    摘要： Spinal prosthetic devices having selectable and/or changeable centers of rotation are disclosed. In one aspect, a spinal prosthesis kit includes a first component, a second component, and a plurality of inserts. The first component has a first articulating surface that includes a first articulating structure. The second component has a second articulating surface with a recessed opening adapted to receive one of the plurality of inserts. Each of the plurality of inserts includes a second articulating structure adapted to moveably mate with the first articulating structure. The second articulating structure is positioned in a different location on each of the plurality of inserts. In some embodiments, the articulating structures are moveably mating projections and recesses. In another aspect, a revisable prosthetic device having a first component, a second component, and an insert is provided.

    摘要： A system for removing an implant from between a pair of vertebral bodies comprises a removal shaft. The removal shaft includes a threaded shaft portion and is coupled to a spreader block. A connector body is threadedly coupled to the threaded shaft portion. The system further includes a first removal blade having a proximal end and a distal end. The proximal end is attached to the connector body and the distal end is attachable to the implant. A first spreader brace is attached to the spreader block. Rotation of the threaded shaft removes at least a portion of the implant from between the pair of vertebral bodies.

    摘要： A spacer for inserting between vertebral members. The spacer has a non-spherical shape with an anterior section having a first shape and a posterior section having a different shape. An attachment means is positioned within the posterior section, and may include a receiver for attachment with an insertion device, and an anti-rotation mechanism for assistance in removing the spacer from the insertion device. Embodiments of using the spacer is also disclosed which may include inserting the spacer between the vertebral members in a generally posterior approach. Once inserted, the insertion device acts with the anti-rotation device to remove a connection mechanism from the receiver. The spacer remains between the vertebral members and provides relief to the patient.

    摘要： A surgical tool and method are provided for positioning an intervertebral device between vertebral members. The tool includes an elongate shaft, an anti-rotation sleeve, and an actuation mechanism. The shaft has proximal and distal ends, with the distal end of the shaft including an engagement member for releasably engaging an intervertebral device. The sleeve includes proximal and distal ends, and is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The distal end of the sleeve includes an anti-rotation member. The actuation mechanism controls positioning of the sleeve between the retracted and extended positions, and locks the sleeve relative to the shaft. When the intervertebral device is releasably engaged by the engagement member, and the sleeve is in the extended position, the anti-rotation member engages the intervertebral device and prevents rotation of the intervertebral device when releasing the engagement member from the intervertebral device.
