摘要： Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. One instrument is a shim having a blade and a shaft having a first end connected with the blade. The blade is inserted into a distracted disc space to maintain distraction during subsequent procedures. Another instrument is a driver for driving the blade of the shim into the distracted disc space. Various methods contemplate the use of these instruments to maintain disc space distraction during disc space preparation for receiving an implant.

摘要： In one embodiment of the invention, an anterior fixation system includes a plate defining a plurality of screw holes, a number of screws and a number of locking assemblies for fixing the screws to the plate. The system includes two bone screws, a fixed angle screw and a variable angle screw. Either the fixed or variable angled screws may be implanted with a single plate, and either type of screw may be placed into any of the screw holes along the plate. An intermediate portion of the fixed angle screw is configured to reside within the cylindrical portion of any of the holes when the screw is fixed to the plate such that it is prevented from rotating or pivoting within the hole and is non-threaded. The several screw holes may be in various patterns. The invention further contemplates a locking assembly to lock one or more bone screws within a respective screw hole. In one embodiment, the locking assembly includes a washer overlapping one or more screw holes and a locking screw. In another embodiment, a locking washer includes cut-outs corresponding to the screw recesses, along with a notch and key configuration.

摘要： A transverse fixator assembly for spanning between a number of longitudinal members (11) situated adjacent a patient's vertebrae and methods for fixation of the spine which allow variation of the distance between two or more vertebrae. The assembly includes a number of connectors (15) configured to span the distance between and engage the longitudinal members. The connectors define a thru-hole (16) for engaging a bone bolt (30) which is engaged to a vertebra plus a number of spikes (17) projecting from the connector. A locking mechanism is configured to prevent the bolt from rotating relative to the connector when the nut is being tightened. One or more of the connectors may be a dynamic connector which is slidably engaged to the longitudinal members to vary the distance between the vertebrae for compression or distraction.

摘要： Implantable devices useful for creating bony fusion particularly in intervertebral spinal fusion. The device is formed of bone and has an at least partially demineralized portion between two rigid bone portions creating an area of flexibility. In one application, the area of flexibility may be used to move the device between a reduced size insertion configuration and an expanded implanted configuration. In another use, the area of flexibility may be useful to dampen shock applied to the implant. A method is also disclosed for making the implants and inserting the implants into an intervertebral disc space to promote interbody fusion.

摘要： The attachment consists of two cushions (2a, 2b) with their inner surfaces applied against the lateral faces of the spiny processes (6, 7) on two adjacent vertebrae (8, 9), to which they are attached by ligaments (5a, 5b, 5c, 5d). . The attachment consists of two cushions (2a, 2b) with their inner surfaces applied against the lateral faces of the spiny processes (6, 7) on two adjacent vertebrae (8, 9), to which they are attached by ligaments (5a, 5b, 5c, 5d). The cushions can be made from folded and stitched strips or whole blocks of material in an approximately hemispherical or hemi-ovoid shape, and can have inner surface projections that fit in the gap between the spiny processes. In variants of the design the cushions can be fixed in place by extra ligaments or a transverse pin passing through them.

摘要： The present invention relates to a device for use in percutaneous surgery. The device comprises an elongated cannula having an inner dimension and an outer dimension sized for percutaneous introduction into a patient. Said cannula has a distal working end and an opposite proximal end and defines a working channel between said ends, said working channel being sized to receive a tool therethrough. A viewing element is provided having a first end connectable to viewing apparatus and an opposite second end disposed adjacent said distal working end of said cannula. There is further provided a fixture supporting said viewing element adjacent said working channel with said second end disposed adjacent said working end of said cannula, and said working channel has an inner dimension substantially equal to the inner dimension of the cannula.

摘要： A hollow intervertebral spacer comprises an elongate body with an outer surface (506') and a longitudinal axis. A chamber (530') is formed through the body along a second axis perpendicular to the longitudinal axis. A pair of arms (520',521') face one another and form a mouth (525'). Also claimed are instruments for implanting the spacers and methods for making and using the spacers.

摘要： A spinal fixation assembly is provided that includes a bone engaging fastener and an elongated member, such as a spinal rod. The fixation assembly is a multi-axial assembly that permits fixation of the bone engaging fastener to the spinal rod at any of a continuous range of angles relative to the rod in three-dimensional space. The fixation assembly includes a receiver member having a bore therethrough, the walls of which are tapered near the bottom, and a channel communicating with the bore and having an upper opening at the top of the receiver member for insertion of a spinal rod. Also included are an outer wedge member and an inner wedge member, both of which have generally the shape of a washer and a bore therethrough. In each wedge member, the respective bore is not parallel to the central axis of the respective wedge member. Additionally, the outside surfaces of the wedge members may be tapered, and the respective bores may be tapered, so as to self-lock when seated and tightened. The bone engaging fastener fits within the bore of the inner wedge member, which in turn fits within the bore of the outer wedge member, which in turn fits within the tapered sides of the receiver member. When the desired position of the bone engaging fastener in three-dimensional space is attained, the components are seated to achieve a tight friction fit.
