To take the guesswork out of spinal fusion surgery, New Zealand bioengineers have developed an implantable strain gauge that can measure the forces on the metallic devices used to prevent spinal column movement. If the spinal fusion is functional, there should be measurable strain, and this device provides quantitative evidence before the surgery is complete and the patient’s incision is closed. Then, over ensuing weeks and months, the gauge telemetrically demonstrates the continued integrity of the fusion without the need for an internal battery. The device should be ready for commercialization next year, and it may also be adapted to monitor joint prostheses in the hip and knee……someday soon.
