Abstract
Objectives: The purpose of this study was to prospectively evaluate patients who had closed reduction and external fixation of displaced intra-articular calcaneal fractures with supercutaneouscalcaneal locking plates used as external fixators. Methods: Between January 2014 and June 2015, 30 cases were performed. According to the sanders classification system, 3cases were type II, 14 cases each of type III and 13 cases type IV. Three months after surgery, when imaging studies confirmed bone union, the plates and screws were removed under general anaesthia. The average time of follow-up was 8.4 months (range, 6 to 14) months. Results: six cases (20%) had superficial pin tract infections. The reduction of the articular surface and bone union were good. Ten cases developed heel pain as a result of peroneal tendinitis and malunion. The preoperative x-rays of the 30 patients had an average bohler{u2019}s angle 10.57{u25E6}± 4.8 and gissane{u2019}s angle of 143.38{u25E6}±22.79. Their postoperative x-ray films demonstrated that the bohler{u2019}s angle improved to 29.07{u25E6}± 5.9and the gissane angle to 132.33{u25E6}±22.7 (p<.01). According to the ankle-hindfoot clinical rating system of the American orthopaedic foot and ankle society (AOFAS), their average score was 87.3±14.60 (range, 51 to 100) points. Conclusion: Using a supercutaneous calcaneal locking plate to treat calcaneal fractures caused limited tissue irritation, a low rate of local skin infection, satisfactory reduction of the articular surface, stable fixation, and an overall reduced cost
