Summary
Distal radioulnar joint arthritis surgery can cause extensor tendon rupture. Surgeons can prevent this complication by ensuring a smooth bone edge and proper capsule repair during the Darrach procedure.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Rheumatology
Background:
- Symptomatic distal radioulnar joint (DRUJ) arthritis often requires surgical intervention, such as partial or complete distal ulna resection.
- The Darrach procedure is a common surgical technique for treating DRUJ arthritis.
Observation:
- Extensor tendon rupture is a rare but serious complication following the Darrach procedure.
- This complication can arise from sharp bone edges or dorsal capsule disruption at the resected ulnar stump.
Findings:
- A review identified three recent cases of extensor tendon rupture after the Darrach procedure.
- Historical data also indicates this complication, with reports dating back over 30 years.
Implications:
- Surgeons should meticulously ensure the resected ulnar stump is smooth and reconstructed capsule is intact to minimize extensor tendon rupture risk.
- Proper surgical technique, including ensuring free tendon glide, is crucial for successful outcomes after distal ulna resection.
