A linearly expanding spine cage has a minimized diameter in its unexpanded state that is equal to the diameter of an insertion groove cut into adjacent vertebral bodies. The cage conformably engages between the endplates of adjacent vertebrae to effectively distract the disc space, widen neuroforamina, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can be corrected, and natural curvatures maintained. The cage enhances spinal arthrodesis by creating a rigid spine segment. Expanding linearly (vertically, along the vertical axis of the adjacent spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage width remains stable, so as to decrease impingement upon a second cage, or upon soft tissue structures in the immediate vicinity, including neural or vascular elements.

Methods, systems, devices and tools for placing bone stabilization components in a patient are provided. The systems and devices have a reduced number of discrete components that allow placement through small incisions and tubes. More particularly, the present invention is directed to systems and methods of treating the spine, which eliminate pain and enable spinal motion, which effectively mimics that of a normally functioning spine. Methods are also provided for stabilizing the spine and for implanting the subject systems.

Methods and apparatus for forming one or more trans-sacral axial instrumentation / fusion (TASIF) axial bore through vertebral bodies in general alignment with a visualized, anterior or posterior axial instrumentation / fusion line (AAIFL or PAIFL) in a minimally invasive, low trauma, manner and providing a therapy to the spine employing the axial bore. Anterior or posterior starting positions aligned with the AAIFL or PAIFL are accessed through respective anterior and posterior tracts. Curved or relatively straight anterior and curved posterior TASIF axial bores are formed from the anterior and posterior starting positions. The therapies performed through the TASIF axial bores include discoscopy, full and partial discectomy, vertebroplasty, balloon-assisted vertebroplasty, drug delivery, electrical stimulation and various forms of spinal disc cavity augmentation, spinal disc replacement, fusion of spinal motion segments and implantation of radioactive seeds. Axial spinal implants and bone growth materials can be placed into single or multiple parallel or diverging TASIF axial bores to fuse two or more vertebrae, or distract or shock absorb two or more vertebrae.

A spinal fixation and fusion device that includes a housing with leading deep surface conforming to the posterior aspect of the intervertebral disk and trailing outer surface conforming to the anterior surface of the disk, weight bearing sides and the top and bottom surfaces with plurality of openings enabling ingrowths of bone. The device further includes a shaft running from the center of the deep surface and perpendicular to the deep surface of the housing to the center of the outer surface of the housing and affixed at least to the deep surface of the housing, and a flat metal member threaded onto the shaft with sharp leading edge which upon clockwise or counterclockwise rotation about the axis of the shaft will break the endplate, hook into the vertebra and rigidly secure the vertebra to the entire device preventing separation of the vertebra from the device during spinal motion.
