Abstract
A spinal fixation implant system for correction and fixation of the human spine to facilitate an anatomically correct fusion. The spinal fixation system may include a connector, a spinal rod, a spinal fixation component, and a fastener. The spinal fixation component preferably includes a fixation device such as a hook or screw for securing the spinal rod to vertebrae of the thoracic or lumbar spine. The connector preferably includes a threaded end adapted to receive the fastener and a receiving end adapted to receive the spinal rod. The fixation component may include a body having a tapered cavity for engaging the receiving end of the connector. Tightening of the fastener preferably draws 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.
