摘要:
Methods and instrumentation for implantation of an intervertebral disc prosthesis are provided. A guide tool with sagittal and coronal reference features guides placement of guide pins relative to a sagittal plane and a coronal plane of the vertebrae. A retainer lockable to the guide pins has a ratcheting mechanism providing distraction or compression. A rasp, planer or other tools may be aligned to the retainer and inserted into the intervertebral space to prepare the vertebral endplates. An interoperatively adjustable trial is alignable to the retainer and measures an angularity of the intervertebral space. A prosthesis with keying features may be mounted to a prosthesis inserter with complementary features, held by pivotable arms and compressed between prongs. The inserter may be aligned to the retainer and advanced to implant the prosthesis in the intervertebral space. A prosthesis remover may grip one prosthetic end plate and extract the entire prosthesis.
