The efficacy comparative analysis of cannulated screws for the treatment of femoral neck fractures in the elderly

Abstract

Obejective To observe the effect of internal fixation with cannulated screws in the treatment of patients over 65 years with femoral neck fractures. Methods Twenty five patients over 65 years met the inclusive and exclusive criteria from March 2012 to May 2017 were included in the observation group, and at the same time, 21 patients with femoral neck fractures under 65 years old were selected as the control group. Both groups were treated with closed reduction and cannulated screw fixation. The difference of clinical efficacy between the two groups was compared. Results In the observation group, 23 cases were followed up, 1 case occurred nonunion, 2 cases had avascular necrosis of the femoral head. 21 cases of the control group were followed up, 1 case had nonunion, 1 case had avascular necrosis of the femoral head, there was no significant difference between the two groups. The difference of Harris score has no statistically significant between the observation group(78±11) and control group (82±9) at 1 year postoperatively. Conclusions The treatment of cannulated femoral neck fractures with cannulated screws can still achieve the same therapeutic effect as femoral neck fractures in the lower age group.
