Abstract
A process for the measurement in vivo of the degree of bone consolidation, characterized in that it consists of implanting directly on the surface of the bone a transmitter with its power supply circuit, the oscillation frequency of the transmitter being capable of varying about a predetermined value during stresses applied to the bone to which the transmitter is secured. Signals emitted by the transmitter are received on a suitable external receiver positioned adjacent the transmitter. The receiver output signals are utilized for various purposes, such as checking, measurement and recording.
