DEVICE: iFuse Bedrock Granite Implant System (00810055523788)

A small, threaded, implantable rod with a screw head and drive intended for internal spinal fixation by being screwed into the spine to hold a correction/stabilization device (e.g., rod, plate, tether) to bone; it is made of a material that is not chemically degraded or absorbed via natural body processes (e.g., surgical steel, titanium alloy, carbon fibre). It is available in various types (e.g., pedicle or transfacet, with a slotted, cross, star, or polygonal drive), and is typically used to provide immobilization and stabilization of spinal segments in the treatment of spinal instabilities or deformities. A screw head adaptor intended to stabilize a rod may be included with the screw.

An implantable device designed to be inserted across the sacroiliac joint to provide temporary stabilization and to encourage long-term joint fusion, typically to alleviate pain from the joint. It is made of metal [e.g., titanium (Ti)] with a porous plasma spray coating, and typically in the form of a cylinder or rod, possibly with a triangular cross-section. It is typically surgically implanted under fluoroscopic guidance and may include dedicated disposable implantation instruments.
