Of 899 patients with sickle-cell disease, aged between 6 and 28 years, who attended clinics in the Guinea Savannah of Nigeria in 1982 and 1983, 29 had symptoms of avascular necrosis of the femoral head. This group was studied in detail. Twenty-eight patients had haemoglobin-SS electrophoretic patterns and one had haemoglobin-SC. The male to female ratio was 1 to 1.6, and most of the patients were aged between 6 and 15 years at the onset of hip symptoms. These symptoms correlated with the radiographic lesions, but were not related to the age or sex of the patient. The radiographic lesions varied widely and were related to the age at onset of hip symptoms. A new radiological classification is proposed.
1982年和1983年期间，在尼日利亚几内亚草原地区诊所就诊的899例6至28岁镰状细胞病患者中，29例有股骨头缺血性坏死症状。对这组患者进行了详细研究。28例患者血红蛋白电泳呈SS型，1例呈SC型。男女比例为1比1.6，大多数患者髋关节症状出现时年龄在6至15岁之间。这些症状与影像学病变相关，但与患者的年龄和性别无关。影像学病变差异很大，且与髋关节症状出现时的年龄有关。本文提出了一种新的放射学分类方法。
