Cervical myelopathy

What causes cervical stenosis

Narrowing of the cervical spinal canal is caused either by hypertrophy of the bone and ligaments, which reduces the space available to the spinal cord and nerves, or by a disc herniation compressing the cord and/or the exiting nerve roots.

Symptoms

Stenosis can produce sensory and motor symptoms — numbness and pain in the hand and fingers, typically beginning in the neck and travelling down the arms. If the spinal cord itself is significantly compromised, sensation and movement may be affected in the arms and legs simultaneously. This condition — a damaged, dysfunctional spinal cord in the neck — is called cervical myelopathy, and its presence changes the management approach fundamentally.

Why myelopathy is treated differently

When the spinal cord is affected, surgical decompression is always the first-line option. The reason is that any delay in relieving neural compression, once it is producing motor symptoms, can leave permanent deficits. In patients who are not operated on, or whose surgery is delayed, myelopathy and its symptoms may become irreversible, with severe and lasting motor, sensory, and neurological impairment.

It is worth noting the distinction between clinical myelopathy — the weakness and sensory disturbance a patient with cord injury actually experiences — and radiological myelopathy: a cord signal change identified on cervical MRI in a patient who has no symptoms at all.

In patients with symptomatic (clinical) myelopathy, surgery has a clear advantage over the alternatives, because it substantially reduces the likelihood of permanent motor and neurological deficit. The stakes are higher than in the lumbar spine: because of the role of the spinal cord, cervical myelopathy does not threaten the strength of one leg alone, but can cause weakness of all four limbs — a devastating outcome for the patient.

In asymptomatic patients with radiological findings alone, the picture is different. The published evidence does not show a clear advantage for surgery over close surveillance and conservative management in this group, and careful monitoring is therefore a reasonable alternative. If the patient goes on to develop clinical myelopathy — weakness or numbness in the arms and legs — surgery is clearly of benefit; if they never develop it, an operation would have been performed unnecessarily.

It is therefore entirely reasonable to monitor and to operate if and when symptoms appear — provided the operation is not delayed once they do.

Careful selection matters. Dr. Blionas proceeds to surgery only when conservative management has failed or is not appropriate. To avoid unnecessary or inappropriate treatment, every patient’s options are assessed individually through the AI-supported Personalized Evidence-Based Treatment Analysis, drawing on their own clinical characteristics and the most recent, validated evidence. Each patient is fully informed of what to expect from every option, and how their recovery is likely to proceed.

Surgical treatment of cervical myelopathy

Surgery is the definitive treatment for cervical myelopathy: it aims to decompress the spinal cord, preventing further neurological deterioration and permanent disability.

The choice of approach depends on where the compression lies, the patient’s anatomy, and their general condition. Options include discectomy, fusion, laminectomy, and corpectomy, performed either through an anterior approach (from the front of the neck) or a posterior approach (from the back).
