Abstract:
Twenty-seven chronic flexion contractures of the proximal interphalangeal joint were treated with the Compass((R)) hinge external fixator without open surgery. The fixator was removed after a mean of 33 (range, 14-68) days. The mean time from injury to operation was 4 (range, 1-19) years and all patients were reviewed at a mean follow-up of 21 (range, 12-50) months. The mean extension gain was 38 degrees (range, 0-70 degrees), and the mean flexion-extension arc improved by 42 degrees (range, 0-80 degrees). Complications included superficial pin-track infection in 11 cases and pin loosening in four cases.
