Abstract
A side locking system is rotatable in all directions for use in a spinal surgery. Such a system comprises a side locking member, a spherical liner, and a fastening element. The side locking member is composed of a side locking block and a rotatable locking block. The side locking block has a through hole for receiving and holding a spinal locking rod and has a fastening slit substantially perpendicular to the axis of the through hole. The rotatable locking block has a rotatable receiving mount of spherical construction. The spherical liner is mounted in the rotatable locking block and provided with a hollow portion so dimensioned as to receive and hold a spinal pin. The fastening element is capable of tightening the fastening slit of the side locking block so as to bring about a compression of the spherical liner, which in turn causes the through hole of the side locking block to clamp the spinal locking rod.
