## Indications for use
The Acumen TM Surgical Navigation System is intended to assist the surgeon in providing orientation and reference information to anatomical structures during open or percutaneous orthopedic procedures. The Acumen TM System is indicated for use in surgical knee and hip procedures, in which the use of stereotaxic surgery may be appropriate, and where reference to rigid anatomical bony structures, can be identified relative to fluoroscopy (hip procedures) or an imageless model of the anatomy (knee procedures). These procedures include, but are not limited to, knee and hip arthroplasty procedures.
