Abstract
Abstract Humeral prosthesis having a rod for anchoring into a humeral canal of a humerus. The prosthesis has a hemispherical cup adapted to engage a shoulder socket and a connection which connects the rod to the hemispherical cup. The connection includes a spherical portion and the spherical portion includes a spherical engaging surface having at least one recess. At least one reference mark is disposed on at least one of the rod, the hemispherical cup, and the connection. The at least one reference mark corresponds to the at least one recess. The prosthesis also has a binding mechanism for engaging the at least one recess. The hemispherical cup is pivotal about the spherical portion and fixable in a finite number of combined angular positions which correspond to a number of recesses.
