Comparison of results of hemireplacement arthroplasty versus total hip arthroplasty for displaced fracture of neck of femur in active elderly patients: Study of 65 patients

Abstract

65 patients were enrolled for the study. Randomization was done between the Total Hip Arthroplasty and Hemiarthroplasty. 48 patients could be followed up for a minimum period of 6 months. Mean age was 59.19 years (55-70) with slight male preponderance (58.3%).23 patients each had a Dorr type B & C femora whereas 2 had a Dorr type A femur. Mini Mental State examination was done to rule out any cognitive impairment. 28 patients were treated with Hemireplacement Arthroplasty whereas 20 were treated with Total Hip Arthroplasty. Mean blood loss was 271ml for HRA group and 332.5 ml for THA Group. One patient in the THA group had a posterior dislocation as compared to none in the HRA group. One HRA patient developed Acetabular erosion. At 6 months mean Harris Hip score was 90.04 (HRA group) and 86 (THA group).
