There are many causes of neck pain, especially as the spine begins to age. Like a few gray hairs and a wrinkle or two, the spine has its own characteristic age-related changes. With age, the cervical curvature shifts, osteophytes (abnormal bony spikes) can appear on the vertebrae, intervertebral discs can herniate, and the ligamentum flavum thickens and may even calcify. Symptoms usually result from a combination of all of these. The end result of static and dynamic mechanical factors produces a variable degree of cervical canal narrowing, which causes myelopathy (involvement of the spinal cord) and/or radiculopathy (involvement of the nerve roots).

Send my studiesIt is the most common degenerative disease of the spine in people aged 55 and older. An estimated 60 per 100,000 individuals in the U.S. have this condition, and it is a leading cause of disability in older adults. The main clinical challenge is timely diagnosis and timely treatment — because untreated spinal cord injury can become irreversible.
There is no single clinical finding that defines this disease. Onset is insidious — not sudden — and it presents as a constellation of symptoms. Pain is persistent. Chronologically, it often unfolds like this:
The lower limbs are affected first: gait disturbance, stiffness, difficulty moving the legs. Patients complain of trouble walking, bumping into things, and feeling unable to balance properly.
The condition then manifests in the arms and hands: gradual loss of strength and dexterity, numbness, tingling. Eventually, hand muscle atrophy appears. Patients drop objects they used to handle easily.
Often overlooked: changes in bowel and urinary function. In very advanced cases there can be incontinence.
Sudden severe pain after a fall or whiplash, rapid loss of strength, loss of sphincter control, or numbness in the perineal area require immediate evaluation. Don't wait.
Once the clinical diagnosis is established, a non-contrast cervical MRI is required to confirm the findings of the physical examination. This study also establishes the severity of the disease and informs surgical planning. AP, lateral and dynamic cervical X-rays are obtained to determine whether the cervical spine is balanced or not. When symptoms are subtle, functional studies can support early decision-making.
- Preserve or improve neurological function.
- Correct coronal and sagittal deformity.
- Maintain spinal stability.
Timely surgery is the cornerstone of treatment for this disease. As with any condition that may require surgery, many factors influence the when, where and how for each patient: severity of signs and symptoms, age, lifestyle (smoking), concomitant diseases (diabetes, obesity, pulmonary disease) and the surgeon's personal experience.
What is known: more than half of patients with imaging findings and symptoms — even mild ones — will deteriorate progressively and require surgery at some point. This is why waiting until you 'really can't take it anymore' is not a wise strategy: by then, some of the neurological damage may already be permanent.
It is a safe technique for treating cervical radiculopathy, whether central (midline) or foraminal (through the openings where nerve roots exit). A small incision is made at the back of the neck, and only the part of the vertebra and ligament compressing the spinal cord is removed. The scar is barely visible. When this approach is appropriate, the advantages are substantial:
- Crucial anatomical structures for neck stability and range of motion are preserved — both at rest and in movement.
- Lower risk of nerve root injury, particularly C5 palsy.
- Reduced risk of re-stenosis from scarring.
- Less blood loss, shorter operative time, lower cost and faster recovery.
- Less postoperative pain.
- No implants left behind — no screws, cages or fixation hardware.
During minimally invasive surgery, small incisions are made and every tissue manipulated is magnified up to 40 times with a microscope. Current evidence shows MIS produces clinical results comparable to open surgery, with the additional advantages of less blood loss, less postoperative pain and shorter hospital stay.
For multilevel CSM and ossification of the posterior longitudinal ligament (OPLL), two major posterior options compete: laminoplasty (LP), which preserves motion, and laminectomy with fusion (LF), which trades motion for stability.
A technical refinement worth knowing: a 2024 systematic review and meta-analysis found that laminoplasty combined with C3 laminectomy is an effective approach for multilevel degenerative cervical myelopathy, helping maintain cervical sagittal balance. The authors caution that the underlying evidence quality is still low and more high-quality studies are needed before this becomes a universal recommendation.
For anterior approaches, the historic standard is anterior cervical discectomy and fusion (ACDF), which sacrifices motion at the operated level. Cervical disc arthroplasty (CDA) is the modern motion-preserving alternative: instead of fusing the vertebrae, an artificial disc is implanted that allows the segment to keep moving.
In plain terms: when CDA is anatomically suitable, it preserves motion and tends to cause less neck pain in the first year compared with ACDF. It is not the right answer for every patient — anatomy, alignment, facet arthropathy and the number of levels involved all matter — but it deserves explicit discussion in your consultation rather than being skipped over.
In 92–97% of well-indicated cases, radicular (arm) pain resolves completely after surgery. The duration and severity of preoperative symptoms are decisive factors in how much improvement you can expect. Even in advanced cases, surgery can stop further progression of the problem. In summary: in every case there is benefit, to a greater or lesser degree.
After 24–36 hours in the hospital, recovery can be continued safely at home.
Spine surgery understandably generates concern about what can go wrong. We grew up with stories of three months in bed and patients who could no longer walk afterward. That picture is outdated. Today, most complications associated with cervical spine surgery are linked to pre-existing conditions — very advanced age, hypertension, diabetes, obesity — which can trigger pneumonia, wound infection, pulmonary embolism, prolonged intubation, myocardial infarction or deep venous thrombosis. A multidisciplinary team is essential to minimize this risk.
Should I have surgery or not?
Only a specialist can determine the best therapeutic path for your individual clinical condition. The decision should be made jointly, with full understanding of the risks, the benefits and the goals — whether you decide to have surgery or not.
What must be absolutely clear: this is a treatable disease, the surgery is a safe procedure, and you don't need to 'tough it out' until you really can't take it anymore. Untreated spinal cord injury can become irreversible — and when possible, the right answer is a procedure that preserves cervical motion.
