Can You Spot 3 Common Signs of “ESI Exhaustion”?

Author— Anjum Bux, MD Published December 10, 2021

If your lumbar spinal stenosis (LSS) treatment algorithm relies on serial epidural steroid injections (ESIs) to relieve chronic lower back and leg pain associated with neurogenic claudication, data supports a different approach—­performing the mild® Procedure immediately upon diagnosis of LSS or moving to mild® after the first ESI fails may help your patients avoid “ESI Exhaustion.”

We already know that epidurals are not capable of “curing” neurogenic claudication, a major root cause of lumbar spinal stenosis which is present in 94% of patients. The steroids in the injection are believed to reduce inflammation to relieve pain; however, injections are only treating the symptoms of LSS. For long lasting relief, debulking the ligament is required. Injections results typically last less than six months. To provide ongoing relief, patients often require 2-3 injections on average per year.

Due to the temporary nature of epidural steroid injection relief, and the requirement for repeat injections, many practices encounter patients with what is increasingly becoming known as “ESI Exhaustion.” ESI Exhaustion can be spotted in patients at any stage of LSS treatment or stenosis severity. Once you start recognizing the signs of ESI Exhaustion in your lumbar spinal stenosis patients, you’ll see why so many leading clinicians are moving to mild® earlier in their treatment algorithm.

ESI Exhaustion Sign #1: Feelings of Hopelessness

“I went through three rounds of injections. I had heard ‘we’ve had pretty good results with this.’ But when you go through so many, it’s like ‘okay, I’ve heard this one before.’” -Ronnie, mild® Patient

When patients experience short-term relief for a condition as challenging as LSS, it can be easy for them to become frustrated and lose hope. Patients can become tired from needing to return for repeat injections. Other patients may start to feel hopeless if the injection is not effective or if it is only effective for a very short time. It’s important to remember that LSS patients often experience debilitating pain and loss of mobility that can have a devastating impact on their quality of life.

To help your patients remain optimistic and aligned to your treatment plan, educate your new and existing LSS patients about your treatment options early. Make sure they know that there is a procedure that offers the safety equivalence of an ESI, but with lasting results. If you are starting their treatment plan with a single epidural, inform them about the mild® Procedure during that first visit, so they know that if the ESI is not effective, there are other options that can help restore mobility by addressing a major root cause of LSS.

ESI Exhaustion Sign #2: Decreasing Durability of Relief

“The first epidural lasted about three months and then the pain was back. I went for the second epidural, and it didn’t last two weeks. My physician said, ‘Well you can have one more’ I said, ‘No, I’m finished with them.’”
-Lynn, mild® Patient

One of the more common questions patients have about a steroid injection is “how long will the results last?” Unfortunately, with ESIs, efficacy can vary by patient, and it can be difficult to predict the degree of relief or durability of effect for each. While studies have shown pain relief for up to six months in some lumbar spinal stenosis patients receiving steroid injections, other studies have demonstrated limited effectiveness.

Even more vexing for some patients is that the durability of effect of an initial ESI may not be experienced with subsequent injections. To achieve effectiveness over two to three years, five or more injections per year may be required.

Rather than offering patients a series of injection after injection with short-term results, move to mild® after the first ESI fails. The mild® Procedure offers a clinically proven safety profile equivalent to ESIs, but with lasting results. A 5-year study completed by the Cleveland Clinic showed that mild® helped 88% of patients avoid back surgery for at least 5 years while providing lasting relief.

ESI Exhaustion Sign #3: Solution Shopping

“The orthopedic surgeon gave me two options, back surgery with metal plates or more shots. I wanted something simple that would make me better.” -Faye, mild® Patient

If patients are dissatisfied with their results and feel they’ve run out of options in your practice, they may start to search for another solution. By offering mild® as an early intervention, you can avoid losing patients and actually increase productivity in your practice. Upon diagnosis of LSS, inform patients that you offer mild®, a minimally invasive treatment option that offers durable relief.

If you have already treated a patient with an ESI and it failed, or the patient received an injection in another practice, there is no reason to continue to offer another injection. Most patients I’ve seen are excited to learn that there is another option. Moving to mild® gives them new hope in finding lasting relief.

How to Avoid ESI Exhaustion? Move to mild®.

While “ESI Exhaustion” is highly common among LSS patients, it is also completely avoidable. Recognizing that serial injections are often the standard of care when conservative care methods like exercise and physical therapy have failed to provide relief, we published a study in Pain Management that evaluated whether LSS patients benefit from multiple ESIs prior to mild®.

The article, ‘Minimally invasive direct decompression for lumbar spinal stenosis: impact of multiple prior epidural steroid injections’ compares outcomes between 145 patients receiving either 0/1 injections or 2+ injections at 6 centers in the United States. In reviewing results between the two groups, we concluded that there is no benefit to performing multiple epidural steroid injections before the mild® Procedure and that doing so delays the patient from receiving a longer-lasting, more effective mild® treatment.

Based on this study and other favorable data, we recommend performing the mild® Procedure for lumbar spinal stenosis patients immediately upon diagnosis of neurogenic claudication with hypertrophic ligamentum flavum, or after the first ESI fails.
