Brachymetatarsia is a shortening in length of a metatarsal exceeding 5mm. This congenital anomaly most often affecting women and the second metatarsal is associated with frequent aesthetic disorders leading patients to consult. The one-time lengthening technique is described for the management of brachymetatarsia with good functional results. However, the metatarsal elongation in one time is limited to 15 millimeters, to avoid complications.

No study has presented the consequences of hypocorrection, especially cosmetic. Our hypothesis is that undercorrection (Hypocorrection) is associated with a higher rate of cosmetic dissatisfaction.
