What is SED/YESS?
Selective Endoscopic Discectomy™ (SED™) is a minimally invasive spine surgery technique that utilizes an endoscope to treat herniated, protruded, extruded, or degenerative discs that are a contributing factor to leg and back pain. The endoscope allows the surgeon to use a “keyhole” incision to access the herniated disc. Muscle and tissue are dilated rather than being cut when accessing the disc. This leads to less tissue destruction, less postoperative pain, quicker recovery times, earlier rehabilitation, and avoidance of general anesthesia. The excellent visualization via the endoscope permits the surgeon to selectively remove a portion of the herniated nucleus pulposus that is contributing to the patients’ leg and back pain.
Thermal annuloplasty is an adjunctive procedure that uses bipolar electro-thermal energy (radiofrequency and/or laser) to ablate or depopulate the sensitized pain nociceptors in the annulus, ablate any inflammatory/grannualtion tissue that has grown into the annulus, and to shrink and tighten the stretched or torn collagen fibers of the annulus. The annulus is the outer portion of the disc and is composed of many concentric layers that are arranged similarly to the plies of a radial tire. Thus, the weakened annulus or defect left by the disc herniation is contracted and possibly sealed from within the disc.
