Evaluation of the efficacy of Bipolar hip prosthesis and Austin Moore prosthesis in the management of Intracapsular Fracture neck of femur
Ghansham A. Pol, Abhishek Ranjan

Background: Fracture of the hip is a common injury. With increasing life expectancy worldwide, the number of elderly individuals is increasing, and it is estimated that the incidence of hip fracture will rise from 1.66 million in 1990 to 6.26 million by 2050. Many surgeons perform hemi-replacement arthroplasty as a primary procedure for the treatment of fracture neck of femur. The successful application of it is in the hands of various surgeons points to its continued usefulness as both Austin Moore & Bipolar hemiarthroplasty for treatment of elderly patient suffering from fracture neck of femur achieve high ambulatory ability and low revision rates. Aim of the study: To evaluate the efficacy of Bipolar hip prosthesis and Austin Moore prosthesis in the management of Intracapsular Fracture neck of femur where replacement of head and neck of femur offers the advantage of rapid return of joint function. Materials and methods: This is a hospital based prospective study with 30 patients evaluated for efficacy and functional outcome of Bipolar hip prosthesis and Austin Moore prosthesis in the management of Intracapsular Fracture neck of femur. The duration of study was for one year. The study was done at tertiary care center in Rajarshee Chhatrapati Shahu Maharaj Govt. Medical College & C.P.R Hospital, Kolhapur. Implants used were Bipolar Prosthesis and Austin Moore Prosthesis. Results: Majority of the patients (40%) were from the age group of 76-80 years followed by 33.3% from the age group of 71-75 years, 16.7% from the age group of 81-85 years and 10% from the age group of 86-90 years. The mean age of patients was 78.07 ± 4.91 years. 3 (10%) patients had painful hip while 2 (6.7%) patients each had periprosthetic fracture and superficial infection. 2 (6.7%) patients each had limb discrepancy >2cm and acetabular erosion while 1 (3.3%) patient each had deep wound infection and intra operative fracture. The mean VAS Score at post-op 6 weeks was 4.83±2.13 which decreased significantly to 2.53±0.63 at post-op 3 months, 2.03±0.41 at post-op 6 months and 1.33±0.48 at post-op 1 year. There was significant improvement in VAS Score during follow-up period as per Student t-test. Conclusion: Hemiarthroplasty with Austin Moore Prosthesis is safe and effective method of treatment for displaced fracture neck of femur in elderly. There was early post-operative full weight bearing mobilization with reduction in major complications. The end functional results also depend on the associated comorbidities and optimum post op rehabilitation.
