Aims: The aim of the paper is evaluation of hip joint formation after Pertheñs disease treated conservatively as well as estimation of diagnostic value of self-elaborated trochanter-head (T-H) and radius of head (R-H) coefþcients, in relation to Heyman-Herdonñs and Klisicñs methods. Methods: Hip joint radiograms of 33 persons after Perthesñs disease were underestimated, mean 9,23 years after termination of treatment. Measurements performed accordingly to Heyman-Herdonñs and Klisicñs methods and T-H and R-H coefþcients were referred to sex, age of the patient at the moment of start of treatment, Catterall groups, Catterall risk factors and side of necrosis appearance. Results: Since lesser trochanter is left intact in course of the disease, it was assumed as point of reference for self-elaborated T-H and R-H coefþcients, which were measured in A-P and axial projection. Statistic analysis of rentgenmetric methods revealed positive correlation between T-H coefþcient and H-H method as well as between R-H coefþcient and Klisicñs method. Conclusions: Time consuming Heyman-Herdonñs and Klisicñs methods of estimation are burdened with high measuring error. Used self-elaborated coefþcients are easy to trace and calculate, and measurements are precise. Above coefþcients are repetitive irrespectively of patient age and multiplanar, hence allow for more precise estimation of hip joint deformities after the treatment than used up to present H-H and Klisicñs methods.
