{6}------------------------------------------------

The technological principle for both the subject and predicate devices is to provide intra-operative measurements during orthopedic surgery. It is based on the use of infrared optical technology to provide real-time, intraoperative data on leg length, offset, and cup position.

The subject and selected predicate devices are based on similar technological elements. The system generates positional measurements between a camera and a tracker that can be mounted on different objects. The camera uses the application software and the tracking software to guide the surgeon through a workflow process for the surgery.
