An adjustment mechanism for an appendage elevation system, the adjustment mechanism comprising a housing, a clearance portion, first and second pin members telescopically received within the housing, a telescopic engagement mechanism mounted in the clearance portion and adapted to telescopically move the pin members, and a locking mechanism adapted to lock the pin members in a rigid position. One embodiment of the locking mechanism includes segments in the housing which restrict movement of the telescopic engagement mechanism. An alternative embodiment of the locking mechanism includes a spring button attached to a pin member which engages an aperture in the housing to restrict movement or the telescopic engagement mechanism. A further alternative embodiment of the locking mechanism includes a sleeve which engages the telescopic engagement mechanism to restrict movement. An appendage elevation system and a method for use of the adjustment mechanism are also disclosed.
