Revision as of 01:37, 25 December 2016
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
- Axial compression applied along 3rd metacarpal elicits tenderness
Differential Diagnosis
Carpal fractures
- Scaphoid fracture
- Lunate fracture
- Triquetrum fracture
- Pisiform fracture
- Trapezium fracture
- Trapezoid fracture
- Capitate fracture
- Hamate fracture
Evaluation
- PA and lateral views
- MRI/CT may be required to identify occult fractures
Management
- Short arm thumb spica splint
- Ortho referral
Disposition
- Discharge
