for the treatment of CRPS I and causalgia (CRPS II) of the. Rates of paddle migration vary between series from 3 to 32 27. The only FDA-approved dorsal root ganglion (DRG) technology. The device obtained positive feedback during cadaver labs with orthopedic surgeons and could be manufactured in the future as a viable product. Presurgical and postsurgical care of the patient undergoing dorsal column stimulation with both percutaneous leads and surgical (paddle) leads are reviewed in this chapter, with attention given to the technical details of the procedures as well as commonly encountered complications. 15.1 Intraoperative fluoroscopic image showing a thoracic multi column paddle electrode covering the entire vertebral body of T9 with some coverage over the T8/T9 disc space Lead migration and infection are common forms of spinal cord stimulator failure 26. The tool has a footprint 50% smaller than the available space through which to traverse to access the DRG and can overcome the estimated 1.7 lb force of the surrounding ligaments. Since these thresholds have a small ratio (1:1.4), stimulation of the dorsal column fibers and paresthesia coverage is limited by this small range of stimulation. This project seeks to create a novel surgical tool to assist in delivering a stimulating paddle into the intervertebral foramen via a stylet-retractor mechanism. The major challenge with delivering a paddle electrode is accessing the DRG without damaging the root. Rats were implanted with cortical recording microelectrodes and spinal cord stimulating electrodes, and then injected with pentylenetetrazole to induce seizures. Paddle stimulators have been shown to have more targeted therapy, are more energy efficient, and be more versatile by having a larger number of electrode contacts than traditional cylindrical leads. Here we demonstrate a closed loop brain-machine interface that delivers electrical stimulation to the dorsal column (DCS) of the spinal cord to suppress epileptic seizures. This method shows promise over traditional spinal cord stimulation due to the its localized nature as opposed to stimulating the entire dorsal column. Odds of SCI increased by 2.428 (95 CI 1.4064.193) if patient took any anticoagulant within 30 days before the procedure. CoverEdge Surgical Leads are available exclusively for the Precision Spectra SCS System.Dorsal root ganglion (DRG) stimulation is a novel method of treating chronic pain in which a lead with a set of electrodes is placed on the nerve root of the spinal cord above the pain site. In implantation of percutaneous and paddle electrodes for SCS, 59 of 8,326 patients (0.71) experienced spinal hematoma (percutaneous 41 0.75 vs paddle 18 0.63, P 0.52). The CoverEdge X 32 Surgical Lead offers the broadest vertebral span among multi-column paddles. Available in two configurations, the CoverEdge 32 Surgical Lead features 32 tightly spaced contacts in a four-column array for seamless coverage and precise pain targeting. Available in two configurations, the CoverEdge 32 Surgical Lead features 32 tightly spaced contacts in a four-column array for seamless coverage and precise. The world’s first and only 32 contact paddles, the CoverEdge Family of Surgical Leads blanket the spinal cord for unprecedented coverage. The SCS electrodes can be placed either percutaneously (ie, cylindrical electrodes) or surgically through a laminotomy or laminectomy (ie, surgical paddle electrode). The world’s first and only 32 contact paddles, the CoverEdge Family of Surgical Leads blanket the spinal cord for unprecedented coverage. CoverEdge & CoverEdge X 32 Surgical Leads. The ideal electrode position is the guarantee of treatment effect. For patients receiving multi-column paddle operations, the deviation of the electrode may result in only one contact in a pair that covers the midline. In our study group, the lead most commonly used, seen in 12 of 36 cases (33.3), contained an eight-contact paddle electrode all were permanently implanted. CoverEdge™ & CoverEdge X 32 Surgical Leads During the surgical procedure, some patients single-column paddle may not completely cover the dorsal column. Both surgical paddle electrodes and percutaneous electrodes are available for trials and implantations.
