Abstract:Objective To investigate the characteristics of internal fixation with hollow screw and total hip arthroplasty on hip function recovery in elderly patients with femoral neck fracture. Methods A total of 130 elderly patients admitted in our hospital with femoral neck fracture from June 2013 to June 2015 were involved. Patients were randomly divided into group A in which patients received internal fixation with hollow screw, and group B in which patients received total hip arthroplasty. Postoperative recovery of hip function, Harris score, incidence of complications, reoperation rate, and costs of both groups were recorded. Results The operation time and intraoperative blood loss in group A were significantly decreased compared with group B (P < 0.05). The time to start first exercise, functional recoveryof hip, Harris score 3, 6, 12, 18 and 24 months after operation, incidence of re-operation in B group were significantly better than those in group A (P < 0.05). Costs for first operation were significantly higher while costs for second operation in group B were significantly lower compared with group A (P < 0.05). No significant difference in the incidence of postoperative complications and cost between 2 groups was identified (P > 0.05). Conclusion Total hip arthroplasty efficiently accelerates the functional recovery, reduces the risk of re-operation while does not increase the complications and costs in the treatment of elderly patients with femoral neck fracture. Still, internal fixation with hollow screw application is easier and decreases intraoperativeinjury.
