ABSTRACT:
Decompression of herniated discs in the lumbar spine is carried percutaneously by the insertion of a specially designed cannulated trocar over a guide wire extending through the patient's back toward the herniated disc at an angle of approximately 35 degrees with respect to the patient's perpendicular line. A thin-walled cannula is passed over the trocar, and a hollow cutting instrument is inserted through the cannula to form a window in the disc. Disc fragments are removed through the cannula by means of a special punch forceps, after the application of suction to the disc nucleus through the cutting instrument.
