Method of percutaneous paracoccygeal pre-sacral stabilization of a failed artificial disc replacement

摘要

A procedure for stabilization in situ of a failed artificial disc replacement (ADR) using a pre-sacral paracoccygeal approach to an inter-vertebral disc space, such as the L5-S1 disc space for example, where a bore is created in the ADR using a drill, and then a fastener is inserted into the bore of the ADR and used to compress the endplates of the ADR. The fastener may have ends that prevent movement of the fastener once established in the ADR, and maintain the ADR in compression. Subsequent to the stabilization of the ADR, a spinal fusion operation can be performed with the stabilized ADR such that regenerative growth of bone can surround and form over the ADR without relative movement of the ADR to resist complete fusion and immobilization, and thus to improve the clinical results.
