A system () for processing accelerometer data is disclosed. The system () includes an accelerometer (), a first processor (), a power supply (), and a second processor (). The accelerometer () measures a physiological acceleration parameter. The first processor () is operatively connected to the accelerometer (). The first processor () is configured to receive the acceleration parameter from the accelerometer () and configured to output machine readable acceleration data. The machine readable acceleration data includes time domain accelerometer data. The power supply () is electrically connected to the first processor (). The second processor () is configured to receive the machine readable acceleration data and transform the time domain accelerometer data into frequency domain accelerometer data. The frequency domain accelerometer data may be used to estimate patient healing status.

Processing sensed accelerometer data for determination of bone healing

An instrumented orthopaedic implant, such as an intramedullary (IM) nail, is disclosed. The implant has the capacity to provide an accurate measurement of the applied mechanical load across the implant. The implant includes sensors and associated electronic components located in recesses on the outer surface of the implant. The implant houses the sensing apparatus, the interface circuitry, the data transmitter, and the power receiver. The hermetically sealed housing is adapted for implantation in the body of a patient. The implant is used with a controller which communicates with it by telemetry, and there is an acting unit connected to the electronic components which is adapted to carry out a function based upon a condition detected by the sensors.

Telemetric orthopaedic implant

A telemetric system includes a telemetric implant, a reader unit adapted to read signals from the telemetric implant, and an antenna adapted for connection to the reader unit and to receive signals from the telemetric implant. The antenna has a first coil, a second coil, and a connector. The first coil is electrically connected to the second coil, and the connector allows for movement of the first and second coils relative to each other. The antenna may be used to send radio-frequency power to the telemetric implant and receives data from the telemetric implant.
