Fiches A4 R-V situ clinik 2P HALLUX VALGUS Document produced by the TALUS group of GECO (www.geco-medical.org) - 2004. The analysis of articular angles and congruence helps to precisely describe particular clinical situations, which require appropriate management. 1: DM2AA = 0 MODERATE CONGENITAL HALLUX VALGUS CLINICAL SITUATIONS CLINICAL SITUATIONS POUR UNE GESTION FACILE AU BLOC OPERATOIRE > Metatarsus varus and positive DMAA (DMAA > 7°), > Moderate angle M1- M2, > In most cases, the joint is congruent. Correction consists of simple translation of the head. 2: DM2AA IS POSITIVE SEVERE CONGENITAL HALLUX VALGUS > The DMAA is clearly positive, > The joint is congruent in most cases, Correction consists of varisation (medial derotation) of the head combined with translation.

> With or without abnormal DMAA, > This is the situation of metatarsus varus (angle M1-M2 > 16° > Articular incongruence is present. Correction consists of lateral translation or valgisation of the head (lateral derotation) and in most cases shortening of the first metatarsophalangeal ray. > Requires correction independently of the preceding clinical situations, > Phalangeal osteotomy enables correction of: interphalangeal valgus, Example of an Egyptian foot type with interphalangeal
