Abstract
A implantable bone distraction device for distracting osteotomically separated bone sections includes a first block, a second block, and an actuator including elements for adjusting the space between the two blocks, a vibration sensor arranged in an area located between the first block and the second block and oriented in order to measure a vibration response of a medium of the implantable bone distraction device. A medical monitoring device includes a receiver for receiving data from an implantable bone distraction device, corresponding to a mechanical vibration response of a medium; a calculator for computing from the received data a distraction indicator by: (i) determining a vibration pattern of the medium from the measured vibration response; (ii) analyzing the evolution of a value of the vibration pattern from the measured vibration response during a first period; and (iii) generating a distraction indicator when the value exceeds a predefined threshold.
