Abstract：Objective To evaluate the curative effect of lateral malleolar anatomical hookplate in the treatment of lateral malleolus fractures.Methods During the period from January 2013 to January 2017，27 patients were treated at our institute using lateral malleolar anatomical hookplate for repair of distal lateral malleolus fracture，the average age was (38±9)years old(range 25 to 55).There were sixteen males and eleven females.The functional rehabilitation of the patients’anklejoints were assessed by the range of motion (ROM)and the Mazurscore retrospectively.Results There were 25 patients were followedup for (31±9)months (range from 19 months to 47 months).At the last followup，the range of motion(ROM)between the healthy sideand the injured side，including flexion，extension，varus and valgus，had no statisticalsignificance(P＞0.05).According to the Mazur ankle scores，there were 17 excellent cases，6 good cases，1 fair case，1poor case，the excellent-good rate was 92.00％，and the scores were (88.64±3.41).Conclusion he treatment of lateral malleolus distal fracture with fibula hook plate has anatomic reduction，firm fixation，easy operation，little stimulation to soft tissue and satisfy early functional exercise，which is helpful to the rehabilitation of ankle function.
