ABSTRACT:
A device for accurately determining the lateral recess and foraminal volume prior to and following spinal decompression procedures to assess adequacy of the decompression. The device comprises an inflatable tipped catheter connected to calibration instruments that will correspondingly give volume of inflation of the tip of the catheter which is placed in the lateral recess or nerve root foramen. The readings can be used to determine the extent of the decompression and objectively quantify the extent of such decompression.
