Abstract:
Objective To investigate the risk factors for postoperative deep wound infection after open reduction and internal fixation for closed calcaneal fractures.Methods From January 2014 to January 2017,190 patients with closed calcaneal fracture were treated at Department of Traumatic Orthopaedics,Taihe Hospital.They were 118 males and 72 females with an average of 39.8 years (range,from 18 to 73 years).They were divided into a deep infection group and a non deep infection group according to the presence or absence of deep wound infection in the follow-up period.The 2 groups were compared in the general clinical data.In statistical analysis,the related risk factors were first screened by single factor analysis and followed by multivariate logistic regression analysis to identify the independent risk factors associated with the postoperative deep wound infection in patients with closed calcaneal fracture.Results The 190 patients were followed up for an average of 21.3 months(range,from 13 to 31 months).Postoperative deep wound infection occurred in 11 patients,giving an overall incidence of 5.7％ (11 / 190).The single factor analysis showed that the deep infection group incurred significantly longer time for tourniquet and used significantly more conventional extensile lateral approach than the non deep infection group (P ＜ 0.05).There were no significant differences between the 2 groups in general data,injury cause,fracture type,drainage,or incision closure technique (P ＞ 0.05).The multivariate logistic regression analysis revealed that tourniquet time ＞ 80 min (OR=5.949,95％ CI:1.216～ 29.108,P=0.028) and conventional extensile lateral approach (OR =5.414,95％ CI:1.507 ～ 19.452,P =0.01) were independent risk factors fo r the postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Conclusions Tourniquet time and conventional extensile lateral approach may be the independent risk factors for postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Therefore,it is important to adopt the sinus tarsi approach and control tourniquet time within 80 minutes for prevention of deep wound infection as long as the surgical quality is ensured.
