A modular prosthesis 10 features at least one male-female fitting 30, with the female portion 36 being located on one end of one segment 16 of that prosthesis and the mating male portion 34 being located on one end of a second prosthesis segment 18, with at least the proximal part of the male-female fitting 30 having a taper 42, 44. Such a modular prosthesis 10 is especially useful for use as a femoral hip prosthesis having a modulus of elasticity compatible to the modulus of elasticity of bone and having a very close fit to the femoral canal 11 of the patient being treated. The two parts 34, 36 of that fitting 30 can be locked together by a locking mechanism in the form of a novel spacer 24 which also has a taper 56 which mates with the taper 42, 44 of the male-female fitting 30 described above. Multiple modular segments 16, 18, 20 can be assembled together so as to produce a prosthesis as required by the patient. |
