Abstract
Fractures of neck femur is common fractures in elderly persons. It has always been a challenge for orthopaedic surgeons and it is associated with various medical co-morbidities. 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 treated with Austin Moore’s prosthesis.
Method: Geriatric patients with femoral neck fractures, managed with hemiarthroplasty using Austin Moore’s prosthesis between March 2019 to March 2021were included in this study. The patients were called up once and were analysed clinically using the Harris hip score. Radiological assessment was done on the Antero-Posterior& Lateral radiographs of the Hip to look for seating of collar of the prosthesis on the calcar, any degenerative change over the acetabulum, enlargement of the medullary canal, any degenerative change over the acetabulum, subsidence lack of ossification in the fenestration hole of prosthesis & osteolysis along the stem of prosthesis.
Results: 50 patients fulfilled the inclusion and exclusive criteria and were included in the study, out of which 7 expired and 3 patients didn’t turn up for the follow-up. Remaining 40 Patients were included in this study. Mean duration of follow-up in our study was 2yrs. 70% Showed good condition while 4% showed poor Harris hip score. Radiologically 24 Patients showed prosthesis collar seating over calcar while 5 patients showed acetabulum changes, 06 had enlarged medullary canal, 05 patients showed osteolysis along the stem of prosthesis and 20 patients showed lack of ossification in the prosthesis fenestration hole. Though the unipolar Austin’s Moore’s prosthesis faces criticism for causing degenerative arthritis of hip, a year or two year after surgery. Majority of patients showed excellent to good results.
