Abstract
A prosthetic component suitable for long-term implantation is provided. The prosthetic component measures a parameter of the muscular-skeletal system is disclosed. The prosthetic component comprises a first structure having at least one support surface, a second structure having at least one feature configured to couple to bone, and at least one sensor. The electronic circuitry and sensors are hermetically sealed within the prosthetic component. The sensor couples to the support surface of the first structure. The first and second structure are coupled together housing the at least one sensor. The first and second structures comprises steel, titanium, cobalt or an alloy thereof. At least one of the first or second structures is coupled to ground to shield the sensor from parasitic coupling. The at least one sensor can be a pressure sensor for measuring load and position of load.
