ABSTRACT:
The present invention relates to a spinal hook body for use in a posterior spinal system including components designed to be affixed to the spinal column of a person to correct for various lateral and sagittal deformities. The hook body is adapted to interconnect a structure having a stud extending outwardly therefrom with an elongated rod. The hook body includes a recess with an opening at one side to receive the stud therein through the opening. The hook body further includes a bore in the body connected with the recess and adapted to receive the rod therethrough. A locking member is utilized for locking the hook body to the stud and rod. The spinal hook bodies are used in conjunction with the spinal system which also includes a pair of smooth surfaced rods mounted in spaced relation to one another on the spinal column in conjunction with various fixation devices such as clamps with the hook bodies, hooks, screws with the hook bodies and couplers. Each such fixation device utilizes locking sleeve assemblies at each connection point to secure the respective fixation device to the respective rod or rods. The coupler assemblies are provided to maintain the spacing of the rods. The method of performing surgery using the posterior spinal system is also disclosed.
