Long Term Results of Bipolar Hemiarthroplasty in Treatment of Fracture Neck Femur

Abstract

Femoral neck fractures are intracapsular fractures that occur in the proximal femur in the area beginning distal to articular surface of the femoral head and ending just proximal to the intertrochantric region. to evaluate the functional outcome of bipolar hemiarthroplasty in patients with intra capsular femoral neck fractures . and to determine the factors affecting the outcome and to see whether bipolar hemiarthroplasty meets desired end result or not; patient will be evaluated using Harris hip score and radiographic assessment. The present work was a retrospective study including twenty patients. These patients were be followed up for minimum five years postoperatively and traced to detect their actual hip function and performance. The early complicated patients would be excluded. The mean age of the patients was 73.4 years. The Harris hip score showed satisfactory results at the end of follow up three patients (15%) had hip scores from 100 to 91 (excellent). eight patients (45%) cases had hip scores90 to 81 (good). Two patients (10%) were rated 80 to 70. (fair), and seven patients (35%) were rated below 70(poor) . The mean Harris hip score at the end of follow up was71.0 (range from 25.0-to97.0) with SD 22.4. It was found that the greater motion at the inner bearing correlated with better clinical results. Therefore the amount of motion at the two interfaces appears dependent on a number of variables and still a topic of debate.
