Gymnasts wrist does not mean she can’t be a successful gymnast, and having it once does mean it will continue to happen.
The condition usually stems from one of the following areas -
1. Not enough strength in the wrists, forearms, hands etc
2. Poor technique on skills - ie doing lots of handstands and back handsprings with turned out hands.
3. Unbalanced training - ie doing too many skills, repetitions, on the hands in a row.
4. Growth issues or a big jump in training hours or training intensity.
Sure, some kids are more prone to it than others, but it still generally takes one of the issues above to trigger it. The big thing about these issues is that they are generally fixable, treatable, changeable. If the physio and coaches can identify why it has happened, they can take steps to reduce the chances of it happening again in the future.
When you say it will take her out of training for 2-3 months, does that mean she won’t be training at all? If we have a child with such an injury they would still be training. There is still so much they can do - conditioning, flexibility, active flex, leaps, jumps, turns, dance, aerials, saltos, Twisting, Work in spotting belts, vault drills, etc etc.
That way they don’t lose all the strength, flexibility and skills they have worked so hard to attain and it makes them less prone to reinjury. Taking a big break from training will increase the chances of injury upon return.
Injury does not have to mean a delay in development. Often when we have a kid with an injury it does the total opposite and allows them to make huge strides in their gymnastics development, because they will be able to focus a lot on particular skills and spend more time developing them, as they can’t do other things.
