Pain Neurosurgery Program

Directors: Oren Sagher, MD and Parag G. Patil, MD, PhD

The Pain Neurosurgery Program provides a comprehensive and technologically advanced approach to the treatment of pain. Patients are referred to the program after failing to achieve adequate control of their pain with tolerable doses of oral pain medications. The program works closely with the Center for Interventional Pain Medicine in the Department of Anesthesia to insure that optimal therapeutic interventions are provided to each patient. These approaches may include a new and innovative medication regimen, an implanted analgesic pump, a spinal cord stimulator, a motor cortex stimulator, a deep brain stimulator, or open surgery to interrupt pain signaling pathways, thereby treating pain. Patients under consideration for device-based therapies typically will undergo a trial of therapy prior to permanent implantation of a pain-modulating device. Patients evaluated in our program typically see both Neurosurgery and Pain Psychology in a single visit, as part of a coordinated appointment. In this comprehensive evaluation, we look at all previous treatments, and incorporate physical finds, imaging correlates, as well as a detailed psychological profile of each patient, before arriving at a plan of treatment. We evaluate the possibility of anatomical correction, as well as possible neuromodulation options - such as electrical neurostimulation and pump infusion therapies. Finally, the possibility of ablative treatments is entertained. Pain Procedures performed in our program include:

  • Spinal Cord Stimulation
  • Peripheral Nerve Stimulation
  • Intrathecal Drug Therapy
  • Dorsal Root Entry Zone Lesion (DREZ)
  • Cordotomy
  • Myelotomy
  • Neurectomy
  • Deep Brain Stimulation
  • Microvascular Decompression
  • Rhizolysis
  • Motor Cortex Stimulation

Today, pain treatment can help restore quality of life and improve patient function. We offer a wide range of treatments at our program for conditions such as:

  • Back and neck pain
  • Sciatic pain
  • Cancer pain
  • Facial pain
  • Headaches and migraines
  • Shingles and postherpetic neuralgia (nerve pain after shingles) 
  • Complex regional pain syndrome (CRPS)/Reflex sympathetic dystrophy (RSD)
  • Painful neuropathy

Our pain management experts provide consultations to patients and physicians in Southeast Michigan, and the entire tri-state region. Patients with uncontrolled pain due to cancer, nerve and nervous system injury, stroke, failed back surgery, limb amputation, trigeminal neuralgia, and other causes may all be candidates for these advanced pain therapies.
