- Location:
- distal 1/3 : 75%
- middle 1/3 : 18%
- proximal 1/3: 7%
- Indications for Open Treatment:
- all displaced, unstable fractures of the radius and ulna in adults;
- all displaced fractures of the radius with greater than 10 deg of angulation or w/ subluxation of proximal or distal R-U joint
- isolated fractures of the ulna with angulation greater than 10 deg;
- all Monteggia and Galeazzi fractures
- open fractures;
- if a Compartment Syndrome requires fasciotomy;
- Malalignment of radius or ulna in forearm will impair ROM of the forearm;
- 10-deg angulatory deformity results in 18% loss of pronation-supination, & 15-deg angulatory deformity resulted in 27% loss of forearm rotation;
- angulation > 20 deg, or any rotational deformity, significantly impaired forearm rotation;
- deformity at mid-shaft is more limiting than distal forearm deformity
