Summary
An extremely rare capitate dislocation occurred after a severe hand crush injury. Surgical reduction and fixation led to a successful outcome with full hand function and no pain after 44 months.
Area of Science:
- Orthopedic surgery
- Trauma care
- Hand surgery
Background:
- Capitate dislocations are exceptionally rare injuries.
- Traumatic hand injuries require prompt and accurate diagnosis.
Observation:
- A case of isolated palmar open dislocation of the capitate is presented.
- The injury resulted from a crush injury during an all-terrain vehicle rollover.
- The capitate was fully dislocated with soft-tissue attachments and a significant open wound.
Findings:
- Surgical reduction and percutaneous fixation were performed.
- The procedure resulted in a successful anatomical reduction.
- Long-term follow-up at 44 months showed excellent functional recovery with good range of motion and no pain.
Implications:
- This case highlights the importance of recognizing rare carpal injuries.
- Prompt surgical intervention is crucial for favorable outcomes in capitate dislocations.
- Successful management can restore full hand function after severe trauma.
