Effect observation on humeral greater tuberosity fracture by minimally invasive cannulated screw and open reduction and plate fixation

Objective To investigate the clinical efficacy and safety of minimally invasive cannulated screw and open reduction and plate fixation in the treatment of humeral greater tuberosity fracture.Methods 50 patients with greater tuberosity fracture diagnosed by X-ray or CT in the Second Department of Orthopedics in the 180th Hospital of Peo ple's Liberation Army from December 2009 to December 2012 were studied.50 cases were divided into two groups randomly.25 cases treated by minimally invasive cannulated screw were as the observation group.The other 25 cases treated by open reduction and plate fixation were as the control group.The length of incision,operation time,intraop erative blood loss,and hospitalization days were observed.According to Neer grading system,efficacy was evaluated,and fracture healing was observed.Results The observation group had shorter operation time,less blood loss,and shorter hospitalization days than the control group,showing significant differences(P 0.05).Superficial infection occurred in 3 cases(12%) of the control group.The time of fracture healing was(9.4 ±1.4) weeks in the observation group,and was(14.9 ±1.2) weeks in the control group,showing significant difference(P 0.05).The good rate of 92.0%(23/25) in the observation group compared with the good rate of 56.0%(14/25) in the control group,with a sta tistical difference(P 0.05).Conclusion Compared with open reduction and plate fixation,minimally invasive cannu lated screw for greater tuberosity fracture has the advantages of simple operation,less trauma,less blood loss,and good shoulder function recovery,which is worthy of clinical promotion.
