Disk Replacement Surgery (Artificial Disk Replacement)

Houston Methodist spine surgeons perform disk replacement surgery, also called artificial disk replacement or disk arthroplasty, to treat specific spinal conditions involving disk damage or degeneration that cause pain due to nerve compression or loss of normal disk function when non-surgical treatments have not provided relief. This surgical approach replaces the damaged disk with an artificial one designed to preserve motion at the treated level.

At Houston Methodist, disk replacement is not a first‑line treatment. Surgery is considered only when non-surgical care has failed and clinical findings clearly support disk replacement as an appropriate option. Our orthopedic spine surgeons and neurosurgeons work together to carefully evaluate whether disk replacement — or another surgical or non-surgical approach — best fits your condition, anatomy and long‑term goals.

What Is Disk Replacement Surgery?

Disk replacement surgery removes a damaged spinal disk and replaces it with an artificial device designed to preserve motion and maintain spacing between vertebrae. This procedure can serve as an alternative to spinal fusion  for select patients in the cervical (neck) or lumbar (lower back) spine.

How Does Disk Replacement Surgery Work?

Disk replacement surgery is typically performed under general anesthesia. During the procedure, your surgeon removes the damaged or degenerated disk through an anterior approach — either in the neck or abdomen — depending on the location being treated.

Once the disk is removed, an artificial disk device is placed in the empty space to restore height and allow continued motion. The implant is designed to mimic the function of a natural disk while maintaining flexibility and stability. When appropriate, minimally invasive techniques and advanced imaging may be used to support precision and surgical accuracy.

Disk Replacement vs. Spinal Fusion

Disk replacement and spinal fusion are both surgical options used to treat spinal conditions, but they differ in approach and outcomes. Disk replacement preserves motion at the treated level, while spinal fusion permanently joins vertebrae and eliminates motion.

Disk replacement may be considered for younger patients with single‑level disease and no spinal instability. Spinal fusion may be recommended for patients with multi‑level disease, spinal deformity, instability or prior surgery. Houston Methodist spine specialists evaluate each case carefully to determine the safest and most durable option.

What Conditions Does Disk Replacement Surgery Treat?

Disk replacement may be used to treat spinal conditions involving disk damage or degeneration that cause pain and reduced mobility when non-surgical treatment options have not provided adequate relief. In many cases, patients continue with non-surgical care until symptoms, function or stability change enough to warrant surgery.

Degenerative Disk Disease

Degenerative disk disease is a common, age‑related condition in which spinal disks gradually lose their shock‑absorbing ability. Symptoms can include back or neck pain, radiating pain, numbness and reduced flexibility. Physical therapy and pain management are typically first‑line treatments before disk replacement is considered.

Herniated Disk

A herniated disk occurs when disk material compresses nearby nerve roots, causing pain, numbness or weakness. In select cases without instability, disk replacement may be recommended to remove the damaged disk and preserve motion.

Radiculopathy

Radiculopathy refers to nerve root compression that causes radiating pain, tingling or weakness in the arms or legs. Disk replacement can sometimes relieve nerve compression while maintaining motion at the affected level.

Who Qualifies for Disk Replacement Surgery?

Disk replacement surgery is typically considered only after a confirmed neck or back condition diagnosis and conservative, non-surgical treatments — such as physical therapy, pain management and medication — have not adequately relieved symptoms.

Candidacy depends on several factors, including spinal stability, alignment, severity of symptoms, overall health and bone density. Ideal candidates generally have single-level disease, no significant spinal instability and no prior surgery at the affected level.

Your care team will review imaging tests such as MRI or CT scans, along with your treatment history and symptoms, to determine whether disk replacement is the safest and most durable option — or whether a less invasive or alternative surgical approach may be more appropriate.

Preparing for Disk Replacement Surgery

Preparation begins before the procedure. Your doctor may recommend steps such as:

• Doing pre‑surgical strengthening or conditioning exercises
• Avoiding smoking, vaping or other tobacco use
• Adjusting medications, including blood thinners
• Arranging a home support system, including help with transportation, meals and daily activities
• Planning for post‑surgical support
• Eating a healthy, protein‑rich diet
• Showering with antimicrobial soap before surgery to prevent infection
• Avoiding food and drink after midnight before the procedure

Recovering From Disk Replacement Surgery

Like other spine procedures, disk replacement surgery is a major surgery, and recovery varies by individual and procedure type. Most patients stay in the hospital for one to two days.

Many patients can return to light activity within a few weeks, with a gradual return to work based on job demands. Because motion is preserved, recovery may be faster than spinal fusion in some cases, though full recovery can take several months.

Walking regularly supports circulation and healing. Avoid bending, lifting and twisting during early recovery. Physical therapy often plays an important role in restoring strength and mobility, and your doctor will guide you through activity restrictions and pain management.
