Ex Hawthorn player told me today it's a Brown type break will be 18 months.
A girl I know did a spiral fracture of her leg when she twisted quickly, but her foot was pinned. Very slow healing and a massive pins to hold things in place. Took her ages to recover.
The reports seem to indicate that it was a similar torsional break action, and if so the damage could be similarly nasty. Much worse (as the damage goes up the bone/s) than a simple clean lateral break/fracture.
