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.

Bone anchor

The invention describes a graft suspension device for suspending a ligament in a bone hole. The suspension device comprises a first loop and second loop suspended from an anchor and has a cradle at the opposite end of the loop to the anchor. Ligament grafts (not shown) are looped over the cradle and loose ends may be pulled by finger loops whereby the surgeon can adjust the distance of the cradle from the anchor thereby tensioning the grafts as desired.
