Vascularizacion del ligamento calcaneo-escafoideo

Abstract

The calcaneonavicular ligament or spring ligament is form by a complex of three branches, the superomedial calcaneonavicular ligament, the inferior calcaneonavicular ligament and the medial plantar oblique ligament. The superomedial ligament is the portion of the calcaneonavicular ligament that we can observe easier during the surgery and is the one who more frequently suffers some kind of injuries. The calcaneonavicula r ligament with others ligaments, in a passive way have the function of stabilis of the subastragaline articulation and the longitudinal internal arch of the foot. The injury of this ligament can produce the verticalization of the talus, this is clinically traduced in a plane medial longitudinal arch. The treatment of this lesion is the suture and retense. The objective of the study is to find the presence and the quality of the vascularity of the calcaneonavicular ligament , in that way we can make a prognoses if we make the direct suture itself. Thirteen ligaments were examinated, in those we evaluated the macro-micro vascularity and we made histologial studies of itself. The evidence anatomically and histologically that we made indicated a less vascularity in the central area of the superomedial branch of the calcaneonavicular Iigament.
