In this surgical procedure, a titanium alloy device is implanted to relieve back pain or numbness in the legs or buttocks caused by spinal stenosis. This procedure is a non-fusion, minimally invasive alternative to laminectomy with or without spinal fusion.
Anesthesia is administered and the patient is positioned. A small incision is made in the lower back.
An opening is created through the ligaments at the rear of the spine. The surgeon can now access the spinous processes, the bony protrusions on the back of the spine, of the problem vertebrae.
Some of the bony overgrowth of the spinous process may need to be removed for the implant to fit properly. A small portion of one or more lamina may also need to be resurfaced.
Using fluoroscopic guidance, the Coflex implant is inserted through the incision and placed between the spinous processes.
In many cases, the patient will be able to return home the same day or after an overnight stay. The surgeon will determine the length of the hospital stay and will guide the post-operative recovery.
