Lumbar Artificial Disc Replacement

Lumbar artificial disc replacement (ADR) is a surgical procedure used to treat degenerative disc disease in the lumbar region of the spine. In this procedure, a damaged or degenerated disc is removed and replaced with an artificial disc. In this article, we will discuss the procedure of lumbar artificial disc replacement, its benefits, risks, and recovery time, and provide some reference links for further reading.

Procedure:
Lumbar artificial disc replacement surgery is typically performed under general anesthesia. During the procedure, a small incision is made in the abdomen or back, and the affected disc is removed. The artificial disc is then inserted in its place.

The artificial disc is designed to mimic the natural structure and function of a healthy disc. It is made of two metal plates with a polyethylene spacer in between. The plates are attached to the vertebrae above and below the replaced disc, and the spacer allows for normal movement of the spine.

Benefits:
Lumbar artificial disc replacement has several benefits over traditional spinal fusion surgery. Because the artificial disc allows for normal movement of the spine, patients may experience greater flexibility and a reduced risk of adjacent segment disease. Additionally, the recovery time for lumbar artificial disc replacement is typically shorter than that of spinal fusion surgery.

Risks:
As with any surgical procedure, there are risks associated with lumbar artificial disc replacement. These can include infection, bleeding, nerve damage, and device failure. In rare cases, the artificial disc may need to be removed and replaced with a fusion.

Recovery:
Following lumbar artificial disc replacement surgery, patients may need to stay in the hospital for a few days to be monitored. During this time, pain medication may be administered to manage pain. Patients are typically advised to limit activity and avoid heavy lifting for several weeks following the procedure. Physical therapy may be recommended to help patients regain strength and mobility.
