Of 155 adults with sickle-cell anemia (SS, SC), radiographs of the pelvis or hip demonstrated protrusio acetabuli on at least one side in 14 (3 men and 11 women), as indicated by projection of the acetabular line medial to the ilio-ischial line by greater than or equal to 3 mm in men and greater than or equal to 6 mm in women. All 14 patients had bone changes attributable to sickle-cell anemia, including marrow hyperplasia and osteonecrosis; however, the severity of femoral or acetabular osteonecrosis did not appear directly related to the protrusion. The authors conclude that sickle-cell anemia can predispose to development of protrusio acetabuli.
在155例镰状细胞贫血（SS型、SC型）成人患者中，骨盆或髋关节X线片显示，至少一侧髋臼前突的有14例（3名男性和11名女性），男性髋臼线投影至髂耻线内侧大于或等于3毫米、女性大于或等于6毫米即提示髋臼前突。所有14例患者均有镰状细胞贫血所致的骨质改变，包括骨髓增生和骨坏死；然而，股骨或髋臼骨坏死的严重程度似乎与髋臼前突并无直接关联。作者得出结论，镰状细胞贫血可促使髋臼前突的发生。
