Summary
This case report details a rare perilunate dislocation involving the transstyloid, transscaphoid, and transtriquetral bones. Surgical intervention led to successful fracture healing and restored wrist function within two years.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Perilunate dislocations are uncommon wrist injuries.
- The transstyloid, transscaphoid, transtriquetral pattern represents an extremely rare variant.
Purpose of the Study:
- To report a unique case of a delayed presentation of transstyloid, transscaphoid, transtriquetral perilunate dislocation.
- To describe the successful surgical management and outcomes of this rare injury.
Main Methods:
- Open reduction and internal fixation performed via a dorsal approach.
- Utilized Joshi's Distraction System to aid in reduction.
- Follow-up included radiographic assessment of scaphoid fracture healing and clinical evaluation of wrist function.
Main Results:
- Successful anatomical reduction and stable internal fixation achieved.
- Scaphoid fracture demonstrated complete healing by 16 weeks post-operatively.
- Patient exhibited good wrist range of motion and no discomfort at the 2-year follow-up.
Conclusions:
- This case highlights the feasibility of surgical management for complex, delayed perilunate dislocations.
- Prompt and accurate surgical intervention can lead to excellent functional recovery in rare carpal injuries.
- Joshi's Distraction System may be a valuable adjunct in managing complex carpal dislocations.
