Cassius has been in control x-ray and the leg seems to be ok. This means that I have started rehabilitation. It will obviously be some time, but with a bit of luck we should be able to compeet in a couple of small dressage competitions in a month or so and maybe a jumping competition at the end of september.
I do not have the x-ray pictures, but I did take a few pictures of his leg the other day. The overgrowth of the bone is luckily primarily on the outside and hence there is still plenty of room for the tendons between the cannon bone and the metacarpal.
