Pin-tract complications in external fixation of fractures of the distal radius

Abstract

We analyzed retrospectively the rate and outcome of pin-tract complications in 314 unstable fractures of the distal radius, treated with the Hoffmann small-frame external fixator. The overall rate of complications was 27%. The commonest complication (21%) was pin-tract infection, which was treated with oral antibiotics. There were no cases of osteitis. Complications led to premature removal of the fixator in 17 of the cases. Women over the age of 75 years had a significantly higher rate of pin loosening (17%), but not a higher rate of premature removal of the fixator due to complications. 4% of the cases had a pin-site fracture, all women. The rate of pin-tract complications was high, but severe complications were rare, even in old women.
