|Bone Graft Alternatives Lead To Shorter Recovery Times
Originally published Spring 2001
Patients requiring spinal fusions now face shorter recovery times thanks to new bone graft alternatives. Traditionally, bone from a patients own iliac crest was used to complete a spinal fusion. Today, we can now utilize banked bone as an alternative. This allows patients to avoid the pain and inconvenience of a donor incision, which often causes pain greater than that of the spinal incision itself.
In those cases where only banked bone is used for the graft material, pain is greatly reduced, and a significant reduction in hospital stay is possible, said Dr. Finger.
During spinal fusion, two or more vertebrae are welded together using grafted bone and internal devices such as metal rods. The result is a single, solid bone. This eliminates motion between vertebrae segments, which is often the cause of significant pain. Spinal fusion is used in the treatment of herniated disks, injuries to spinal vertebrae, a weak or unstable spine caused by infections or tumors, and abnormal spine curvatures such as scoliosis or kyphosis.
Supplements to grafting have been refined over the past 10 to 15 years, said Dr. Finger. We now use plates, screws, cages, and wires to help promote fusion. Newer titanium mesh cages are also available for those operations involving structural, or weight bearing bone.
Generally, over 90% of spinal fusions are successful. Patient factors such as diabetes, vascular disease, use of anti-inflammatory drugs (steroidal and non-steroidal), infection, and age, can all have a negative impact on the success of this procedure. According to Dr. Finger, tobacco may well be the largest negative factor. A patients chances for a successful fusion may be reduced up to 50% if he or she is a tobacco user.
