The prosthetic device includes a shell with a cavity defined by an interior surface. The interior surface includes first and second portions that share an edge and that abut an edge of the interior surface. The first portion includes a partially spherical surface while the second portion is a partially cylindrical shape. A maximum radius of the second portion is larger than a radius of the first portion. A center defining the maximum radius of the second portion is offset from a center defining the radius of the first portion. The geometry of the interior surface allows the insert to be advanced into the shell in a single orientation. When advanced sufficiently into the shell, the insert is rotated to constrain the insert within the shell.5/8 10) 117B 14 3 0 20 13 3B-3B 3B-3B 12 17A 26 28 FIG. 3A 2620 S17A 17C 1 713 12 22 41 I s
