Back Pain Doctor in Manchester, MO

MANCHESTER, MISSOURI

Pain that returns two or three years after a successful fusion is usually not a failure of the operation. It is the segment above it taking load it was never designed to carry, and it has its own diagnosis and its own treatment.

Getting here from Manchester

Manchester is roughly 15.1 miles from the Natural Bridge Road office, about 24 minutes via I‑270 south and Manchester Road. Patients coming from here frequently arrive with a surgical history, and the first job is establishing whether the current pain is the old problem, a new problem, or a consequence of the repair.

Adjacent segment disease is a mechanical consequence, not a mistake

A lumbar fusion eliminates motion at the fused levels. That motion does not disappear from the spine; it is redistributed to the segments immediately above and below. Those segments then experience increased range, increased disc pressure and increased facet loading for every subsequent year.

Over time a proportion of fused patients develop degenerative change at the adjacent level, and a smaller proportion develop symptoms from it. Reported rates vary widely depending on how it is defined, but the phenomenon itself is not in dispute.

The distinction that matters clinically is between radiographic change, which is common and often silent, and symptomatic disease, which is less common and treatable. Finding degeneration above a fusion on imaging does not by itself explain a patient’s pain.

Sorting out what the pain actually is

Post‑surgical back pain has a short list of explanations, and they are separable:

  • Adjacent segment facet pain, typically axial, worse with extension and rotation, confirmable with a diagnostic block
  • Adjacent segment stenosis or foraminal narrowing, producing new leg symptoms in a distribution one level above the old one
  • Sacroiliac joint pain, which becomes markedly more common after lumbosacral fusion because the joint absorbs transferred load
  • Persistent radicular pain from the original nerve injury, which may not resolve even when the compression was successfully relieved
  • Hardware‑related pain or, uncommonly, a pseudarthrosis where the fusion did not consolidate

Failed back surgery covers the whole differential, and it is worth reading before assuming the operation failed.

The sacroiliac joint after a fusion

This is the one most often missed. Fusing to the sacrum transfers motion directly to the sacroiliac joints, and new pain below the belt line after a lumbosacral fusion has a high probability of being sacroiliac in origin.

It is missed because the imaging attention stays on the lumbar spine and the hardware, and because sacroiliac pain refers into the buttock and thigh in a way that reads as recurrent radiculopathy.

The examination settles it in a few minutes. Sacroiliac joint pain describes the provocation testing, and sacroiliac joint injection covers the confirmatory block.

What can be done without another operation

A good deal, and this is worth saying because the assumption after a fusion is often that the only remaining option is more surgery.

Confirmed adjacent segment facet pain responds to medial branch blocks and, when they are positive, to radiofrequency ablation. Confirmed sacroiliac pain responds to targeted injection and lateral branch treatment. Radicular pain from adjacent segment stenosis responds to a level‑specific epidural steroid injection.

Where the pain is genuinely refractory and a structural target cannot be found, spinal cord stimulation has its strongest evidence base in exactly this population — persistent radicular pain after lumbar surgery. It is not a first option and it is not offered as one.

When more surgery is the right call

Extending a fusion to the adjacent level is sometimes correct. The indications are the same as they ever were: a clear structural lesion, a clinical picture that matches it, meaningful functional limitation, and conservative and interventional options that have genuinely been tried.

It is a worse call when it is proposed to treat axial pain with no confirmed generator, because extending a fusion also extends the problem upward — the new top level then becomes the new adjacent segment.

That is the conversation worth having before agreeing. Before you agree to back surgery sets out the questions, and they apply with more force the second time than the first.

What Manchester patients ask

Does this mean my fusion failed?

Usually not. A fusion that relieved the original symptom and consolidated properly did its job. Pain at a different level years later is a consequence of altered mechanics, which is a different thing from a failed operation. The distinction matters because the treatments are different.

Should I go back to my surgeon?

It is reasonable to, and we will coordinate with them. What a pain physician adds is the diagnostic work that establishes which structure is now generating the pain, which is often the missing piece before a surgical decision can sensibly be made.

How long after a fusion does this usually show up?

Most commonly a few years out, though the range is wide. Onset within weeks of surgery points at something different — usually the original problem or a complication rather than adjacent segment change.

I have had pain ever since the operation, not years later?

That is a different pattern and a different differential. Persistent pain from the start suggests the original diagnosis, a nerve injury that has not recovered, or a problem with the surgery itself. Failed back surgery covers each.
