Summary
Transscapho-transcapitate fracture dislocation is a rare wrist injury caused by high-energy trauma. Surgical intervention is recommended if closed reduction fails to restore stability and prevent functional loss.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Transscapho-transcapitate fracture dislocation is a rare perilunate dislocation.
- This injury results from acute high-energy wrist trauma, including hyperdorsiflexion and longitudinal compression.
Observation:
- The injury involves concurrent fractures of the scaphoid and capitate neck.
- A characteristic finding is the rotation of the proximal capitate fragment up to 180 degrees.
Findings:
- The study reviews four cases, detailing their treatments and discussing the underlying mechanism.
- Closed reduction may not achieve a stable anatomic reduction in all cases.
Implications:
- Surgical reduction and internal fixation of the scaphoid and capitate are recommended when closed reduction is insufficient.
- Prompt surgical management is crucial to prevent long-term wrist dysfunction and loss of function.
