Abstract
An artificial cotyloid socket having a domal outer shell (1) and a domal inner shell (2) subtending between them a cavity (3). Each of the outer and inner shells (1, 2) having a domal wall that merges into a rim (5, 6). The outer and inner shells are undetachably joined to each other at their rims (5, 6). The rim of the outer shell is reinforced and disposed relatively beneath a circle of merging (7). The circle of merging is defined by the intersection of the outer shell domal wall and the outer shell rim. A thickness of the wall continuously increases as one moves from a pole (4) of the outer shell toward the circle of merging (7).
