Avulsion fracture

Highly trained athletes can overcome this neurological inhibition of strength and produce a much greater force output capable of breaking or avulsing a bone.

Tibial tuberosity avulsions occur most often in teenagers that engage in a large amount of sporting activities, and many studies [which?]

If the fracture is small, it is usually sufficient to treat with rest and support bandage, but in more severe cases, surgery may be required.

Open reduction (using surgical incision) and internal fixation is used when pins, screws, or similar hardware is needed to fix the bone fragment.

[citation needed] In 2001, Bruce Rothschild and other paleontologists published a study examining evidence for tendon avulsions in theropod dinosaurs.
