Top Rated U.S. Spine Surgeon

If you’re experiencing pain in your lower back, there is a possibility that it could be caused by a pinched nerve in the lower lumbar spine. This happens as the result of a diseased or damaged vertebral disc, which creates a smaller space for the affected nerve root to pass between the upper and lower vertebrae. If this is the case, disc replacement surgery may be the answer. The procedure consists of an orthopedic surgeon removing the damaged disc and replacing it with an artificial prosthesis.

During disc replacement spine surgery, a small incision is made in the abdomen. Through this incision, the damaged disc is removed and the upper and lower vertebral bones are cleaned of all cartilage and debris left behind. The two vertebrae are spread apart, taking pressure off of the pinched nerve and preparing the bone surfaces to accept the implant. A metal endplate is tapped into place on the two exposed surfaces. A flexible, round polyethylene cushion is inserted between the two endplates. When the spine is allowed to return to its normal position, the cushion is held between the two endplates, which are more firmly seated into the bone.

After a careful x-ray evaluation of the artificial disc’s successful placement, your orthopedic surgeon will determine if any further measures need to be taken. The Central Texas Spine Institute of Austin, Texas offers the skills and experience of Dr. Randall F. Dryer, one of the area’s most prominent spine experts.
