摘要： An osteotomy of a portion of a vertebral endplate and/or vertebral body allows for easier insertion of a device (502) that fits tightly into a disc space. A different aspect of the invention resides in a mechanical device (506) to hold the osteotomized portion of the vertebra against the vertebral body after the intradiscal device is placed. The device may be removed after the pieces of vertebra heal and fuse together.

摘要： Spinal alignment apparatus includes bodies which connect to vertebra to be aligned, and elongated elements that connect to the bodies. The elements are adjustable relative to the bodies in multiple dimensions, with locking mechanisms that allow the alignment to proceed in an orderly fashion until a desired degree of correction is achieved. Each elongated element has a shaped end terminating in the first portion of the lockable coupling mechanism. The vertebral connector bodies each include a feature for attaching the body to a respective vertebrae, and the second portion of the lockable coupling mechanism. The feature for attaching the body to a respective vertebrae may include a pedicle screw or, alternatively, a shape such as a hook adapted for sublaminar engagement. The elongated element also preferably includes a length adjustment mechanism, such as a telescoping or threaded section to provide a desired length in conjunction with a desired degree of alignment. Various coupling mechanisms are disclosed to provide multiple degrees of freedom prior to fixation.

摘要： Methods and apparatus for treating disc herniation provide a conformable device which assumes a first shape associated with insertion and a second shape or expanded shape to occlude the defect which typically follows partial dissection. The device may take different forms according to the invention, including patches (900) size to cover the defect or plugs (1002) adapted to fill the defect. In a preferred embodiment, however, the device is a gel or other liquid or semi-liquid which solidifies to occlude the defect from within the body of the disc itself. In another preferred embodiment, a mesh screen (202) is collapsed into an elongated form for the purposes of insertion, thereby minimizing the size of the requisite incision while avoiding delicate surrounding nerves. Such a configuration also permits the use of instrumentation to install the device, including, for example, a hollow tube (1206) or sheath adapted to hold the collapsed screen (1206), and a push rod (1204) to expel the collapsed device out of the sheath (1204) for use in occluding the disc defect. A device according to the invention may further include one or more anchors (902) to assist in permanently affixing the device with respect to the defect.

摘要： Existing bone dowels are improved through the use of rigid, preferably metallic end plates (306, 320). The plates are positioned relative to the anterior and posterior end surfaces of the bone dowel. The completed structure may be inserted, removed, and positioned into the vertebrae. The use of the rigid endplates (306, 320) facilitates load sharing which helps to prevent graft fracture. In the preferred embodiment, the end plates (306, 320) are positioned against the end surfaces of the bone section (400) through the use of a link member (308), which passes through the interior of the bone section (400) and connects the end plates (306, 320). One of the end plates (320) may include a threaded bore, and one end of the link member may be threaded to receive the threaded bore of that end plate to hold it in place.
