Disc Replacement

What is Disc Replacement?

Disc replacement is a type of spine surgery that involves removing a worn or damaged disc and replacing it with an artificial disc. These artificial devices are constructed from metal, sometimes combined with plastic materials, and are designed to mimic the natural movement of a healthy disc.

Advantages Over Spinal Fusion

Unlike spinal fusion, which permanently joins two vertebrae together, disc replacement preserves the natural motion of your spine. Key advantages include:

• Preserved mobility: Maintains normal spinal movement at the treated level
• Faster recovery: No waiting for bone fusion to heal
• Reduced stress: Less strain on adjacent spinal segments
• Natural feel: More closely mimics normal spine function

Who is a Candidate?

Disc replacement may be an option if you have:

• Persistent back pain from a damaged or worn disc
• Pain that hasn't responded to conservative treatments
• Single or two-level disc disease
• No significant facet joint disease or spinal instability
• Good overall health

Dr. Lee takes a conservative approach, always exploring nonsurgical options first before recommending surgery.

The Procedure

• Preparation: Thorough medical history review and physical examination to confirm candidacy
• Anesthesia: General anesthesia during the procedure
• Approach: An abdominal incision allows access to the spine without displacing nerves
• Duration: Typically 2-3 hours
• Hospital stay: Usually 1-3 days post-surgery

Recovery

Recovery from disc replacement is often faster than spinal fusion because there's no need to wait for bone to fuse. Most patients can:

• Walk within hours of surgery
• Return to light activities within a few weeks
• Resume normal activities within 4-6 weeks

Physical therapy helps restore strength and flexibility during the recovery process.
