The aim of this work is to create a classification of flatness, which takes into account the accompanying deformations in different parts of the foot; to study the mechanism of formation of flatbed, depending on the etiological causes of pathology.
Materials and methods. The analyzed data were obtained during the treatment of the 31 patients aged 4 to 18 years with I-III degrees of PPD which formed according to different etiological types. Clinical methods included determination of the position of the heel bone, pronation of the foot, removal or reduction of the anterior part, deformation of the fingers, state of the iliac arches, overloading, inclination of heel bone and degree of foot mobility (patent for utility model No. 132904 «Method of determining the degree of mobility of the foot», со-authors O.A. Danilov, O.V. Shulga, V.V. Gorelik).
Results. Regardless of the etiology of platypodia appearance, we can separate out combinational variants of foot deformation, the obligatory component of which is the flattening of the iliac arches. Depending on the localization of deformation in one or another foot department, in combination with iliac platypodia, the classification was created that distinguishes 8 types of.
Conclusions. The platypodia progression of different types is affected by the age of the patients, muscles tone, the state of the ligamentous apparatus, changes in the ratio of bones, body w eight and activity of patients. When choosing a method of treatment it is necessary to take into account not only the flattening of the medi al arch, but also the associa ted foot deformation in its various parts in accordance with the above mentioned classification.
The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of an participating institution. The informed consent of the patient was obtained for conducting the studies.
