[Functional and radiological assessment of the hip joint after Perthes disease]

Basing a group of 33 patients treat conservatively because of Perthes disease some aspects of functional and radiological assessment of the hip joints is presented. Functional assessment was performed according to the authors' own scale. Radiological assessment was performed basing on Heyman-Herndon method, Klisica method and the authors' own head-trochanter factor and head radius assessment. A comparison of the obtained results was performed, and the clinical usefulness of the authors own head-trochanter and head radius was assessed. The head-trochanter factor correlated to the Heyman-Herndon method allowing assessment of the proximal epiphysis and physis of the femur, while the head radius factor correlated to the Klisica method and allows the assessment of head sphericity, head size and the degree of lateral subluxation of the head.
