Apparatus for treating a bone fracture, the apparatus including an anchoring tube having a hollow elongated shaft adapted for disposition in a hole formed in a bone and having a distal end, a proximal end and a lumen extending therebetween, and a substantially planar plate mounted to the proximal end of the hollow elongated shaft and adapted for disposition against the outer surface of the bone; wherein the plate has a top surface and a bottom surface, and further wherein the bottom surface of the plate is convex, such that when the anchoring tube is disposed in a hole formed in a bone and is rotated about the longitudinal axis of the hollow elongated shaft, the convex bottom surface of the plate maintains supporting contact with the outer surface of the bone. |

1. A method, for treating a bone fracture, the method comprising:
providing an apparatus comprising:
an anchoring tube comprising a hollow elongated shaft adapted for disposition in a hole formed in a bone and having a distal end, a proximal end and a lumen extending therebetween, and a substantially planar plate mounted to the proximal end of the hollow elongated shaft and adapted for disposition against the outer surface of the bone;wherein the hollow elongated shaft comprises at least two diametrically-opposed holes extending therethrough;a suture assembly; anda buckle holder for holding a buckle while a suture is secured to the buckle, wherein the buckle has two holes therein and a slot connecting one of the holes to an end of the buckle, the buckle holder comprising a body having a proximal end, a distal end, a top surface and a bottom surface, a pair of holes extending from the top surface to the bottom surface, a buckle seat adjacent the distal end and extending proximally, and a vertical slot opening on the distal end and extending proximally, the vertical slot extending between the top surface and the bottom surface, the buckle holder being sized so that the buckle seat can receive the buckle, with the two holes in the buckle being aligned with the two holes in the buckle holder;
forming a hole in the bone; positioning the hollow elongated shaft of the anchoring tube in the hole in the bone; and extending the suture assembly through a bone fragment, through at least one of the diametrically-opposed holes in the hollow elongated shaft, and through the lumen of the anchoring tube, the suture assembly securing the bone fragment to the anchoring tube under tension, thereby securing the bone fragment to the bone receiving the anchoring tube. |
