Patent ID: 7708781

Claim:
A proximal radioulnar joint prosthesis, comprising: a radial brace member including a rod defining a longitudinal axis and distal and proximal ends; and a ball at the proximal end of said rod; an ulnar brace member having an upper end and a lower end and including a downwardly-extending elongated portion defining an elongated abutment surface shaped to abut and conform to the outer surface of the human ulna bone near its proximal end; a projection from said downwardly-extending elongated portion defining a downwardly opening curved recess including means for receiving and supporting said ball for rotation; and means for mounting said ulnar brace member on a human ulna near the proximal end of the ulna so as to place the projection that defines the downwardly opening curved recess in the proximal radial notch of the human ulna while leaving the proximal ulna intact.
