The long and short axis of the sesamoid bone. (a) The long axis of the medial distal sesamoid bone (the longest distance of the medial distal sesamoid bone). (b) The short axis of the medial distal sesamoid bone (the shortest distance of the medial distal sesamoid bone). (c) The long axis of the lateral distal sesamoid bone. (d) The short axis of the lateral distal sesamoid bone. (e) The long axis of the medial proximal sesamoid bone. (f) The short axis of the medial proximal sesamoid bone.
