Summary
Extensor tendon rupture is a rare complication of Kienböck
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Vascularized Bone Grafts
Background:
- Kienböck's disease involves avascular necrosis of the lunate.
- Complications can include carpal instability and secondary arthritis.
- Extensor tendon involvement is an uncommon sequela.
Observation:
- A comminuted dorsal fragment of the lunate caused attritional rupture of the index finger extensor tendon.
- The patient was an elderly woman with a history of Kienböck's disease.
Findings:
- Surgical excision of the bony fragment was performed.
- Extensor tendon reconstruction using a tendon graft was successful.
- The patient achieved a favorable functional outcome.
Implications:
- This case highlights a rare but significant complication of Kienböck's disease.
- Surgical management involving fragment excision and tendon reconstruction can restore function.
- Emphasizes the importance of considering tendon integrity in advanced Kienböck's disease.
