2. Scope
1. PIPJ and its importance
2. Common causes of PIPJ arthritis
3. Surgical options

4. Summary
3. Anatomy and Function
• Function
• Locus of the finger – joint with the largest ROM
in the hand
• 85% of grasping capability of the hand
• Anatomy
• Complex: mainly hinge (with varying centres of
rotation)
• Also some lateral motion and rotation
• Osseous anatomy
• Collateral ligaments – Proper and accessory
collateral ligaments
• Volar plate & checkrein ligament

4. PIPJ Arthritis - Causes
• Post-traumatic arthritis
• Osteoarthritis
• Less common in hand compared to DIPJ
and 1st CMCJ
• Inflammatory arthritis
• Others – gout, infection etc

6. I. Interpositional Arthoplasty
• Alternative to fusion or implant arthroplasty
• Different techniques
• Advantages:
• Motion preserving
• Biological solution
• Can still do fusion (without much shortening)
• Limited data and adoption
• Selected situations – need good soft tissue,
collaterals, alignment
• Selected patients – lower demand
• ?Reliability

Ellen Lee)
Screw only (Leibovic 2007)
9. Technical considerations
• Angles
• Shorter -> straighter
• Radial to ulnar
• Patient needs
• Bone cuts

10. Unclear which technique is better
• Biomechanics
• Capo 2014:
• Lister’s, 90-90 wiring, Tension-band, Plate & screws, IM
device
• IM device & Plate/Screws best Ultimate strength and
stiffness
• Kovach’s 1986:
• Cross-wire, Tension-band wiring, Lister’s technique
• Figure of 8 best in AP bending and torsion

11. My favored choice – Tension band wiring
• Fast
• Reliable
• Inexpensive and non-obtrusive
implant
• For technique – see Uhl 2007 in
resources

12. Results of PIPJ fusion
• “Surgical Results”
• Fusion rates > 85% (see Jung 2018)
• Complication rates low
• Hardware prominence ~9% (Jung
2018)
• Malunion, fracture, infection, skin
problems
• Functional Results
• Pain relief
• Better strength
• Loss of motion: average ~ 30°
(Vitale 2015)

14. Silicone Arthroplasty
• PIPJ and MCPJ
• Many years experience
• Functions as a spacer
• Rather than a true joint
• Many patients satisfied with it
Moment about the PIP joint axis. (A) In hinged arthroplasty, flexion moment about
the PIP joint requires force (F) with moment arm (X). The moment arm from a
flexed position (X′) decreases due to dorsal displacement of the center of rotation
requiring an increase in extension force (F′) to return the PIP joint to neutral.

15. Long term outcomes of silicone arthroplasty
• Good
• Pain relief (VAS 0.4/10)
• Patient satisfaction
• Implant survival (90% at 10 years)
• BUT
• ROM unchanged
• Radiographic changes progress
• Deformity
• Fracture
• Revisions/removal (3/38)
• For older, lower demand patients
• Average age: 60
• Mostly females

16. Metal Implant Arthroplasty
• Newer than silicone
• Pain relief
• Range of motion not markedly
increased
• Complications higher than silicone
• Infection
• Squeaking
• Contractures
• Dislocation
• Subsidence
• Limited indications (Adkinson 2014)
• “Young patients with post-traumatic
arthritis, no angular deformity, adequate
soft tissue coverage”

18. Summary of arthroplasty options
Type Indications Advantages Disadvantages
Silicone MCPJ and PIPJ arthritis (OA,
RA, post-traumatic)
Pain relief, technically
straightforward
Minimal improvement in range of motion
(better at MCPJ compared to PIPJ),
subsidence, implant fracture
PIP-SRA/
Nakashima
MCPJ and PIPJ arthritis (OA,
post-traumatic)
Pain relief, minimal
bone resection
(maintain collaterals)
Minimal improvement in range of motion,
subsidence, loosening, implant fracture
Pyrocarbon MCPJ and PIPJ arthritis (post-
traumatic, rarely OA) with
adequate soft tissue support
Pain relief
(controversial),
improved grip/pinch
strength
Minimal improvement in range of motion
(better at MCPJ compared to PIPJ),
subsidence, dislocation, implant fracture
Autologous Skeletally immature patients
with MCPJ and PIPJ trauma or
adults with contraindication
for prosthesis (inadequate
soft tissue support, large
bone deficit, previously failed
prosthesis)
Allows future growth
and composite
reconstruction
Minimal improvement in range of motion,
high complication rate, need for secondary
surgery, technically challenging

19. Fusion vs Implant Arthroplasty
• Not well studied
• Both currently have a place in
treatments – differing patients, clinical
problem, functional needs
• Outcomes studied
• Pain relief
• Range of motion
• Strength
• Better improvement in lateral pinch strength
in arthrodesis (Pelligrini 1990)
• Complications
• Implant arthroplasty late complications

20. Take Home Message
• Arthrodesis of PIPJ is a reliable operation for pain relief and correcting
deformity
• Main issue is total loss of motion of PIPJ
• Functional assessments comparable to implant arthroplasty
• Candidates: younger, male, strength requirement, lack of bone stock/stability
• Implant Arthroplasty
• Prioritizes motion
• Also provides good pain relief
• Motion does not increase, decreases over time
• More complications and re-operations
• Silicone implants well established; metal/surface replacement implants
evolving
