Tihomil Z, Mario K, Bore B, et al. - Given a particular significance of aseptic necrosis of the lunate bone among numerous diseases which reduce the functional ability of the hand, researchers here investigated the smallest amount of loading on the lunate bone obtained by gradually shortening the radius in different ulnar variants as the potential treatment of Kienböck's disease. They conducted the research on anatomic preparations of 20 upper extremities utilizing only the distal part of the forearm and hand, placing them in exactly defined positions. Insertion of a Fuji Prescale film was done in the open radiocarpal joint to determine pressure after compressing axially by changing the length of the forearm in four stages by the gradual shortening of the radius. Outcomes suggest the possibility of achieving pressure relief on lunatum with shortening of the radius depending on the anatomical variation of the ulnar bone. They identified that for healing, pressure distribution in the distal radiocarpal joint is vital and that shortening of the radius relieves the pressure on the lunate bone. The preoperative ulnar variant determines the exact type of surgery and the amount of radial osteotomy.
