Chronic palmar dislocation of proximal interphalangeal joints

|March 1, 1986
Summary
Operative reduction and extensor mechanism reconstruction successfully restored mobility in seven patients with chronic palmar proximal interphalangeal joint dislocations. This surgical approach offers a preferable alternative to arthrodesis for selected individuals.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Joint reconstruction
Background:
- Chronic palmar dislocations of proximal interphalangeal (PIP) joints present a significant challenge in hand surgery.
- Previous treatment options may have limitations in restoring full joint function.
Observation:
- This study describes seven patients with chronic palmar PIP joint dislocations.
- Dislocation duration varied from 4 weeks to 19 months.
Findings:
- All seven patients achieved satisfactory mobility following operative reduction and extensor mechanism reconstruction.
- Average PIP joint motion was 57.1 degrees, with 29.3 degrees of distal interphalangeal (DIP) joint motion.
Implications:
- Surgical reconstruction of the extensor mechanism is an effective treatment for chronic palmar PIP joint dislocations.
- This operative method is a viable and potentially superior alternative to arthrodesis in carefully selected patients.
- Restoration of functional joint mobility is achievable even in chronic cases.
