SUBTALAR IMPLANT FOR ARTHROEREISIS OF THE TALOCALCANEAL JOINT

摘要

A subtalar implant for arthroereisis of the talocalcaneal joint. The implant being intended to be inserted into the talocalcaneal joint via its lateral orifice and having an oblong shape that extends longitudinally along an axis of insertion of the implant. The implant includes: a head with the shape of a cone of revolution centred on the axis of insertion; an anchoring thread; and a rod having the shape of a cylinder of revolution. The rod has, on its surface, the anchoring thread and being intended to be inserted up to the axis of rotation of the talocalcaneal joint. The head has, on its radially outer surface, a retaining element for retaining the implant in rotation about the axis of insertion, the retaining element being exerting retention against a colonising tissue.
