Abstract
An implantable humeral shoulder prosthesis includes a stem and a head. The stem includes a distal stem portion having a longitudinal axis and a proximal body, and a first connector having an axis disposed at an acute angle relative to the longitudinal axis. The head includes an undersurface and a spherical articulating surface having a center. The undersurface includes a second connector having an axis that does not pass through the center. The articulating surface subtends a greater angle in a first plane including the axis of the second connector than in a second plane including the axis of the second connector. The first and second connectors are mutually engageable to interlock the head to the proximal body.
