Miki apparently has a dislocated shoulder. That is not good news. Seems to me she dislocated that shoulder two years ago. Once you dislocate a shoulder joint, you are in danger of dislocating it again. And if it happens again, then the danger of it becoming a chronic injury is very great because the tendons that hold the shoulder in place become stretched out and they no longer function properly. Jumping and spinning puts stress on the shoulder joint and can easily pull it out.
That it happened in competition is not a good sign.
