SUMMERIZING THE OUTCOMES RELATED TO POSTOPERATIVE MANAGEMENT OF AVASCULAR NECROSIS WITH TOTAL HIP REPLACEMENT IN A TERTIARY CARE HOSPITAL

Abstract

Background: 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.
