The SOLACE Sacroiliac Fixation System is indicated for sacroiliac joint fusion for:
• Sacroiliac joint dysfunction including degenerative sacroiliitis and sacroiliac joint disruptions
• Augmenting immobilization and stabilization of the sacroiliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion.
The SOLACE Sacroiliac Fixation System is also indicated for fracture fixation of acute, non-acute, and nontraumatic fractures involving the sacroiliac joint.
The SOLACE Sacroiliac Fixation System Navigation Instruments are intended to be used with the SOLACE Sacroiliac Fixation System during surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. These instruments are designed for use with the Medtronic StealthStation System S8, in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as the pelvis or vertebra, can be identified relative to a CT or MRI based model, fluoroscopy images, or digitized landmarks of the anatomy.
Indications for use as stated in the FDA summary.
