Lumbar Disc Replacement in Los Angeles

Lumbar disc replacement, also called lumbar artificial disc replacement (ADR), is a motion-preserving surgery that removes a damaged spinal disc and replaces it with an artificial disc. The goal is to relieve disc-related low back pain while maintaining movement at the treated level.

Candidates are typically patients with symptomatic lumbar degenerative disc disease whose pain has not improved with appropriate nonoperative treatment. Candidacy depends on factors such as the source of pain, spinal stability, facet joint health, bone quality, alignment, and the location and severity of disc degeneration.

Lumbar disc replacement is designed to preserve motion at the treated spinal level. Lumbar fusion permanently joins adjacent vertebrae and eliminates motion at that segment. Disc replacement may be an alternative to fusion in appropriately selected patients, while fusion may be more appropriate when significant instability, deformity, poor bone quality, or advanced facet arthritis is present.

Neither procedure is best for every patient. Lumbar disc replacement may offer advantages for appropriately selected patients, including preservation of spinal motion and avoidance of fusion at the treated level. The best procedure depends on the patient's anatomy, diagnosis, symptoms, spinal stability, facet joints, and treatment goals.

Yes. Two-level lumbar disc replacement may be performed in appropriately selected patients with symptomatic degeneration involving two adjacent lumbar discs. Whether a patient qualifies depends on the specific levels involved, implant indications, spinal anatomy, bone quality, facet joint condition, and overall spinal stability.

Lumbar disc replacement is primarily used to treat painful lumbar degenerative disc disease and discogenic low back pain in carefully selected patients. It is not intended to treat every cause of back pain, which is why identifying the source of the patient's symptoms is an important part of the evaluation.

Lumbar disc replacement is generally performed through an anterior approach, meaning the surgeon reaches the lumbar spine through the abdomen rather than through the muscles of the lower back. The damaged disc is removed, the disc space is restored, and an artificial disc is positioned between the vertebrae to maintain motion.

Patients are typically encouraged to begin walking soon after surgery and gradually increase their activity during recovery. Many patients make substantial progress over the first several weeks, with return to more demanding activities occurring gradually over the following months. Recovery varies depending on the individual, number of levels treated, overall health, and activity demands.

Modern artificial lumbar discs are designed for long-term implantation. Clinical studies have demonstrated durable outcomes at long-term follow-up, although no artificial implant can be guaranteed to last indefinitely. Implant longevity depends on several factors, including positioning, anatomy, activity level, bone quality, and the condition of the surrounding spine.

As with any spine surgery, lumbar disc replacement has potential risks, including infection, bleeding, nerve or vascular injury, implant migration or wear, persistent symptoms, heterotopic bone formation, and the possibility of additional surgery. An individualized surgical evaluation is necessary to determine whether the potential benefits outweigh the risks.

Yes. Returning patients to an active lifestyle is often an important goal of lumbar disc replacement. Walking usually begins early, while strengthening, cardiovascular exercise, sports, and heavier activities are introduced progressively based on healing and the surgeon's recommendations.

Many appropriately selected patients return to recreational exercise and sports after recovery from lumbar disc replacement. The timing and type of activity depend on healing, conditioning, the number of levels treated, and the physical demands of the sport.

Studies of appropriately selected patients have demonstrated significant improvements in pain and function following lumbar artificial disc replacement, along with preservation of motion at the treated level. Individual outcomes vary depending on diagnosis, patient selection, surgical technique, and other medical and spinal factors.

Lumbar disc replacement may not be appropriate for patients with conditions such as significant spinal instability, advanced facet joint arthritis, severe osteoporosis, certain spinal deformities, infection, or other anatomical conditions that make an artificial disc unsuitable. Each patient requires an individualized evaluation.

Insurance coverage for lumbar disc replacement varies by insurance carrier, diagnosis, treatment level, implant, and the patient's individual policy. Prior authorization is often required. The surgeon's office can review coverage requirements and help determine whether the procedure may be covered.

Patients considering lumbar disc replacement in Los Angeles should seek evaluation from a spine surgeon experienced in both motion-preserving surgery and spinal fusion. A comprehensive evaluation can determine whether disc replacement, fusion, continued nonoperative treatment, or another treatment option is most appropriate.
