Modified patient positioning using a standard-sized C-arm before (left image) and after (right image) sterile draping: Hip and knee are flexed to allow the foot being placed in a plantigrade position on the operation table, parallel to the floor and detector of the fluroscope. Thereby easy manouverability around the foot is possible for adjunct procederes (e.g. DMMO) without moving the C-arm. By performing an external rotation in the hip a true lateral view is attainable. The oblique view is obtained by slight internal rotation in the hip joint. Note the drape under table radiation protection
