David C. Rehak, MD:
… A gymnast’s wrist is inclined to injuries because many routines (1) place the body’s weight on the wrist while bending it backwards, and (2) often require fast, jolting movements to the wrists and hands. This results in injuries that are both acute, such as fractures, dislocations and sprains, and chronic (long-term).
Most acute gymnastic injuries are treated like any other sport injuries, however, two chronic injuries, dorsal wrist impingement and distal radial stress fractures, require specific treatment. …

The issue for coaches is whether or not to encourage athletes with chronic pain to use dorsal-wrist-block supports like Tiger Paws or the Ezy ProBrace.
Conventional wisdom is to delay using wrist bracing as long as possible. To take them off when possible. And to specifically strengthen the wrists to handle the impact.
Some girls simply like colourful accessories. 😀
