The Study of Treatment Outcome after Fixation of Femoral Neck Fractures Using Different Cannu-lated Screws

Abstract：Objective To investigate the treatment effect of hip after fixation of femoral neck fractures using cannulated screws. Methods A prospective study of 87 elderly femoral neck fracture cases was February 2010 to January 2012. There were 87 elderly femoral neck fracture patients admitted and satisfied standards. The patients were divided into two groups. In A group of 45 patients,three cannulated screws were placed with across solid flame,and three cannulated screws were placed with triangle arrangement in B group of 42 patients. Survey and compare the medical records of patients with sex,age,ASA score, fracture type,comorbidities between two groups. Through the operation records and postoperative follow-up,we compared two groups of the operative time,bleed volume,X-ray exposure time,surgical methods,anesthesia,femoral neck shorting,and post operative recovery of hip function. Results By comparing the two groups in sex,age,ASA score,fracture type,comorbidities, operative time ,bleed volume ,X - ray exposure time ,surgical methods ,and anesthesia ,there was no significant difference( P >0. 05). But comparing femoral neck shorting and Harris scores,there was significant difference(P < 0. 05). The Harris score of triangle arrangement group were less than A group. There weere more femoral neck shorting in group A. Conclusion Using three cannulated screws placed with across solid flame treated the elderly femoral neck fracture is more effective than triangle arrangement group methods in Harris and femoral neck shorting.
