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. Aim of work: Better management of steroid induced femoral head osteonecrosis.
Methods: Our study was performed on 18 patients at Orthopedic department, Zagazig University Hospitals from first of August 2020 to end of January 2021. All cases were treated by cementless THA. 8 males and 10 females with mean age of 36.39 years (range: 23-52). The etiology was femoral head osteonecrosis due to steroid intake for treating different diseases. Clinically, the indications of operation were intolerable pain and limitation of hip motion. Modified Harris Hip Score was used for clinical evaluation preoperatively, postoperatively and at follow up. Results: Regarding sex distribution, 55.6% were females. There was significant statistical 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, two patients(11.1%)suffered from dislocation. Conclusion: Six months follow up of cementless total hip arthroplasty are fairly encouraging. Combined with suitable indications, cementless implants ensure good clinical outcome with minimal complications and low rate of loosening and are recommended for hip replacement in relatively young patients.
