Radiographs of the hips of 69 patients with cerebral palsy were evaluated for the angle of Wiberg, acetabular angle, degree of subluxation, shape of the femoral head, and, when the appropriate studies had been performed, anteversion and neck-shaft angles. Abnormalities included various degrees of superior lateral subluxation or dislocation, dysplasia of the acetabulum associated with femoral head displacement, flattening of the medial and/or lateral portions of the femoral head, an increase in the anteversion angle, functional increase in the neck-shaft angle, and, in long-standing cases, secondary degenerative joint disease and pseudoarticulation. Neuromuscular imbalances and abnormal ambulation caused by cerebral palsy change the biomechanical forces on the hip and result in characteristic osseous changes. Recognition and proper treatment of these changes can significantly alter the clinical course of the disease.
对69例脑瘫患者的髋部X光片进行了评估，测量了Wiberg角、髋臼角、半脱位程度、股骨头形状，并在进行了适当研究时测量了前倾角和颈干角。异常情况包括不同程度的上外侧半脱位或脱位、与股骨头移位相关的髋臼发育不良、股骨头内侧和/或外侧部分扁平、前倾角增加、颈干角功能性增加，以及在长期病例中出现的继发性退行性关节病和假关节形成。脑瘫导致的神经肌肉失衡和异常行走改变了髋关节上的生物力学力，导致特征性的骨质变化。认识并正确治疗这些变化可显著改变疾病的临床进程。
