    摘要: This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue.

    摘要: This invention provides a vertebral implant for impaction in a disc space to restore and/or maintain desired disc space height and spinal orientation. The implant has an elongated basis body having a generally lens-shape provided by convex upper and lower surfaces. Bearing surfaces are provided on the cross-edge surfaces of the endwalls. Grooves are provided in the upper and lower surfaces positioned between the bearing surfaces. The implant can be prepared from a wide variety of materials including metallic materials, synthetic materials, polymeric materials, ceramic materials, and composite materials including reinforced materials i.e. glass, fiber, and/or carbon fiber reinforced materials (CFRP). These preferred materials for fabricating implants in the present invention reduce costs, increase service life and provide excellent physiological compatibility. The non-metallic material can be selected to be either a substantially permanent material, a biodegradable material or a bioerodable material. Further, the implant material can be provided to be radio opaque to facilitate monitoring of bone ingrowth both into the implant and between the opposing endplates of the adjacent vertebrae.

    摘要: A percutaneous surgical system includes a plurality of tissue retractors configured to maintain a working space within soft tissue. The tissue retractors include a prong on their inner surfaces for engaging a ring member. The ring member maintains the position of the tissue retractors while also defining a number of channels inside the ring member. In one embodiment, the ring member includes concentric inner and outer walls connected by support walls. The inner wall defines an inner bore for supporting a working channel sleeve for the introduction of working instruments. A plurality of outer channels are defined between the inner, outer and support walls for the introduction of ancillary instruments to the surgical site. A manipulation tool is also provided that engages each tissue retractor for positioning the retractor within the patient.

    摘要: A guide sleeve with longitudinally offset bone engaging portions is provided for engagement with anterior-posterior offset vertebral bodies. In one aspect of the invention the guide tube has fixed bone engaging portions in a predetermined offset position. In another form of the invention, the guide sleeve is composed of at least two moveably connected portions adapted to permit adjustment of the offset between the bone engaging portions. Further, a method is provided for using a guide sleeve with offset bone engaging portions.

    摘要: A plate of biocompatible material is provided having curvature in two planes such that it conforms to the curvature of the L5 vertebral body and to the patient's lordotic curve. Holes are provided receiving screws for anchorage in the vertebral body and sacrum. A flange or foot portion on the plate provides a wider base end area for support in the L5-S1 interspace. The foot portion is also arranged for appropriate entry angle of screws into the sacrum such as to improve anchorage in the sacrum. Anti-backout and low profile features are incorporated. The anterior lumbar plate is situated to maintain the anterior interbody bone graft in compression by resisting tensile forces during extension.
