What is a cervical disc replacement?
Replaces a damaged neck disc while preserving motion at the treated level. The damaged cervical disc is removed through an anterior approach, the nerve or spinal cord is decompressed, and an artificial disc is placed between the vertebrae.
Conditions it treats
Herniated Disc
Back and leg pain that travels. Most herniated discs improve without surgery.
Learn more →Cervical Myelopathy
Compression of the spinal cord in the neck. Early diagnosis protects function.
Learn more →Spinal Stenosis
When the spinal canal narrows, the goal is to give the nerves room.

Selected patients with cervical disc disease, arm pain, or nerve compression may be candidates when the facet joints and alignment support a motion-preserving option.
How the diagnosis and surgical level are confirmed
The central decision is whether motion preservation fits the diseased level. The review distinguishes arm-dominant nerve symptoms from isolated neck pain and examines strength, sensation, reflexes, gait, hand dexterity, alignment, disc height, and facet-joint condition. Severe facet disease, instability, unsuitable bone, or compression that cannot be addressed through the planned corridor may favor ACDF instead. During anterior decompression, freeing the nerve or cord safely takes priority over placing an artificial disc. Device sizing and position are chosen for the treated anatomy rather than to recreate an idealized amount of motion. Early follow-up includes swallowing or voice symptoms as well as the neurologic examination. Computer work requires sitting and screen-position tolerance; driving adds safe neck control; overhead and material-handling work adds arm endurance, lifting, and fall exposure. The device is not living disc tissue, does not reverse arthritis elsewhere, and cannot guarantee preserved motion.
How Dr. Merola performs cervical disc replacement
The damaged cervical disc is removed through an anterior approach, the nerve or spinal cord is decompressed, and an artificial disc is placed between the vertebrae.
Recovery timeline and returning to work
Walking begins early. Desk work may resume before heavier work, while lifting and overhead activity return on a staged plan after the incision, motion, and neurologic symptoms are reassessed.
Alternatives and related procedures
ACDF is the primary comparison. ACDF fuses the treated level; disc replacement is designed to preserve motion in selected anatomy.
Cervical Disc Replacement risks and outcomes
Risks include infection, nerve or spinal-cord injury, swallowing or voice symptoms, device movement or wear, heterotopic bone, and the possibility of later surgery.

Compare procedure →Frequently Asked Questions
How do I know whether I need a cervical disc replacement?
Selected patients with cervical disc disease, arm pain, or nerve compression may be candidates when the facet joints and alignment support a motion-preserving option. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during a cervical disc replacement?
The damaged cervical disc is removed through an anterior approach, the nerve or spinal cord is decompressed, and an artificial disc is placed between the vertebrae. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after a cervical disc replacement?
Walking begins early. Desk work may resume before heavier work, while lifting and overhead activity return on a staged plan after the incision, motion, and neurologic symptoms are reassessed. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to a cervical disc replacement?
ACDF is the primary comparison. ACDF fuses the treated level; disc replacement is designed to preserve motion in selected anatomy. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before a cervical disc replacement?
Risks include infection, nerve or spinal-cord injury, swallowing or voice symptoms, device movement or wear, heterotopic bone, and the possibility of later surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
