Abstract：Objective To investigate the common complications and related factors of minimal invasive internal fixation in treatment of closed calcaneal fractures.Methods The clinical data about 85 patients with closed calcaneal fractures who were treated by minimal invasive internal fixation were retrospectively analyzed.The postoperative complication grade ≥ 2 was served as observation group,and which ＜ 2 was served as control group,then the risk factors of complications were analyzed.Results The univariate analysis showed that the patient's age,smoking history,history of diabetes mellitus,postoperative opportunity,Kirschner wire contactless traction technique to protect soft tissue,selection of drainage manner were closely correlated with the incidence of postoperative complications (P ＜ 0.05).Logistic regression analysis showed that patient's age ≥65 years,long-term smoking history,history of diabetes mellitus,the time from injury to surgery ＜ 5 d,using Kirschner wire contactless stretch technique,without putting drainage device after surgery were risk factors of incidence of postoperative complications after minimal invasive internal fixation.Conclusion For patients with closed calcaneal fractures who are ready to receive minimal invasive internal fixation,it is important to select suitable surgical opportunity,to put drainage device after operation,to protect blood supplying of soft tissue,to prohibit strictly smoking at peroperative period,to treat regularly diabetes mellitus in order to prevent the occurrence of postoperative complications.
