Patent ID: 7338528

Claim:
A kit of prosthetic components comprising: a first monolithic stem having a first longitudinal axis and a first proximal end defining a first mounting portion, said first mounting portion defining a first coupling mechanism having a first taper having a first coupling mechanism axis, said coupling mechanism axis intersecting the first longitudinal axis at a first fixed distance along the first longitudinal axis from said first proximal end wherein the first proximal end and mounting portion are a monolithic structure; and a second monolithic stem having a second longitudinal axis and a second proximal end defining a second mounting portion, said second mounting portion defining a second coupling mechanism with a second taper having a second coupling mechanism axis, said second coupling mechanism axis intersecting the second longitudinal axis at a second fixed distance along the second longitudinal axis from said second proximal end wherein the second proximal end and mounting portion are a monolithic structure and said first distance is less than said second distance, and a first head selectively mateable with either the first or second coupling mechanisms, the head having a medial edge displaced from the first longitudinal axis of the first monolithic stem or the second longitudinal axis of the second monolithic stem by less than about 5 millimeters.
