摘要： An implant (310) for the spinal column is disclosed, comprising an elongated body having convex upper and lower surfaces (314, 317), a pair of lateral sidewalls (313, 315) and a cavity (332) opening at said upper and lower surfaces. The implant further comprises a leading end portion (316) structur ed for insertion into the disc space in a collapsed condition. An instrument (100) is disclosed for insertion of a spinal implant (110) having notches (124) in its lateral surfaces, the instrument comprising fingers (104, 108) to grip the implant in said notches, wherein the fingers do not protrude outwardly from the lateral suface (115, 113) of the implant both in the gripping and the non-gripping position.

摘要： Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

摘要： An artificial spinal (100) joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises an inferior arthroplasty half (104) . The inferior arthroplasty half comprises an inferior articulating component (112) for placement in an intervertebral dis c space between the superior and inferior vertebrae, a first posterior arm, an d a first bridge (116) component coupled between the inferior articulating component and the first posterior arm. The artificial spinal joint further includes a superior arthroplasty half (102). The superior arthroplasty half comprises a superior articulating component (106) for placement in an intervertebral disc space between the superior and inferior vertebrae, a second posterior am, and a second bridge (110) component coupled between the superior articulating component and the second posterior arm. The first posterior arm and the second posterior arm cross an anterior-posterior axis defined centrally through and extending from the intervertebral disc space.

摘要： A surgical method for preparing a site for implantation of a spinal implant into a disc space in which the disc space is first distracted by a novel stepped distractor, followed by insertion of a novel guide sleeve including a proximal portion having an uninterrupted side wall and a distal portion having a side wall defining a longitudinal opening extending along its entire length. The guide sleeve is seated adjacent the disc space with the longitudinal opening positioned opposite the dural region of the spine to provide a working channel to the disc space. A cutting tool is then inserted through the guide sleeve to remove tissue and bone laterally extending into the interior of the guide sleeve through the longitudinal opening, but only as much as necessary for passage of the spinal implant. In a further embodiment, a protective barrier, including a pair of overlapping, flexible leaf members, is operably attached to the inside surface of the guide sleeve and positioned across the longitudinal opening to separate the inner region of the guide sleeve from the outer surgical environment.

摘要： The invention includes a composite material for use in the construction of orthopedic devices and methods for using these composites. The composite material is comprised of at least one filament or cord that can be non- biodegradable and a biodegradable matrix. In other forms the composite material contains at least two components formed of a biodegradable material , which components can be a matrix or a filament or a combination of matrices and filaments. The degradation rate of the two components need not be the same. The composite material is used in the construction of orthopedic devic es such as bone plates, bone rods, spinal rods, and laminate sheets that change physical properties in vivo.

摘要： An expandable spinal implant including a body having a plurality of movable portions cooperating to define an outer cross section having first and second transverse dimensions and first and second substantially planar surfaces disposed generally opposite one another and adapted to engage adjacent vertebral bodies. An expansion member co-acts with the movable portions to expand the body along each of the first and second transverse dimensions.
