Abstract
An expandable stabilizing cage includes a body having a fixed cage section, an expandable cage section, formed as a number of elongate blocks, and a relief between the fixed and expandable cage sections. An orifice, which through the expandable cage section decreases in diameter with increased distance along the central axis of the body away from the fixed cage section, is provided through the body. The expandable stabilizing cage also includes a wafer, which, when inserted into the orifice through the body, causes outward flaring of the elongate bars for fixing the expandable stabilizing cage securely in place in the intervertebral disc space between two adjacent vertebral bodies. Upper elongate blocks have substantially planar upper surfaces. Lower elongate blocks have substantially planar lower surfaces. The surfaces may be provided with surface irregularities for facilitating stable engagement with adjacent vertebral bodies, exemplary irregularities including denticles, dimples, scores, grooves or small protuberances.
