A rotatable surgical burr ( 100, 200, 300, 500 ) having a protective hood ( 120, 220, 320, 520, 620, 720 ) with a dissecting foot plate ( 119, 219, 319, 519, 619, 719 ) is provided to improve and enable various spinal decompression procedures. The surgical burr's protective hood has a dissecting foot plate that may be shaped to resemble a curette, a Woodson, or other appropriate dissecting tools to allow insertion of the tool between the spinal nerve and the compressing bone. The protective hood surrounds the burr bit ( 130, 230, 530 ) exposing only a portion of the burr bit for burring of the offending bone and protects the nerve from the burr tip. The instrument may also be configured with a soft tissue resecting tip ( 330 ) for soft tissue resection.
