Neuromodulation in Postherpetic Neuralgia: Case Reports and Review of the Literature.

Objective: Postherpetic neuralgia (PHN) is common in the United States. Current treatment options for PHN are fairly limited. Spinal cord stimulation (SCS) and peripheral nerve stimulation (PNS) are considered mostly experimental and still rarely performed in patients with PHN.

Needle placement for piriformis injection using 3-D imaging.

Piriformis syndrome is a pain syndrome originating in the buttock and is attributed to 6% - 8% of patients referred for the treatment of back and leg pain. The treatment for piriformis syndrome using fluoroscopy, computed tomography (CT), electromyography (EMG), and ultrasound (US) has become standard practice. The treatment of Piriformis Syndrome has evolved to include fluoroscopy and EMG with CT guidance.

Spinal cord stimulator--trial lead migration study.

Objectives: Investigate whether percutaneous spinal cord stimulator (SCS) leads migrate significantly during a 3-day trial, and determine whether the skin anchoring method influences lead migration.

Material And Methods: Twenty patients were prospectively enrolled. Ten leads were anchored with suture and tape and 10 were anchored with tape only.
