Abstract: 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.
