摘要： A corpectomy device has an inner member telescopingly disposed in an outer member so that the inner member is movable in an axial direction. The inner and outer members are hollow, defining a chamber, and include apertures in communication with the chamber. A locking clip engages the inner and outer members to fix the position of the inner member with respect to the outer member. The longitudinal dimension of the device is adjustable by distracting the inner member so that the inner member extends from the outer member and moving the locking clip from an unlocked position to a locked position.

摘要： A dynamic subsidence plate is described having a first plate member and a second plate member in sliding engagement that may infinitely subside between a first and second assembled position. The plate includes a lock assembly associated with the first and second plate members. The lock assembly includes a ramp portion, an interference portion, and a bearing member situated between the ramp portion and the interference portion. The lock assembly of the plate is configured to allow movement of the first member with respect to the second member in a first direction in an infinite number of positions between a first assembled position and a second assembled position. Further, the lock assembly alternatively prevents movement of the first member with respect to the second member in an opposite second direction between the first and second assembled positions.

摘要： A method of inserting and positioning an intervertebral spacer is provided. The spacer includes a longitudinal axis, an on-axis interface coincident with or parallel to the longitudinal axis, and an off-axis interface angled to the longitudinal axis. The spacer's front end may be curved. The method may include inserting the spacer into the disc space utilizing a tool to engage an on-axis interface and then to engage one or more of the off-axis interfaces, which may be used for further modification of the spacer. The tool is moved substantially along a single insertion direction, which may be substantially parallel to a posterior-anterior axis of the disc space. The method may result in the longitudinal axis of the spacer being perpendicular to the insertion direction, or substantially parallel to a medial-lateral axis of the disc space. The spacer may also be positioned in an anterior aspect of the disc space.

摘要： A polyaxial screwdriver for inserting a bone screw in a vertebra. A polyaxial bone screw assembly includes a coupling element. When a screw engaging end of the polyaxial screwdriver is lowered on the head of the bone screw, the complimentary surfaces of the screw engaging end of the screwdriver and the head of the screw self-align. A ratchet mechanism formed in the screwdriver provides progressive and automatic locking of the polyaxial screwdriver to the coupling element and prevents the accidental unthreading from the coupling element. In another embodiment of the polyaxial screwdriver, a collet slides over the outside surface of the upper end of the coupling element and locks on to the coupling element. In yet another embodiment of a polyaxial screwdriver, the outer sleeve of the polyaxial screwdriver has a split end that securely engages the coupling element.

摘要： A spinal implant has a bone plate with a bone contacting surface and an opposite upwardly facing surface and at least one opening with a groove formed around an inner circumference of the opening. The groove has an axially spaced upper and lower surface. A bone-anchor or bone screw is capable of being accommodated in the opening between the groove and the bone contacting surface. A split-ring is mounted in the groove. The split-ring is sized to expand upon insertion of the anchor element into the opening and to come into direct contact with a head of the bone anchor to hold the bone anchor in the opening. The split-ring has an upper surface and a lower surface for respectively engaging the upper and lower surface of said groove, wherein the split-ring has a variable width so as to optimize its flexibility.
