Claim:
A modular humeral prosthesis kit for replacement of the humeral head of a humerus, comprising: (a) a stem to be fitted to a resected humerus; (b) an eccentric head adapted to approximate the size and shape of a humeral head, having an eccentric mating portion adapted to interface with an intermediate connecting member; (c) a plurality of intermediate connecting members of which one may be selected to connect the stem to the head, each intermediate connecting member comprising: a first connecting surface forming a cavity that is adapted to receive a structure that protrudes from the stem in order to mount the intermediate connecting member to the stem; and a second connecting surface adapted to be received in a cavity in the head in order to mount the head to the intermediate connecting member, the second connecting surface at least partially nested with the first connecting surface; the intermediate connecting members of the kit comprising: at least one intermediate connecting member in which the first and second connecting surfaces share an axis of rotation; at least one intermediate connecting member in which the first and second connecting surfaces are offset from each other; and at least one intermediate connecting member in which the first and second connecting surfaces are inclined at an angle relative to each other.
