Epidural injections with or without steroids are used extensively in the management of chronic spinal pain. However, evidence is contradictory with continuing debate about the value of epidural steroid injections in chronic spinal syndromes. The objective of this systematic review is to determine the effectiveness of epidural injections in the treatment of chronic spinal pain. ⋯ Further, evidence was moderate for caudal epidural injections in managing lumbar radicular pain. The evidence in management of chronic neck pain, chronic low back pain, cervical radiculopathy, spinal stenosis, and post laminectomy syndrome was limited or inconclusive. In conclusion, the evidence of effectiveness of transforaminal epidural injections in managing lumbar nerve root pain was strong, whereas, effectiveness of caudal epidural injections in managing lumbar radiculopathy was moderate, while there was limited or inconclusive evidence of effectiveness of epidural injections in managing chronic spinal pain without radiculopathy, spinal stenosis, post lumbar laminectomy syndrome, and cervical radiculopathy.

The objective of this study was to compare the cost and safety of intrathecal injection (IN) vs. epidural infusion (CE) trial and to provide a preliminary assessment of the prognostic value of each in the selection of patients for long-term continuous intrathecal opioid therapy (CIOT). Thirty-seven patients with chronic nonmalignant pain who were being considered for CIOT were randomized to morphine trial by IN or CE. Analgesic response and complications were monitored throughout trial. ⋯ There was no difference between IN and CE groups in McGill Pain rating, quality of life (VAS), mood (Profile of Mood States), or function (Sickness Impact Profile) after six months of CIOT. We conclude that intrathecal injection is a safe procedure for use in selection of patients for CIOT and is less costly than epidural infusion. Differences in pain and functional response to long-term opioids among patients selected by either trial method are not large.

The Model 8831 Personal Therapy Manager (PTM) offers a patient-controlled analgesia (PCA) option for the SynchroMed Infusion System (Medtronic Inc., Minneapolis, MN). The safety and effective operation of the PTM activator was evaluated in 45 patients in five European centers receiving intrathecal drug infusion for the treatment of chronic pain via a SynchroMed pump. The total volume of drug delivered intrathecally over a four-week follow-up period was calculated. ⋯ Patients appreciated being able to control their pain and considered the device and its instructions easy to use. The PTM was shown to be safe and functioning properly in the intrathecal treatment of pain. The successful addition of a PCA function to the SynchroMed system may create a new standard in intrathecal pain therapy.

While spinal cord stimulation has commonly been carried out using percutaneous leads, these devices have limitations in cervical implants due to problems with positional stimulation and lead migration. Paddle leads, by virtue of their design, are more stable in their apposition to the neural elements; however, mid and lower cervical insertions have been associated with both acute and subacute spinal cord injuries. These complications are likely related to limitations in canal diameter, as paddle leads occupy a greater volume than percutaneous leads. ⋯ No patient suffered neurologic sequelae as a result of this procedure. We have found C1-C2 sublaminar insertions of paddle leads to be a safe and effective way of treating neuropathic pain phenomenon involving the upper extremity. To further assess the relative benefit over percutaneous leads, a prospective trial would be required.

The intervertebral disc is the focal point of pathology for most low back pain. Contained disc herniation is a common cause of low back pain and, when unresponsive to conservative measures, is often treatable by disc decompression. To evaluate the safety and efficacy of percutaneous disc decompression using Coblation (Nucleoplasty) in the treatment of back and/or leg pain associated with contained disc herniation, a prospective, nonrandomized cohort analysis was conducted in an interventional pain management practice. ⋯ Additionally, significant improvement was reported by 54%, 44%, and 49% of patients in sitting, standing and walking abilities, respectively, at 12 months. There were no instances of complications. These results indicate that disc decompression using Coblation (Nucleoplasty) is a safe and efficacious procedure for reducing discogenic low back pain with or without leg pain.
