    摘要： An intervertebral prosthesis implantable within a disc space and disposed between upper and lower vertebral endplates is provided. The prosthesis comprises a plurality of prosthesis modules insertable into the disc space, wherein the modules have at least one set of complementarily-shaped and sized surfaces, and wherein at least one of the modules is expandable. The modules have surfaces configured to engage within the disc space in a manner such that the modules form an assembled prosthesis of a size substantially preventing it from being outwardly expelled from the disc space, and the modules have bearing surfaces slidably engageable with the endplates to permit articulation between upper and lower vertebral endplates. In one embodiment, the at least one expandable module of the intervertebral prosthesis expands by inflation. In another embodiment, the at least one expandable module expands by unfolding into its intended form.

    摘要： This invention relates to interconnection assemblies for use with spinal fixation systems to treat spinal defects. The interconnection assemblies can include various spinal rod connecting members and interconnecting elements to secure the spinal rod connecting members to each other in variable orientations and lengths. The interconnection assemblies can be adjusted to minimize interference with the spinal column, bony processes, and associated neural, muscular, and ligament components of the spine all the while exhibiting a low profile. The interconnecting elements and related components can be provided as a completely assembled unit that does not inadvertently become disassembled prior to or during implantation.

    摘要： An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having flexibly distinctive first and second sections relative to one another configured to modify the manner of movement at the spinal motion segment.

    摘要： A method of manufacturing a curved spinal rod is disclosed. The method includes heating PEEK; injecting the PEEK into an arcuate spinal rod mold; holding the injected PEEK in the mold until the PEEK substantially sets; and removing the injected PEEK from the mold. In another aspect, a spinal rod is disclosed. The spinal rod includes an arcuate main body having a first end portion, a second end portion, and a central portion. The central portion has a non-circular cross-section with a height greater than its width. The first and second end portions and the central portion of the arcuate main body are integrally formed of a polymer such as polyetheretherketone (PEEK). The spinal rod also includes a rounded end cap adapted to mate with at least one of the end portions. The end cap is radiopaque.

    摘要： A method of injection molding an orthopedic device comprising: injection molding a polymeric orthopedic device having a length along a longitudinal axis; and deliberately inducing, in the device, a material property change along the longitudinal axis by varying a molding parameter during the injection molding. The material property may be, for example, elastic modulus and/or density. The molding parameter varied during the injection molding may be a supply material pressure. The orthopedic device may be an elongated rod-shaped element, such as a spinal fixation rod, which may or may not have a substantially uniform cross-section, and may or may not have a metallic core. A corresponding apparatus is also described.
