Claim:
1. A height measuring system comprising: a prosthetic humeral stem trial implant; a prosthetic humeral stem implant component; and a height measuring tool including: wherein movement of the sliding member in a distal direction in relation to the body member causes corresponding movement of the height reference member in the distal direction when the sliding member is engaged to the height reference member and the height reference member is in an unlocked state, wherein the height reference member includes at least one knob configured to increase or decrease frictional engagement between the height reference member and the body member, wherein movement of the sliding member in the distal direction in relation to the body member does not cause corresponding movement of the height reference member in the distal direction when the sliding member is engaged to the height reference member and the height reference member is in a locked state.
