4. Cervical Radicular Pain

PAIN PRACTICE, Issue 1 2010
FIPP, Jan Van Zundert MD
Abstract Cervical radicular pain is defined as pain perceived as arising in the arm caused by irritation of a cervical spinal nerve or its roots. Approximately 1 person in 1,000 suffers from cervical radicular pain. In the absence of a gold standard, the diagnosis is based on a combination of history, clinical examination, and (potentially) complementary examination. Medical imaging may show abnormalities, but those findings may not correlate with the patient's pain. Electrophysiologic testing may be requested when nerve damage is suspected but will not provide quantitative/qualitative information about the pain. The presumed causative level may be confirmed by means of selective diagnostic blocks. Conservative treatment typically consists of medication and physical therapy. There are no studies assessing the effectiveness of different types of medication specifically in patients suffering cervical radicular pain. Cochrane reviews did not find sufficient proof of efficacy for either education or cervical traction. When conservative treatment fails, interventional treatment may be considered. For subacute cervical radicular pain, the available evidence on efficacy and safety supports a recommendation (2B+) of interlaminar cervical epidural corticosteroid administration. A recent negative randomized controlled trial of transforaminal cervical epidural corticosteroid administration, coupled with an increasing number of reports of serious adverse events, warrants a negative recommendation (2B,). Pulsed radiofrequency treatment adjacent to the cervical dorsal root ganglion is a recommended treatment for chronic cervical radicular pain (1B+). When its effect is insufficient or of short duration, conventional radiofrequency treatment is recommended (2B+). In selected patients with cervical radicular pain, refractory to other treatment options, spinal cord stimulation may be considered. This treatment should be performed in specialized centers, preferentially study related. [source]

Spinal Cord Stimulation for Failed Back Surgery Syndrome

NEUROMODULATION, Issue 1 2001
Jean-Christophe Leveque BA
Objective. The purpose of this study is to evaluate the effectiveness of modern spinal cord stimulation (SCS) for the treatment of failed back surgery syndrome (FBSS). Materials and Methods. Thirty patients were treated with SCS between December 1992 and January 1998 for low back and radicular pain after multiple failed back surgeries. Permanent systems were implanted if trial stimulation led to > 50% pain reduction. Median long-term follow-up was 34 months (range, 6,66 months). Severity of pain was determined postoperatively by a disinterested third party. Results. Overall, 12 of the 16 patients (75%) who received permanent implants continued to report at least 50% relief of pain at follow-up. All six patients who underwent placement of laminectomy-styled electrode for SCS in the thoracic region had > 50% pain relief at long-term follow-up. Visual analog scores decreased an average of 3.2 (from 8.6 preoperatively to 5.4 postoperatively). Patients undergoing SCS placement via laminectomy in the thoracic region experienced an average decrease of 4.9 in VAS, whereas those who underwent percutaneous placement of thoracic leads had an average decrease of 2.5. Conclusions. SCS is an effective treatment for chronic low back and lower extremity pain which is refractory to conservative therapy and which is not amenable to corrective anatomic surgery. Though our patient population is small, our results imply that the laminectomy-style electrodes in the thoracic region achieve better long-term effectiveness than percutaneous leads. [source]

EPIDUROGRAPHY: CHARACTERISTICS OF EPIDURALGRAMS PERFORMED DURING LESI

PAIN MEDICINE, Issue 2 2002
Article first published online: 4 JUL 200
David C. Miller MD, DABPM Woodland Pain Center, Michigan City, IN Fluoroscopically guided, contrast enhanced lumbar epidural steroid injections are commonly performed for persistent or sever lumbar radicular pain. An epiduralgram is a real-time fluoroscopic image of contrast injected into the epidural space prior to the injection of local anesthetic and steroid. This report details the results of one hundred consecutive epiduralgrams. The epidural needle was placed under continuous multiplainer fluoroscopic guidance using ISIS protocol. Three ml. of Omnipaque 300 were injected after initial insertion to obtain the epiduralgram. This was followed by injection of 3 ml. of Celestone diluted with 4 ml. of preservative-free 1% lidocaine to obtain the epiduralgram. The epidural needle was placed at the predetermined spinal level and appropriate side 100% of the time. Needles were successfully placed into the epidural space on the first attempt in 95%. One needle was subarachnoid, one was intra vascular, three were in tissue plains superficial to the epidural space and were apparent only with contrast injection. Three ml. of contrast flowed unilaterally in 74% of lumbar epidural injections. The contrast flowed cephalad only in 20%, caudad only in 28%, and bidirectional in 52%. Contrast spread less than three spinal levels 64% of the time. The desired nerve root was visualized in 62%. Contrast was seen in the ventral epidural space on lateral views 88% of the time. Ventral spread was always fewer levels than the dorsal spread. Epidurography provides essential information for the accurate performance of lumbar epidural steroid injections. One out of every twenty presumed epidural injections were inaccurately placed even by an experienced operator. One out of every fifty was dangerously positioned and identified only by performance of an epiduralgram. [source]

4. Cervical Radicular Pain

Cell Types Obtained from the Epidural Space of Patients with Low Back Pain/Radiculopathy

PAIN PRACTICE, Issue 3 2009
James E. Heavner PhD
Abstract Background: We investigated if correlations exist between medical history, tissue abnormalities, and cell types retrieved from the epidural space of patients with chronic low back pain (LBP) and chronic radicular pain (RP). Methods: Approval was obtained from the Institutional Review Board for the Protection of Human Subjects to study 191 patients undergoing epiduroscopy. Visual inspection was performed and abnormal areas were identified. A specimen obtained from the area using a cytology brush was processed by the Thin Prep technique. Patients were divided into four groups based on the presence or absence and intensity of LBP and RP. The gender and age of the patients were recorded, as was any history of prior back surgery. Areas of tissue abnormalities were rated according to changes in vascularity and amount of fat, fibrosis, and inflammation. Stenosis was assessed from magnetic resonance imaging or computerized tomography scan images. Cytologic assessments included notations of the presence or absence of erythrocytes, leukocytes, cell groups, lipocytes, spindled cells, and large round cells. Results: There was a significant difference in the number of patients from whom big round cells were obtained who had a high degree of LBP compared with the number of patients who had a high degree of both LBP and RP. Conclusions: The findings provide a foundation for future studies of cells obtained from similar patients with the goal of furthering the understanding of the pathogenesis of LBP/RP. [source]

Acute Monoplegia After Lysis of Epidural Adhesions: A Case Report

PAIN PRACTICE, Issue 5 2008
DAAPM, Kok-Yuen Ho MBBS, MMed (Anaes)
Abstract Lysis of epidural adhesions is an interventional procedure performed to treat refractory low back pain or radicular pain due to epidural scarring. A 39-year-old female with a diagnosis of failed back surgery syndrome underwent lysis of epidural adhesions using a Racz catheter. She developed acute monoplegia of her right lower extremity immediately after the procedure. Radiographic imaging did not reveal an epidural hematoma. Motor and sensory function in the right lower limb returned after 5 days. Large volumes of fluid injected during neuroplasty could have caused transient nerve injury from compression within loculated epidural compartments. [source]

Trans-facet Joint Approach to Pulsed Radiofrequency Ablation of the L5 Dorsal Root Ganglion in a Patient with Degenerative Spondylosis and Scoliosis

PAIN PRACTICE, Issue 3 2008
David Abejón MD, FIPP
,,Abstract: Mechanical low back pain secondary to degenerative facet joint changes is a common reason for referral to pain clinics. When these changes cause encroachment into the intervertebral foramen, radicular pain may result. While pulsed radiofrequency of the dorsal root ganglion can be used in this setting, the anatomic deformity may make the transforaminal approach difficult. We report a case where a trans-facet approach was used successfully and describe the technique.,, [source]

MULTIDISCIPLINARY PAIN ABSTRACTS: 50

Degenerative disease of the spine is one of the most common clinical entities and affects the intervertebral discs, including opposing vertebral endplates, the intervertebral posterior joints and the ligaments. The most severe primary spinal degenerative changes are found in the lower cervical and lumbar spine regions. The spine contains three different types of joints, each of which presents its own pattern of degenerative disease: cartilaginous joints, synovial joints, and fibrous joints. With regard to radicular pain, root compression alone does not fully account for root pain following disc-root conflict, but it is, nevertheless, considered to be the main cause of pain. The authors pointed out that the origin of pain is multi-factorial and that inflammation probably predominates over merely mechanical mechanisms. They also considered whether vertebral arthrosis can be construed as the body's decision to favor the spine's static function over its dynamic role when joint "hypermobility" linked to chronic load in old age could cause severe structural damage to the bony vertebral structures.

MULTIDISCIPLINARY PAIN ABSTRACTS: 47

PAIN PRACTICE, Issue 1 2004
Article first published online: 15 MAR 200
The purpose of this multicenter, randomized, controlled trial was to compare the effect of manual therapy to exercise therapy in sick-listed patients with chronic low back pain. The effects of exercise therapy and manual therapy on chronic low back pain with respect to pain, function, and sick leave have been investigated in a number of studies. The results are, however, conflicting. Patients with chronic low back pain or radicular pain sick-listed for more than 8 weeks and less than 6 months were included. A total of 49 patients were randomized to either manual therapy (n=27) or to exercise therapy (n=22). Sixteen treatments were given over the course of 2 months. Pain intensity, functional disability (Oswestry disability index), general health (Dartmouth Care Cooperative function charts), and return to work were recorded before, immediately after, at 4 weeks, 6 months, and 12 months after the treatment period. Spinal range of motion (Schober test) was measured before and immediately after the treatment period only. Although significant improvements were observed in both groups, the manual therapy group showed significantly larger improvements than the exercise therapy group on all outcome variables throughout the entire experimental period. Immediately after the 2-month treatment period, 67% in the manual therapy and 27% in the exercise therapy group had returned to work. It was concluded that improvements were found in both intervention groups, but manual therapy showed significantly greater improvement than exercise therapy in patients with chronic low back pain. The effects were reflected on all outcome measures, both on short- and long-term follow-up. [source]

Adalimumab in severe and acute sciatica: A multicenter, randomized, double-blind, placebo-controlled trial,

ARTHRITIS & RHEUMATISM, Issue 8 2010
Stéphane Genevay
Objective Based on several experimental results and on a preliminary study, a trial was undertaken to assess the efficacy of adalimumab, a tumor necrosis factor , inhibitor, in patients with radicular pain due to lumbar disc herniation. Methods A multicenter, double-blind, randomized controlled trial was conducted between May 2005 and December 2007 in Switzerland. Patients with acute (duration of <12 weeks) and severe (Oswestry Disability Index score of >50) radicular leg pain and imaging-confirmed lumbar disc herniation were randomized to receive as adjuvant therapy either 2 subcutaneous injections of adalimumab (40 mg) at 7-day intervals or matching placebo. The primary outcome was the score for leg pain, based on a visual analog scale (0,100 mm), which was recorded every day for 10 days and at 6 weeks and 6 months. Results Of the 265 patients screened, 61 were enrolled; 31 patients were assigned to receive adalimumab, and 4 patients in the placebo group were lost to followup. Over time, the course of leg pain was more favorable in the adalimumab group than in the placebo group (P = 0.002). However, the effect size was relatively small, and at the last followup visit the difference was 13.8 (95% confidence interval ,11.5, 39.0). Compared with patients in the placebo group, approximately twice as many patients in the adalimumab group fulfilled the criteria for "responders" and for "low residual disease impact" (P < 0.05), and fewer surgical discectomies were performed (6 versus 13 in the placebo group; P = 0.04). Conclusion The addition of a short course of adalimumab to the treatment regimen of patients experiencing acute and severe sciatica resulted in a small decrease in leg pain and in significantly fewer surgical procedures.

A case of idiopathic spinal epidural lipomatosis presented with radicular pain caused by compression with enlarged veins surrounding nerve roots

ACTA NEUROLOGICA SCANDINAVICA, Issue 4 2002
M. Kawai
Objective, To report a case of idiopathic spinal epidural lipomatosis (SEDL) presented with unique radicular pain most likely caused by enlarged veins surrounding nerve roots. Patient, A 26-year-old male presented with radicular pain of the right T6,T7 area. He also showed Becker's nevus in the corresponding area. CT myelography and magnetic resonance imaging revealed epidural lipomatosis posterior to T4,T8 of the spinal cord. Surgical removal of adipose tissue and a hemilaminectomy of T4,T7 were performed and resulted in relief of the radicular pain. Conclusions, Lipomatosis was histologically confirmed and surrounded by enlarged veins. These abnormally enlarged veins compressed the nerve roots and were thought to cause radicular pain. Also, Becker's nevus of this case seems to have some relationship with SEDL. [source]
