- Can occur as isolated fracture or in conjunction with other injuries
Pathophysiology
- Trauma with wrist in ulnar deviation and supination
- Radiocarpal ligaments avulse radial styloid from metaphysis
- Can be seen in conjunction with Lunate Dislocation, Perilunate Dislocation or other carpal instability

Clinical Features
- General: Physical Exam Wrist
- Typically swelling, ecchymosis, deformity
- Tenderness to palpation
Evaluation
Radiographs
- Standard Radiographs Wrist
- Findings can be subtle
- May be proximal displacement of lunate and interruption of carpal arc
CT scan
- Important to evaluate intra-articular component
MRI
- Evaluate for soft tissue injuries
Classification
- N/A
Management
Nonoperative
- Generally can be managed nonoperatively if no other co-occurring injuries
- Splint: Radial Gutter Splint
- Cast: Radial Gutter Cast
Operative
- Indications
- Open
- Carpal instability
Return to Play
- Nonoperative will require at least 6 weeks
- Surgically managed cases at the discretion of the surgeon
Complications
