Development of a telemeterized shoulder prosthesis.
A telemeterized shoulder prosthesis was developed and tested, first in vitro and then in a cadaver implantation. The prototype prosthesis was instrumented with 3 strain gauges fixed within a hollow, tapered neck element whose output was used to determine the load vectors experimentally applied to the humeral head. Testing demonstrated accuracy of force measurement resolution to within 5% of actual applied forces. This design seems feasible for further investigations to develop a totally implantable telemeterized prosthesis.
