Summary
This summary is machine-generated.

Evaluating swan-neck deformity requires assessing PIP joint mobility and condition for effective treatment. Options range from fusions and tenodesis for limited motion to salvage procedures like fusion and arthroplasty for severe joint destruction.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Swan-neck deformity is a common condition affecting finger joint mobility.
  • Accurate assessment of the proximal interphalangeal (PIP) joint is crucial for treatment planning.

Purpose of the Study:

  • To outline a logical treatment approach for swan-neck deformities.
  • To categorize treatment options based on PIP joint mobility and radiographic condition.

Main Methods:

  • Evaluation of PIP joint mobility and radiographic status.
  • Categorization of treatment strategies based on the degree of joint motion loss.
  • Review of surgical interventions including DIP joint fusions, dermadesis, flexor tenodesis, manipulation, releases, fusion, and arthroplasty.

Main Results:

  • Fingers with minimal PIP joint motion loss can be treated with DIP joint fusions, dermadesis, or flexor tenodesis.
  • Significant PIP joint motion loss requires initial efforts to restore passive motion via manipulation and releases, followed by restoring flexor tendon excursion.
  • For destroyed PIP joint surfaces, salvage procedures such as fusion and arthroplasty are the primary treatment options.

Conclusions:

  • Treatment for swan-neck deformity should be individualized based on PIP joint assessment.
  • A stepwise approach is recommended, starting with conservative measures and progressing to surgical interventions as needed.
  • Salvage procedures offer viable solutions for advanced cases with joint destruction.
