A transverse hole (21) is formed at the inner end of the slot, and having an inner diameter that is slightly greater than the diameter of the transverse rod. The assembly shaft is lockingly engaged to the transverse rod which is received in the transverse hole through the slot, such that the meniscal element is assembled on the bone anchor.
