inserting reusable components of an inertial navigation system into an outer housing, the outer housing comprising an outer housing body comprising a transparent section and an outer housing cover, the reusable components of the inertial navigation system comprising at least one inertial sensor and a display configured to provide an indicator of an orientation of the reusable components of the inertial navigation system to a user during a surgical procedure;
positioning the reusable components of the inertial navigation system within the outer housing such that the transparent section of the outer housing body covers the display; and
closing the outer housing cover to provide a sterile barrier between the reusable components of the inertial navigation system and an outside environment.
