An implantable, modular spine stabilization system that allows for multi-level treatment of the spine by providing either rigid fixation or dynamic stabilization at different levels to be treated is provided. This modular spine stabilization system may be configured to span multiple spine levels, and have a curvature that closely matches the curvature of the spine over those multiple levels to be treated. Further, the modular spine stabilization system allows adjustment of the curvature of the overall system such that the system may be adapted for a patient for a customized fit. Instruments are also provided for the assembly and/or implantation of the modular spine stabilization system. The associated instruments may include instruments for adjusting the curvature of the system to the patient, and for implanting the curved system into the patient. The instruments may be configured for implantation of the system in a minimally invasive surgery.

The present invention involves a system and methods for nerve testing during anterior surgery, including but not limited to anterior total disc replacement surgery, nucleus replacement, and interbody fusion.

System and methods for monitoring during anterior surgery

A method and apparatus for customizing an intervertebral implant includes the initial step of obtaining a 3D anatomy of a series of vertebrae including an abnormal vertebra in a computer. The 3D anatomy of the series is then repositioned in the computer to eliminate the deformity caused by the abnormal vertebra. It is next determined whether a superior or inferior surface of the abnormal vertebra is an abnormal surface which causes the deformity, whereby an approximate gap between the abnormal surface and a desired normal surface is determined. Using that gap determination, a custom implant is constructed to engage the abnormal surface and fill the determined gap. Thus, when the implant is implanted between the abnormal surface and an adjacent surface of an adjacent vertebrae, the deformity is substantially compensated for. The implant may have articulation between the endplates to allow relative movement therebetween.

Customizing an intervertebral implant

An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The milling guide includes a longitudinal guide chamber which is tapered from a forward end to a rearward end. The system also includes a cutting tool which is received in the guide chamber in order to form a cutout in an adjacent vertebra. This cutting tool includes a bearing member which pivotally engages the rearward end to form a pivot axis for the cutting tool in the tapered guide chamber. Either the milling guide can be inverted to form the cutout in the other vertebra; or the milling guide can be provided with two guide chambers, to be used with one cutting tool moved between them or two respective cutting tools.
