Abstract

Background: Osteonecrosis of the femoral head (ONFH) is a disease which has the death of bone tissue due to a lack of blood supply on the femoral head. It often  affects  the  middle-aged people, aggravation over time leading to hip osteoarthritis and loss of hip function. The treatment depends on the stage of disease progression. Cementless total hip replacement is indicated for stages IIb, III, IV according to Ficat and Arlet classification. Objectives: 1/ Evaluation of the results of uncemented total hip replacement in ONFH patients. 2/ Comment on the factor affecting the results of uncemented total hip replacement. Materials and methods: The descriptive cross-sectional study combined with a vertical follow-up 82 patients were diagnosed with osteonecrosis of the femoral head stages IIb, III, IV according to Ficat and Arlet classification with the indication of surgery to replace cementless total hip joint at Dong Anh General Hospital from January 2019 to June 2022. Result: Mean age was 42,6±10,7 years old. 82,9% of the patients were males and 86,6% of the patients were less than or equal to 55 years old. There were 22 patients (26,8%) had the condition on both leg; 31patients (37,8%) had affected right legs and the rest 29 (35,5%) were left legs. Mean follow-up time was 29,9±6,1 months. The mean Harris hip score improved from 41,74 ± 10,25 points preoperatively to 97.67 ± 6.82 points at final follow-up. There were no major complications such as aseptic lossening or revision at latest follow up. 100% of the patients were satisfied with the procedure. Conclusion: Uncemented total hip replacement surgery improves the quality of treatments and haves good motor function restoration in ONFH patients. The surgical outcome was correlated to the history of diabetes and BMI.
