Summary
Rupture of finger extensor tendons is a rare complication of Madelung's deformity. Surgical resection of the dorsal distal ulna prevented further tendon rupture in a bilateral case.
Area of Science:
- Orthopedics
- Hand Surgery
- Rheumatology
Background:
- Madelung's deformity is a developmental disorder affecting the wrist.
- It is characterized by dorsal and volar subluxation of the distal ulna.
- Extensor tendon rupture is an exceptionally rare complication.
Observation:
- A previously asymptomatic woman presented with bilateral extensor tendon rupture.
- Radiographic evaluation revealed dorsal subluxation of the distal ulna.
- The rupture occurred due to attrition against the subluxed ulna.
Findings:
- The patient underwent resection of the dorsally subluxed distal ulna.
- This surgical intervention aimed to prevent further tendon attrition and rupture.
- Post-operative outcomes were positive, with no further complications reported.
Implications:
- This case highlights an unusual complication of Madelung's deformity.
- Surgical management, including distal ulna resection, can be effective in preventing further tendon damage.
- Understanding this mechanism is crucial for diagnosing and managing similar rare cases.
