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 insert dock (202) is a passive component made for different prosthetic component manufacturers as well as for different size prosthetic components. The sensing module (200) fits in an opening or cavity of the insert dock (202). The intra-operative insert device is substantially equal in dimension to an implanted final insert. The sensing insert device (100) is also a permanent prosthetic component. The sensing module (200) residing within the sensing insert device and coupling to a bearing surface of the insert.
