Our clinical results after core decompression surgery in patients with femur head avascular necrosis

A total of 27 patients who underwent core decompression surgery with avascular necrosis of the femoral head between 2015 and 2021 at Fırat University Faculty of Medicine Hospital were retrospectively analyzed. The mean age of the patients was 45.8 years. The most common reason in patients was found to be steroid use. The mean follow-up period of the patients was 36.1 months. The ficat arlet classification was used for radiological evaluation. Clinical evaluation was made according to Harris Hip score and Merle D'aubigne Postel Score. One of the patients was found to be preoperative stage 1, 29 of them were stage 2, and 5 of them were found to be stage 3. In the postop Ficat staging, 21 patients were stage 2, 10 patients were stage 3, and 4 patients were stage 4. The preop harris hip score of the patients was found to be the lowest 30 and the highest 76, with an average of 41.34, the postop harris hip score as the lowest 55, the highest 100, and the average 82.85. Preop Merle D'Augbine Postel Score was found to be preop lowest 5, highest 13 average 7.9, postop lowest 10 and highest 18 average 15. In this study, it was revealed radiologically that progress continued after core decompression surgery, but clinically obvious improvement was observed according to the harris and merle score.
