Intellijoint Hip^®

Intellijoint HIP^® is a 3D miniature optical navigation device that provides surgeons with accurate, real-time intraoperative measurements to ensure proper selection and positioning of the new implant during hip replacement surgery. A miniature camera and tracker are used to accurately determine the cup position, leg length and hip offset.

Studies indicate component malposition causes instability¹ and dislocations² which are the most common causes of revision surgery for total hip arthroplasty.

With Intellijoint HIP's 3D mini-optical navigation technology, surgeons are able to obtain vital intraoperative measurements which assists with accurate size selection, positioning and alignment of implants³.

Intellijoint HIP can assist in the prevention of:

• Hip instability/dislocation
• Implant loosening
• Leg length inequality
• Premature implant wear
• Revision hip surgery
