ABSTRACT:
Disclosed are novel devices and methods for modular occipital/spinal fixation, general bone fixation, as well as skull fracture repair, wherein a novel orthopedic plate designed for unicortical engagement of the bone, particularly the occiput, is employed which exhibits greater stability and safety over conventional methods. Also disclosed is a novel method and device for posterior spinal fixation, preferably involving the use of a locking screw/plate assembly for posterior facet screw fixation of cervical and thoracic vertebrae. A novel locking screw and locking tool is further disclosed which may be used with the inventive orthopedic plate and spinal fixation devices as well as other orthopedic devices.
