COMPARISON OF FUNCTIONAL OUTCOMES BETWEEN UNCEMENTED UNIPOLAR AND CEMENTED BIPOLAR HEMIARTHROPLASTY FOR INTRACAPSULAR NECK FEMUR FRACTURES IN ELDERLY

Abstract

Background: Femoral neck fractures (FNF) are a growing problem in our ageing society and have been associated with high morbidity and mortality. Hemiarthroplasty is the most commonly used treatment for displaced femoral neck fractures in the elderly. There is limited evidence in the literature of functional outcome with cemented implants compared to AMP in aged more than 70 years. Hence an attempt is made to compare the outcome with unipolar vs cemented bipolar prosthesis for displaced fracture neck of femur in patients aged more than 70years. Ours is a prospective comparative st Materials And Method: udy conducted, involving 40 patients with short term follow up of one year. Elderly patients above 70 years of age, with displaced fracture neck of femur were included. 20 patients were operated with Austin Moore Prosthesis (AMP) and 20 with bipolar prosthesis. The functional hip score was assessed using Harris Hip Score (HHS). The statistical software SPSS 15.0 (Statistical Package for Social Sciences) was used for the analysis of our data. In our study, Result: mean duration of surgery in uncemented group was 70 minutes and mean duration of surgery in cemented group was 82 minutes. On the basis of HHS the results were at 6 weeks follow up we had 70.2 for uncemented group and 77.5 for cemented group and in the last follow up at 6 months, we found HHS 84.2 for uncemented group and 85.6 for cemented group. There were 3 complications in cemented as a cement reaction and 2 supercial infection one in cemented and other in uncemented group. Both cemented Conclusion: and uncemented prostheses can be recommended according to our study because they were equally good regarding functional outcome and health-related quality of life, contrary to the generalized and limited published evidence. The seeming advantages of shorter duration of surgery and potentially less blood loss with the uncemented implant are of little importance compared with the important ndings of equivalent functional results. Both implants may be used with good results after displaced femoral neck fractures.
