Abstract

Owing to the hampered blood supply, cellular death of bone components results in avascular necrosis of the femoral head. Aims: The present study was conducted to assess the outcomes following treatment of avascular necrosis of femoral head treated with Total Hip Replacement. Materials and methods: 54 subjects with advanced avascular necrosis of femoral head treated with Total Hip Replacement were included in the study. Each hip was postoperatively assessed using the Harris hip scoring system where scores less than 70 were considered poor, 70-79 as fair, 80-89 as good, and 90-100 as excellent scores. Results: In 87.03% (n=47) subjects Harris Hip scoring was excellent, in 7.40% (n=4) subjects, the scoring was good, in 5.55% (n=3) subjects Harris hip scoring was fair, whereas, in 3.70% (n=2) subjects, Harris Hip scoring criteria was poor. The postoperative complications were also assessed in the study subjects following total hip arthroplasty, and the results are shown in Table 3. It was seen that delayed wound healing was seen in 5.55% (n=3) study subjects, posterior dislocation was seen in 3.70% (n=2) study subjects, and limb length discrepancy was also seen in 3.70% (n=2) study subjects Conclusion: The present study concludes that subjects having advanced necrosis of femoral head managed with total hip replacement showed acceptable clinical and functional outcomes with a small incidence of delayed wound healing, posterior dislocation, and limb length discrepancy.
