Forearm transplantation osteosynthesis using modified ulnar shortening osteotomy technique

One of the challenges of forearm-level hand transplantation surgery is the achievement of osseous union of the ulna given the substantial soft tissue dissection, the use of immune modulating medications, and the diaphyseal level of osseous coaptation. Modification of the conventional surgical technique for an elective ulnar shortening osteotomy provides the advantages of precise osteotomy alignment, a large contact surface oblique osteotomy, and lag screw and compression plating technique. A step-by-step description of the developed modification is provided with a case example.
