Abstract: The present invention relates to an interspinous spacer (10, 10?, 10?, 10??, 10??, 10???) for implantation between adjacent spinous process (SP) to treat spinal stenosis. The interspinous spacer preferably includes a W-shaped or S-shaped leaf spring body member (21) for insertion between adjacent spinous processes and one or more wire straps (42) extending from the body to attach the spacer to the adjacent spinous processes. The wire straps are preferably sized and configured to extend from one side of the leaf spring, along one side of a spinous process, over or under the spinous process to the other side wherein the wire strap can be coupled to the leaf spring. Alternatively, the spacer may include one or more hooks (60) for engaging one or both of the adjacent spinous processes.

Abstract: An allogenic intervertebral implant for fusing vertebrae is disclosed. The implant is a piece of allogenic bone conforming in size and shape with a portion of an end plate of a vertebra. The implant has a wedge-shaped profile to restore disc height and the natural curvature of the spine. The top and bottom surfaces of the implant have a plurality of teeth to resist expulsion and provide initial stability. The implant according to the present invention provides initial stability need for fusion without stress shielding.

Abstract: An implant comprising two or more bone fragments that are combined to form a single unit. Cancellous bone or cortical bone is removed from a source and fashioned into bone components with desirable shapes and sizes. The bone components may be integrated to form implants for implantation in the body. Bone stock may be formed by combining sections of various bones of the body, and the bone stock may be further fashioned for use as implants with particular geometries.

Abstract: An occipitocervical fixation system includes a plate for securing to the occiput and at least one pre-bent rod. The plate includes holes for receiving bone fasteners, and at least one clamping assembly for retaining a portion of a rod. The clamping assembly is selectively pivotable and lockable in place to fix the position of the rod.

Abstract: The present invention relates to a bone fixation assembly for securing a fixation device, such as a bone plate, to bone. The assembly includes the fixation device, a bushing, a fastening screw, and a locking screw. The bushing is seated within a through hole in the fixation device and can rotate within the through hole and has a sidewall with a bore. The sidewall has at least one slot for allowing outward expansion of the sidewall against the through hole to thereby lock the bushing at a selected angle relative to the axis of the through hole. The fastening screw has a threaded shaft for insertion through the bore of the bushing and threads into bone to secure the bushing and fixation device to bone. The head of the fastening screw fits in the bushing and includes a radial wall and open end defining a recess. The radial side wall has at least one slit for allowing outward expansion of the radial wall thereby outwardly expanding the sidewall of the bushing.

Abstract: A bone fixation assembly for securing a fixation device such as a bone plate, to bone includes a fixation device including a through hole; a bushing having a sidewall with a bore and a slot; a fastening screw with a threaded shaft and a head including a recess; and a locking screw with a body capable of being threaded into the head of the fastening screw to expand its radial wall. In use, the bushing is seated within the through hole of the fixation device at a selected angle and the fastening screw is inserted through the bore of the bushing such that its head fits in the bushing and its shaft is threaded into bone. The locking screw may then be threaded into the head of the fastening screw to expand the radial wall of its head resulting in the locking of the fastening screw, and bushing at a selected orientation within the through hole.
