A roentgenographic review was made of 109 patients with unilateral Legg-Perthes disease, all of whom had experienced onset of symptoms prior to their sixth birthday. Roentgenograms taken at the time of healing and at final follow-up were grouped according to Catterall classification and modified Mose rating. The parameters measured were epiphyseal index, center-edge angle, extrusion index, epiphyseal quotient, and center-edge quotient. Average age at final follow-up was 12 years. A change in Mose rating between assessments at healing and final follow-up occurred in 16% of patients, with most of them showing improvement, supporting the concept that femoral heads in young children have the capacity to remodel. However, 24% of patients with Catterall III and IV disease had a poor result at final follow-up. Despite early onset of Legg-Perthes disease, patients with involvement of greater than half the femoral head are at risk for poor roentgenographic result.
对109例单侧Legg-Perthes病患者进行了X线片回顾分析，所有患者均在6岁前出现症状。根据Catterall分类和改良Mose分级对愈合时和最终随访时拍摄的X线片进行分组。测量的参数包括骨骺指数、中心边缘角、挤压指数、骨骺商和中心边缘商。最终随访时的平均年龄为12岁。16%的患者在愈合评估和最终随访之间的Mose分级发生了变化，其中大多数显示改善，这支持了幼儿股骨头具有重塑能力的概念。然而，24%的Catterall III级和IV级疾病患者在最终随访时结果较差。尽管Legg-Perthes病发病早，但股骨头受累超过一半的患者X线片结果不佳的风险较高。
