Summary
This case report details a rare perilunate fracture-dislocation involving a transverse lunate fracture. Surgical repair with screw fixation and ligament reinsertion led to a full recovery for the patient.
Area of Science:
- Orthopedic Surgery
- Trauma Care
- Radiology
Background:
- Perilunate fracture-dislocation is an uncommon wrist injury.
- Diagnosis often requires advanced imaging like CT scans.
- Ligamentous integrity is crucial for wrist stability.
Observation:
- A 24-year-old male sustained a perilunate fracture-dislocation after a motorcycle accident.
- Imaging revealed a transverse lunate fracture with associated perilunate ligament damage.
- A dorsal surgical approach was utilized for fracture reduction and ligament repair.
Findings:
- The case presents the first documented instance of a transverse lunate fracture within a perilunate fracture-dislocation.
- Surgical management included double screw fixation and ligament reinsertion, augmented by temporary K-wires.
- Successful anatomical reduction and stable fixation were achieved.
Implications:
- This case expands the understanding of rare wrist fracture-dislocation patterns.
- It highlights the effectiveness of surgical intervention in managing complex perilunate injuries.
- Restoration of wrist function and return to normal activities were achieved within six months post-surgery.
