Introduction: Fractures of neck femur in elderly have always been a challenge for Orthopaedic surgeons as it is associated with various medical comorbidities. By 2050 this number is suspected to be between 4.5 million – 6.3 million. A unipolar prosthesis is still extensively used in developing countries in low demanding patients. This study was undertaken to evaluate the functional and radiological outcome of geriatric patients treated with Austin Moore’s prosthesis.
Methods: Geriatric patients with femoral neck fractures, managed with hemiarthroplasty using Austin Moore’s prosthesis between January 2010 to March 2015 were included in this study. The data was extracted from the record room of our hospital. The patients were called up once and were analyzed clinically using the Harris hip score. Radiological the assessment was done on the Antero- Posterior & Lateral radiographs of the hip to look for seating of the collar of the prosthesis on the calcar, enlargement of the medullary anal, any degenerative changes over the acetabulum, varus pivoting, subsidence, osteolysis along the stem of prosthesis & lack of ossification in the fenestration hole of prosthesis.
Results: 112 patients fulfilled the inclusion and exclusion criteria and were included in the study, out of which 13 expired & 4 patients didn’t turn up for the follow-up. Remaining 95 patients were included in the study. Mean duration of follow up in our study was 5 .7 years (Range – 8.4 years to 3.6 years). 64.21% showed well while 3.16% showed poor Harris hip score. Radiologically 65 patients showed prosthesis collar seating over calcar while 11 patients showed acetabulum changes, 15 had enlarged medullary canal, 13 showed varus pivoting, 17 hips showed osteolysis along the stem of a prosthesis, subsidence was seen in 14 patients and 53 patients showed lack of ossification in the prosthesis fenestration hole.
Conclusion: Though the unipolar Austin Moore’s prosthesis faces criticism for causing degenerative arthritis of the hip, a year or two after surgery. Majority of patients showed excellent to good results. We concluded that the use of Austin Moore’s prosthesis is a good treatment of choice in the fractured neck of the femur for geriatric patients.
