    摘要: The invention describes a bone anchor 76 comprising a head region 94 and supporting legs 78 and a method for soft tissue-bone grafting using the said bone anchor 76. A hole 84 is drilled through cortical bone 82 forming a socket 70 in a cancellous bone 90, and the bone anchor 76 is inserted therein thereby trapping ligaments 88a and 88b between the radially outermost portion of the anchor 76 and the inside surface of the socket 70. An optional expansion peg (not shown) is inserted into a hole 86 within the bone anchor 76, thereby causing the proximal ends of the legs 70 of the bone anchor 76 to expand radially causing the ligaments 88a and 88b to closely abut the cancellous bone 90 thereby encouraging the grafting process.
