Patent ID: 10398477

Abstract:
A Static Compression Device (SC device) for active, measurable compression of a spinal fusion graft is disclosed. The device attaches to adjacent vertebral bodies or other bone pieces works with a compression tool to apply compressive force to adjacent vertebral bodies or pieces of bone to assist fusion. Once compressed, the SC device locks to maintain the compression applied at surgery, while preventing further compression after surgery. In one embodiment, the compression device applies a desired, quantified, amount of force to allow the surgeon more control over the force applied to a cervical, thoracic or lumbar implant than previously available. The SC device may be used to compresses multiple adjacent vertebrae across adjacent bone graft(s) to facilitate fusion of these vertebrae to treat pain from damaged disks between vertebrae that impinge on the spinal cord and nerve roots. SC device may also apply compression across fractures to facilitate union.
