Summary
Lateral band translocation effectively corrects swan-neck deformity by repositioning a tendon. This surgical technique restores finger joint function, improving flexion and eliminating hyperextension without complications.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Reconstructive surgery
Background:
- Swan-neck deformity involves dorsal joint subluxation.
- This condition significantly impairs hand function and finger dexterity.
- Previous surgical treatments have varying success rates and potential complications.
Purpose of the Study:
- To evaluate the efficacy of lateral band translocation for correcting swan-neck deformity.
- To assess the functional outcomes and complication rates of this surgical technique.
Main Methods:
- Lateral band translocation procedure described.
- Thirty fingers with swan-neck deformity were treated.
- Preoperative hyperextension averaged 16 degrees.
Main Results:
- All swan-neck deformities were corrected postoperatively.
- Average flexion contracture was 11 degrees.
- Preoperative flexion range was regained or improved; no recurrences or complications observed.
Conclusions:
- Lateral band translocation is a simple and effective treatment for swan-neck deformity.
- It offers an attractive alternative to existing surgical procedures.
- The technique demonstrates high success rates with no adverse events.
