One or more shaped axial bore extending from an accessed posterior or anterior target point are formed in the cephalad direction through vertebral bodies and intervening discs, if present, in general alignment with a visualized, trans-sacral axial instrumentation / fusion (TASIF) line in a minimally invasive, low trauma, manner. An anterior axial instrumentation / fusion line (AAIFL) or a posterior axial instrumentation / fusion line (PAIFL) that extends from the anterior or posterior target point, respectively, in the cephalad direction following the spinal curvature through one or more vertebral body is visualized by radiographic or fluoroscopic equipment. Preferably, curved anterior or posterior TASIF axial bores are formed in axial or parallel or diverging alignment with the visualized AAIFL or PAIFL, respectively, employing bore forming tools that can be manipulated from proximal portions thereof that are located outside the patient's body to adjust the curvature of the anterior or posterior TASIF axial bores as they are formed in the cephalad direction. Further bore enlarging tools are employed to enlarge one or more selected section of the anterior or posterior TASIF axial bore(s), e.g., the cephalad bore end or a disc space, so as to provide a recess therein that can be employed for various purposes, e.g., to provide anchoring surfaces for spinal implants inserted into the anterior or posterior TASIF axial bore(s).

This invention resides in an apparatus for inhibiting full extension between upper and lower vertebral bodies, thereby preventing pain and other complications associated with spinal movement. In the preferred embodiment, the invention provides a generally transverse member extending between the spinous processes and lamina of the upper and lower vertebral bodies, thereby inhibiting full extension. Various embodiments of the invention may limit spinal flexion, rotation and / or lateral bending while preventing spinal extension. In the preferred embodiment, the transverse member is fixed between two opposing points on the lower vertebral body using pedicle screws, and a cushioning sleeve is used as a protective cover. The transverse member may be a rod or cable, and the apparatus may be used with a partial or full artificial disc replacement. To control spinal flexion, rotation and / or lateral bending one or more links may be fastened to an adjacent vertebral body, also preferably using a pedicle screw. Preferably a pair of opposing links are used between the upper and lower vertebral bodies for such purposes.

Artificial disc replacement (ADR) components cooperate to limit axial rotation and / or lateral bending to a greater degree when the spine is extended than when the spine is a neutral to flexed position, thereby decreasing loads placed upon the facet joints. In the preferred embodiment, truncated articulating surfaces with non-articulating side surfaces allow increasing amounts of axial rotation and lateral bending as the total disc replacement (TDR) moves from full extension to full flexion. Limiting axial rotation and lateral bending of the TDR protects the facet joints and the Annulus Fibrosus, since the facet joints carry more load when the spine is extended than when the spine is flexed. Thus the invention serves to protect the facet joints while allowing normal or near-normal spinal motion.

A modular hydraulic spinal intervertebral prosthetic device offering individualized optimization of an implantable disc prosthesis by having selectable crown plates modules with differing lordosis angles and differing cross-sectional profiles, and selectable bellows cartridges having differing load-bearing capabilities. The device offers substantially full physiological degrees of motion, and by the incorporation of both a dashpot mechanism and a biasing element within reversibly displaceable and tiltable bellows provides hydraulic load bearing capability. The bellows assembly is advantageously pre-loaded to sub-atmospheric pressure. The dashpot further increases resistance to lateral sheer loading beyond the bellows convolutions acting alone. Rotational coupling of the upper crown plate and center bearings plate permits normal twisting movements, and spinal flexural freedom is provided by the bellows interposed between the center bearings plate and the lower end plate. The bellows also provides a hermetic seal which prevents any wear debris from migrating to the surrounding body tissue.

A spinal curvature correction device has a flexible tube having one or multiple lumens extending longitudinally through substantially the entire length of the flexible member. The lumens are a plurality of channels formed to receive multiple longitudinal members, or rods.

The hollow, flexible tube is surgically placed along the axis of the spine and fixed. After fixation to the spinal elements is structurally stable, a plurality of curved semi-rigid rods is placed within the channels of the flexible tube. As additional rods are placed within the hollow flexible member, increased force is applied to the spine by the device, thereby moving the spine towards the desired curvature.

A Posterior Dynamic Stabilization (PDS) device that regulates physiologic spinal elongation and compression. Regulation of elongation and compression are critical requirements of Posterior Dynamic Stabilization devices.

Duchenne muscular dystrophy (DMD) is a progressive muscle disease that is caused by severe defects in the dystrophin gene and results in the patient's death by the third decade. The present invention utilizes the Double Mutant mice (DM) as an appropriate human model for DMD as these mice are deficient for both dystrophin and utrophin (mdx / +, utrn − / −), die at 3 months of age and suffer from severe muscle weakness, pronounced growth retardation, kyphosis, weight loss, slack posture, and immobility. Expression from a transgene of novel human retinal dystrophin Dp260 was shown to prevent premature death and reduce the severe muscular dystrophy phenotype to a mild clinical myopathy. Electromyography, histology, radiography, magnetic resonance imaging, and behavior studies concluded that DM transgenic mice grew normally, had normal spinal curvature and mobility, and had reduced muscle pathology. EMG and histologic data from transgenic DM mice showed decreased abnormalities to levels typical of mild myopathy, while the DM mice exhibited severe abnormalities commonly seen in human dystrophinopathies. The transgenic DM mice also had measurable movement levels comparable to those of untreated mdx mice and controls.
