Steroids for Sciatica Pain: More Trouble Than They're Worth
By Deborah Pate, DC, DACBR
Use of epidural steroid injections has increased dramatically in recent years, despite the fact that studies have failed to demonstrate evidence this procedure is clinically helpful (while other studies suggest it may actually be dangerous).
Considering that lack of evidence – not to mention the terrible 2012 outbreak of fungal meningitis / infections caused by contaminated vials used for epidural corticosteroid injections – it is prudent at least to take a critical look at this procedure as it relates to sciatica pain
or pain affecting the sciatic nerve, which extends from the lower back down the back of each leg.
Small Relief, Big Potential Side Effects
In a recent meta-analysis of 23 randomized trials involving more than 2,000 patients in which epidural steroid injections were compared with placebo for sciatica pain, epidural steroid injections produced small, statistically insignificant
short-term improvements in leg pain and disability (but not less back pain) compared to placebo. This improvement also was only over a short period of time – two weeks to three months. Beyond 12 months, there was no significant difference between groups.
Besides infection, there are other side effects associated with epidural steroid injections: bleeding, nerve damage and dural puncture. Then there are side effects associated with the steroid medication, which include the following: a transient decrease in immunity, high blood sugar, stomach ulcers, cataracts and increased risk of fracture.
|Tainted Steroid Injections: The Framingham OutbreakIn September 2012, the CDC and the FDA began investigating a multistate outbreak of fungal meningitis and other infections among patients who had received contaminated steroid injections. The contaminated vials were tracked back to a New England compounding center in Framingham, Mass. The cases included fungal meningitis; localized spinal or paraspinal infections, including epidural abscess, basilar stroke, vertebral osteomeylitis and arachnoiditis; and infections associated with injection in a peripheral joint space such as the knee, shoulder or ankle. Ultimately, the outbreak resulted in 751 cases and 64 deaths in more than 20 states.|
This last complication is certainly not emphasized in clinical circles. Therapeutic steroids may reduce sciatica pain, however the use of steroid injections seem to promote deterioration of skeletal quality, which is not surprising since other forms of steroid medication have long been associated with osteoporosis.
A retrospective study published in the Journal of Bone and Joint Surgery
looked at lumbar epidural steroid injection (LESI), and the potential impact on bone fragility and vertebral fractures (spinal fractures). Researchers identified a total of 50,345 patients who had medical diagnosis codes involving the spine; within that group, a total of 3,415 patients had received at least one LESI.
Three thousand patients were randomly selected from the 3,415 injected population and 3,000 additional patients were selected from the non-injected group as a control group. There was no significant difference between the injected and non-injected groups with respect to age, sex, race, hyperthyroidism or corticosteroid use.
When incidence of vertebral fractures was assessed, researchers discovered that an increasing number of injections was associated with an increasing likelihood of fractures, and each successive injection increased the risk of spinal fracture by 21 percent. Based on this evidence, LESIs clearly exacerbate skeletal fragility. They promote deterioration of skeletal quality similar to the use of exogenous steroids, which is the leading cause of secondary osteoporosis. In fact, the rate of vertebral fracture following epidural steroid injections may be underestimated.
Both European and American guidelines, based on systemic reviews, conclude that epidural corticosteroid injections may offer temporary relief of sciatica, but do not reduce the rate of subsequent surgery. This conclusion is based on multiple randomized trials comparing epidural steroid injections with placebo injections, and monitoring of subsequent surgery rates. Facet joint injections with corticosteroids seem no more effective than saline injections.
Rising Costs, Limited Benefits
Despite the limited benefits of epidural injections, Medicare claims show a 271 percent increase during a recent seven-year interval. Earlier Medicare claims analyses also demonstrated rapid increases in spinal injection rates. For patients with axial back pain without sciatica, there is no evidence of benefit from spinal injections; however, many injections given to patients in the Medicare population seem to be for axial back pain alone.
Charges per injection have risen 100 percent during the past decade (after inflation), and the combination of increasing rates and charges has resulted in a 629 percent increase in fees for spinal injections. Yet during this time, the Medicare population increased by only 12 percent.
It all begs the question: Why such a huge increase in the use of a procedure that has limited benefit?
- Epidural steroid injections have little clinical benefit (short or long term) and are associated with significant risks.
- Steroid injections cause deterioration of bone quality, elevating the risk of spinal fracture.
- Use of epidural steroid injections has increased dramatically despite lack of evidence to justify the procedure.
