Objective. This study examines, in a retrospective fashion, the effects of intraspinal infusion therapy, primarily using opioids, in the treatment of recalcitrant noncancer pain in a sample of 29 consecutive patients. Patients were, on average, 58 years of age having had one surgery, with a pain duration of 221 months. ⋯ Side effects remain fairly common and require continued attention. Their presence, however, did not appear to deter from the patient's overall sense of satisfaction. Acquiring information from significant others and clinic staff may be a useful adjunct in interpreting the overall outcome.

Objective. Follow-up of 80 patients using multiple program spinal cord stimulation (SCS). Methods. ⋯ Conclusions. In spinal cord stimulation the use of multiple electrodes and multiple stimulation programs, together with advanced programmability, increases paresthesia overlap, reduces pain scores, and may improve patient satisfaction with SCS therapy. This study indicates a significant patient preference for multiple program SCS, if patients are given the option to choose between a single program SCS system or a multiple program SCS system.

Objective. Treatment of pain associated with failed back surgery syndrome was evaluated in a pilot clinical study of a new dual lead spinal cord stimulation (SCS) system. Methods. ⋯ While external hardware problems occurred, 65% of dual lead SCS patients were willing to repeat the SCS implant procedure. Conclusions. Dual lead stimulation proved beneficial for patients with low back and leg pain associated with failed back surgery syndrome.

Objective. Since 1996 we have placed temporary catheters at the cervical nerve roots in chronic pain patients for the treatment of radiculopathy and complex regional pain syndrome. We investigated the possibility of placing electrodes both at the cervical spinal nerve and dorsal root ganglion for the purpose of neuromodulation. ⋯ Conclusions. In human cadavers, a percutaneous technique was successful in the placement of neurostimulator electrodes at the cervical and upper thoracic nerve roots using a novel trans-spinal approach. New smaller electrode systems that can be placed in a transforaminal position safely may be needed.
