Systems and methods for fixation of adjacent vertebrae

摘要: A method for internal fixation of vertebra the spine to facilitate graft fusion includes steps excising nucleus an affected disc, preparing a bone graft, instrumenting vertebrae fixation, and introducing into resected nuclear space. Disc resection is conducted through two portals annulus, with one portal supporting instruments other viewing device. The hardware inserted small incisions aligned each pedicle be instrumented. screws, plates, engagement nuts, linking members. In important aspect method, nuts members are supported suprafascially but subcutaneously so that fascia muscle tissue not damaged. screw configured support above fascia. further invention, three component dilator system provided use during implantation method.
