Abstract

A system for providing information related to an orthopaedic surgical procedure to a surgeon includes a user-worn computer coupled with a heads-up display. The user-worn computer and the heads-up display cooperate to display orthopaedic surgical information to the surgeon. The user-worn computer receives data from a first processing circuit and a second processing circuit. The first processing circuit determines navigational data based on data signals received from navigation sensors. The second processing circuit determines patient condition data based on data signals received from patient condition sensors. Additionally, the system may include one or more peripheral ports for receiving a removable memory device.
