Summary
A rare total palmar trans-scaphoid-lunate wrist dislocation was successfully treated with open reduction, bone grafting, and internal fixation. Long-term follow-up showed no osteonecrosis and near-normal wrist function.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Traumatology
Background:
- Total palmar trans-scaphoid-lunate dislocation is an exceptionally rare and severe wrist injury.
- Prompt and accurate diagnosis is crucial for optimal management and functional outcomes.
Observation:
- This report details a rare case of total palmar trans-scaphoid-lunate dislocation.
- The injury involved a complex disruption of the proximal carpal row.
Findings:
- The patient underwent open reduction, bone grafting, and internal fixation for the dislocation.
- Healing was uneventful, with no signs of osteonecrosis observed at the 70-month follow-up.
- Wrist function was reported as almost normal after the extended follow-up period.
Implications:
- This case demonstrates the potential for successful surgical management and long-term functional recovery in rare, severe wrist dislocations.
- Bone grafting and internal fixation can provide stable fixation and promote healing in complex carpal injuries.
- Preservation of wrist function and avoidance of osteonecrosis are achievable goals with appropriate treatment strategies.
