Abstract

Introduction: Fractures of neck of femur are commonly seen in elderly people although all age groups can be affected, but increased predilection is seen in osteoporotic bones. The results of internal fixation are marked by a high incidence of nonunion and avascular necrosis. Several studies have found hemiarthroplasty to be better and more reliable than internal fixation in elderly patients. The  introduction of modular hemiarthroplasty whether unipolar or bipolar was an advancement because the neck length can be adjusted with regards to tension of abductors and leg length and further it can more easily be converted to Total Hip Replacement.

Aims and Objectives: Evaluation of functional outcome of uncemented modular bipolar hemiarthroplasty using Modified Harris Hip Score for fractures of femoral neck in elderly patients.

Material and Methods: The present study was a hospital based prospective study done on patients admitted in the Post Graduate Department of Orthopedics, Government Hospital for Bone and Joint Surgery, an associated hospital of Government Medical College, Srinagar. A total of fifty patients were taken up for the study.

Results: The mean age was 72.4 years (range 61 - 88 years). There were 20 (40%) male cases and 30 (60%) female cases (sex ratio = 1:1.5). Minor domestic trauma and fall was the cause of injury in 90% of the patients. The mean pre-operative score was 32.93, the maximum score being 65 and the minimum being 16. Postoperatively the mean total score was 88.967, with 76 being the minimum and 100 being the maximum.

Conclusion: Hemiarthroplasty using Modular Uncemented Bipolar prosthesis for fractures of the displaced femoral neck in elderly provides  pain relief, better range of movement and more rapid return to unassisted activity with an acceptable complication rate. Though conventionally done in a cemented fashion, uncemented modular hemiarthroplasty provides a good primary anchorage with equally promising results.
