Assessment of Outcome of Patients with Avascular Necrosis of Femoral Head Treated with THR at a Tertiary Care Centre

Abstract

Background: Avascular necrosis (AVN) is defined as a cellular death of bone components due to interruption of blood supply. The present study conducted to assess outcome of patients with avascular necrosis of femoral head treated with Total Hip Replacement. Materials and methods: The study conducted to assess outcome of patients with avascular necrosis of femoral head treated with Total Hip Replacement. Sixty cases of advanced AVN of femoral heads treated surgically by total hip arthroplasty were the subject of this study. The Harris hip scoring system was used to evaluate each hip post-operatively. Rating of 90 to 100 points was considered excellent; 80 to 89 good; 70 to 79 fair and less than 70 poor. Results: In the present study sixty patients were included in which majority of patients were between 31-40 years (40%). Out of 60 patients, 36 were males and 24 were females. The patients with avascular necrosis of femoral head treated with Total Hip Replacement shows excellent results in 51 cases, good results in 4 cases, fair results in 3 cases and poor results in 2 cases. Of the 60 patients, 5% patients had limb length discrepancy, 5% patients had posterior dislocation and 3.33% patients had delayed wound healing. Conclusion:The present study concluded that the patients with avascular necrosis of femoral head treated with Total Hip Replacement shows excellent results in 51 cases, good results in 4 cases, fair results in 3 cases and poor results in 2 cases. Of the 60 patients, 5% patients had limb length discrepancy, 5% patients had posterior dislocation and 3.33% patients had delayed wound healing.
