An intervertebral implant inserter, comprising:

Expandable trials

An expandable implant is made via a central strut having a pivotable arm on each end. The implant can be inserted into a disc space either horizontally or vertically with the arms in a closed position and then (if inserted horizontally) optionally rotated up into place. The arms are then pivoted out, thereby increasing the foot print of a horizontally inserted implant. The expanded implant can be locked in place through the use of an additional insert or ratchet that fits between the arms and locks the arms in place.

This invention relates to an intervertebral motion disc having two motion surfaces and. wherein the radius of the upper articulation surface of the core member is greater than the radius of the lower articulation surface of the core member, and wherein the first articulation surface of the core member is spherical and the second articulation surface of the core member is curved and non-spherical.

Intervertebral disc

A prosthetic is provided for replacing a vertebral disc. The prosthesis can comprise first and second endplates formed of a ceramic material, each including an articulating contact surface and a bone facing surface. The contact surface of the first endplate can have a shape complementary to the contact surface of the second endplate, thereby facilitating articulation of the first and second endplates while in contact with one another. The device can further include at least one non-ceramic bone attachment element mated with at least one of the bone facing surfaces, such that the bone attachment element covers less than a full area of the bone facing surface.

Ceramic disc prosthesis

This invention relates to an intervertebral motion disc having two motion surfaces and an open channel.

Intervertebral disc having translation

A medical instrument impacting tool that is useful for mating to a medical instrument used during spinal surgery is provided. The impacting tool is effective to apply a force to the medical instrument to efficiently and effectively prepare a bone structure, insert or remove a trial implant, insert or remove an implant, or to remove a medical instrument positioned between adjacent bone structures. In general, the medical instrument impacting tool includes a hollow tube, a handle slidably disposed around the tube, and a mass connected to the handle and slidably disposed within the tube.
