is this a chicken drum-stick?? noope....it is a sketchy outline of dove's left-hind leg bone called the Tibia. unfortunately the sketch is too high on the 'paper' but sorry folks I'm in no mood to redo it.
this is a normal tibial bone for canines. the ACL, surprisingly small, is one ligament that attatches this bone to the one above it-- the size of these thumbnails is really too small to give alot of detail. (just think of your own knee and there is a legbone beneath and a legbone above- this is the canine hind leg below the knee)
what is important here is the slope of the Tibial head on the right side. when the ACL is completely ruptured in canines the two leg bones--interposed by the knee and ligaments--can no longer keep the top bone from sliding down the right slope of the Tibia.........ooooouch.
