The staple comprises a top having four downwardly depending legs adjacent to its four corners. Two of the downwardly depending legs on the same side of the top are spaced inwardly from the corners relative to the remaining two legs so as to be transversely offset therefrom. The offset legs avoid the risk of splitting the bone when the staple bridges the bone "grain". In other words, the two legs will enter different cleavage planes of the bone rather than the same cleavage plane. Projections are provided on the underside of the top of the staple to aid in frictionally gripping and retaining a tendon or equivalent tie being held by the staple to a bone.
