  • the user may couple the female adapter (110) to the prosthetic device (108). This coupling may be accomplished by inserting a portion of the male adapter (114) into the inner cavity (158) of the female adapter (110). Then, the user may insert alignment members (116) through the radial apertures (160) of the female adapter and into engagement with the male adapter (114). The engagement between the alignment members (116) and the male adapter (114) may rigidly couple the female adapter (110) to the male adapter (114). Further, the user may rigidly couple the male adapter (114) to the prosthetic device (108). In one embodiment, the male adapter (114) is coupled to the prosthetic device (108) using screws.

As a result, the rail member (308) may provide the front and back adjustment of the male adapter (300). Further, the rail member (308) may include different sizes. For example, three different rail member (308) sizes are illustrated: a large rail member (310C), a medium rail member (310B), and a small rail member (310A).
