Abstract
A technique and reconstruction system for ligament employing a button/loop construct with a drill pin. The drill pin has a shaft with a proximal and a distal end. A pin tip provided at the distal end of the shaft has a width greater than the shaft diameter. The pin tip helps cut a wider tunnel for fixation of ligaments/grafts in reconstructive surgeries. The shaft of the drill pin is provided with a laser marks for measurement of intraosseous length.
Claims8
A drill pin comprising:
- a shaft having a distal end and a proximal end,
- wherein the proximal end has an eyelet, and wherein the distal end has a tip portion with cutting edges, the tip portion with cutting edges having an increased diameter relative to the rest of the shaft.
The drill pin of claim 4, wherein the plurality of laser markings are spaced at a predetermined length from the distal end.
A method of graft fixation, comprising:
- (i) drilling a tunnel through bone using a drill pin, the drill pin having a shaft provided with laser marks, a proximal end provided with an eyelet, and a distal end provided with cutting edges, the distal end having an increased diameter relative to the rest of the shaft;
- (ii) securing a button/loop construct with an attached graft to the drill pin by passing strands from the button/loop construct through the eyelet in the drill pin;
- (iii) passing the drill pin and the suture/button construct with the attached graft through the tunnel;
- and
- (iv) securing the button to the cortex of the bone once the button exits the tunnel.
