A method for producing predetermined internal stresses in a prosthetic device
for
implantation. The method includes first determining internal stresses which are
preferred in prosthetics to instill a particular strength and longevity to the
prosthetic. In particular, internal stresses may be used to increase the strength
of smaller prosthetic devices. Additionally, once the preferred internal stresses
are determined, the internal stresses can be cold worked into subsequent prosthetic
devices to instill the same characteristics. Once parts are manufactured, internal
stresses can be measured to validate manufacturing process and serve as verification
for quality control purposes. Producing prosthetic devices, including predetermined
internal stresses through work hardening the prosthetic devices, is described.
