Lumbar Artificial Disc Replacement (ADR)

Lumbar Artificial Disc Replacement (ADR) is a surgical procedure designed to treat certain lumbar spine conditions by replacing a damaged or degenerated intervertebral disc with an artificial disc. The goal is to maintain motion at the affected spinal segment while alleviating symptoms such as lower back pain. Here is an overview of lumbar artificial disc replacement for patients:

Indications:

• Degenerative Disc Disease: Wear and tear on lumbar discs leading to pain and reduced mobility.

• Herniated Disc: Protrusion of disc material causing compression of nerves.

• Radicular Leg Pain: Pain radiating down the leg due to nerve compression.

Preparation:

• Medical Evaluation: Patients undergo a thorough medical evaluation, including imaging studies (MRI, CT scans) to assess the extent of the lumbar spine issue.

• Discussion with Surgeon: The surgeon explains the procedure, discusses potential risks and benefits, and answers any questions the patient may have.

Procedure:

• Positioning: The patient is typically positioned on their stomach.

• Anesthesia: General anesthesia is administered to ensure the patient is asleep and pain-free during the procedure.

• Incision: An incision is made in the lower back to access the lumbar spine.

• Discectomy: The damaged or degenerated disc is removed.

• Artificial Disc Placement: An artificial disc implant is inserted to replace the removed disc. The implant is designed to mimic the function of a natural disc and allow controlled motion at the spinal segment.

• Closure: The incision is closed with sutures or staples.

Recovery:

• Hospital Stay: The length of the hospital stay is typically one to two days.

• Activity Restrictions: Patients are advised to avoid certain activities, such as heavy lifting or strenuous exercise, during the initial recovery period.

• Physical Therapy: Rehabilitation exercises and physical therapy are introduced gradually to help restore lower back strength and mobility.

Follow-up:

• Postoperative Visits: Patients have follow-up visits with the surgeon to monitor the healing process, address any concerns, and assess the effectiveness of the artificial disc.

• Imaging Studies: X-rays or other imaging studies may be conducted to evaluate the placement and function of the artificial disc.

Potential Risks and Considerations:

• As with any surgical procedure, there are risks, including infection, bleeding, and complications related to anesthesia.

• The success of the artificial disc replacement may vary among individuals.

• Artificial disc replacement preserves motion at the treated segment but may not be suitable for all patients.

It’s crucial for patients to have a detailed discussion with their healthcare team, including the surgeon, to understand the specifics of the surgery, potential risks, expected outcomes, and the postoperative care plan. The decision for surgery is individualized based on the patient’s specific condition and symptoms.

Is Lumbar Artificial Disc Replacement Right for You?

Not every patient with a damaged lumbar disc is a candidate for fusion and for those who qualify, artificial disc replacement can offer a meaningful advantage: keeping the spine moving naturally rather than locking a segment in place. Dr. Edionwe takes a thorough, individualized approach to evaluating candidacy for lumbar ADR, weighing factors like disc condition, spinal alignment, bone quality, and patient lifestyle before recommending surgery. For patients who do move forward, the goal is lasting pain relief with preserved mobility and a return to the activities that matter most. His practice serves patients throughout San Antonio and South Texas, including those traveling from the Rio Grande Valley and Laredo.
