Abstract

Based on the available evidence, the Therapeutics and Technology Assessment subcommittee concluded that 1) epidural steroid injections may result in some improvement in radicular lumbosacral pain when assessed between 2 and 6 weeks following the injection, compared to control treatments (Level C, Class I-III evidence). The average magnitude of effect is small and generalizability of the observation is limited by the small number of studies, highly selected patient populations, few techniques and doses, and variable comparison treatments; 2) in general, epidural steroid injection for radicular lumbosacral pain does not impact average impairment of function, need for surgery, or provide long-term pain relief beyond 3 months. Their routine use for these indications is not recommended (Level B, Class I-III evidence); 3) there is insufficient evidence to make any recommendation for the use of epidural steroid injections to treat radicular cervical pain (Level U).

Chronic back pain and its associated disabilities represent an important health problem.1 The rising prevalence of obesity may increase the impact of chronic back pain. The competitive nature of the modern workplace places individuals with less than perfect health and, in particular, those with painful conditions at a disadvantage. Workplace accommodation may not be an option for many occupations and, even where possible, is frequently linked with economic losses for employee and employer alike.

In 1998, individuals with back pain in the United States were estimated to have incurred total health care expenditures of $90.7 billion.2 Inpatient care accounted for 31% of the expenditure, followed by expenditure for office-based visits (26%), prescription drugs (15.6%), and outpatient services (13.1%). Emergency department visits and home health visits each accounted for 3%. Of the $90.7 billion total expenditures incurred by these individuals, the expenditures attributable directly to the back pain totaled approximately $26.3 billion,2 of which 42% were for office-based visits, 18% for outpatient services, 17% for inpatient care, 15% for prescription drugs, and 4% for emergency room visits. The estimated cost of treatments for spinal pain (medical therapy, epidural steroid injections, spinal cord stimulation, and intrathecal narcotics) for 1990 was at least $13 billion, growing by 7% per year.3 Medicare part B claims in 1999 for 40.4 million covered individuals were $49.9 million for lumbar epidural steroid injections, $8.5 million for lumbar facet or peri-facet joint injections, and $5.6 million for cervical or thoracic epidural steroid injections.4

Low back pain may occur without or with radicular features (the latter often referred to as sciatica). In the strictest sense, sciatica refers to pain running down the posterior aspect of the lower extremity. A less restrictive usage to refer to lower back pain with radiation is found in the literature reviewed for this report. A structural cause for sciatica, such as a herniated disc or foraminal stenosis, may or may not be found with investigations. Abnormalities on imaging may be seen in asymptomatic subjects, thus it may not be correct to infer a causal role for radiologic structural changes even if they are concordant with the distribution of sciatica.

Reports of epidural corticosteroid injections to treat sciatica date back to the 1950s.5,6 Their use has increased over time despite limited quality data, as reflected by conflicting reviews of their efficacy and safety.7–9 These reviews varied in terms of criteria for inclusion of patients, study design, types of interventions, outcome measures, and use of additional treatments. A recent review (2004) by the Technology Assessment Committee of the Institute of Clinical Systems Improvement (ICSI)10 focused on fluoroscopically guided, transforaminal epidural steroid injections in radicular lumbar pain. Although it used an evidence-based approach, the rating system is different from that of the American Academy of Neurology (AAN). It concluded that, even though results based on limited data appeared to be promising, there was insufficient evidence to comment on the efficacy of transforaminal epidural steroid injections in radicular lumbar pain.10

A recent editorial11 discussing the role of placebo-controlled trials emphasizes that pain treatments considered effective based on uncontrolled clinical observations or case studies may be found to be ineffective when tested within well-designed placebo-controlled studies. To avoid this error, higher quality evidence requires performance of studies incorporating rigorous case definition, use of controls (placebo or active), use of a standardized efficacy scale, masking of patient and evaluator regarding treatment, and gathering of safety data in different treatment arms. The data should permit calculation of the number of patients needed to treat in order to make one more patient better than what would be obtained with a control treatment (placebo or alternative active treatment).

A listing of important questions regarding epidural steroids appears in table 1. However, the number of high quality of studies was limited. Therefore, the question “What is the evidence to support use of epidural steroid injections in radicular lumbosacral pain to produce pain relief?” was dealt with first. Other endpoints considered within the higher quality studies so identified were considered, as were endpoints identified by reviewers for which there were high quality data.

Table 1 Epidural steroid use: Questions for consideration

Methods.

Efficacy.

Medline searches were conducted in April 2003 and February 2005 using combinations of the terms “epidural injections” or “epidural steroids,” “double-blind,” “placebo-controlled,” and “radiculopathy.” A search of the Cochrane database of systematic reviews found no review on the use of epidural steroid injections to treat radicular pain. The following inclusion criteria were used:

  • 1) clear case definition;

  • 2) clear measure of outcome (pain relief) using a standardized measure;

  • 3) use of a control group (placebo or active);

  • 4) randomization;

  • 5) at least double-blind study design, so that neither patient nor assessor of measure of outcome would know the treatment arm; or triple-blind, if the physician injecting the treatment also did not know what treatment was administered;

  • 6) prospective study design;

  • 7) adequate statistical analysis.

The references of articles identified primarily and within select review articles were scanned for additional articles meeting the inclusion criteria: none were found. Articles identified by reviewers of earlier versions of the manuscript were considered also. The highest level of evidence was used to make the conclusions and recommendations for this parameter. Since articles on epidural steroid treatment of radicular cervical pain did not meet these criteria, epidural steroids to treat radicular lumbosacral pain alone will be considered.

Safety.

A separate Medline search using the key words “epidural steroid” and “complications” was performed to identify reported complications with the procedure. Results from selected articles and from the efficacy studies selected for inclusion are summarized briefly.

Results.

Efficacy.

The search yielded 37 articles, 4 of which met the predetermined inclusion criteria.12–15 These are summarized in an evidence table (table 2). Full review of a fifth article16 resulted in its exclusion since outcome measures were unclear, times for the reported outcomes were uncertain, and results of statistical analysis for the outcomes of interest were unavailable. The two articles identified as of the highest quality in the ICSI review17,18 were summarized also in table 2. Some of the studies combined steroids with a local anesthetic, using the local anesthetic as a control or normal saline as the control, while others compared steroids to normal saline.

Safety.

The most common complication is a transient headache whether or not associated with identifiable dural puncture.14 More serious complications, summarized in a 1996 review,19 were several cases of aseptic meningitis, arachnoiditis, and conus medullaris syndrome, typically after multiple subarachnoid injections. Two cases of epidural abscess, one case of bacterial meningitis, and one case of aseptic meningitis were also listed (subarachnoid drug placement could not be ruled out in the meningitis cases).19 A retroperitoneal hematoma was reported in one patient on anticoagulant therapy who received a fluoroscopically guided transforaminal injection of steroids.18 Transient complications have been encountered also during fluoroscopically guided caudal epidural injections, including insomnia, transient non-positional headaches, increased back pain, facial flushing, vasovagal reactions, nausea, and increased leg pain.20 No major neurologic complications (spinal hematomas) were encountered in a series of 1,035 individuals who received epidural steroid injections while on antiplatelet therapy.21 Minor complications (blood during needle placement) were encountered in 5.2%, and transient worsening of symptoms or emergence of new neurologic symptoms for more than 24 hours after the injection occurred in 4% of patients with median duration of 3 days and range 1 to 20 days. Additional qualitative safety data reporting serious complications were rare.21 An additional potential risk of radiographically guided transforaminal injections is radiation exposure; however, the radiation exposure of the spinal interventionalist was well within safety limits if proper techniques were followed.22

The role of practitioner experience and radiologic confirmation of needle placement cannot be determined based on these reports. The results of the one high quality study with radiologic confirmed needle placement did not provide direct comparison of techniques. Therefore, the utility of, or need for, fluoroscopic confirmation of needle placement is unclear.

Discussion.

Comparison to the results of the ICSI review.

This evidence-based review focusing specifically on fluoroscopically guided transforaminal epidural injections10 identified two studies it considered of high quality, which had not been identified by the Medline searches. One article studied pain relief,18 and we concurred that it was of high quality (Class I evidence). Its results were consistent with studies performed without radiologic guidance. The second article used avoidance of surgery as its primary outcome measure.17 However, methodologic limitations resulted in a lower rating under our system (Class III evidence). The limitations included small sample size, the highly selected sample due to self-selection of participants, imprecise case definition, lack of control for possible confounding factors, and insufficient information about why subjects proceeded to surgery. Its findings favoring efficacy, while concordant with those of a previously identified article,13 were discordant from those of articles that were rated higher, that showed no impact on utilization of surgery.14,18 The lack of overlap between high quality articles found using the two search strategies resulted from use of different search terms. The ICSI review did not retrieve articles that did not use fluoroscopy, and the high quality article reporting results with transforaminal, peri-radicular injections using fluoroscopy did not incorporate the terms we had used in our original search. However, the results with the two search strategies were similar, strengthening the validity of our conclusions and recommendations.

Principal findings, in clinical perspective.

With regards to the primary question of this review, amelioration of pain, the findings of the four high quality studies12–14,18 are internally consistent, showing the following efficacy pattern compared to a control group: no efficacy at 24 hours12; some efficacy at 2 to 6 weeks13,14,18; no difference14 or rebound worsening at 3 months18 and 6 months18; and no difference at 1 year.13,18 The immediate postinjection amelioration of leg, but not back pain, may have been due to the local anesthetic with which the steroid was mixed in one study.18

These results support the individual perception of benefit of epidural steroids, expressed in terms of short-term symptomatic relief, a positive result in and of itself. However, the average effect difference (advantage of steroids over control treatment) was small, usually falling short of the value proposed as a clinically meaningful average difference18—15 mm on the 100 mm visual analogue pain scale. Other investigators have shown that, at the individual level, an optimal value for a clinically meaningful change on a 0 to 10 pain intensity scale is a 2-point absolute change (or a 33% relative change).23–25 However, the available studies did not express the magnitude of relief in terms of the percent of patients attaining a clinically meaningful response, and thus do not permit calculations of number of patients needed to treat in order to benefit one patient.

These results are consistent with the results of a study comparing 43 patients treated with epidural methylprednisolone applied during unilateral lumbar discectomy with matched historical controls that showed reduced need for narcotic and non-narcotic pain medications and muscle relaxants during the postoperative period, and shorter hospital stay in treated patients (an average of 2.72 days in treated patients vs 4.35 days in the untreated patients).26 Reported complications of epidural steroid injections are usually minor and transient: the most frequent is a transient headache. Reported major complications are rare (aseptic meningitis, arachnoiditis, bacterial meningitis, epidural abscess, and conus medullaris syndrome), and may result from subarachnoid, rather than epidural injection. There may be underreporting of complications, and the reported safety track record of experienced practitioners with large volumes may not reflect the track record of smaller volume or less experienced practitioners. These results do not answer most of the other questions listed in table 1. With regards to the specific question of avoidance of surgery, the data on face value are conflicting, with the better designed studies showing no benefit to epidural steroids. The data from the less well-designed studies are harder to interpret and generalize, as are data from uncontrolled clinical settings. The data do not permit inferring if surgery is avoided due to the treatment effect of injected steroids, due to placebo effect, or because the treatment “buys time” for a natural history of improvement.10 The data do not address how epidural steroid injections might compare to other treatment modalities and the role of patient and provider characteristics, including temperament and pain tolerance, in selecting among various treatment options. The recommendations gave greater weight to the data from the better designed studies, showing that epidural steroid injections did not result in less surgery.

However, an uncontrolled study27 with partial follow-up of treated patients has identified factors that predict poor outcome: 1) greater number of previous treatments for pain; 2) more medications taken; 3) pain not necessarily increased by activity; 4) pain increased by coughing. Factors that predict no benefit 1 year after treatment include 1) pain does not interfere with activities; 2) unemployment due to pain; 3) normal straight leg raising tests before treatment; 4) pain not decreased by medication. Better designed studies are needed to confirm these observations, and express them in contemporary terms of numbers needed to treat, relative to presence or absence of predictive factors for poor outcome.

Limitations.

This review is limited by its inability to compare all techniques and all treatment approaches. However, the findings in terms of pain relief and some of the secondary measures are similar for the earlier studies and for those that used fluoroscopy and transforaminal injections. This review did not assess issues of frequency of injection or dosage, and did not evaluate operator experience, which was implied to be high in all the published reports. The generalizability of the findings is limited. The focus on pain relief, guided by the chief indication for which epidural steroid injections are used, is a limitation, compared to using improvement of function as the primary outcome variable. However, it frames the subjective impressions of patients and providers in evidence-based terminology that may guide the future evaluation of this treatment modality.

Recommendations and conclusions.

  1. Epidural steroid injections may result in some improvement in radicular lumbosacral pain when determined between 2 and 6 weeks following the injection, compared to control treatment (Level C, Class I-III evidence). The average magnitude of effect is small, and the generalizability of the observation is limited by the small number of studies, limited to highly selected patient populations, the few techniques and doses studied, and variable comparison treatments.

  2. In general, epidural steroid injections for radicular lumbosacral pain have shown no impact on average impairment of function, on need for surgery, or on long-term pain relief beyond 3 months. Their routine use for these indications is not recommended (Level B, Class I-III evidence).

  3. Data on use of epidural steroid injections to treat cervical radicular pain are inadequate to make any recommendation (Level U).

Recommendations for future research.

  1. Further studies of the efficacy of epidural steroids for radicular lumbosacral pain should be well-designed, meeting the following criteria: a) clear case definition; b) clear measures of outcome using standardized tools, with function as the primary measure and clinically meaningful improvement in pain23–25 as a secondary measure; c) use of a control group (placebo or active); d) prospective design; e) randomization; f) double-blind study design, so that neither patient nor assessor of measure of outcome knows the treatment arm; or triple-blind, if physician administering the epidural steroids also does not know what treatment is administered; g) adequate power; and h) adequate statistical analysis.

  2. Studies of use of epidural steroids to treat radicular cervical pain or non-radicular low back or cervical pain should also be designed rigorously, meeting similar criteria.

  3. The principal questions to be answered are as follows:

    • (a)What is the degree of efficacy, expressed in terms of magnitude of effect, duration of effect, and percent of patients who achieve clinically meaningful improvement, in comparison to alternative treatments?

    • (b)Using a controlled design: are there predictors of lack of efficacy or poor efficacy? Consider studying first patients without putative predictors of poor efficacy.

    • (c)How many treatments are appropriate, and at what intervals?

    • (d)How frequent are complications, and what are they?

  4. Initially, it will be necessary to standardize some of the variables reflected in the questions in table 1, such as a specific technical approach, the minimal competency of the treating physician, and utilization of additional therapies.

  5. Subsequently, research can be directed to evaluate the role of these variables. In particular, different techniques will need to be assessed using standardized methodology.

Mission statement of TTA.

The Therapeutics and Technology Assessment Subcommittee (TTA) produces evidence-based statements that assess the safety, utility, and effectiveness of new, emerging, or established therapeutic agents or technologies in the field of neurology. These are developed through a rigorous process of defining the topic, evaluating and rating the quality of the evidence, and translating the conclusions of the evidence into practical recommendations that can help to guide the practice of Neurology.

It is not intended to include all possible proper methods of care for a particular neurologic problem or all legitimate criteria for choosing to use a specific procedure. Neither is it intended to exclude any reasonable alternative methodologies. The AAN recognizes that specific patient care decisions are the prerogative of the patient and the physician caring for the patient, based on all of the circumstances involved.

Conflict of interest statement.

The American Academy of Neurology is committed to producing independent, critical and truthful clinical practice guidelines (CPGs). Significant efforts are made to minimize the potential for conflicts of interest to influence the recommendations of this CPG. To the extent possible, the AAN keeps separate those who have a financial stake in the success or failure of the products appraised in the CPGs and the developers of the guidelines. Conflict of interest forms were obtained from all authors and reviewed by an oversight committee prior to project initiation. AAN limits the participation of authors with substantial conflicts of interest. The AAN forbids commercial participation in, or funding of, guideline projects. Drafts of the guideline have been reviewed by at least three AAN committees, a network of neurologists, Neurology peer reviewers, and representatives from related fields.
