Twenty adults (32 hips) with acetabular dysplasia were followed up for an average of 22 years to determine the natural history of the disorder. Initially, all hips had a center-edge (CE) angle of Wiberg of 20 degrees or less and an essentially intact Shenton's line with no roentgenographic evidence of osteoarthritis. Average patient age initially was 43 years (range, 27-57 years) and at final follow-up examination, 65 years. Various parameters of hip integrity were measured, including the CE angle of Wiberg, acetabular angle of Sharp, percentage of the femoral head covered by the acetabulum, acetabular depth, and inclination of the lateral lip of the acetabulum. None of these indicators proved a reliable prognostic aid for predicting the rate at which the osteoarthritis process supervened in any one case.
对20名患有髋臼发育不良的成年人（32个髋关节）进行了平均22年的随访，以确定该疾病的自然病程。最初，所有髋关节的Wiberg中心边缘（CE）角均为20度或更小，Shenton线基本完整，无骨关节炎的X线证据。患者初始平均年龄为43岁（范围27 - 57岁），最后一次随访检查时为65岁。测量了髋关节完整性的各种参数，包括Wiberg的CE角、Sharp髋臼角、髋臼覆盖股骨头的百分比、髋臼深度以及髋臼外侧唇的倾斜度。这些指标均未被证明是预测任何一例骨关节炎进程发生率的可靠预后辅助指标。
