[sumo] Spondylolysis (back stress fracture)

[O'Flaherty, Brian]

I haven't been involved in the rights or wrongs of Asashoryu's soccer game 
up to this point but I think playing a 'non-twisting' sport (if that defence
even holds any water) would be seen as exposing yourself to unnecessary risk
and that's quite apart from the behavioural duties of a yokozuna.  
I'm a big Asa fan but I can't really defend him in this case.  

>I have done a fleetingly quich investigation of back stress fracture,

>I would include sumo, can be different from the angle in non twisting

>that a stress fracture resulting from a twisting sport might not be 
>exacerbated by activity in a nontwisting sport?   Hmm.
