carefully consider the advisability of shoulder replacement in the severely diabetic patient.

WARNINGS AND PRECAUTIONS:
CAUTION
• Implants and trial components from different manufacturers or implant systems should never be used together, with the exception of
GLOBAL UNITE Humeral Stems and DELTA CTA as described below.

−

When well-fixed, the GLOBAL UNITE Humeral Stems, in conjunction with existing DELTA XTEND epiphyseal components,
can be used when conversion to a reverse is necessary.
When well-fixed DELTA CTA stem, the DELTA XTEND glenosphere and metaglene can be used with DELTA CTA Hybrid
Humeral Cups, Humeral PE Cups dia 42mm and/or spacers described in the DELTA XTEND Surgical Technique.

• Shoulder prosthesis components should never be reimplanted. Even though the implant appears undamaged, the implant may have developed
microscopic imperfections, which could lead to failure. DePuy’s Single Use devices have not been designed to undergo or withstand any form of
alteration, such as disassembly, cleaning or re-sterilization, after a single patient use. Reuse can potentially compromise device performance and
patient safety.
• Always use a trial prosthesis for trial purposes. Trials should not be assembled with any components intended for permanent implantation. Trials
must have the same configuration size, etc., as the corresponding components to be implanted.
• Do not alter or modify implants in any way.
• The use of a glenoid prosthesis in patients with cuff tear arthropathy could increase the risk of glenoid component loosening due to non-anatomic
loading conditions.
• The DELTA XTEND Reverse Shoulder Prosthesis has not been evaluated for safety and compatibility in the MR environment. The DELTA XTEND
Reverse Shoulder Prosthesis has not been tested for heating or migration in the MR environment.

DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

INDICATIONS FOR USE:
A DELTA CTATM Reverse Shoulder Prosthesis is indicated for use in:

• Grossly rotator cuff deficient joint with severe arthropathy or a previous failed joint replacement with a grossly rotator cuff deficient joint.

• The patient’s joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is
necessary to use the device.

• The metaglene component is HA coated and is intended for cementless application with the addition of screws for fixation.
For US use only: All other components are intended for cemented use only.

CONTRAINDICATIONS
Joint replacements may be contraindicated where the patient is overweight, where there is infection, poor bone stock, severe deformity, drug abuse,
overactivity, tumour, mental incapacity, muscle, nerve or vascular disease.

WARNINGS AND PRECAUTIONS
CAUTION:
• Implants and trial components from different manufacturers or implant systems should never be used together. However, in case of a DELTA CTA
implant revision with a well-fixed DELTA CTA stem, the DELTA XTEND glenosphere and metaglene can be used with specific DELTA CTA Hybrid
Humeral PE cups described in the DELTA XTEND Surgical Technique, existing DELTA CTA Humeral PE cups diameter 42mm and /or DELTA CTA
Spacers.
• Shoulder prosthesis components should never be reimplanted. Even though the implant appears undamaged, the implant may have developed
microscopic imperfections, which could lead to failure.
• Always use a trial prosthesis for trial purposes. Trials should never be assembled with any components intended for permanent implantation.
Trials must have the same configuration size, etc., as the corresponding components to be implanted.
• Do not alter or modify implants in any way.
• The DELTA CTA Shoulder Prosthesis has not been evaluated for safety and compatibility in the MR environment. The DELTA CTA Shoulder
Prosthesis has not been tested for heating or migration in the MR.
