Thesis

106 Part I Chapter 4 Figure 5 Sixty-year-old male patient with ulnar impaction (X-ray, A, arrow). First ulna shortening osteotomy was performed (images not shown). Two years later, OA of the distal radioulnar joint developed and arthroplasty of the DRUJ was performed (B). Fifteen months after arthroplasty the patient had pain again. Planar bone scintigraphy image (C), CT (D), and fused SPECT/CT (E) show increased uptake (arrows) in the radial fossa adjacent to the head of the prosthesis, consistent with mechanical overload or degeneration.
