Reciprocating cutting apparatus and methods for removing tissue from an intervertebral disc are disclosed. The reciprocating cutting apparatus can include a guide tube, a cutting cap and a drive shaft. Other reciprocating cutting apparatus can include a guide tube, an outer guide tube, a cutting cap and a drive shaft. The cutting cap reciprocates relative to the distal opening in the guide tube to cut and/or abrade tissues within an intervertebral disc. A cutting member may be provided to assist in the cutting and/or abrading of the tissues within the intervertebral disc. The reciprocating cutting apparatus may be generally configured to extend and withdraw a guide tube from and into the distal opening in the outer guide tube.
