ABSTRACT:
The present invention relates to 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. A pair of smooth surfaced rods are mounted in spaced relation to one another on the spinal column in conjunction with various fixation devices such as clamps with hook bodies, hooks, screws with 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.
