In sports such s golf nd tennis, the hmte one cn rek if is sujected to high externl force, such s from the hndle of rcquet or clu. At our hospitl we tke X-ry imges of the hmte one from two directions: n xil imge through the crpl tunnel nd n imge t the se of the hmte hook (conventionl method). While the conventionl method mkes it esy to crete imges of the se of the hmte hook, the ptient my suffer pin during imge-tking ecuse the hmte one is pulled to cuse rdil flexion. We therefore investigted method of imging tht would crete three-dimensionl computed tomogrphy (3DCT) imges of the se of the hmte hook in which the ptient would only hve to only rotte the wrist externlly nd elevte the forerm without ny rdil flexion. Our results suggest tht it is possile to otin imges of the se of the hmte hook s cler s those cquired using the conventionl method with the ptient in comfortle nd pinless position tking imges t n externl rottion ngle of 50.3 nd forerm elevtion ngle of Key word: hmte hook *Proceeding uthor
