The constant relationship between forefoot and hindfoot as a basis for treating foot deformities

In correcting foot deformities the author observed a constant relationship between the forefoot and the hindfoot. If the forefoot is adducted, the heel automatically goes into the varus position. On the other hand, abduction of the forefoot will result in a valgus position of the heel. This rule was investigared and validified by experiments on cadavers: it was shown that the position of the hindfoot is automatically normalized by the correction of the forefoot. Our observations have been confirmed by treating foot deformities in children and adults. Therefore we believe that surgery of the talo-calcaneal joint in cases of foot deformity is unnecessary.
