We have tested the reliability of a recently reported classification system of hip morphology in adolescents with cerebral palsy in whom the triradiate cartilage was closed. The classification is a six-grade ordinal scale, based on the measurement of the migration percentage and an assessment of Shenton's arch, deformity of the femoral head, acetabular deformity and pelvic obliquity. Four paediatric orthopaedic surgeons and four physiotherapists received training in the use of the classification which they applied to the assessment of 42 hip radiographs, read on two separate occasions. The inter- and intra-observer reliability was assessed using the intraclass correlation coefficient and found to be excellent, with it ranging from 0.88 to 0.94. The classification in our study was shown to be valid (based on migration percentage), and reliable. As a result we believe that it can now be used in studies describing the natural history of hip displacement in cerebral palsy, in outcome studies and in communication between clinicians.
我们测试了一种最近报道的针对闭合性三叶状软骨的青少年脑瘫患者髋关节形态分类系统的可靠性。该分类是一个六级有序量表，基于移位百分比的测量以及对Shenton弓、股骨头畸形、髋臼畸形和骨盆倾斜的评估。四名小儿骨科医生和四名物理治疗师接受了该分类使用的培训，他们将其应用于42张髋关节X光片的评估，并在两个不同时间进行阅片。使用组内相关系数评估观察者间和观察者内的可靠性，结果发现可靠性极佳，范围在0.88至0.94之间。我们研究中的分类被证明是有效的（基于移位百分比）且可靠的。因此，我们认为它现在可用于描述脑瘫患者髋关节移位自然史的研究、疗效研究以及临床医生之间的交流。
