Filed:

Mar 6, 2000

Appl. No.:

09/519295

Inventors:

Hallett H. Mathews - Richmond VA

Assignee:

SDGI Holdings, Inc. - Wilmington DE

International Classification:

A61B 1758

US Classification:

606 61, 606191, 606104

Abstract:

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

International Classification:

A61B 17/58

US Classification:

606 90

Abstract:

An instrument for separating adjacent vertebrae includes a handle assembly and a distal portion at a distal end of the handle assembly. The distal portion includes first and second members movable from an unexpanded configuration for insertion in the disc space toward an expanded configuration to separate the vertebrae. A cutting member of a cutting instrument can be guided by the instrument to prepare the vertebrae for engagement with an implant.

International Classification:

A61F 2/44

US Classification:

623 1714, 606279

Abstract:

A prosthetic device for insertion into a spondylosed intervertebral space is provided. The prosthetic device includes a first component having a first flange for longitudinally engaging a first vertebra during longitudinal insertion therein, and a second component having a second flange for longitudinally engaging a second vertebra during longitudinal insertion therein. One of the first and second components comprises a projection and the other of the first and second components comprises a recess, the projection and recess being adapted to engage one another. One of the projection and the recess are offset relative to the other of the projection and the recess to accommodate the spondylosed relationship between the first and second vertebrae.
