EFFICACY OF CEMENTLESS TOTAL HIP ARTHROPLASTY IN STEROID INDUCED FEMORAL HEAD OSTEONECROSIS

Abstract

Background: Steroid-induced femoral head osteonecrosis in young adults has been a challenging disorder due to
femoral head collapse and resulting dysfunction of the hip joint. Total hip arthroplasty is a cost-effective procedure
that relieves pain and restores arthritic hip function. The aim of the present study to analyzed the outcomes of
cementless total hip arthroplasty in patients with femoral head osteonecrosis due to steroids.
Patients and Methods: Prospective study performed on 18 patients with steroid induced femoral head osteonecrosis
from January 2020 to January 2021. Cementless implants were used in all patients. 8 males and 10 females with mean
age of 36.39 years (range: 23-52). Modified Harris Hip Score was used for clinical evaluation preoperatively,
postoperatively and at follow up.
Results: There was a significant increase in modified Harris hip score among cases postoperatively compared to
preoperatively. Excellent results were in 1 hip (5.5%), good results in 12 hips (66.6%), fair in 4 hips (22.2%), and 1
hip (5.5%) had poor results. There were complications in 22.2% of patients, three patients (16.7%) suffered from
infection and two patients(11.1%)suffered from dislocation.
Conclusion: Cementless THA in young patients with steroid induced osteonecrosis is fairly encouraging. They ensure
good clinical outcome with minimal complications and low rate of loosening.
