Abstract
Unicortical path detection for a measurement system for monitoring a depth of penetration of a working portion of an instrument in a bone of a patient. The unicortical detection may compare an average cortex thickness in a bicortical path to an actual measured depth of penetration. If the actual depth of penetration exceeds the average thickness, a unicortical path may be detected. Upon detection of a unicortical path, an alert may be provided and/or the instrument may be arrested upon subsequent breaching of the cortex.
