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 system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.

Rigidly guided implant placement

A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.

Rigidly guided implant placement with control assist

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

Intervertebral disc having translation

A force applying surgical system is provided for use to assist in the insertion and/or removal of a surgical tool or a device attached thereto from an orthopedic structure. This surgical system comprises a medical impacting device that mates with a surgical tool such that the impacting device can be manually reciprocated along an axis of the tool to forcefully impact the impacting device on a portion of the tool. The impacting device can generate a distally directed force for inserting the tool (and/or an attached device) into an orthopedic structure, or it can generate a proximally directed force to remove the tool (and/or attached device) from an orthopedic structure.

Medical impacting device and system

An implantable spinal graft includes a substantially annular body with opposed superior and inferior surfaces. At least a portion of the superior and inferior surfaces includes a plurality of bone-engaging protrusions. Both of the superior and inferior surfaces also include at least one region that is free of protrusions. Preferably, the protrusion-free regions are centrally disposed and are oriented so as to be parallel to or angled with respect to an anterior-posterior axis of the implant. The implant further includes a tip on the posterior that is formed by converging portion of the superior and inferior surfaces.
