Open half-pin insertion for distal radial fractures

Twenty-two patients with unstable distal radial fractures were treated with external fixation using the open technique for half-pin insertion. Of the final study group of 19 patients, 7 (37%) demonstrated early pin-tract drainage, which resolved within 2 weeks after insertion. No pin loosening, pin change, pin breakage, infection, dorsal sensory nerve entrapment or irritation, tendon injury, or additional radial fracture occurred. Wrist range of motion in flexion/extension was 51/47 degrees, and the grip strength ratio (injured versus non-injured side) was approximately 61% on follow-up (average, 8 months). The open technique has proved efficacious in reducing complications associated with external fixation.
