Summary
Extensor tendon dislocation at the middle finger's metacarpophalangeal joint can occur due to ulnar translation forces from end-to-side tendon transfers. Surgeons should consider technique modifications or alternative methods to prevent this complication.
Area of Science:
- Hand surgery
- Orthopedic surgery
- Reconstructive surgery
Background:
- Extensor tendon injuries often require surgical reconstruction.
- End-to-side tendon transfers are a common reconstructive technique.
- Potential complications of tendon transfers need careful consideration.
Observation:
- A case of extensor tendon dislocation at the metacarpophalangeal joint of the middle finger is presented.
- The dislocation appeared to be associated with an ulnar translation force generated during an end-to-side tendon transfer.
Findings:
- Ulnar translation force during end-to-side extensor tendon transfer may contribute to metacarpophalangeal joint dislocation.
- This complication may be more likely when unfavorable factors for the end-to-side transfer technique are present.
Implications:
- Surgical technique modifications or alternative methods for extensor tendon reconstruction should be explored.
- Preventing extensor tendon dislocation is crucial for optimal functional outcomes after hand surgery.
- Further research into tendon transfer biomechanics and complication avoidance is warranted.
