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 component7

• 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.

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

Pre-operative Templating

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.

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.

Patient Positioning

The patient should be in the beach chair position, with

the affected arm completely free and on a support

(Figure 2).

PRE-OPERATIVE TEMPLATING AND PATIENT POSITIONING

Figure 1

Figure 2

Surgical Approach

The DELTA XTEND Prosthesis can be implanted using

a superior-lateral deltoid split approach or a delto-

pectoral approach.

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.

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 delto-

pectoral 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.

98 DePuy Synthes Joint Reconstruction DELTA XTEND™ 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.

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.

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.

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

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).

Proximal Entry Point

INTRAMEDULLARY CANAL PREPARATION

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.

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

plate according to the surgical approach used

(superior-lateral or delto-pectoral).

Assemble the plate on the cutting guide

first (1) and then fix the cutting guide on the

cutting handle (2) (Figure13).

The cutting guide should be fully seated on

the cutting handle.

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).

Delto-pectoral ApproachSuperior-lateral Approach

Superior-lateral Cutting Plate Delto-pectoral Cutting Plate

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).

Delto-pectoral Approach Superior-lateral Approach

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.

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.

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).

1716 DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

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).

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.

POSITIONING THE METAGLENE CENTRAL PEG

Figure 21

17

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

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

Figure 24

Figure 23

20°

1918 DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

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.

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 (2230-

00-019) 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.

Surgical Technique DELTA XTEND™ DePuy Synthes Joint Reconstruction

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).

Manual reaming should be carried out until

the central part of the manual reamer is in full

contact with the curved central glenoid surface.

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).

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.

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.

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.

Insert the 1.2mm guide pin through the

drill guide and then remove the drill guide

(Figure38).

Slide the locking screw of the appropriate

length onto the guide pin. Check that the

internal tightening screw is unlocked (it should

rotate freely) (Figure 39).

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).

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).

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.

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.

Screw length is determined from the laser marks

on the drill bits or by using the depth gauge.

Slide the corresponding screws onto the guide

pin and tighten using the 3.5mm cannulated

hex screwdriver for non-locking screws or

the locking screwdriver for locking screws

(Figure46).

Follow the same procedure for the posterior

screw, then alternately tighten both screws

until they are fully tightened.

Proceed with locking all variable angle

screws used. Place the locking screwdriver

main body in the head of the inferior screw.

Make sure that the screwdriver sleeve is in its

upper position and not in contact with the

screw head.

Slide the locking screwdriver internal rod into

the main body. The tip of the internal rod will

make contact with the screw head. Tighten it

fully, locking the screw in place by expanding

its head (Figure 47).

Note: After inserting all four screws, tighten

the locking screws with the internal rod

for the locking screwdriver. Pull the sleeve

up and off the screw head for this step.

Repeat the same steps to secure the superior

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.

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).

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.

the trial modular stem (diameter chosen during

distal reaming and broaching).

The epiphysis position corresponds to the

adjustment angle previously read on the

degrees right was read on the goniometer, the

epiphysis hole marked 20 degrees right should

be positioned in line with the stem orientation

Note: This angulation corresponds to the

difference between the version of the stem

(close to anatomical retroversion – 20 to 30

GLENOSPHERE TRIAL PLACEMENT

Figure 70

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.

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

assessed for a full range of motion (Figure 74).

Figure 74

3938 DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

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

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.

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.

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.

Cases of proximal bone loss will be treated

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

• In case of a DELTA CTA System 36mm epiphysis,

use 38mm or 42mm hybrid cups consistent

with the glenoid diameter used. Hybrid cups

are available in three different heights (+3mm,

+6mm and +9mm)

• In case of a DELTA CTA 42mm epiphysis,

DELTA CTA System 42mm diameter cups are

compatible with 42mm DELTA XTEND

Glenospheres

• In more extreme cases, a modular humeral

spacer +9mm can be used

DELTA CTA Revision to Hemi-Arthroplasty

In cases of intra-operative fracture of the glenoid cavity,

or revision of the DELTA CTA Glenoid, for example,

a hemi-arthroplasty may be considered. Intermediate

metallic heads are provided within the DELTA CTA System

to complete this procedure. Two epiphyseal diameters,

36mm and 42mm, are available in standard and +4mm

offset. The hemi heads can be assembled either directly

onto the epiphysis or onto the metallic spacer. These

should be introduced using the humeral head impactor

per the DELTA CTA Surgical Technique (0612-26-500).

POST-OPERATIVE MANAGEMENT

2. Late phase (after 6 weeks)

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.

1. Early phase (0 to 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.

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:

Revision Instruments

6160 DePuy Synthes Joint Reconstruction DELTA XTEND™ Surgical Technique

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.
