Acetabular erosion after hemiarthroplasty

Abstract

Background: Neck of femur fractures are one of the devastating injuries in the old age. Their incidence is on the rise causing immense stress on the society. One of the most commonly done procedure is bipolar hemiarthroplasty. In our study we have evaluated the acetabular erosion after hemiarthroplasty, in neck of femur fracture patients after a minimum period of 2 years and have tried to correlate it with activity level of the patient. The aim of the study were early detection of acetabular erosion; to assess the functional outcome after minimum of 2 years after hemiarthroplasty by modified UCLA score; to correlate the functional activity level and radiological acetabular erosion. Methods: This is a retrospective radiological and clinical study. The post hemiarthroplasty plain radiographs, showing AP view of hip joint taken in the Department of Radiodiagnosis, PSGIMS&R will be studied along with activity level assessment. By Convenient sampling method, all the patients undergone cemented bipolar hemiarthroplasty, for fracture neck of femur after minimum of 2 years were assessed both radiologically and clinically. Functional activity level was assessed by Modified UCLA scoring system. Results: By this study we suggest an easy and effective way of evaluating acetabular erosion and clinical activity. There is significant increase in acetabular erosion as the duration after surgery increases. Conclusions: By this study we suggest an easy and effective way of evaluating acetabular erosion and clinical activity. There is significant increase in acetabular erosion as the duration after surgery increases. The clinical activity is by and large not significantly altered as the erosion progress at mid-term follow up.
