摘要： A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller that the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of vertebrae to effectively distract the anterior disc space, stabilize the motion segments, eliminate pathologic spine motion, or effect vertebral body replacement. Angular deformities can be corrected, and natural curvatures restored and maintained. The cage enhances spinal arthrodesis by creating a rigid spine segment, or if filled with compressible substances, the cage can be used for motion preservation between vertebral bodies. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

摘要： A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. The cage enhances spinal arthrodesis by creating a rigid spine segment. Expanding selectively, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. Greater distraction height is achieved without an increase in implant size through the use of interfitted stages.

摘要： Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A bone anchor is described that includes an anchor body with expandable tines and a spreader that expands the tines into bone. Also disclosed is a bone anchor that includes a base and a top such that suture material may be attached to apertures in the anchor top or else compressed between surfaces on the base and top to secure the suture to the anchor. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.

摘要： The invention, in its preferred form, involves a pair of complementary substantially half-nut sections adapted to be manually assembled about a stud having a damaged thread to be repaired, the side walls of the half-nut sections being substantially arcuate to form a cylinder when assembled, to receive a socket adapted at one end to snugly slide over the assembled nut sections to retain them in their assembled positions. To preclude relative rotation between the socket and the assembled nut sections, one or both half-nut sections is provided with a planar slope intersecting the proximate arcuate outer surface, which planar slope is adapted to be engaged by a pin passing through the socket along a cord thereof, when the socket is slipped over the assembly nut sections. Upon application of pressure and a simultaneous turning force to the socket, either clockwise or counterclockwise in accordance with desired direction of travel, while being clamped against the same, in the course of which, the assembled nut-sections will repair the damaged thread or threads. The threads are preferably so designed as to essentially reform or mold the material of the damaged threads back into the original thread shape, as distinguished from cutting a new thread, as is the practice in the prior art.

Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

摘要： Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A bone anchor is described that comprises an anchor body with expandable tines and a spreader that expands the tines into bone. Also disclosed is a bone anchor that comprises a base and a top such that suture material may be attached to apertures in the anchor top or else compressed between surfaces on the base and top to secure the suture to the anchor. Also described is an inserter that can be used to insert the bone anchor into bone and move the spreader relative to the anchor body attach suture material. Also described is an inserter that can be used to insert the bone anchor into bone and move the anchor top relative to the anchor body or anchor base to attach to or clamp suture material there between. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.
