ABSTRACT:
This invention relates to segmental spinal instrumentation, specifically metal spinal hooks and rods used for the correction of spinal deformities such as idiopathic scoliosis. It includes an apparatus for use in retaining a longitudinally extending member in position relative to a spinal column. The apparatus is comprised of a body having an open ended recess which extends through the body and is open along one side to enable the longitudinally extending member, spinal rod, to be moved into the recess. The recess having a side opening, a first end opening formed in a first side of the body and intersecting the side opening, and a second end opening formed in a second side of the body opposite from the first side and intersecting the side opening to enable the longitudinally extending member to be moved into the recess through the side opening and to extend from the first and second sides of the body through the first and second end openings. The recess having an inner thread convolution to enable receipt of fastener. The body including first and second ridges disposed on opposite sides of said side opening to enable engaging of reduction instrument. A connector element extending from a side of said body opposite from the side opening and connectable with the spinal column to connect said body with the spinal column. An apparatus is used for reducing a longitudinal member into hook body recess, said apparatus comprising a handle which extends to hook shaped configurations which engage ridges on hook body allowing reduction of longitudinal member through lever action.
