<p>The invention relates to a poly-axial cervical system (1) used for treatment purposes in case of failure of spinal column to maintain the inter vertebra (2) relations in cervical zone and consisting of screw (3) forming infrastructure in providing stabilization, body (4) having movement capability, rod (5) making the poly-axial cervical system (1) a whole and set screw (6) providing fixation of the rod (5). The said extension part (4.4) prevents remaining of the rod (5) on or by the rod housing (4.2) during stabilization process and serves as bridge during location of the rod (5) into the rod housing (4.2) on the body (4) and thus the rods (5) are pulled into the rod housing (4.2) in a short time period and in a neat manner.</p> |
