Epidural Steroid Injections


Knee Pain Relief with Prolotherapy

Danielle R. Steilen, MMS, PA-C
The long-term and the short-term

A recent study from John Hopkins suggested that 75% of patients they monitored who were treated with epidural steroids reported 50 percent or greater leg pain relief and felt better overall after one month compared to those who received saline (50 percent) or etanercept (acting as an anti-inflammatory 42 percent).

On a pain scale of 0 to 10, with 10 denoting the worst pain, those who received steroids reported, at one month, an average pain score of 2.1 compared with 3.6 in the etanercept group and 3.8 in the group injected with saline.

Those in the steroid group also reported lower levels of disability (21 percent) than those in the saline group (29 percent) or etanercept group (38 percent).

Sounds good for the epidural against saline or antin-inflammatory – BUT  after six months, however, slightly more patients in the saline (40 percent) and etanercept (38 percent) groups had a positive outcome than those in the steroid group (29 percent). 1

Saline better than steroid in the long-run?

Epidural steroid injections are one option commonly presented to people with neck pain, thoracic pain, and low back pain. The goal of this injection is pain relief through a reduction of inflammation and swelling in the epidural space. The injection consists of inserting a needle into the epidural space of the spine and injecting a long lasting steroid.

  • Many health professionals agree that the results are temporary and have no long-lasting effect.

This research supported a recently published work in the British Medical Journal  that looked at the effectiveness of caudal epidural steroid or saline injections which are often used for chronic lumbar radiculopathy. They looked at the patients’ reponses at 6 weeks, 12 weeks, and 52 weeks. It was a multi-centered trial, blinded, randomized and controlled.

They found no statistical or clinical difference between the groups over time.  At the one year follow-up after epidural steroid injection, pain and disability improvement was reported at 36% and 43% of patients respectively. However, this was no different from the natural recovery without treatment.2

Painkillers and bone loss

Short term relief, necessity for repeated injections with diminishing results?

  • Worse, recent research says epidural steroids for back pain robs postmenopausal women of bone.

Research suggests that a single epidural steroid injection in postmenopausal women adversely affects bone mineral density of the hip. Enough so that  doctors should be considering options  when contemplating treatment for radiculopathy.

The resulting decrease in bone mineral density, while slight, suggests that epidural steroid injections should be used with caution in those at a risk for fracture.3

Therapy with glucocorticoids often results in bone loss and glucocorticoid-induced osteoporosis

Other researchers, however, disagree. While they agree that corticosteroids often result in bone loss and corticosteroid-induced osteoporosis, they say it has nothing to do with bone mineral density because no link has been made between epidural steroid injection and bone mineral density. Further smaller doses are okay. Here’s what they say:

“These data suggest that epidural steroid injection using triamcinolone (over 200 mg) for a period of one year will have a negative effect on bone mineral density in postmenopausal women treated for lower back pain. However, ESI therapy using a maximum cumulative triamcinolone dose of 200 mg in one year would be a safe treatment method with no significant impact on BMD.”

[Fortunately these researchers recognized their limitations]: First, this study is limited by the fact that it was retrospective. Second, this study did not consider the use of ESI with high-dose corticosteroids. “Third, our study did not include any long-term assessments of the effects of ESI on BMD.” 4

So the findings do not include long-term high dose steroid use. After further review a similar group of researchers came back and said. “Therapy with glucocorticoids often results in bone loss and glucocorticoid-induced osteoporosis. However, the relationship between epidural steroid injection (ESI), bone mineral density (BMD), and vertebral fracture remains to be determined.” Confused? Read the research, it wasn’t the steroids – it was old age:

  • “Older age and lower bone mineral density were associated with osteoporotic fracture in postmenopausal women treated for low back pain with epidural steroid injection. The epidural steroid injections were not associated with low bone mineral density or fracture.”

Again, the limitations were that this research was not valid for patients who received high-dose corticosteroids, that study group was too small to provide assessment.5

Prolotherapy for Back Pain

Temporary pain relief is not what pain patients should be seeking. Permanent healing and pain relief should be the goal. Maybe pain patients don’t believe there is a cure for their pain, so they seek as many pain relief options as possible. The problem is that many pain relief treatments include steroids and anti-inflammatory agents that can make the injury even worse. As the injury gets worse, a person is forced to look for stronger and more complex pain relief. It’s a vicuous cycle.

Prolotherapy is the opposite of epidural steroid injections. Prolotherapy creates inflammation to bring blood flow and healing factors to the injured tissue. Any neck or back pain that is related to joint degeneration or ligament injury can be treated effectively with Prolotherapy.
