Cervical myelopathy — compression of the spinal cord in the neck — causes progressive weakness, clumsy hands, and gait instability without neck pain. Dr. Anand Karnam explains this under-diagnosed condition and why surgery timing matters.
Key Points
- Cervical myelopathy (spinal cord compression in the neck) causes weakness, clumsiness, balance problems, and bladder urgency.
- The classic sign: difficulty with fine finger tasks (buttoning, writing) and unsteady gait — in an otherwise alert patient.
- MRI of the cervical spine is the essential investigation — shows cord signal change and degree of compression.
- Surgical decompression is indicated for significant myelopathy — delay leads to irreversible cord damage.
- Without surgery, 70% of cervical myelopathy patients worsen over 5 years.

"Myelopathy is one of the diagnoses I fear missing. A patient who has been treated for months with physiotherapy for 'back pain' turns out to have cervical cord compression. The MRI takes 30 minutes — it should have been done months earlier."
Cervical myelopathy — compression of the spinal cord itself within the cervical spine (neck) — is one of the most common causes of spinal cord dysfunction in adults over 50, yet it is frequently under-diagnosed or misattributed to "normal ageing." Unlike radiculopathy (nerve root compression causing arm pain), myelopathy compresses the spinal cord, producing symptoms below the level of compression — in the hands, trunk, and legs — often without neck pain at all.
Causes
The spinal canal becomes narrowed (stenotic) due to: cervical spondylosis — degenerative disc disease with osteophyte formation; disc herniation; hypertrophy of the ligamentum flavum (the ligament behind the cord); congenitally narrow spinal canal (a risk factor for myelopathy developing at a younger age with less degeneration); OPLL (ossification of the posterior longitudinal ligament — more common in East and South Asian populations).
Clinical Features — The Myelopathic Pattern
Hands: clumsy, difficulty with fine motor tasks (buttoning shirts, writing, using chopsticks — the "myelopathic hand"); intrinsic muscle wasting; the "finger escape sign" (the little finger spontaneously drifts outward when the patient tries to hold all fingers extended and together). Legs: stiff, spastic gait; difficulty climbing stairs; sense of heaviness; may have "electric shock" sensation shooting down the spine and into the legs with neck flexion (Lhermitte's sign). Bladder: urgency and frequency. Reflexes: brisk throughout with Babinski sign.
Treatment — Why Timing Matters
Myelopathy is generally progressive — though the rate is variable. Neurological deficits that develop from myelopathy are partially reversible if decompressive surgery is performed before cord damage becomes severe and irreversible. The surgical window is critical: patients with moderate disability who are operated on in time typically stabilise or improve; those who wait until severe disability often do not recover function even after cord decompression.
