Abstract：Objective To investigate the related influencing factors on the therapeutic effects of open reduction andinternal fixation (ORIF) in treatment of displaced intra-articular calcaneal fracture (DLACF).Methods Thirty-three patients with DLACF who were treated by open reduction and internal fixation in our hospital were enrolled in the study.According to possible influencing factors on surgical therapeutic effects,patient's age,weight,preoperative angle B,postoperative angle G,preoperative time and Sanders typing were detected and recorded,and the examination results were statistically analyzed.Results The therapeuitic effects of ORIF surgery,among 33 patients with DLACF,18 cases were excellent,12 cases were good,5 cases were all right,2 cases were poor.The patient's weight,preoperative angle B,postoperative angle G,preoperative time had significant effects on surgical therapeutic effects (P ＜ 0.05),however,patient's age had no obvious effects on surgical therapeutic effects.The total excellent rate in patients with type Ⅱ (Sanders classification) was 94.1％,which was 73.3％ in patients with type Ⅲ and 60.03％ in patients with type Ⅳ,there were significant differences among them (P ＜ 0.05).The multivariate Logistic regression analysis showed that body weight,preoperative angle B,postoperative angle G,preoperative time,Sanders typing were influencing factors on postoperative therapeutic effects scoring.Conclusion The influencing factors on the therapeutic effects of open reduction and internal fixation in treatment of DLACF are mainly patient's body weight,preoperative angle B,postoperative angle G,preoperative time and Sanders typing,therefor,these factors should be avoided during surgery to improve surgical efficiency.
