This paper reports on the development of a metacarpal phalangeal prosthesis with an embedded NiTi pseudoelastic spring. The device was originally developed using a special steel spring. The use of a shape memory alloy was suggested by the observation of failures in the hinge structure of the prosthesis. In more detail it was frequently observed a permanent deformation of the stainles steel spring. In a large number of cases this was not due to the activation of the spring in the normal deformation range but by occasional overdeformation of the prosthesis.
