Polymetatarsia: transplant of supernumerary metatarsal on fifth metatarsal
Pisani P. C., Germano M.
In the English-language literature the term polymetatarsia is often wrongly replaced by the term polydactyly, thus creating confusion and often forcing us to extrapolate information regarding polymetatarsia indirectly. Associated with malformation syndromes, polymetartasia mostly presents as an isolated deformity. Here we analyze the literature and report classifications, preoperative investigations and the preoperative program relative to this pathology. We report two cases of hexametatarsia and describe the clinical and radiographic picture. The two cases were treated with the same technique: hemidiaphysectomy of the accessory metatarsal and of the Vth metatarsal and subsequent stable synthesis with minifragment screws. The uniqueness of this type of deformity and the inadequate number of studies present in the literature do not allow us to perform standard treatment and leaves the choice of technique to the experience of the surgeon. Over and above classification references, the aims that guide the surgeon's choice should be to protect articular congruence, restoring the metatarsal axis possibly through a reduction stage.
