Abstract

The instant device is made up of a guide wire component, a proximal wedge component and a distal wedge component with the proximal wedge component having a side with an inclined medial face, two suture grooves on this side above its inclined face, a stop face inclined obtusely to and outwardly from its inclined face and a guide wire hole through its head extending through its length and terminating in its inclined face as well as serrated bone biting edges located on its opposite side and with the distal wedge component having two suture thread holes in its medial face and at its base and a guide wire hole on the side where its inclined face is found below and between its two suture thread holes and at its base, and a stop face inclined obtusely and inwardly from its inclined face as well as a beveled bone biting edge at its top such that simultaneous application of downward pressure on the head of the proximal wedge component and upward pressure on suture thread threaded through suture thread holes in the distal wedge component, after separation of those two components from the guide wire component subsequent to these two components having been guided along the guide wire previously placed into a hole previously drilled in bone, in the drilled hole in bone serves to firmly and permanently lodge these two components within the drilled hole in bone in order to permit the suture thread to be then tied to soft tissue to be thereby firmly anchored to the bone.
