摘要：A femoral component for a hip replacement joint having a tapered collarless

stem for being cemented in a medullary canal. The proximal portion of the stem has ataper and the distal segment is generally circular in cross-section and has a length equalto or greater than the proximal portion. The component can be made in two separatepieces and can be coupled in the metaphysical area of the femur. In one embodiment, atthe proximal end of the stem, there is a pronounced laterally projecting heel adapted toextend into the greater trochanter of the femur of the femur into which it is to be filled.Thus, the distal facing part of the heel can provide a lateral portion which is greater thanthat of known collarless stems and which is particularly adapted to resist torque. In orderto fit the femoral component in the medullary canal, it is necessary to broach themedullary canal so that there is a cavity within the greater trochanter.
