<p>A spinal fixation device and method including at least one longitudinal rod (32), a plurality of stem clamps (70a-70d) adjustably mounted to the longitudinal rod (32). A plurality of C-clamps (60) are provided and are mounted to the stems and to the longitudinal rods. Each C-clamp includes a female-tapered through passage (69) for matingly engaging a pedicle screw. A plurality of pedicle screws are used to anchor the C-clamps (60) to the bone and to the respective stem and longitudinal rod. The pedicle screws are configured with a recess (58) formed therein having threads therein for threaddly enaging a set screw (90). The pedicle screw includes a male-tapered head (55) for frictionally engaging the corresponding female-tapered through-hole (69) formed in the C-clamp (60) to form a morse taper locking fit. The C-clamp (60) also provides a clamping action for connecting the C-clamp (60) to the stems and the longitudinal rod.</p> |
