ABSTRACT:
A fixture permitting adjustment of the position and axial alignment of a prosthesis is characterized by a first attachment member associated with a socket attached to the wearer's stump, and by the fixture's ability to be adjusted without the necessity of removing the socket from the wearer's stump. A second attachment member is operatively attached to the prosthesis, and adjustable attachment means operatively connects the second attachment member to the first attachment member. The adjustable attachment means includes a central bolt member which may be accessed for adjustment without removing the socket from the wearer. The bolt member preferably extends through a rectilinear central opening in the first attachment member, providing a range of selectable lateral positions of the second attachment member with respect to the first attachment member. The adjustable attachment means also preferably includes a frustoconical member disposed between the first and second attachment members, and auxiliary adjustment members operatively engaged between the second attachment member and the frustoconical member to permit the axial alignment of the second attachment member to be adjusted with respect to the first attachment member.
