Gymnast’s wrist is an overuse injury among gymnasts with open growth plates caused by the repeated compression and loading of wrists during practice and competition.
There are two bones in the forearm: the radius and the ulna. Each of these bones have growth plates, softer areas of cartilage where bone growth takes place. Until the growth plates harden into solid bone, they are especially vulnerable to injury. Gymnast’s wrist is a stress fracture of the growth plate of the radius.
If caught early, gymnast’s wrist can heal with rest and immobilization. But ignoring wrist pain and continuing to strain the wrists can lead to more serious injury. For instance, continuing to practice with gymnast’s wrist can cause the radius to stop growing while the ulna continues to grow, a serious and painful condition that may require surgery.
Gymnast’s wrist is also sometimes accompanied by other injuries, such as a tear of the triangular fibrocartilage complex (TFCC), the cartilage that supports and stabilizes the wrist.
