A study is presented of the radiographs of 68 patients with unilateral Perthe's diseasemtwo types of Perthe's disease are identified: 'fragmenting' and 'non-fragmenting'. The two radiological types of the disease showed no significant differences in the age at diagnosis, the duration of symptoms before diagnosis and the duration of the disease. However, the radiologically-measureable results at healing, in terms of the epiphyseal, acetabular, acetabulum-head and comprehensive quotients were all very significantly worse when fragmentation had developed.
一项针对68例单侧佩特兹病患者X线片的研究表明，可识别出两种类型的佩特兹病：“碎裂型”和“非碎裂型”。这两种放射学类型的疾病在诊断年龄、诊断前症状持续时间和疾病持续时间方面均无显著差异。然而，就骨骺、髋臼、髋臼-股骨头和综合商数而言，愈合时放射学可测量的结果在出现碎裂时均显著更差。
