    摘要: A surgical instrument for assembling a spinal prosthesis to a plurality of anchoring members may be used to guide a driving tool and, if desired, to apply a distraction or compression force. The instrument includes two guide tubes with respective proximal, distal, and intermediate sections. The guide tubes are pivotally connected at their intermediate sections so that their respective longitudinal axes intersect and the cannulations of the guide tubes intersect. The surgical instrument may include a locking mechanism connecting the proximal portions and selectively operative to preserve an angular relationship between the guide tubes against at least one of increasing or decreasing.

    摘要: An intervertebral implant adapter for the L5-S1 juncture comprises a wedge shaped body of biocompatible material having upper and lower surfaces with the upper surface having a slot which provides slidable interlocking engagement with a motion or fusion implant. The lower surface is provided with any convenient bone anchoring mechanism. The adapter mates with an upper implant which is implanted after the adapter so as to provide an implant which matches the lordotic angle but which, in its multiple piece form, is no bigger than the posterior disk height.

    摘要: Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate (7) that has a generally triangular shape with an upper node (8a) and a pair of lower nodes (9a, 10a). The upper node (8a) has a hole (8) through the plate (7) to receive a screw (11) for passage into the L5 vertebra. The lower nodes (9a, 10a) each include a hole (9,10) through the plate (7) to receive screws (12, 13) for passage into the S1 vertebra. The system further includes a plate (7) having a retaining element (32) for preventing backout of screws inserted through the plate (9). Instruments and methods for attaching the plate to the spinal column are also provided.

    摘要: A screw placement guide includes a first member having a first guide adapted to contact a first vertebral bone portion and a second member having a second guide adapted to contact a second vertebral bone portion. A clamping mechanism provided on one of the members clamps the first guide and the second guide to the vertebral bone portions. The first guide and the second guide are aligned in order to indicate how a fastener will be aligned when fastened between adjacent vertebrae. A driver engages clamping mechanism to clamp the two members together.
