Background. Static deformation of the forefoot is one of the common orthopedic pathologies, most often found in women. X-ray index of the first metatarsocuneiform joint (M1C1) is important during preoperative planning to determine the surgeon volume for surgical treatment of static forefoot deformity.Objective. To determine the radiometric prerequisites for the development of transverse platypodia depending on the structure of the first metatarsopharyngeal joint to improve the results of surgical treatment of patients.Material and Methods. From 2015 to 2017, a retrospective study of X-rays of 236 feet (118 patients) performed in a standard dorsoplant projection at rest and with a functional load was carried out.Results. The analysis of the obtained X-ray patterns revealed a direct dependence between the inclination of the articular surface of the medial sphenoid bone and angles of inclination of the articular surface of the base of the first phalanx of the first finger, the head of the first metatarsal bone (PASA), the intertarsal angle (M1M2) and the deflection angle of the first finger (M1P1).Conclusion. Further study of the dependence of the degree of transverse platypodia to the angle of inclination of the articular surface of the medial sphenoid bone and the use of the angle P1C1 as a prognostic indicator, in our opinion, will improve the quality of preoperative planning of surgical treatment of patients with transverse platypodia to reduce the risk of relapse.
