Restoring finger joint motion after loss of extension involves nonsurgical methods like splinting first. Surgical release can improve flexion contracture, but requires close follow-up and physical therapy.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Biomechanics

Background:

  • Proximal interphalangeal (PIP) joint motion is crucial for hand function, relying on intact bony structures, articular surfaces, tendon gliding, collateral ligaments, and the volar plate.
  • Deficiencies in these structures can cause loss of finger joint motion and impaired hand function.
  • Loss of finger extension necessitates treatment, with nonsurgical options preferred before surgical intervention.

Purpose of the Study:

  • To review treatment options for loss of proximal interphalangeal joint motion, focusing on finger extension loss and flexion contractures.
  • To compare nonsurgical and surgical interventions for improving PIP joint function.
  • To discuss the outcomes and risks associated with surgical procedures like external fixation and open surgical release.

Main Methods:

  • Review of current literature on proximal interphalangeal joint contractures and loss of motion.
  • Analysis of nonsurgical treatments including splinting and serial casting.
  • Evaluation of surgical interventions such as external fixators and open surgical release, with a focus on reported outcomes and complications.

Main Results:

  • Nonsurgical treatments should be attempted prior to surgical intervention for finger extension loss.
  • Surgical release typically improves flexion contracture by 25-30 degrees, shifting the arc of motion functionally.
  • External fixators offer improved PIP joint extension but risk reduced flexion and pin site infections.

Conclusions:

  • Treatment for PIP joint stiffness should prioritize nonsurgical methods initially.
  • Surgical release is effective for significant flexion contractures, but requires diligent post-operative care.
  • Arthrodesis or amputation may be indicated for severe deformities or compromised vascular status, rather than motion-preserving procedures.
