Over six years experience with endoscopic spine surgery will be reviewed. Endoscopic surgery has evolved to allow surgeons to evaluate and operate on a variety of conditions that cause discogenic pain. Materials and Methods: From November 1991 to January 1998, 400 patients underwent spinal endoscopy and intradiscal therapy for back and leg pain.
Most patients had proven disc herniations by MRI that failed conservative treatment, but there were subgroups of patients with recurrent disc herniations and discogenic back pain, including annular tears and lateral recess stenosis. Selected subgroups were then treated speciﬁcally for discogenic back pain without radiculopathy in a subsequent investigative series utilizing radio frequency.
