Abstract: A prosthesis system of the present invention includes a monoblock stem extension including a proximal portion having a first neutral axis; and a distal portion defined by a longitudinal cylindrical shaft having a second neutral axis, wherein the second neutral axis is parallel and offset by a distance α from the first neutral axis; and an eccentric bushing arranged coaxial around the cylindrical shaft of the monoblock stem extension, the eccentric bushing including an external cylindrical shaft having a third neutral axis; and an internal cylinder having a fourth neutral axis that is substantially co-linear with the second neutral axis of the monoblock stem extension, wherein the third neutral axis is parallel and offset by a distance β from the fourth neutral axis.
