Abstract
A sensing insert device (100) is disclosed for measuring a parameter of the muscular-skeletal system. The sensing insert device (100) can be temporary or permanent. Used intra-operatively, the sensing insert device (100) comprises an insert dock (202) and a sensing module (200). The sensing module (200) is a self-contained encapsulated measurement device having at least one contacting surface that couples to the muscular-skeletal system. The sensing module (200) comprises one or more sensing assemblages, electronic circuitry (307), an antenna (2302), and communication circuitry (320). The sensing assemblages are between a top plate (1502) and a bottom plate (1504) in a sensing platform (121). The sensing assemblages comprise a load disc (2004) and a piezo-resistive sensor (2002) to measure the parameter. An elastic support structure or springs (1108) is coupled between the top plate (1502) and the bottom plate (1504) to prevent cantilevering of a surface.
