Total Hip Replacement for Patients with Femoral Neck Fracture after Unsuccessful Primary Treatment

This cross-sectional study was carried out on 23 patients who underwent total hip arthroplasty(THA) following unsuccessful treatment of femoral neck fracture. The goal of the present study was to determine the results of THA as a therapeutic choice for patients with failed treatment of femoral neck fracture and to compare the results of THA in two groups of treated patients with two different techniques: internal fixation of fracture and hemiarthroplasty(HA). Therefore, patients were divided into two groups depending on the treatment they had originally received: those treated by hemiarthroplasty and those who were treated by internal fixation of fracture(IF). In both groups the pain and disability were compared before and after the operation and the results were compared across the two groups. The obtained results showed that pain and disability were remarkably reduced and Harris Hip Score(HHS) remarkably improved, especially in the second group(P<0.05). Complications like bleeding during the operation or dislocation after the operation were more numerous in group 2, but on the whole their incidence was at an acceptable level. It is believed that THA can be a suitable option in managing the patients in whom the treatment of the femoral neck fracture is failed.
