Abstract

See full text

A closure system for an osteosynthesis apparatus includes an implant, such as a bone screw, a cap and a set screw which in combination is adapted for securement of a spinal rod or the like thereto. The implant includes a head having a rod receiving channel and tongue receiving grooves extending into opposed branches on opposite sides of the rod receiving channel. The cap includes a central portion with a set screw receiving bore extending therethrough and opposed tongues extending outward therefrom on opposite sides thereof. The cap is sized for insertion on the implant head such that the central portion extends through the U-shaped rod receiving channel and the tongues extend through the tongue receiving grooves. The cap includes a cylindrical rod receiving groove formed in a bottom thereof between the opposed tongues which is rounded upward at a front end thereof. Leading edges of the tongues are rounded downward and rearward to a flat bottom surface of the tongues. Front stops extend upward from the front of the tongues and rear stops extend upward from the rear of the tongues. The front and rear stops engage opposed faces of the implant head upon raising of the cap after insertion through downward advancement of the set screw through the set screw receiving bore and against a spinal rod.
