Spinal fusion is among the most commonly performed orthopedic surgeries in the United States, with more than 400,000 patients undergoing the procedure each year. Although most cases are successful, as many as 45 percent of patients experience complications after the operation, often resulting from the bone s inability to tolerate the hardware surgeons use to support the skeleton.
The most widely used technology to evaluate patients bones before spine fusion surgery is called dual x-ray absorptiometry, or DXA. DXA imaging gives physicians a rough sense of the strength of a person s bone, but it is not foolproof. In some cases, surgeons find that patients whose DXA scans appear normal have bones that are so weak that the appliances they use during spinal fusio
