Treatment of femoral neck fractures with posterolateral mini-incision total hip arthroplasty / 中华创伤杂志

ABSTRACT

Objective To introduce the experience of improved posterolateral mini-incision total hip urthroplasty(THA)in treatment of femoral neck fractures.Methods Of 199 patients(207 hips)treated with preliminary THA from October2002 to January 2005,them were46 patients(46 hips)with femoral neck fractures including31 fresh fractures and 15 old ones,which were then treated with posterolateral mini-incision THA.An observation was done on length of incision,operation time,volume of blood loss,drainage volume,hospital stays,postoperative complications,functional recovery and Harris score.Results All patients were followed up for 14-26 months(mean 17.2 months).The final Harris score during follow-up was(84.1±8.6)points in the fresh fracture group and(85.8±7.6)points in the old fracture group.Pestoperative X-ray showed sound position of the prosthesis.There was no statistical difference upon length of incision,operation time,blood loss,drainage volume and hospital stays between fresh fracture group and old fracture group(P＞0.05).Dislocation occurred in one patient in each group.Conclusion Posterolateral mini-incision THA is proved to be successful in reducing surgical trauma,accelerating rehabilitation and decreasing blood loss and complications for patients with femoral neck fractures.
