The authors perform the procedure under general anesthesia with the head stabilized in a Mayfield head frame so as to obtain maximum flexion and temporary reversal of the cervical lordosis. The authors always obtain an MRI prior to paddle implant in order to assess canal diameter so an appropriately sized paddle may be selected. Additionally, preoperative imaging with cervical MRI is more critical in this region leading some authors to uniformly recommend it preoperatively. Unsurprisingly, there is reportedly a higher rate of lead migration in the cervical spine than the thoracic spine. However, some authors’ enthusiasm for cervical spinal cord stimulation is tempered by the challenge of securing an electrode in this inherently more flexible region. Dorsal column stimulation, more commonly known as spinal cord stimulation (SCS), is a safe and effective therapy used to help treat intractable chronic neuropathic pain, stemming most commonly from failed back surgery syndrome (FBSS) and complex regional pain syndrome (CRPS). Paddle leads, by contrast, are larger and usually anchored to the spinal column under a small piece of bone during a laminectomy procedure. Percutaneous leads are inserted into the spine with an epidural needle and are smaller and easier to remove. Subsequent to this, he underwent placement of a Medtronic Specify 3998 paddle lead (Medtronic Neurologic, Minneapolis, MN, USA) at the T9-T10 levels. There are two categories of leads: percutaneous and paddle.

Device Trade Name: Senza Spinal Cord Stimulation (SCS) System. The patient is a 59-year-old man with postlaminectomy syndrome, who underwent a successful percutaneous SCS trial at an outside institution. In order to obtain coverage in the neck and upper extremity, an upper cervical vertebral body is typically targeted. Spinal Cord Stimulation Treatment Type Timing Purpose MRI or CT myelogram of lumbar spine Before SCS screening trial Establish diagnosis of FBSS. Device Generic Name: Stimulator, Spinal-Cord, Totally Implanted For Pain Relief. Neuromodulation via cervical stimulation is often utilized to control neck and upper extremity pain. In this study, we compared the long-term outcomes and health-care costs associated with paddle and percutaneous lead implantation. The expected positioning of SCSs based on the location of pain, the types of electrodes (percutaneous vs surgical paddle), and the types of electrode arrays and the potential complications have not been described to date in the radiology literature.
