Abstract: A method for custom fitting prosthetic devices, comprising the steps of: (a) providing a unitary prosthetic coupling device adapted to couple a prosthetic pylon to a second prosthetic limb component, the coupling device having a cylindrical sheath extending from a cavity adapted to receive at least a portion of the second prosthetic limb component therein, the cylindrical sheath adapted to interface with a prosthetic pylon, the cylindrical sheath accommodating various depths of pylon insertion to provide height adjustability with the second prosthetic limb component, the coupling device further being designed for day-to-day use; and (b) mounting the second prosthetic limb component to the prosthetic coupling device and mounting the prosthetic pylon to an interior surface of the cylindrical sheath so as to provide a secure coupling between the prosthetic pylon and the second prosthetic limb component enabling day-to-day use.

Abstract: A prosthetic coupling comprising an annular coupling adapter having a coupling end and an opposed pylon mounting end, the coupling end including a central bore adapted to receive, and be coupled to a prosthetic limb pyramid component, where the pylon mounting end includes a diametrically restrictable tube with at least two circumferential discontinuities and an axial depth with a predetermined extension greater than a minimum depth required to adequately secure a prosthetic limb pylon component therein, where the predetermined extension provides the prosthetic coupling height adjustability with respect to the prosthetic limb pylon to which it is adapted to be secured. Such prosthetic couplings may be supplemented with bushings inserted within the pylon mounting end to inhibit further pylon insertion beyond a desired depth.
