| ABSTRACT Obiective To explore the clinical results of surgical treatment of the sustentaculum tali fractures by cannulated screw internal fixation.Methods From August 2012 to June 2017,All 13 patients haved sustentaculum tali fractures with articular surface displaced were treated by cannulated screw internal fixation,including 10 males and 3 females,aged from 26 to 58 years old. All patients treated by internal fixation with two cannulated screw.Clinical effects were evaluated according to the changes of the CT scan from preoperative to postoperative and American 0rthopaedic Foot and Ankle Society(AOFAS)ankle-hindfoot scores. Results All patients got followed up with an average 22 months(ranged, 9 to 70 months).The fractures were stabilized reliably，the bone union at an average time of 12weeks(ranged, 8 to 16 weeks).Obvious improvement of foot function after operation.No incision complications occurred.The width of calcaneus were absolutely improved from preoperative to postoperative,and the distance of middle talar articular changed ﹥2mm. There were no significant differences between the distance of middle talar articular and posterior talar articular after operation ,articular surface were flat on CT scan.The AOFAS scores of 13 patients at 1 year after operation were 77～94.According to the AOFAS, 1 patient was rated as excellent，12 patients were rated as good．Conclution The treatment of sustentaculum tali fractures with articular surface displaced by cannulated screw internal fixation is recommendable,it can effectively re-stored the surface of subtalar joint,and rapid functional recovered. |
