Abstract: Posterior cervical fixation with various forms of instrumentation has been used for reconstruction in cases of traumatic disorders and degenerative or tumor-related dysfunction of the cervical spine. Recently, posterior plate and rod techniques using lateral mass screws or pedicle screws have been reported to show excellent fusion rates (Xu et al., 2010). Nevertheless, because such cervical spinal instrumentation requires screw anchorage, which may expose the vertebral artery or neural structures and cause neighboring lateral mass damage, they are not used by some surgeons (Mihara et al., 2001; Xu et al., 2010). A spinous process plate system, S-plate (Kisco Co., Ltd., Kobe, Japan), has been developed for short in situ fusions in selected patients. In this fixation procedure, the spinous processes are securely sandwiched between a pair of spiked plates, which are pressed together by tightening screws that extend through the plates (Neo et al., 2006). To our knowledge, only one report has described this cervical fixation technique, specifically as a salvage operation for failed anterior cervical fusion (Neo et al., 2006).
