Picture 1 - Triagular Fibrocartilage Complex (TFCC), wrist structure situated between forearm and wrist bones

Picture 2 - Impaction of the ulna against the wrist bone (lunate) with consequential damage of the TFCC

Picture 3 - X rays image demonstrating positive ulna variance and abutment of ulna against the lunate bone

Picture 4 - Ulnar shortening osteotomy - surgical shortening of the ulna leads to decompression of the ulnar wrist corner

Picture 5 - X rays before and after 6mm of ulna shortening; better bone alignment predictably leads to symptom improvement

Picture 6 - Splint required for min 6 weeks after the ulna shortenong osteotomy
