1. Neck of 5th Metacarpal
2. Metacarpal Shaft
3. Metacarpal Head
4. Base of Metacarpal Fracture Dislocations
5. MCPJ dislocations
Non operative Management
Accept 45o angulation
- will have finger extensor lag, but will recover
>65
Third most common fracture after hip and distal radius
Neck shaft angle 130o
Head retroverted 20o relative to shaft
Anatomical neck (junction of head and metaphysis)
A: Alignment
B: Bony
C: Canal
D: Disc
S: Soft tissues
1. Correct deformity
2. Restore stability
3. Decompress neural elements if required
Advantage
- defines level of conus
- may need anterior rather than posterior surgery if lesion above conus
