Influence of femoral neck shortening after fracture fixation in the aged patients

Objective To explore the old femoral neck fracture fixation postoperative neck shortening of the influencing factors,so as to provide reference for clinical treatment.Methods 120 elderly patients with fracture of the femoral neck in our hospital from June 2009 to October 2011,all patients were given kwire fixation treatment and follow-up,according to the patient′s X-ray performance,the incidence of neck shortening and influencing factors were sum up,and the results were statistical analyzed.Results 120 patients had been followed up,51 cases happened neck shortening,the fracture healing rate was 93.33%,Harris hip score was(79±16) points in neck shortening group,but in no neck shortening group was(85±24) points,difference had statistical significance between the two groups(P 0.05).The patient′s age,gender,bone mineral density value and the occurrence of neck shortening were obviously positive correlation between the neck shortening group and no neck shortening group.Conclusion Elderly patients femoral neck shortening the internal jugular fixed a high incidence,the patient′s age,gender,bone mineral density value are the impact factors,neck shortening has no effect on the patients with fracture healing.
