Purpose of this work is to evaluate intraoperatively the anatomical modifications of the metatarsal head in the most common deseases of the first metatarsophalangeal joint: hallux abductus, hallux valgus abductus, hallux valgus. 209 metatarsal head were studied. In the results we considered the anatomical sesamoid ridge on the plantar surface, the crista flattening and its inversion (sulcus). In some cases we noted that the crista leaves its smooth ridge resulting in a longitudinal prominence sharpening reminding a boat “keel”. In 58 hallux abductus the head was flat in 29 cases (50%) with a medial wear in 14 cases (48.3%). In 98 hallux valgus abductus the head was flat in 64 cases (65.3%) with a central wear in 28 cases (43.7%) followed by a medial localization in 18 cases (28.1%). In 134 hallux valgus the articular surface was flat in 62 cases (46.2%) and the wear was medial or absent in 36 cases (58.1%). Considering the three pathologies we conclude that is frequent to observe a flattening of the first metatarsal head and the medial wear improves to the first toe angle augmentation.
