FUNCTIONAL OUTCOME OF NECK OF FEMUR FRACTURES TREATED BY HEMIARTHROPLASTY WITH CEMENTED BIPOLAR PROSTHESIS-A RETROSPECTIVE COHORT STUDY

Introduction: Neck of femur fractures are prevalent among the elderly and contribute signicantly to fracture-related morbidity and mortality worldwide. The rising incidence of these fractures can be attributed to factors like osteoporosis, age-related vision impairment, reduced neuromuscular coordination, lifestyle changes, sedentary habits, and increased life expectancy. Controversy surrounds the treatment choice for displaced neck of femur fractures, but hemireplacement arthroplasty with a bipolar prosthesis is often considered the superior option for elderly patients. Objectives: The primary objective of this study was to assess the functional outcomes of neck of femur fractures treated with hemiarthroplasty using cemented bipolar prostheses. Secondary objectives included evaluating pain and mobility outcomes. Methods: We conducted a retrospective cohort study on 30 patients with neck of femur fractures treated with hemireplacement arthroplasty using cemented bipolar prostheses at our institutions from February 2019 to February 2021,with a minimum of 2 years post-surgery follow-up and results were analysed using Harris hip score. Statistical analysis was performed using SPSS software, employing descriptive statistics such as frequency, percentage, and mean. Results: Among the study population, 60% were females, and 40% were males. The left side was affected in 53.33% of patients, with slip and fall being the most common mode of injury (80%). A total of 53.33% of patients reported no pain, while 46.67% were ambulant without support. Of these, 20% were able to climb stairs without assistance, and 20% could manage stairs with support. No xed deformities, stem loosening, acetabular erosion, or protrusio acetabuli were observed. The Harris hip score indicated that 33.33% achieved excellent results, 36.67% had good outcomes, and 30% showed fair results in our study population. Conclusion: Hemiarthroplasty with bipolar prostheses offers early mobilization, effective pain relief, and an improved level of activity with minimal complications. Early mobilization can reduce the incidence of pressure sores, pneumonia, deep vein thrombosis, and other complications in the elderly population, making it an ideal treatment for neck of femur fractures in the elderly age group
