ABSTRACT:
A modular prosthesis allows two portions to be secured together with a selectable discrete relative angular orientation. A spline secured to one portion has projections which engage grooves in a cavity of the other portion to prevent angular motion between the portions. The spline and the cavity may be tapered to allow a pressure fit. Teeth secured to each portion may be used instead of a spline to secure the two portions in a selected discrete angular orientation. Alternatively, a pin may secure the portions together to prevent their relative angular movement. An additional securing means may also be used in combination with each of the above embodiments to further secure the two portions together.
