The diagnosis of sickle cell osteonecrosis was made based on anamnestic, clinical and paraclinical arguments (radiological classification by Arlet and Ficat). Results:We included 31 cases of sickle cell osteonecrosis (0.6%), including 18 female (58.1%) and 13 male (41.9%), with a sex ratio of 0.72 (M/F).The mean age was 25.6 years (range 10 and 44).The hip was the seat of the most common osteonecrosis: left unilateral in 15 cases (48.4%), right unilateral in 12 cases (38.7%) and bilateral in 4 cases (12.9%), follow-up of the shoulder, the location of which was bilateral in 2 cases (6.4%).According to the Arlet and Ficat classification, osteonecrosis was stage III in 15 patients (47.4%), stage II in 14 patients (45.1%) and stage IV in 2 cases (6.4%).The treatment combined medical treatment in all patients and surgical treatment in 6 patients (19.3%). Conclusion:This work underlines that osteonecrosis is a serious and disabling complication of sickle cell anemia.Adequate management involves analgesics and NSAIDs in our context.
