Summary of Reconstructive Hand Surgery for Rheumatic Conditions
Reconstructive Hand Surgery for Rheumatic Conditions
Introduction
The proximal interphalangeal (PIP) joint plays a central role in finger function, particularly pinch and grip. This guide summarizes surgical techniques used to treat symptomatic PIP joints — focusing on synovectomy, fusion, and arthroplasty approaches, exposure strategies, fixation options, and key intraoperative decisions. The goal is to give a concise, practical overview for a Not attending student to understand indications, steps, and technical pearls.
Definition: The PIP joint is the proximal interphalangeal joint between the proximal and middle phalanges of the fingers; it contributes substantially to digital flexion arcs needed for pinch and grip.
Overview of PIP Procedures
- Synovectomy — removal of hypertrophic synovium to prevent progressive deformity and preserve extensor mechanism.
- Fusion (arthrodesis) — indicated when pain and instability cannot be managed otherwise; used to obtain a painless, stable, and aligned finger.
- Arthroplasty (implant joint replacement) — silicone spacers or surface-replacement implants to reduce pain and preserve motion when fusion would be too disabling.
Indications and Decision Making
- Indications for PIP synovectomy: progressive synovitis causing extensor mechanism stretching or risk of boutonnière deformity, relatively preserved joint surfaces.
- Indications for PIP fusion: painful, deformed, or unstable joint where motion preservation would not produce reliable function; chosen flexion angle depends on finger and patient needs.
- Indications for PIP arthroplasty: chronic degenerative or selected post-traumatic arthritis where preservation of some motion is desired and bone stock/ligaments are adequate.
Surgical Exposure and Soft-Tissue Handling
Dorsal exposure principles
- Use a slightly curved dorsal incision over the finger to expose the extensor mechanism while preserving longitudinal dorsal veins and sensory branches.
- Options for extensor exposure:
- Split the central slip in the midline (central longitudinal split).
- Make an interval incision between the central slip and a lateral band, depending on synovial bulging.
- If synovium bulges laterally, reflect the lateral band dorsally by incising the transverse retinacular ligament to reach synovium beneath the accessory collateral ligament.
Definition: Central slip — the central portion of the extensor tendon that inserts on the base of the middle phalanx and helps extend the PIP joint.
Repair and post-op dressing
- Repair the extensor mechanism with absorbable 4-0 suture.
- Apply a conforming dressing with the PIP joint positioned in extension.
- Begin early active motion 1–2 days after surgery; splint in extension except during exercise periods for ~2 weeks.
Proximal Interphalangeal Joint Synovectomy — Technique Steps
- Expose extensor mechanism via dorsal incision; preserve dorsal veins.
- Choose capsulotomy site where synovium bulges.
- Excise hypertrophic synovium sharply or with a small rongeur; apply gentle distal traction and flex the joint to facilitate access.
- For lateral bulging synovium, incise transverse retinacular ligament and reflect lateral band dorsally or incise volar to the collateral ligament to remove volar pouch synovium while protecting the collateral ligament.
- Repair extensor mechanism and start early motion as above.
PIP Joint Fusion — Principles and Techniques
Goals and position
- Primary goal: pain relief and a stable, aligned fingertip.
- Choose fusion angle by finger: index fused in less flexion than middle finger; ring and small fingers fused more (typical range 25–45°). Discuss patient priorities preoperatively.
- Use a sterile goniometer intraoperatively to check angle; initial pin allows measurement before final fixation.

Klíčové pojmy: PIP synovectomy prevents progression to boutonnière by removing hypertrophic synovium and preserving extensors, Choose fusion angle by finger: index ~25°, middle slightly more, ring/small up to 45° based on function, Use a sterile goniometer intraoperatively to verify fusion angle before final fixation, Minimum K-wire size for small-joint fixation is 0.045 inch, Headless self-compressing screws require medullary canal sizing on lateral radiograph preop, Herbert-type screws must have leading threads engage isthmus to avoid toggling in metaphysis, Silicone spacers provide a flexible pseudocapsule but risk hinge failure and particulate synovitis, Surface-replacement implants aim to restore a virtual axis and require minimal bone resection, Preserve collateral ligaments when possible to improve out-of-plane stability, Early active motion after synovectomy (1–2 days) helps preserve PIP function, Burying K-wires allows washing but increases infection/irritation risk and may require OR removal, Augment fusion with bone grafts when erosive bone loss is present
