- Acceptable Alignment: (phalangeal & metacarpal frx)
- 10 deg angulation in both sagittal and coronal planes except in
metaphysis, where 20 deg angulation in sagittal plane is accepted;
- up to 45 deg angulation in sagittal plane in neck of 5th metacarpal;
- 50% overlap at the fracture;
- no rotation deformity;
- frx that is markedly displaced before reduction did not necessarily
require internal fixation after adequate reduction;
- Stable Frx:
- include closed impacted shaft frx;
- frx w/ little or no displacement;
- most distal phalangeal frxs;
- many isolated metacarpal shaft frxs;
- Unstable Fractures:
- rotated
Spiral Fractures
- comminuted fractures
- severely displaced fractures
- some short
Oblique Fractures
- multiple fractures
- subcondylar proximal phalanx fractures
- palmar base middle phalanx fractures
- fractures with associated extensive soft tissue injury
- displaced articular fractures:
Bennett's and reversed Bennett's
