Abstract
A porous intervertebral spacer comprises a plurality of strands of fused, tortuous wire of a biologically inert material, the porosity of the spacer being sufficient to facilitate tissue ingrowth and bony fusion. The spacer also can comprise a mixture of such strands and biologically inert beads. A method of fusing adjacent vertebrae of the spine includes the steps of excising a portion of an intervertebral disc separating adjacent vertebrae and portions of the adjacent vertebrae to define a graft bed, and inserting into the graft bed at least one porous intervertebral spacer according to the invention.
