摘要：
A device for creating a cavity in a bone, said cavity having a cross-section which has a generally triangular profile having a first side generally parallel with an axis of the bone and a second side forming an acute angle with the first side, and contiguous with a pre-existing conical cavity, includes a shaft having a longitudinal axis and including a proximal portion and a distal portion, wherein the proximal portion has a larger cross section perpendicular to the longitudinal axis than the corresponding cross section of the distal portion, and a broach non-rotationally supported by the shaft and having a first cutting side supported at the acute angle relative to the longitudinal axis of the shaft, wherein the distal portion of the shaft is formed to include witness marks which when registered with an indicator after advancing the shaft facilitate selection of an appropriately sized prosthesis component.
