Abstract
A system for adjusting the angle between a pylon and prosthetic foot in either or both of the medial/lateral plane or the anterior/posterior plane by placing at least one wedge between the pylon and the prosthetic foot. A barrel nut mounted in the lower end of a prosthetic pylon mates with a bolt extending from the prosthetic foot to secure the foot to the pylon. The angle of the barrel nut is adjusted in the anterior/posterior plane so that a threaded bore of the barrel nut is aligned with the bolt as its angle varies according to the angle of the wedge positioned between the pylon and prosthetic foot. For the same reason, the position of the barrel nut in the medial/lateral plane may be adjusted.
