Thanks very much Physiobob, I suspected as much, but you have really put it in context for me...
I should have known when the NHS consultant laughed at the special semi-adhesive bandage that the Austrians had beautifully wrapped my leg in after the injury and his astonishment at the fact they had done anMRI to evaluate the damage to the soft tissues at all... not to mention the look my Aircast got
It was indeed a pronation-lateral rotation injury although the malleolus is intact, so the deltoid ligament must have ben ruptured - I do Tae Kwon Do, so need to be back to as near normal as possible
really appreciate your help - thanks
all the best
