SYSTEM AND METHOD FOR VERTEBRAL INTERBODY FUSION

摘要

<P>PROBLEM TO BE SOLVED: To provide a surgical inserter and a fusion cage system which provide for simplified fusion cage attachment and positioning. Ž<P>SOLUTION: The inserter 102 may comprise a collapsible collet with a locking rod. The fusion cage 100 with a rectangular cross-section head is secured to the inserter 102 through the reverse tapered aperture of the fusion cage 100. The collet can be lock the fusion cage 100 to the inserter allowing simplified manipulation of the collet with the inserter 102. The inserter 102 with the attached fusion cage 100 is inserted into a surgical patient. The fusion cage 100 is positioned within an intervertebral space. The locking rod is withdrawn from the collet allowing collapse and withdrawal of the collet from the fusion cage 100 leaving the fusion cage 100 positioned between two vertebrae and the inserter 102 withdrawn from the surgical patient.
