HEMIARTHROPLASTY OF INTRACAPSULAR FEMORAL NECK FRACTURE WITH AUSTIN MOORE PROSTHESIS

Abstract

Background: Hemiarthroplasty using Austin Moore Prosthesis of hip for femoral neck fractures is a good option in elderly, most of them obtaining a satisfactory outcome.

Objectives: The study was carried out to evaluate the immediate and early results of hemiarthroplasty for intracapsular fractures of neck of femur in elderly.

Methods: this was a prospective randomized trial performed on 52 old age patients who had femoral neck fracture. Hemiarthroplasty performed with Austin Moore Prosthesis and Harris hip score was used to evaluate the functional outcomes at 6 weeks, 3 months and 6 months follow up.

Results: We operated 65% of patients within first week 96% patients in first 10 days. Very few manageable complications with no operative death observed in our study. 33 patients had varying degree of limping which was slight to severe. 6 patients had positive radiographic results, 2 were having proximal migration and 4 patients showed loosening of prosthesis. Harris hip score was used to evaluate the functional outcome in the present study. Results were rated as – excellent: 90-100 in 27.08%; good: 80-89 in 45.83%; fair: 70-79 in 16.67% and poor: < 70 in 10.42% patients.

Conclusion: Operation procedure was simple and with less complicated. Early operation in old patients resulted in pain free, improved physical condition, mobility and lesser complications related to recumbence. Proper selection of cases, preoperative management, routine use of antibiotics and early mobilization minimizes mortality and morbidity. Functional grading excellent to good was seen in 72.91% patients which was a significant outcome.
