The Spinal Stiffness Gauge™ (SSG™)
The Spinal Stiffness Gauge is a hand-held powered and computer-driven, intraoperative surgical instrument. By applying a force to, and separating adjacent vertebrae at a constant rate of distraction, the SSG electronically measures the resistance of the adjacent vertebrae to the distraction. By providing an objective measurement of joint stiffness, joint stability, the SSG instrument assists the surgeon in determining the need to stabilize or fuse a spine joint.
Beyond determining when joint fixation is, or isn't necessary, the SSG can provide a hard copy measurement of the patient's joint stiffness, and a rationale for joint fusion with instrumentation--or joint reconstruction and restabilization without fusion.
