How To Treat Different Stages Of Spinal Stenosis

Spinal stenosis is a topic we touch on pretty frequently on our blog because it’s one of the more common conditions we help patients overcome. In a patient with spinal stenosis, one or more of the openings in the spine through which nerves and other key structures pass begins to narrow. This narrowing compresses these structures, leading to pain, numbness and a host of other symptoms.
As you can imagine, these natural spinal openings don’t narrow overnight. They typically set in very slowly over time as a result of natural aging, injury or mechanical factors like repetitive strain or poor posture habits. Most cases of spinal stenosis are categorized into one of four different categories based on the progression of the condition, and in today’s blog, we explore how these different stages of spinal stenosis are commonly treated.
The Stages Of Spinal Stenosis And Treatment Options
Let’s break down each stage of spinal stenosis and how a spine specialist would likely attack the problem.
- Stage 1 – Stage one is the lowest form of the condition, typically classified as mild spinal stenosis. Symptoms are typically mild and may only develop in certain instances, like when standing up first thing in the morning or after a long day sitting in your office chair. Even though symptoms aren’t all that bad, this is also the stage where the condition is most responsive to treatment, so a few adjustments to your daily life can resolve the narrowing and have your spine feeling back to normal.
- Treatment Plan – Posture improvements to limit additional strain on the affected area, physical therapy and stretching techniques to limit nerve compression and strengthen supportive structures, and limiting time in positions that tend to exacerbate symptoms are all effective options. Anti-inflammatory medications can also prove useful, but should be paired with proactive interventions.
- Stage 2 – The second stage is classified as moderate spinal stenosis, and on imaging the doctor will notice that the canal opening has narrowed by 25-50%. This reduction will almost always lead to the onset of symptoms, even if they are only mild or moderate in nature. You may have some daily limitations as a result of your discomfort or find it hard to sit or sleep for extended periods without discomfort.
- Treatment Plan – The treatment plan is essentially identical to the above stage, and it’s still quite effective since too many patients don’t begin treating the condition in the first stage. Physical therapy, posture improvements, activity modification and anti-inflammatories will all help manage the condition. Dietary improvements and weight loss can also be helpful for cases of lumbar spinal stenosis where weight is adding to the stress on affected structures in the lower spine.
- Stage 3 – Spinal stenosis is considered severe when it reaches the third stage, which is classified as a 50-75% reduction in normal canal spacing. Symptoms are obvious and can be both painful and debilitating. Daily activities are impacted and symptoms may be chronic or persistent.
- Treatment Plan – If this is the first time you’re seeking professional treatment, they may recommend a more aggressive non-operative care plan involving physical therapy, activity modification, posture fixes and medications to manage discomfort and inflammation. If you’ve already tried these techniques for weeks, more hands-on care may be recommended, like a corticosteroid injection or a minimally invasive decompressive surgery.
- Stage 4 – Do what you can to avoid reaching this stage, typically classified as end stage spinal stenosis. You’ll have more than 75% canal narrowing, with major symptoms that can include loss of bladder or bowel function depending on which nerves are impacted. Pain and movement restrictions are also severe by this point, and you’re incapable of performing some daily tasks as a result of the condition.
- Treatment Plan – Surgery is typically the standard course of care for a patient with end stage spinal stenosis. Operative care is usually effective, but success is dependent on a number of factors, including the extent of the narrowing and nerve damage, so it’s best not to let the condition get to this point before meeting with a professional.
