[Isolated traumatic dislocation of the extensor carpi ulnaris tendon]
Summary
This study details post-traumatic extensor carpi ulnaris tendon dislocation, a rare wrist injury. Surgical repair is recommended for impaired function to reconstruct the tendon sheath, yielding satisfactory outcomes.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Disorders
- Trauma Care
Background:
- Extensor carpi ulnaris (ECU) tendon dislocation is a rare injury.
- Often associated with wrist trauma, even without obvious bony lesions.
Observation:
- The authors report one case and review eleven additional cases from the literature.
- This injury pattern should be considered in patients presenting with wrist trauma without fractures.
Findings:
- Surgical intervention is indicated for significant functional impairment or habitual dislocation.
- The primary surgical goal is the reconstruction of the disrupted tendon sheath.
- Reported outcomes following surgical management are generally satisfactory.
Implications:
- Highlights the importance of suspecting ECU tendon dislocation in wrist trauma evaluations.
- Emphasizes surgical reconstruction for restoring wrist function.
- Contributes to understanding and managing this specific tendinous injury.
