Evaluation of functional outcome of patients with fracture neck of femur treated with Austin Moore prosthesis at government medical college, Thrissur-a prospective study during October 2019 to October 2020

Background: Femoral neck fractures commonly affects the elderly population. 90% of femoral neck fractures in the elderly result from simple fall. Elderly age group suffers from innumerable illnesses such as diabetes, hypertension, coronary artery disease, chronic obstructive pulmonary disease, all of which can aggravate following a femoral neck fracture because patient can become completely bedridden. The aim of treating these patients is to make them mobilize as early as possible to achieve his or her pre-fracture functional status. The incidence of femoral neck fractures is increasing dramatically as the mean age of the population increases. Prosthetic replacement allows immediate weight bearing to elderly patients and thus helps to avoid complications of recumbency and inactivity. To study the functional outcome in patients with femoral neck fractures treated with Hemiarthroplasty using Austin Moore prosthesis.Methods: Prospective study was done among 42 consented patients who sustained neck of femur fractures and were admitted in department of orthopaedics, government medical college, Thrissur, between 01/10/19 to 01/10/20, who were aged above 60 years and presenting within 3 weeks of injury. Patients were followed up at an interval of 6 weeks, 3 months and 6 months functional outcome was analysed by modified Harris hip scoring system.Results:  Among the 42 subjects, 52.4 % were females and the rest were males. Mean age of the study population was 71.57±7.047 years. Harris hip score at end of 6 months ranged from 35 to 94. 33.3% of hemiarthroplasties had hip score of 91-100 (excellent), 38.1% of the hemiarthroplasties had scores of 81-90 (good), 19% had satisfactory/fair results whereas only 9.5% of hemiarthroplasties fell in poor category with scores below 70.Conclusions: Hemiarthroplasty with Austin Moore prosthesis is still a good option in elderly patients with femoral neck fractures
