When placing the link around the blade of the vertebra and the connector has been achieved, the tension pulley handle is used to exert a tension on the link and thereby fix the anchor around the vertebra.The tension applied may be sometimes higher than the specified tension and lead to damaging the screw-nut system of the tension pulley handle, which causes jamming or blocking.In the latter case, the finalization of the tension of the link must be conducted by using another tension pulley handle.
