I have one gentleman with multiple surgical procedures including fusions and Harrington rod placements who is left with chronic pain. He has to stand up most of the time. I’m presuming there is a pseudoarthrosis at one level but there is got to be another way then surgery there. Spinal Cord Stimulation (SCS) may help – but the paddles are placed higher than you would think.
SPINAL CORD STIMULATION FOR CONTROL OF LOW BACK PAIN AFTER MULTIPLE CORRECTIVE SURGERIES FOR SEVERE SCOLIOSIS: REPORT OF A CASE

- 48 yr old – 4 prior operations – some Harrington rods un-removable.
- Pain low lumbar and left thigh
- Treatments included most things:
- anti-seizure meds – probably gabapentin
- NSAID’s – anti-inflammatory
- Muscle relaxants
- anti-depressant analgesics
- caudal blocks
- selective nerve blocks
- trigger point injections
- facet injections
- Used Medtronic SCS – position at T7 gave 20% relief, but at T8 gave 60% relief

Effective Cervical Spinal Cord Stimulation for Bilateral Lower Extremities Pain: Technical Report

- severe scoliosis
- multiple lumbar surgeries age 12 on
- decompressive surgery for the lumbar canal stenosis
- kyphoplasty for accident-related compressive fracture in lumbar spine
electromyogram confirmed peripheral lower extremity sensory polyneuropathy
- topical lidocaine patches,
- epidural steroid injections
Two octrodes leads used “from the entry point at T4 to C5 lead tip position”. “His setting during the trial and after the implant was pulse width 500, frequency of 60, amplitude using four different programs varied from 1.8 to 3.2 mA.”
“Although patient complained of significant but tolerable upper extremity paresthesias,
his pain relief was so profound that he opted for the permanent implant.”
This article was meant primarily as a treatment for”four extremity pains” which can be achieve through bilateral stimulation in the neck.
They refer to another articles
“Hagen et al. found in 2005 that eight out of 10 patients suffering from neuropathic pain in all four extremities reported greater than 90% pain relief when SCS was used
through cervical lead placement. However, he found that the four-extremity coverage is achieved only when the leads are placed with their rostral electrode tips at the high C2 region with the leads positioned over the physiological midline.2
Three other reports (two abstracts and one case report1,3,4) suggested a different
“sweet spot” area of four-extremity stimulation. in which 4 extremity pain relief was achieved”
