Abstract

A system (30) is provided which non-invasively evaluates the condition of the interface between an implant (32) and bone using acoustic energy. Variations in the acoustic energy received from the implant (32) are analyzed to provide an indication of proper healing or loosening. Similar principles are applied to assess the extent of healing associated with bone fractures. In a related embodiment, the system utilizes built-in sensors (162) to detect the load imparted on an implant to evaluate non- invasively the amount of healing/loosening which occurs in relation to an implant. According to another particular embodiment, a signal source (38) is utilized to transmit a signal through the region of interest such as a fracture site (150) in order that healing may be evaluated.
