TIBIAL PART OF A KNEE PROSTHESIS, IN PARTICULAR A UNICOMPARTMENTAL KNEE PROSTHESIS, COMPRISING A TIBIAL TRAY

摘要

part of a prosthetic knee joint, including unicompartimentaire tibial plateau, with a face (3) having a lower or distal edge, bounded by a ring (6) having at least one lateral portion (9) and which protrudes at least one plot (4; 5) anchor of destiny to be anchored in the tibia.the at least one plot (4, 5) comprising at least a part (14) forming the stem axis (30) with a longitudinal and a head part (15) forming part of the stem and the head portion defining between them an interface (25) which corresponds to the cross section of the plot, perpendicular to the longitudinal section of said anchor.who is at the level of the point (s) (22) of the lateral surface of the plot, which is or are the most distant from the axis (s) (30), the distance being measured at right angles to the axis (30), characterised in that the cross section (dl) in the the stem and the base section (25) support are mutually staggered.
