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