Pressure on the spinal cord itself, rather than on a nerve leaving it. Where along the spine it happens changes the symptoms completely — and the cord does not run the whole way down.
The spinal cord is the main cable between the brain and the body, carrying every signal in both directions. It runs inside a bony canal formed by the vertebrae, with only a small margin of space around it.
Myelopathy is what happens when that margin disappears and something presses on the cord — degenerative wear, a disc herniation, a narrow canal, a tumour, or injury. Because the cord carries signals for everything below the level of compression, the effects are felt in the limbs and in balance rather than only at the site.
The two words are easily confused and the distinction is important.
They arise from the same degenerative changes and often coexist. The radiculopathy is what people notice, because it hurts. The myelopathy is what matters more.
Myelopathy is named for the level of the spine affected, and the level determines the symptoms entirely.
The neck · by far the commonest
Compression in the neck affects everything below it, which is almost the whole body. Clumsy hands, difficulty with buttons, deteriorating handwriting, unsteady walking — frequently with no neck pain at all.
Most often from cervical spondylosis, the ordinary age-related wear of the neck. This is the form most people mean when they say myelopathy.
The mid and upper back · uncommon
The thoracic canal is naturally narrow and the segment barely moves, so degenerative compression here is much rarer. When it occurs it is more often from a disc herniation, a thickened ligament, a tumour or a fracture.
Because the arms are supplied above this level, the hands are spared. Symptoms appear in the legs and trunk — leg weakness, stiffness, unsteady walking, sometimes a band-like sensation around the chest or abdomen.
The lumbar spine · a different problem
The spinal cord ends at around the first or second lumbar vertebra. Below that point there is no cord to compress — the canal contains a bundle of individual nerve roots called the cauda equina, the horse's tail.
So "lumbar myelopathy" is not a condition. Compression in the lower back affects nerve roots, which produces sciatica, the symptoms of spinal stenosis, or in severe cases cauda equina syndrome.
The distinction is not pedantry. Root compression and cord compression behave differently, are examined for differently, and carry different urgency.
What you notice depends on the level, but certain features point to the cord rather than a root:
Pain may be present, but its absence means very little here — which is precisely why myelopathy is missed.
Most myelopathy develops over months or years. Where it changes rapidly, the cord is under pressure that should be relieved without delay.

If we are closed, go to an emergency department. We are shut on Sundays and after 1pm on Saturdays. A cord under rapidly increasing pressure should not wait for Monday.

The honest framing matters here, because the goal is not what most people assume.
Monitoring is reasonable — regular review, repeat examination, imaging if things change. Physiotherapy and activity modification help function, but it is important to be clear that they do not relieve the compression.
Decompression halts the progression. It does not reliably reverse damage already done. Some people improve considerably. Many stabilise. The reliable benefit is preventing further loss.
That is why timing carries more weight in this condition than in most. Operating early protects function that still works; operating late protects what is left.
Depends on the level, how many segments are involved and the alignment of the spine:
Both approaches are performed here. Which fits is a discussion rather than a default.
No. The spinal cord ends around the first or second lumbar vertebra, so below that there is no cord to compress. Problems there affect nerve roots instead — producing sciatica, the symptoms of spinal stenosis, or cauda equina syndrome. You may see "lumbar myelopathy" written, but it is not an accurate term.
Yes, and that is common. The symptoms are clumsiness, numbness and unsteadiness rather than pain. The absence of pain is one of the main reasons it is missed.
It may improve things, but the reliable benefit is stopping further loss. Some people recover considerably and many stabilise. That is the argument for operating earlier, while function is still good.
Myelopathy is compression of the spinal cord; radiculopathy is compression of a nerve root after it leaves the cord. Radiculopathy usually hurts and often settles by itself. Myelopathy often does not hurt and tends to progress.
Usually it develops slowly, over months or years. It can worsen abruptly after an injury, particularly where the canal is already narrow — which is why a fall in someone with known narrowing is worth taking seriously.
No. Bring any MRI or X-ray images, and note when you first noticed changes in your hands or walking and whether they have worsened. What someone close to you has observed is often more accurate than your own account.

Clumsy hands or unsteady walking without pain to explain it is worth examining properly — the signs that identify myelopathy are found by someone looking for them.
