When most people hear the word "scoliosis," they think of adolescents being screened at school — a nurse asking them to bend forward while she checks for an uneven rib cage. That is one form of scoliosis, but it is not the one I treat most often in my practice. The scoliosis I see is the adult version, and it is far more common than most patients realize. It can cause debilitating pain, progressive imbalance, and a slow but relentless decline in the ability to stand upright and walk comfortably.
If you have been told you have adult scoliosis, or if you are dealing with worsening back pain, leg symptoms, and difficulty standing up straight, this article will walk you through what is happening in your spine, why it matters, and what can be done about it.
What Is Adult Scoliosis?
Scoliosis is a lateral curvature of the spine — meaning the spine curves to the side when viewed from behind. In a healthy spine, the vertebrae stack in a relatively straight column when seen from the back. In scoliosis, that column develops a curve, typically in the shape of a "C" or an "S."
Adult scoliosis generally falls into two categories:
Degenerative scoliosis (also called de novo scoliosis) develops later in life, usually after age 50. It is caused by the same wear-and-tear process that leads to arthritis throughout the body. As the discs between your vertebrae lose height and the facet joints develop arthritis, the spine can begin to shift and tilt to one side. Think of it like a building settling unevenly on a deteriorating foundation — the structure is sound at the top, but the base is giving way.
Progressive adolescent scoliosis is a curve that was present in childhood but was small enough that it did not require treatment at the time. In many patients, these curves remain stable for decades and then begin to progress again in the fifties and sixties as the spine undergoes degenerative changes. The curve that was 20 degrees at age 16 may quietly become 45 degrees by age 60.
In my experience, most adult scoliosis patients are not aware that they have a curve until something starts hurting. The curve itself is rarely the first thing they notice — it is the pain, the imbalance, or the leg symptoms that bring them to my office.
What Does Adult Scoliosis Feel Like?
Adult scoliosis does not always cause symptoms. Some patients have significant curves on X-ray but feel perfectly fine. The decision to treat scoliosis is always based on symptoms, not on the number of degrees measured on an X-ray.
When adult scoliosis does become symptomatic, the most common complaints include:
- Low back pain — typically worse with standing and walking, and relieved by sitting or leaning forward. This is the most common reason patients seek evaluation.
- Leg pain, numbness, or weakness — the curve often causes spinal stenosis (narrowing of the spinal canal) on the concave side of the curve, which can compress the nerves and produce symptoms similar to a pinched nerve.
- Progressive imbalance — patients notice they are leaning to one side or pitching forward. They may describe feeling like they are "falling over" or needing to use their arms to push themselves upright.
- Difficulty standing upright for prolonged periods — standing in line at the grocery store, walking through a museum, or attending a grandchild's sporting event becomes increasingly painful.
- Cosmetic concerns — some patients notice that their waistline is uneven, one hip appears higher than the other, or their ribcage is more prominent on one side.
The natural history of adult degenerative scoliosis is slow progression. Curves tend to increase by one to two degrees per year on average, and once they exceed 30 degrees, they are more likely to continue progressing. This does not mean that every patient with a 30-degree curve will need surgery, but it does mean that monitoring is important.
How Is Adult Scoliosis Diagnosed?
The workup for adult scoliosis starts with a thorough history and physical examination. I pay close attention to how you stand, how your shoulders and pelvis are aligned, and whether you are leaning forward or to the side. A simple test — asking you to bend forward — can reveal rotational deformity in the ribcage or lumbar spine.
The most important imaging study is a set of standing full-length X-rays — taken from the front and the side while you are standing upright. These films allow me to measure the curve, assess your overall spinal balance, and evaluate your sagittal alignment, which describes whether your spine is maintaining its normal front-to-back curvature. Sagittal alignment is at least as important as the side-to-side curve when it comes to predicting symptoms and planning treatment.
An MRI is typically ordered to evaluate the spinal canal and nerve roots, particularly if you are experiencing leg pain or neurological symptoms. The MRI shows us whether the stenosis is significant enough to explain your symptoms and helps guide surgical planning if it comes to that.
In some cases, I may also order a CT scan to get a more detailed look at the bony anatomy, particularly if surgery is being considered. This helps with preoperative planning, including the placement of screws and the extent of correction that can be safely achieved.
Conservative Treatment Options
Not every patient with adult scoliosis needs surgery. In fact, the majority of patients I see with adult scoliosis are managed successfully without an operation, at least initially. The goal of conservative treatment is to control pain, maintain function, and slow the progression of symptoms.
Physical therapy is the cornerstone of non-surgical treatment. A well-designed therapy program focuses on core strengthening, flexibility, and postural awareness. Strong core muscles act like an internal brace for the spine, providing support and reducing the load on the arthritic joints and deteriorating discs. I typically recommend therapy programs that emphasize stabilization exercises rather than aggressive stretching or manipulation.
Anti-inflammatory medications — both over-the-counter options like ibuprofen and naproxen, and prescription alternatives — can help manage the inflammatory component of pain. Acetaminophen can be used for pain relief as well, though it does not address inflammation.
Epidural steroid injections can be useful when spinal stenosis is contributing to leg pain. These injections deliver anti-inflammatory medication directly to the area of nerve compression and can provide meaningful relief for weeks to months. They do not change the underlying curve, but they can significantly improve quality of life and help patients remain active.
Activity modification is practical but important. Learning which positions and activities aggravate your symptoms — and which ones relieve them — is a key part of managing adult scoliosis over the long term.
I tell my patients that conservative treatment is not about "fixing" the curve. The curve is there, and it is not going away with therapy or injections. The goal is to manage the symptoms well enough that you can live the life you want to live. For many patients, that is entirely achievable without surgery.
When Surgery Becomes the Right Choice
Surgery for adult scoliosis is not about making an X-ray look better. It is about restoring function and relieving pain that has not responded to appropriate conservative care. I consider surgery when:
- Pain and functional limitations persist despite at least three to six months of dedicated conservative treatment
- Neurological symptoms — leg weakness, progressive numbness, or difficulty walking — are worsening
- The curve is progressing and causing increasing imbalance
- Quality of life has deteriorated to the point where you cannot do the things that matter to you
The decision to proceed with surgery for adult scoliosis is never taken lightly. These are among the most complex operations in spine surgery, and I spend considerable time with each patient discussing the goals, the risks, and what realistic expectations should look like.
What Does Surgery Involve?
Surgery for adult scoliosis is tailored to each patient's specific anatomy, symptoms, and goals. There is no single operation that fits every situation. The surgical plan depends on the size and location of the curve, the degree of stenosis, the patient's sagittal balance, and their overall health.
Decompression Alone
In some patients — particularly those with a relatively stable curve but significant stenosis causing leg symptoms — a targeted decompression (removing bone and ligament to open up the spinal canal) may be sufficient. This is a smaller operation with a shorter recovery, but it is only appropriate when the curve itself is not the primary driver of symptoms and is not at significant risk of progressing.
Decompression and Fusion
More commonly, surgery for adult scoliosis involves both decompression (to relieve nerve compression) and fusion (to stabilize the spine and correct the deformity). Fusion involves placing screws into the vertebrae and connecting them with rods. The surgeon then corrects the curve to the degree that is safe and appropriate, restoring alignment and balance.
The length of the fusion — how many vertebrae are included — depends on the extent of the curve and the patient's overall balance. Some patients require a fusion of just a few segments, while others need a longer construct that extends from the upper thoracic spine down to the pelvis.
Osteotomies for Severe Deformity
In patients with rigid, severe curves or significant sagittal imbalance (leaning forward), the surgeon may need to perform osteotomies — controlled cuts in the bone — to allow the spine to be straightened and rebalanced. These are more complex procedures, but they can produce dramatic improvements in alignment and function for patients with advanced deformity.
Interbody Fusion
In many adult scoliosis cases, I use interbody cages — structural devices placed in the disc space between vertebrae — to restore disc height, improve alignment, and promote a solid fusion. Modern 3D-printed titanium cages offer excellent bone ingrowth properties and can be sized precisely to fit each patient's anatomy.
What Results Can I Expect?
Adult scoliosis surgery is a major undertaking, and I am always transparent with my patients about what it involves. Recovery is measured in months, not weeks. Most patients spend several days in the hospital after surgery and then transition to a rehabilitation program.
The first six weeks focus on healing and basic mobility — getting up, walking, and gradually increasing activity. From six weeks to three months, patients typically progress through physical therapy and begin returning to more normal daily activities. Full recovery — including the spine achieving a solid fusion — generally takes six to twelve months.
The outcomes, however, can be life-changing. Research consistently shows that patients who undergo surgery for adult scoliosis experience significant improvements in pain, function, and quality of life. The ability to stand upright, walk without pain, and return to activities that had become impossible is profoundly meaningful for patients who have been living with progressive deformity.
I always tell patients that the goal of surgery is not a perfect X-ray — it is a better life. We want you standing straighter, hurting less, and doing more of the things that matter to you. That is how I measure success.
That said, adult scoliosis surgery carries real risks, including infection, blood loss, nerve injury, hardware complications, and the possibility that additional surgery may be needed in the future. These risks are higher than in simpler spine operations, and they increase with patient age and medical comorbidities. A thorough preoperative evaluation — including medical optimization, nutritional assessment, and bone density testing — is essential to achieving the best possible outcome.
The Bottom Line
Adult scoliosis is a common and often underrecognized cause of back pain, leg symptoms, and progressive spinal imbalance. It does not always require surgery, and many patients do well with conservative measures including physical therapy, injections, and activity modification. When conservative treatment is no longer enough, surgical options exist that can meaningfully restore alignment, relieve pain, and improve quality of life — but these are complex operations that require careful patient selection and thorough planning.
If you are dealing with worsening back pain, difficulty standing upright, or leg symptoms that are limiting your daily activities, I would encourage you to schedule a consultation. Adult scoliosis is a condition I treat regularly, and I can help you understand your options and make the decision that is right for you.
