Brachymetatarsia is a rare congenital deformity which occurs most commonly in the fourth metatarsal. Most common purpose of surgery is to make a normal metatarsal parabola for better external appearance as well as physiological load bearing under the metatarsal heads. Common surgical treatment for brachymetatarsia is lengthening of short metatarsal either by one-stage lengthening with intercalary bone graft or gradual lengthening by distraction osteogenesis. Sometimes shortening of long metatarsal is combined with lengthening of the short metatarsal. The function of the foot is diminished due to diverse complication accompanying lengthening of the metatarsal, therefore preoperative consultation about the functional result is essential.
