Screw Fixation and Autogenous Bone Graft for an Irreducible Distal Ulna Fracture Associated with Distal Radius Fracture

Distal ulna fractures often occur with distal radius fractures, and their treatment method is still controversial. We considered reduction of the distal radio-ulnar joint (DRUJ) surface the most important factor when treating distal ulna fractures accompanied by residual dislocation. We herein presented a patient with a distal ulna fracture accompanied by dislocation of the DRUJ surface in whom an autogenous bone fragment collected from the radius was grafted onto the ulnar bone defect after open reduction and Herbert screw fixation. In this technique, the bone fragment was supported through the medullary cavity by inserting a Herbert screw, which was less likely to cause irritation between the screw and surrounding tissue, because the screw was almost entirely present in the bone. In addition, an autogenous bone graft from the same surgical field may be less invasive than that from another region.
