Objective To evaluate the time,method and the clinical outcome of operative management of displaced intra- articular fractures of the calcaneus with calcaneal locking plate(LCP).Methods Thirty- two fractures in 31 patients(30 male including 1 bilateral ,1 female) were treated with open reduction and internal fixation (ORIF) of intra- articular calcaneal fractures using LCP through an ex-tended L- shaped lateral approach.The average age of thirty- one patients was 32 years (range,18 to 50 years).All fractures were close in-juries,and Sanders classification was determined. Result Twenty- seven of these fractures in 26 patients were followed up.All fractures had greater than three months follow- up ,(range 6 to 12),and these have been followed to fracture healing.The Bohler angle was recov-ered from less 10°preoperative to 20°~40°postoperative and the Gissane angle was recovered from less 100°to 120°~145°. No patient sustained lateral impingement syndrome or soft tissue complications. With postoperative plain radiographs, the reduction of fractures was maintened, and all of internal fixation were success. According to Maryland et al foot score execellent/good 92.6%,fair 7.4%. Conclusion The application the LCP through extend lateral approach is proved to be an effective treatment for displaced in-tra- articular calcaneal fracture by grasping correct opportunity of operation and perfect operative technique, offering the combination of good reduction and early rehabilitation.
