Filed:

Mar 12, 2001

Appl. No.:

09/804277

Inventors:

Stanley Gertzbein - Houston TX
Michael C. Sherman - Memphis TN

Assignee:

SDGI Holdings, Inc. - Wilmington DE

International Classification:

A61B 1770

US Classification:

606 61, 606 73

Abstract:

A transverse fixator assembly for spanning between a number of longitudinal members situated adjacent a patients vertebrae and methods for fixation of the spine which allow variation of the distance between two or more vertebrae. The assembly includes a number of connectors configured to span the distance between and engage the longitudinal members. The connectors define a thru-hole for engaging a bone bolt which is engaged to a vertebra plus a number of spikes projecting from the connector. A locking mechanism is configured to prevent the bolt from rotating relative to the connector when the nut is being tightened. One or more of the connectors may be a dynamic connector which is slidably engaged to the longitudinal members to vary the distance between the vertebrae for compression or distraction.
