摘要： Devices and methods are disclosed for expanding a spinal canal. An implantable device having a shaft with a first cross-sectional dimension distinct from a second cross-sectional dimension can be inserted into an opening in a lamina and rotated 90 degrees to hinge the lamina away from the spinal canal. The implant can have one or more radiused edges, a bulleted tip, one or more lateral extensions for fastening the implantable device to bone, one or more hinged lateral extensions, one or more arcuate protrusions for biting into adjacent bone, an enlarged proximal head to prevent over-insertion, and/or a sleeve disposed therearound to reduce friction. Various embodiments of an insertion apparatus that can be selectively coupled to the implantable device are also disclosed, along with methods of expanding a spinal canal in minimally-invasive procedures using an implantable device and/or an insertion apparatus.

摘要： Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes a tensioning mechanism adapted to couple to a tether extending along a path between at least two bone anchors implanted in adjacent vertebrae. The tensioning mechanism can be adapted to apply a tensioning force to the tether along the path of the tether to thereby move the tether along the path. The device further includes an actuation mechanism movably coupled to the tensioning mechanism such that the actuation mechanism is adapted to effect movement of the tensioning mechanism to control the tensioning force applied to the tether.

摘要： A fiber-reinforced, polymeric implant material useful for tissue engineering, and method of making same are provided. The fibers are preferably aligned predominantly parallel to each other, but may also be aligned in a single plane. The implant material comprises a polymeric matrix, preferably a biodegradable matrix, having fibers substantially uniformly distributed therein. Inorganic particles may also be included in the implant material. In preferred embodiments, porous tissue scaffolds are provided which facilitate regeneration of load-bearing tissues such as articular cartilage and bone. Non-porous fiber-reinforced implant materials are also provided herein useful as permanent implants for load-bearing sites.

摘要： Spinal anchoring methods and devices are provided that are effective to correct spinal deformities while allowing some flexibility to the spine. In particular, the methods and devices allow a spinal fixation element to mate to several adjacent vertebrae to maintain the vertebrae at a fixed distance relative to one another, yet to allow the orientation of each vertebrae relative to the fixation element to adjust as the orientation of the patient's spine changes.
