Indications:
•Scapholunate Advanced Collapse
•Scaphoid Nonunion Advanced
Collapse
• Kienbock’s disease with carpal
collapse
•Other arthritides of the wrist

Proximal Row Carpectomy
Benefits:
•Pain relief
•Motion preserving
•Grip strength improvement
Contraindication:
•Significant capitate arthritic
degeneration
since the new articulating
surfaces will be the capitate
and lunate fossa of the
radius . . .
Proximal Row Carpectomy
Proximal Row Carpectomy
•With an arthritic
capitate, other
procedures should
be chosen:
scaphoid excision
and midcarpal
fusion or total wrist
fusion

•When there is minimal involvement (ie. < 3
mm, J Hand Surg 1990), PRC or PRC with
capsular interposition may still benefit the
patient

CARTILAGE
Hunter stated in 1743 that,
“from Hippocrates down to the
present age, we shall find, that an
ulcerated cartilage is universally allowed to be a very
trouble-some disease; that it admits of a cure with
more difficulty than a carious bone; and that, when
destroyed, it is never recovered.”
What is the limiting problem?
(Philos Trans R Soc London B Biol Sci 1743)
•Is a unique tissue lacking vascular, nerve and lymphatic supply
•Lack of vascular and lymphatic circulation thought to be one
reason for the poor intrinsic capacity to heal
•No inflammatory response elicited unless the subchondral
bone is violated
•Any healing is with fibrocartilage which lacks the
biomechanical properties of hyaline cartilage

Symptomatic Treatment
•Lavage
o allows removal of loose articular particles, released enzymes, and
inflammatory mediators
o effect only temporary, underlying pathology not addressed
•Debridement
oRemoves mechanical symptoms
oSymptomatic relief, 80% improvement in first year with
gradual decline
How have other fields dealt with this
problem?
(Surgery of the Knee 2001)
•Multiple Drilling
–Pridie 1959
–Insall showed 40% success at 6 yrs
•Multiple Microfracturing
–Introduced by Steadman and Rodrigo
–75% success at 7 yrs
•Abrasion Arthroplasty
–Introduced by Johnson who showed success
rate of 77% at 2 yrs

Osteochondral Autografting
•Matsusue first reported in 1993
•Hangody reported a 2 – 5 yr follow-up with good
or excellent results in 86% to 90% of cases
•Histologic evaluation from animal studies show:
1. Survival of transplanted hyaline cartilage
2. Composite of 80% transplanted hyaline cartilage and
20% fibrocartilage
3. Deep matrix integration at the recipient site

•Sandow in 1998 reported
using rib bone/cartilage
autografts in 22 pts for
deficiency of the proximal
scaphoid due to fx or
necrosis
•Found good to excellent
results at median 24 mos
follow-up with the use of the
costo-osteochondral
autograft (J Hand Surg Br 1998)
Osteochondral Autografting
•Salon reported in 2003, 2 cases of
Kienbock’s disease in which peri-lunate
chondral lesions contraindicated classical
PRC or 4 corner arthrodesis
•In one case the lunate fossa of the radius
was damaged
•An osteochondral graft was harvested from
the triquetrum and implanted into the fossa

•Identify patients in whom PRC was planned,
but found to have capitate chondrosis
intraoperatively
•Utilize the resected scaphoid, lunate, and
triquetrum as sources of osteochondral grafts
•Osteochondral autograft these arthritic lesions
Osteochondral Autografting in PRC
To date:
•5 patients have undergone grafting to their
capitate
•Chondrosis rated: Grade 3 in three pts, grade
3-4 in two pts

Osteochondral Autografting in PRC
Summary:
•Osteochondral autografting can be successfully
done in the PRC with capitate chondrosis
•The resected carpal bones provide an adequate
source of autograft
•PRC with osteochondral autografting extends the
indications of PRC and
•broadens the treatment options for arthritides of
the wrist

Thumb Carpometacarpal
Arthroplasty with Ligament
Reconstruction and
Interposition Costochondral
Arthroplasty
Thomas Trumble M.D., Gregory
Rafijah M.D., Dennis Heaton
MSPA,PA-C
Overview
•Multiple techniques currently available for
stabilization, and reconstruction of the basal
joint of the thumb.
•Ultimate goal is to provide substantial pain
relief while maintaining TM height, stability,
and overall strength and function.
Demographics
•58 patients; 66 thumbs.
•Eaton Stage III STT
sparing pattern OA.
•Age range 40-88 years
•48 female, 10 male.
•No patients were insulin
dependent diabetics, or
suffered from
inflammatory
arthropathies.
10/14/2013

Technique
•Curvilinear incision is
made along the volar
radial aspect of the
thumb CMC joint. EPB
tendon, DRSN, and deep
branch of the radial
artery are carefully
dissected and retracted
volarly and dorsally of
the incision .
Technique
•The capsule including,
including the APL
insertion, are sharply
dissected off the
metacarpal, and later
reattached with
braided, non-
absorbable, sutures
through drill holes.
Technique
• An arthrotomy is
performed and the STT
joint is inspected to
confirm that it is free of
degeneration.
•The trapezium is then
partially resected using
an oscillating saw.

Technique
-The FCR tendon is split
longitudinally, and a
length of 12cm is
harvested through a
longitudinal incision at
the junction of the distal
medial thirds of the
forearm.
-Drill holes are placed
from the base of the
metacarpal to the radial
aspect of the thumb
metacarpal, and from
the palmar surface of
the trapezium to the
distal articular surface.
Technique
-The FCR tendon is split
longitudinally, and a
length of 12cm is
harvested through a
longitudinal incision at
the junction of the distal
medial thirds of the
forearm.
-Drill holes are placed
from the base of the
metacarpal to the radial
aspect of the thumb
metacarpal, and from
the palmar surface of
the trapezium to the
distal articular surface.

Technique
•A costochondral
allograft is shaped into
a disc to fit the
dimensions of the
resected portion of the
trapezium.
Technique
•22 gauge cerclage wire
is used to weave the
FCR tendon through
the trapezium, the
allograft cartilage, and
the metacarpal. The
tendon is then sutured
back on itself with a
non-absorbable
braided suture.
Post-operative
•0-6 weeks:The patient is placed in a forearm
based thumb spica cast
•6-12 weeks: A removable splint is then fitted,
and the patient begins AROM of the MCP,
and abduction and rotation of the CMC.
PROM is not started to avoid stress to the
ligament reconstruction.
•At 8- 10 weeks unrestricted thumb motion is
started.

Results
•DASH questionnaires were completed by each
patient.
•Grip strength and lateral pinch.
•TM height.
•TM subluxation.
•Radial abduction
•Palmar abduction.
•MCP ROM
•IP ROM
Results- Radiographic
•TM Height is measured by
taking the distance from
PA radiographs.
•Measurments are taken
from the proximal edge of
the trapezium to the
distal end of the
subchondral bone of the
metacarpal.
•The proximal phalanx of
the thumb was used as a
comparative standard.
Outcomes
•Avg. DASH postop was 11
•Grip increased by 32%
•Pinch increased by 38%
•TM height well maintained (53.1mm pre; 52.9mm
post.)
•TM alignment maintained, minimal
subluxation.(0.21mm pre; 0.22mm post.)
•Radial abduction increased by 3˚ (± 6°)
•Palmar abduction increased by 1˚ (± 8°)
•MCP and IP ROM did not significantly increase or
decrease

Outcomes
•Postoperative pain relief and pinch/grip
strength had a direct correlation with patient
satisfaction.
•Grip and pinch improved with maintenance of
TM height and decreased TM subluxation.
•DASH score decreased as function and
stability were maintained, as evident in the
maintenance of pinch, grip, and overall TM
stability.
Complications
•1 patient in the series progressed to develop
stage IV OA ofthe STT joint.
•A complete trapeziectomy was performed. A
silastic tie-in prosthesis was used to maintain
TM height. At one year follow up, the patient
had excellent pain relief, and was able to
return to all pre-operative activity.

Discussion
•Research published by Luria et al, entitled,
“Biomechanic Analysis of Trapeziectomy,
Ligament Reconstruction, and Tie-In
Trapezium Implant Arthroplasty for Thumb
Carpometacarpal Arthritis: A Cadaver
Study.”(J. Hand Surg. 2007;32A 697-706)
Thumb Stability and Function
•Conclusions: Interposition arthroplasty to
maintain height and ligament reconstruction
for stability provided the most stable
construct.

Osteochondral Autograft
Transplantation for Articular
Defects in the Hand and Wrist
Disclosures
I have no conflicts of interest.
Purpose
•The osteochondral autograft transfer system
(OATS) procedure has been described for
osteochondral defects
•i.e., knee/talus
•Hypothesize that this procedure can be used for
articular defects in the hand and wrist, with good
functional results
10/11/2013

Background
Hyaline cartilage has a poor intrinsic healing capacity
treatment of focal osteochondral defects remains a challenging
problem
Osteochondral defects in the hand and wrist are
relatively infrequent injuries and often present in young
patients with high levels of activity or trauma
No gold standard of treatment
Joint preserving techniques
Debridement, microfracture, ACI, OATS
Salvage techniques predictable for pain relief
Expense of strength/motion
OATS advantages
Hyaline cartilage transplantation
Low morbidity
Methods
Retrospective chart review of four male patients
Treated with an OATS procedure for an articular
defect of their hand or wrist
May 2010 and February 2011.
Avg age: 30 y/o
All pts had failed months to years of conservative
management
Methods
Injuries consisted of osteochondral defects in:
proximal lunate (2)
proximal scaphoid

Technique for lunate/scaphoid injuries
Diagnostic wrist arthroscopy initially used to
assess the articular surface for carpal injuries
(patients #1-3)
No distal radius lesions noted
Adhesions debrided
3rd/4th compartment extensor interval
approach used and graft tapped into position
using press-fit technique into recipient site
Articular congruity confirmed via direct
visualization and fluoroscopy
Full ROM achieved with no crepitus
Technique for MC head injury
EDC/EIP interval and dorsal capsulotomy utilized
Osteophyte removed
Base of proximal phalanx uninjured
Donor/graft site technique same as for carpal
injuries
Direct/fluoroscopic visualization again confirmed
articular congruity

Post-op Protocol
Active range of motion was initiated following the
first post-operative visit
Removable splint for comfort
WBAT to lower extremity
Strengthening w/ formal OT/PT began at 4 weeks
post-operatively
Post-operative radiographs were obtained at 6
weeks

OATS Procedure Conclusions
•Viable treatment option for the treatment of hand and
wrist osteochondral defects in young, active patients
who have failed conservative management
•Technically demanding
•Incorporates hyaline cartilage plug into the defect site
•Capabilities of regrowth/regeneration7
•Biomechanically superior to fibrocartilage9
•Successful outcomes:
•congruent articular surface is achieved
•motivated patient is able to complete an appropriate course of
occupational hand therapy
