Understanding Spinal Disc Replacement Surgery

A Patient's Guide

What is Spinal Disc Replacement?

Spinal disc replacement is a surgical procedure that involves removing a damaged or worn disc in your spine and replacing it with an artificial disc made of metal or a combination of metal and medical-grade plastic. This surgery can be performed in either the neck (cervical) or lower back (lumbar) region. Unlike traditional spinal fusion surgery which permanently joins vertebrae together, disc replacement aims to maintain your spine's natural motion while reducing pain.

Who is a Good Candidate?

You may be a good candidate for disc replacement if you:

  • Have back pain primarily coming from only 1-2 discs
  • Have not found relief from conservative treatments after 6 months for lumbar or 3 months for cervical pain
  • Have no significant joint disease or nerve compression
  • Are not significantly overweight
  • Have not had previous spinal surgery
  • Don't have spinal deformities like scoliosis
  • Don't have osteoporosis (weak bones)
  • Are between ages 18-60

Who Should Not Have This Surgery?

This surgery may not be appropriate if you have:

  • Severe facet joint disease
  • Significant nerve compression or spinal stenosis
  • Osteoporosis
  • Previous spinal surgery at the affected level
  • Spinal deformity or instability
  • Severe obesity
  • Active infection

What to Expect During Surgery

The procedure typically takes 2-3 hours and requires general anesthesia. Your surgeon will:

  1. Make an incision (front approach for cervical, abdomen for lumbar)
  2. Carefully move aside blood vessels and organs to access the spine
  3. Remove the damaged disc
  4. Insert the artificial disc device
  5. Close the incision

Recovery Timeline

Hospital Stay: 1-3 days typical

  • Day 1: Walking encouraged
  • Week 1: Rest period with light walking; no lifting over 10-15 pounds
  • Week 2: May return to light desk work
  • Week 4-6: Begin physical therapy
  • Week 6: Those with physical jobs may return to work
  • 3 Months: Many patients reach maximum recovery

Expected Outcomes

Research shows disc replacement:

  • Maintains spinal motion better than fusion
  • Has success rates of 75-93% in reducing pain
  • Allows faster recovery than fusion
  • May reduce risk of adjacent segment disease
  • Does not completely eliminate pain but significantly improves it

Potential Risks

Like all surgeries, disc replacement has risks including:

  • Infection
  • Implant dislocation or failure
  • Blood clots
  • Nerve injury
  • Device loosening or wear
  • Heterotopic ossification (unwanted bone formation)
  • Need for revision surgery

Important Considerations

  • Insurance coverage varies; check with your provider
  • Long-term outcomes continue to be studied
  • Choose a surgeon experienced in disc replacement
  • Follow all pre and post-operative instructions carefully
  • Attend all follow-up appointments
  • Complete recommended physical therapy

Understanding Spinal Fusion Surgery with Expandable Cages

This comprehensive patient guide explains expandable cage devices used in modern spinal fusion surgery, a procedure that joins vertebrae together to relieve back pain. The document details how expandable cages offer advantages over traditional fixed cages, including smaller incisions, better spine alignment, and potentially faster recovery times. It covers the surgical procedure, expected outcomes, recovery timeline, and important warning signs to watch for after surgery. Created for patients considering or preparing for spinal fusion surgery, this guide combines information from both the American Academy of Orthopaedic Surgeons (AAOS) and recent medical research to provide an up-to-date overview of expandable cage technology in spine surgery. The guide includes essential details about surgical approaches, post-operative care, and success rates, making it a valuable resource for patient education about modern spinal fusion techniques.
