An apparatus (10) that utilizes microelectromechanical systems (MEMS) technology to provide an in vivo assessment of loads on adjacent bones (24 and 26) comprises a body (34) for insertion between the adjacent bones. At least one sensor (42) is associated with the body (34). The sensor (42) generates an output signal in response to and indicative of a load being applied to the body (34) through the adjacent bones (24 and 26). A telemetric device (40) is operatively coupled with the sensor (42). The telemetric device (40) is operable to receive the output signal from the sensor (42) and to transmit an EMF signal dependent upon the output signal. According to various aspects of the invention, the sensor comprises a pressure sensor (42), a load cell (320), and/or at least one strain gauge (142).

L'invention concerne un appareil (10) qui utilise la technologie des syst­mes m~caniques micro~lectriques pour effectuer une ~valuation in vivo des charges sur des os adjacents (24 et 26), l'appareil comprenant un corps (34) pour insertion entre lesdits os. Au moins un capteur (42) est associ~ au corps (34). Le capteur (42) g~n­re un signal de sortie en r~ponse ~ une charge et indiquant l'application de celle-ci audit corps (34) ~ travers les os adjacents (24 et 26). Un dispositif t~l~m~trique (40), raccord~ de mani­re fonctionnelle au capteur (42), permet de recevoir le signal de sortie ~manant du capteur (42) et d'~mettre un signal de champ ~lectromagn~tique en fonction du signal de sortie. Selon divers modes de r~alisation, le capteur comprend un capteur de pression (42), une cellule de mesure (320) et/ou au moins un tensiom­tre (142).
