Three groups of dogs were each given repeat epidural injections of a 10% butamben suspension. A fourth group received a single subarachnoid injection of the butamben suspension. All dogs were later sacrificed and the spinal cord, meninges and spinal nerves were examined. The dogs receiving the epidural injections had no pathology. Those dogs that received subarachnoid injections had adhesive arachnoiditis. None demonstrated any evidence of neurolysis. Two cancer patients who had each received multiple injections of a 10% butamben suspension for the successful treatment of cancer pain prior to their deaths had autopsies and the spinal cords, meninges and spinal nerves were examined. No significant pathology due to the butamben was noted. Epidural butamben does not appear to cause any local tissue damage provided that subarachnoid needle placement has been ruled out. Subarachnoid butamben should be avoided.

Terminal cancer patients report substantial pain frequently. Pain control can be achieved in many patients with conventional methods and analgesics. However, significant numbers of patients remain in pain. For these patients, continuous intrathecal narcotics delivered by an external portable pump via a subcutaneous port, offer substantially improved pain control with minimal risk of serious systemic complications. Duration of treatment in our 40 cancer patients lasted up to 11 month. Continuous intrathecal morphine or fentanyl relieved pain till death due to cancer. Supraspinal side effects of opioids were only seen during the first week of intrathecal narcotic treatment. No serious complications like meningitis or other infections were observed. Postmortem examination also could not detect changes of the cord or signs of arachnoiditis due to intrathecal narcotics or the implanted catheter. We conclude, that continuous intrathecal narcotic infusion by means of small portable pump is a very efficient method to control terminal cancer pain and enables treatment on an outpatient basis until death.

Forty-three patients with intractable pain received intrathecal morphine delivered by implanted continuous-infusion (Infusaid) or programmable (Medtronic) devices. In 35 patients the pain was due to cancer, and eight patients had chronic nonmalignant pain. The origin of the nonmalignant pain included lumbar arachnoiditis, multiple sclerosis, severe osteoporosis resulting in a thoracic compression fracture, and intractable pain as a consequence of cancer therapy in individuals cured of their disease. Twenty-eight (80%) of the patients with cancer-related pain experienced excellent or good relief. Side effects were rare. Tolerance occurred infrequently and could be managed effectively. The results of this study support earlier studies on the application of chronic intrathecal morphine for intractable cancer pain. These findings also indicate that, in carefully selected patients, nonmalignant pain may be managed satisfactorily with this technique.

Spinal cord stimulation has been utilized for decades in the treatment of numerous conditions such as failed back surgery and phantom limb syndromes, arachnoiditis, cancer pain, and others. The placement of the stimulating electrode array was originally subdural but, to minimize surgical complexity and reduce the risk of certain postsurgical complications, it became exclusively epidural eventually. Here we review the relevant clinical and experimental pathologic findings, including spinal cord compression, infection, hematoma formation, cerebrospinal fluid leakage, chronic fibrosis, and stimulation-induced neurotoxicity, associated with the early approaches to subdural electrical stimulation of the central nervous system, and the spinal cord in particular. These findings may help optimize the safety and efficacy of a new approach to subdural spinal cord stimulation now under development.
