Abstract：Objective To compare the clinical efficacy of minimally invasive incision hollow screw intr-amedullary fixation and open ruduction plate fixation for middle clavicular fractures.Methods Forty-two cases of middle clavicular fracture admitted into our department from Jan.2012 to Jan.2014 were divided into open reduction group and open reduction group according to the surgical methods utilized. Among them 17 cases were Type 91.22A1,15 were Type 91.22A2 and 10 were Type 91.22B1.The general surgery conditions,shoulder function Constant-Murley score and Neer score,incidence of postoperative complications of the two groups after operation were compared.Results The operative time,blood loss,hospital stay and fracture healing time in the hollow screw group were significantly lower than those in the open reduction group(P<0.01).The Constant-Murley scores and daily life,pain,activity and Neer scores in the hollow screw group were significantly higher than those of the open reduc-tion group(P<0.01).Moreover,the incidence of postoperative complications in the hollow screw group was signifi-cantly reduced compared with that in the open reduction group(χ2 =4.2667,P=0.0389).The postoperative inci-dence of malunion had no significant difference(χ2 =0.5818,P=0.4456>0.05).Conclusion In comparison with open reduction and plate fixation method,minimally invasive hollow intramedullary screw fixation for middle cla-vicular fracture is less invasive,achieves faster postoperative recovery,better shoulder function,as well as less post-operative complication incidence.It is worthy of clinical application.
