Is Adult Scoliosis Surgery Worth It?

What does "success" mean after scoliosis surgery?

Researchers measure success with patient questionnaires that cover pain, function, self-image, and mental health. A "meaningful" improvement is the smallest change patients themselves notice as better. In a large prospective study followed for about four years, average back pain fell from 7.1 to 3.8 on a 10-point scale. In the same study, satisfaction scores rose sharply. Self-image, meaning how people feel about their appearance and posture, usually improves the most. Overall, about 86–88% of adult deformity patients report being satisfied.

How does surgery compare with non-surgical treatment?

The best data come from the Adult Symptomatic Lumbar Scoliosis (ASLS) study, which was funded by the NIH. When patients were analyzed by the treatment they actually received, those who had surgery improved far more in disability and quality-of-life scores. Patients treated without surgery, on average, did not improve much. The difference held at eight years, with no sign of fading.

The study investigators gave practical advice. If you are satisfied with your current spine health, non-surgical care makes sense, but you should not expect much improvement. If you are not satisfied and want improvement, surgery is generally preferred.

How common are complications?

Complications are common, and it is important to understand them before deciding. In a prospective multicenter study, about 70% of patients had at least one complication within two years. That count includes minor problems such as a urinary infection or short-term anemia. About 28% needed at least one more operation. A 2024 analysis of nearly 1,000 patients found that about 20% had a complication that required reoperation. The encouraging news is that major complication and reoperation rates have fallen by roughly half over the past decade.

What is the risk of paralysis?

Permanent, complete paralysis is rare. Some nerve-related problem is not rare. In the Scoliosis Research Society's large surgeon-reported database, about 1% of patients had a new nerve deficit right after surgery. Prospective studies that look more closely report nerve complications in 10–17% of patients. These complications are most often weakness or numbness in one leg. In the most complex operations, about 23% of patients had some decline in leg strength. Most of those patients recovered, and about 9% still had some weakness at five years.

What is the risk of death?

For thoracolumbar deformity surgery, the risk of death within 30 days is about 0.1–0.6%, and within 90 days about 0.3–0.9%. In the Scoliosis Research Society's database of more than 100,000 spine operations, death occurred in about 2 per 1,000 scoliosis cases. Most deaths were from heart or lung problems or infection. Risk is higher with older age and serious medical conditions.

What about complications later in life?

Some problems show up months or years later. Examples include a forward bend just above the fusion (proximal junctional kyphosis), broken rods, and wear at the level next to the fusion. In one study with at least five years of follow-up, most adverse events occurred in the first two years, and about 19% of patients had a new event after that. See Problems after spinal fusion.

"Scoliosis surgery ruined my life" — why do some people say this?

Some patients do have a difficult course. Causes include a serious complication, repeated revisions, or pain that does not improve. Careful patient selection lowers these risks. So do treating weak bones before surgery, planning alignment around each patient's pelvic anatomy, and choosing a surgeon and center with deformity experience. An honest conversation about your specific risk matters more than average numbers.

Who is most likely to benefit?

The people most likely to benefit have significant disability, back or leg pain, or posture problems that persist despite good non-surgical care, and are healthy enough for a major operation. Age alone is not a barrier. In a multicenter study of patients aged 60 and older, the share with severe disability fell from 59% before surgery to 20% at two years, and the gains held at five years.

Questions to ask your surgeon

• What is my personal risk of complications and reoperation?
• What alignment goals are you planning for my anatomy?
• Should my bone density be checked or treated first?
• What happens if I wait?

When to see a specialist. If you are weighing surgery or want a second opinion, request an appointment.
