Abstract

We describe the treatment of 74 patients with phalangeal condylar fractures. Twelve patients presenting with undisplaced fractures were initially treated nonoperatively; of these, five displaced, requiring fixation. The remaining seven patients, all children, united uneventfully. Sixty-two patients presenting with displaced fractures were treated with internal fixation using a single lag screw through a lateral approach. The patients were treated semi-electively on a day surgery unit. Twenty-seven patients with unicondylar fractures, all operated on within 2 weeks of injury, regained full range of movement. Thirty-eight patients had loss of extension (range 10-35°) with fixed flexion contractures at the proximal interphalangeal and thumb interphalangeal joints and extensor lag at the distal interphalangeal joints (overall mean extension loss 10°). Although fixation was technically easier during the first week, a delay of 2 weeks before fixation made little difference to the outcome. In our experience, fractures can be taken down and fixed internally even 8 weeks after injury. If nonoperative treatment is initially embarked upon, close monitoring is required with weekly radiographs up to 3 weeks, as these fractures will frequently displace.

Keywords: Condylar fracture; internal fixation; lag screw; semi-elective.
