Summary
Distal scaphoid excision for wrist arthritis can lead to rare flexor tendon ruptures. This case highlights a previously unreported complication following this surgical procedure.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Wrist biomechanics
Background:
- Distal scaphoid excision is a treatment for scaphotrapeziotrapezoid (STT) joint osteoarthritis.
- Potential complications include carpal ligament, cartilage, and radial artery injury.
Observation:
- A single case of a 68-year-old male patient was reviewed.
- The patient had undergone distal scaphoid excision for STT osteoarthritis three years prior.
Findings:
- The patient experienced ruptures of the flexor digitorum superficialis (FDS) and flexor digitorum profundus tendons in the index finger.
- This necessitated flexor tendon reconstruction and eventually a 4-corner wrist fusion due to persistent midcarpal pain.
Implications:
- Flexor tendon rupture is a novel complication associated with distal scaphoid excision for STT arthritis.
- Highlights the need for vigilance regarding tendon integrity after this procedure.
- Suggests potential long-term implications for wrist function and stability.
