Sarcopenia and Outcomes of Neuroplasty in Lumbar Spinal Stenosis

The patient is placed in the prone position with a pillow placed under the abdomen to correct the lumbar lordosis. After sterile preparation and draping, the epidural space via the sacral hiatus using a 16 gauge needle is accessed. Then, the Racz catheter is advanced to the site of adhesions under the fluoroscopic guidance. The target site is determined by the location of pathology on lumbar MRI, preprocedural epidurography, and clinical symptoms before the adhesiolysis. Adhesiolysis is performed through the high-volume administration of medications, which consist of a combination of a steroid, local anesthetics, hyaluronidase, and 5% hypertonic saline. As needed, the catheter remains in the epidural space for two days, with the additional injection on each of the days.
