UN DISPOSITIVO FIJADOR, EXTERNO Y DINAMICO, UTILIZABLE PARA EL TRATAMIENTO DE FRACTURAS DE HUESOS

摘要

A dynamic external fixator is disclosed which is designed to be applied externally along side the wrist by way of elongated bone fixation pins. The fixator includes two elongated legs connected by a universal joint. The proximal leg includes a series of holes for receipt of the bone fixation pins and associated threaded retainers to retain the bone fixation pins in the desired orientations. The distal leg includes a pistoning device which allows adjustability of the length thereof and further includes at least one set screw which reciprocates in a slot formed in the leg to enable the adjustment of the extension of the pistoning device thereof. The distal leg further includes a series of holes which receive the elongated bone fixation pins and further includes threaded members usable to maintain the bone fixation pins in a desired orientation. The universal joint includes means associated therewith which enables adjustment of the degree of movement of the proximal leg with respect to the distal leg and may also include means for indicating the degree of range of movement allowed in various adjusted positions thereof.
