Spinal-FusionSpinal Fusion

What is spinal fusion?

Spinal fusion is the process of two or more vertebrae fusing together, immobilizing them to create a single continuous bone. It is used to treat broken vertebra, a spinal deformity, spinal weakness, spinal instability, or chronic low back pain.

 

Surgeons use a bone graft—extra bone tissue, either from the patient (autograft) or a donor (allograft)—in conjunction with the body’s natural bone growth (osteoblastic) processes so that spinal fusion can occur. This bone graft may be in a preformed shape or contained in a cage made of plastic, carbon fiber, or metal. Surgeons often use implanted plates, screws, or rods to hold the vertebrae and graft to promote healing. Once this bone graft heals, the vertebrae are permanently fused.

 

What type of surgery is needed for spinal fusion?

Surgeons sometimes perform this procedure using an “open” technique, creating an incision that provides a direct line of- vision to the vertebra, which simplifies the process of inserting the bone graft and implants. However, this may result in damage to surrounding healthy tissue, large scars, and postoperative pain.

 

Minimally-invasive surgery (MIS) uses smaller incisions and usually results in less postoperative pain and faster recovery.1 However, MIS requires many intraoperative X-rays (fluoroscopy) to compensate for the surgeon’s lack of direct line-of-vision.

 

Mazor Robotics Renaissance enables surgeons to overcome these limitations and perform precise spinal fusion.

 

 

Spinal-Fusion-Surgery-With-MazorRoboticsWhat are the advantages of spinal fusion with Mazor Robotics Renaissance?

Renaissance guides the surgeon’s tools and implants in both open and minimally-invasive surgery (MIS), to ensure greater accuracy when compared to freehand conventional spine surgery.1 This can result in fewer complications, less postoperative pain, and a faster recovery. In addition, with Mazor Robotics Renaissance® Guidance System, the surgeon may require less fluoroscopy during surgery.2
