Clinical and Functional Outcome of Cemented Total Hip Replacement in Osteonecrosis of Head of Femur

ABSTRACT

Background: Osteonecrosis of the femoral head is one of the common causes of painful hip in more than 50yrs of age. At this age is associated with high functional demand. Osteonecrosis may have a devastating effect on the quality of life. The natural course of this disease is one of relentless progression with eventual collapse of the femoral head followed by secondary osteoarthritic changes in the hip. The management depends upon many factors including severity and location of necrotic lesion, patient factors and probability of collapse. Total hip replacement (THR) is needed in cases of collapse of femoral head, severe pain, osteoarthritis or destruction of hip joint. Moreover the factors like functional outcome after surgery implant longevity and need for revision surgeries must be considered while doing cemented total hip arthroplasty. In this context we conducted this prospective observational study to find out the clinical and functional outcomes of cemented THR in patients with of osteonecrosis of femoral head. Methods: The treatment period were january 2017 to june 2018 and sample size 20.we did our cemented total hip replacement through posterior approach (moore ) of hip and follow up was done at 4 ,6, 8 weeks and thereafter every 3 months. pre and post operative radiological and functional outcome has been compared. Results: In this study 18 patients (90%) had excellent results while 1 (5%) had good functional outcome and 1(5%) had poor outcome after cemented total hip replacement in osteonecrosis of femoral head. Conclusion: The mean HHS and number of patients with good to excellent result in our study..
