Prospective study in surgical management of femur neck fracture with hemiarthroplasty using modular bipolar prosthesis

Author(s): Dr. Sharanprasad AH, Dr. OB Pattanashetty and Dr. Ramanagouda Biradar
Abstract: Background: The frequency of Femur Neck fracture, one of the most common traumatic injuries in the elderly increases continuously due to the ageing of population on the planet [1]. It has been predicted that by 2050, the number of hip fractures would triple. Modular bipolar is an intermediate between the more type and total hip replacement, The primary goal of treatment of in the active elderly population is early restoration of premorbid walking ability and excellence of life
Materials and methods: A prospective, single blinded, randomized control trial with 33 cases, out of which 12 were males and 21 were females was conducted. The postoperative evaluation was done both clinically and radiologically. Out of the 33 cases, all patients were available for follow up till one year which was taken as a basic pre-requisite for inclusion in the study. At each follow up, patients were evaluated clinically using the Modified Harris Hip Score and radiologically with appropriate X-rays. Results: The modified harris hip score where by the end of one year there is 81.9% of good functional outcome. During study period 3 (9.7%) of the patients died due to medical conditions unrelated to surgical cause. the clinical outcome where in 27.2% had Excellent results, 45.5% had Good results and 12.1% had poor results. In our study we noticed that 4 of the patients were able to sit crossed leg and squat.
Conclusion: Hemiarthroplasty using Modular Bipolar prosthesis for fractures of the femoral neck provides freedom from pain, better range of movement and more rapid return to unassisted activity with an acceptable complication rate. The long term results using Modular bipolar prosthesis needs further study fora longer period in a larger sample with a direct comparison between the cemented versus uncemented groups. However, considering the good result achieved in the short term, it seems reasonable to use canal bone ratio in bipolar hemiarthroplasty as pre-operative template.
