Abstract

A prosthetic device includes a socket, fasteners, and a pylon. The socket defines a cavity configured to receive a residual limb of a user. The socket includes a base defining multiple blind-holes. Each of the fasteners are configured to be received within a corresponding one of the blind-holes. The fasteners each include internal threads. The pylon includes through-holes that are aligned with a corresponding one of the blind-holes. The pylon is configured to be directly coupled with the base of the socket through externally threaded fasteners that extend through the through-holes and threadingly couple with the internal threads of the plurality of fasteners.
