Devices, systems and methods for using and monitoring orthopedic hardware

A method for detecting and/or recording an event in a subject with an implanted medical device comprising one or more sensors configured to obtain evaluation data characterizing motion or movement of the implanted medical device, where the one or more sensors comprises an accelerometer, where the implanted medical device is an intramedullary rod inserted in a fractured bone of the subject,

• the method comprising the steps a) instructing by the subject an external signaling device to send an interrogation signal to the implanted medical device, the instructing being performed by the subject at a desired point in time when the subject experiences a particular event;
• b) simultaneously obtaining the evaluation data at the desired point in time from the one or more sensors of the implanted medical device in response to the interrogation signal;
• and c) recording the evaluation data in a memory;
• the method additionally comprising the steps d) transmitting a wireless electrical signal from a location outside the subject to a location inside the subject;
• e) receiving the wireless electrical signal at the one or more sensors;
• f) powering the one or more sensors using the received wireless electrical signal;
• and g) outputting the evaluation data to a receiving unit located outside of the subject.
