Examination
- TTP along affected metacarpal
- Flexion at MCP is difficult
- Assess for extensor dysfunction; patient may exhibit "pseudo-clawing" during attempts at finger extension
- Assess angulation
- >10 deg in 2nd and 3rd and >20 deg in 4th and 5th metacarpal shaft fractures requires reduction
- Assess rotational alignment
Imaging
- Oblique fracture are more prone to shorten and rotate
- Transverse fracture generally stable (particularly isolated 3rd or 4th MC shaft fx)
Differential Diagnosis
Hand and Finger Fracture Types
Treatment
- Ulnar Gutter Splint or Radial Gutter Splint]
- Acute reduction indicated if there is pseudo-clawing or significant angulation
- Closed reduction generally corrects angulation but typically does not restore length
Disposition
- Refer:
- Malrotation
- Comminution
- Shortening > 5mm (refer all shortening if not familiar with fracture management)
- 2 or more metacarpal fractures
- Unacceptable angulation
- Long oblique fractures
