ABSTRACT:
A modular prosthesis features at least one male-female fitting, with the female portion being located on one end of one segment of that prosthesis and the mating male portion being located on one end of a second prosthesis segment, with at least the proximal part of the male-female fitting having a taper. The two parts of that fitting can be locked together by a locking mechanism in the form of a novel spacer which also has a taper which mates with the taper of the male-female fitting described above. Multiple modular segments can be assembled together so as to produce a prosthesis as required by the patient.
