Abstract

A surgical inserter and a fusion cage system which may provide for simplified fusion cage attachment and positioning. The inserter may comprise a collapsible collet with a locking rod. The fusion cage with a rectangular cross-section head may be secured to the inserter through the reverse tapered aperture of the fusion cage. The collet may be inserted into the reverse tapered aperture and the locking rod may control collapse of the collet. The collet may lock the fusion cage to the inserter allowing simplified manipulation of the collet with the inserter. The inserter with the attached fusion cage is inserted into a surgical patient. The fusion cage may be positioned within an intervertebral space. The locking rod may be withdrawn from the collet allowing collapse and withdrawal of the collet from the fusion cage leaving the fusion cage positioned between two vertebrae and the inserter withdrawn from the surgical patient.
