CALDINO-LOZADA, I; GALLEGOS-DE LA TORRE, O  y  ESPERON-HERNANDEZ, R. Case report: comprehensive treatment of forefoot with double brachymetatarsia in one surgical stage. Acta ortop. mex [online]. 2017, vol.31, n.2, pp.86-90. ISSN 2306-4102.

Brachymetatarsia (shortening of the metatarsal) directly affects the transversal arch of the foot causing severe deformities, such as hallux valgus, divergent toes, overlapping toes, metatarsalgia, all of these alter the biomechanics of the foot and gait. Treatment consists of two main techniques, one-stage lengthening with bone graft or elongation through callotaxis with external fixator; there are variants of both techniques used to minimize the disadvantages of each. The objective of treatment must be to return the structural harmony to the forefoot, improving the biomechanics, resulting in a satisfactory outcome for the patients. This article presents a surgical treatment for feet with closed physis to obtain the appropriate metatarsal formula and to reestablish aesthetics and function. This case was treated by means of one-stage lengthening with bone graft to the affected metatarsal; shortening of the adjacent metatarsals; hallux valgus alignment through the necessary osteotomies and the treatment of deformities of the lesser toes as needed. This surgical technique has as one of its advantages the correction of the entire forefoot at one time, without the need of an external fixator and its required postoperative care. Its main disadvantages are its dependence on structural bone graft and the need of postoperative dressing until healing of the bone has taken place. Satisfactory clinical and radiographical outcomes were obtained in treated patient.
