Classification of Hallux Valgus Using Conjugated Deformity

Hallux valgus is a complex deformity of the forefoot. It result multiple effects endogenous and exogenous etiological factors with different degrees influence. The degree hallux was assessed by radiological values (HVA) intermetatarsal (IMA) angle. Thus, each corresponds to pair (HVA, IMA) angle in plane deformity. intensity point position vector S deformation determined relation represents absolute (conjugate) value power deformities. goal article explain advantage definition using its value, then show that defined this way enables better classification deformities for all HVA IMA angles. Furthermore, article, applying conjugate deformity, analytical expressions were constructed assessment average correction after operative treatment, as well error treatment. All obtained results checked on sample 396 operatively treated feet.
