Abstract:
A banana-shaped cage adapted for use as an intervertebral fusion cage, wherein the leading direction of the nose of the banana cage is substantially in-line with the angle of the inserter shaft that inserts the cage into the disc space. It has been found that insertion of this cage requires lower insertion forces than the conventional cage whose leading direction substantially follows the arc of the banana curve.
