Twenty-eight cases of Perthes' disease were evaluated roentgenographically a minimum of 4 years after diagnosis (range, 4-17 years). The original roentgenograms were examined to see if a prognosis was possible of the final result on the basis of: (1) "head at risk" factors, or (2) Catterall's degree of epiphyseal involvement. Five "head at risk" factors more accurately predicted the course of Perthes' disease than Catterall's degree of epiphyseal involvement. The latter may change as the disease progresses. There is a definite decreasing incidence of a good radiological result with an increasing number of risk factors. The 5 risk factors are: Gage's sign; lateral subluxation; calcification lateral to the epiphysis; diffuse metaphyseal reaction and a transverse epiphyseal plate. The ability to predict the probable course of the disease and the final result should allow early institution of a more rational treatment program.
对28例佩特兹病患者在诊断后至少4年（范围4 - 17年）进行了X线评估。检查最初的X线片，以确定是否能够基于以下因素预测最终结果的预后：（1）“有风险的股骨头”因素，或（2）卡特拉尔骨骺受累程度。与卡特拉尔骨骺受累程度相比，5个“有风险的股骨头”因素能更准确地预测佩特兹病的病程。后者可能会随着疾病进展而改变。随着风险因素数量的增加，获得良好放射学结果的发生率明显降低。这5个风险因素为：盖奇征；外侧半脱位；骨骺外侧钙化；弥漫性干骺端反应和横向骨骺板。预测疾病可能病程和最终结果的能力应有助于早期制定更合理的治疗方案。
