Management of fracture neck femur treated with bipolar hemiarthroplasty in the elderly population

Abstract

Background: Hip fractures are common and comprise about 20% of the operative workload of an orthopedic trauma unit. As life expectancy is increasing all over the world Geriatric population sustaining the Fracture neck of femur are also increasing resulting in Great burden to health of society which can be better managed with Hemiarthroplasty. The goal of the current study is to assess the functional outcome and quality of life in terms of pain, mobility, stability using Harris Hip Score Aims and objective of the study: To study the results of bipolar prosthesis with respect to pain, mobility and stability and to analyze the complications per-operative and post operative like infection, DVT, acetabular erosion, loosening and dislocation. Materials and methods: The prospective study included thirty patients with intracapsular femoral neck fractures referred to the Department of Orthopaedics, Ashwini Hospital, Gulbarga were selected for this study. Patients with intracapsular femoral neck fractures and aged above 55 years were considered. Discussion: We have excellent results in 10 cases (33.33%), good in 11cases (36.67%), fair in 7 cases (22.33%) and poor in two cases (6.67%) according to the Harris hip rating system. We got excellent to good results in 70% of the cases at a mean follow up period of six months. We analysed pain at 6 weeks, 3 months and 6 months follow up according to Visual analogue scale (VAS) in all patients. At 6 months follow up period, 70% patients had no pain (0), 20% had mild pain (1-4), 6.67% moderate pain (5-8) and 3.33% severe pain (>8). Early assisted ambulation was begun on second post operative day in our study, which probably accelerated better functional recovery. At 6 months follow up period, 70% patients were ambulatory without assistance, 23.33% patients were ambulatory with assistance (with cane). Conclusion: We came to a conclusion after treating 30 patients of intracapsular fracture neck of femur, with Bipolar prosthesis, that it has better advantage in terms of stability, mobility, range of motion, and functional outcome as per Harris hip score.
