PROBLEM TO BE SOLVED: To provide a spinal fixation transplantation system for correction and fixation of the human spine to facilitate an anatomically correct fusion. SOLUTION: The spinal fixation system 10 may include a fixation device such as spinal hooks 22 and 24 or a bone screw 14 for securing the spinal rod 12 to corpus vertebrae such as vertebrae of the thoracic or lumbar spine. The spinal fixation component includes a threaded end on its top that is adapted to receive a fastener 18. The fixation component may include a body having a tapered cavity for engaging the fastening end of a connector 16. Tightening of the fastener preferably downward moves a sleeve over the fixation component body to force the connector through the tapered cavity, which compresses the receiving end about the spinal rod to fixably connect the spinal rod and the spinal fixation component. In an alternate embodiment, assembly pliers may be used to move the connector into the tapered cavity. The fixation component may also include a rotatable fixation member.
