Background
- Isolated lunate injuries are rare
- Occurs via FOOSH mechanism
- Blood supply enters distal end - proximal fracture fragment at risk of avascular necrosis (Kienbock’s disease)
Clinical Features
- Tenderness elicited by axial compression applied along 3rd metacarpal
Differential Diagnosis
Carpal fractures
- Scaphoid fracture
- Lunate fracture
- Triquetrum fracture
- Pisiform fracture
- Trapezium fracture
- Trapezoid fracture
- Capitate fracture
- Hamate fracture
Evaluation
- Hand x-ray (PA and lateral views)
- MRI/CT may be required to identify occult fractures
Management
Disposition
- Discharge with referral to orthopedic surgery
