先给你一点应力骨折的文字资
what is a stress fracture?
a stress fracture is a common overuse injury most often seen in athletes. usually, a fracture, or broken bone, is caused by an acute event, such as a car crash or a fall. when this is the case, the bone experiences a very high force that causes the stress fracture.
a stress fracture occurs when the forces are much lower, but happen repetitively for a long period of time； these injuries are also known as \"fatigue fractures.\" stress fractures are commonly seen in athletes who run and jump on hard surfaces, such as distance runners, basketball players, and ballet dancers.
a stress fracture can occur in any bone, but is commonly seen in the foot and shin bones. they rarely occur in the upper extremity because the weight of your body is not supported by your arms as it is in your legs.
how is a stress fracture diagnosed?
physical examination and history are important in diagnosing stress fractures. because these overuse injuries have a typical course and common physical findings, the history and examination can be critical in the diagnostic evaluation. x-rays usually do not show a stress fracture, but they may show evidence of bone attempting to heal around the stress fracture. further studies, including an mri or bone scan may be necessary if the diagnosis is unclear or if the problem does not resolve with treatment.
