What is it indicated for?

The Entasis 3D Dual-Lead Sacroiliac Implant System is intended for sacroiliac joint fusion for conditions including degenerative sacroiliitis and sacroiliac joint disruptions, to augment immobilization and stabilization of the sacroiliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion and acute, non-acute, and non-traumatic fractures involving the sacroiliac joint. This includes those whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months.
