Pelvis radiographs of 30 children with slipped capital femoral epiphyses (SCFE) were reviewed by four readers to determine the skeletal age. The average chronologic age for girls was 12.1 +/- 1.0 years and that for boys was 14.4 +/- 1.3 years; the average pelvic bone age was 13.2 +/- 0.6 for girls and 15.1 +/- 0.6 years for boys. The chronologic age range was 98 months, and skeletal age range was only 50 months. Pelvis bone age was advanced in the youngest children, normal in most children, and mildly delayed in older children. We conclude that there is a uniform skeletal age or "narrow window" during which epiphyseal slipping occurs, regardless of the child's chronologic age.
四位阅片者对30例患有股骨头骨骺滑脱（SCFE）儿童的骨盆X光片进行了评估，以确定其骨骼年龄。女孩的平均实际年龄为12.1±1.0岁，男孩为14.4±1.3岁；女孩的平均骨盆骨龄为13.2±0.6岁，男孩为15.1±0.6岁。实际年龄范围为98个月，而骨骼年龄范围仅为50个月。骨盆骨龄在最小的儿童中提前，大多数儿童正常，年龄较大的儿童轻度延迟。我们得出结论，无论儿童的实际年龄如何，在骨骺滑脱发生时存在一个统一的骨骼年龄或“狭窄窗口”。
