Abstract
This implant comprises a portion (1) intended for anchorage to bone and a body (2) for attachment to a rod (3); the body has a channel defining two side branches (4) and open on both sides of the body in order to be able to receive the rod (3); this implant contains a threaded plug (8), contrived so that it can be screwed into a female thread formed in the inner walls of the two branches (4) so that its two diametrically opposed edges bear on the rod (3), and the face of the plug (8) directed towards the rod (3) is equipped with means of gripping and attaching the plug to the latter, which can thus be clamped in translation and rotation. This arrangement considerably decreases the external bulkiness of the implant, and reduces the number of parts necessary, as well as the corresponding instrumentation.
