Stress fractures can be described as small cracks in the bone, or hairline fractures. Stress fractures of the foot are sometimes called "march fractures" because of the injury's prevalence among heavily marching soldiers. [2] Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula ...
March fracture is the fracture of the distal third of one of the metatarsal bones occurring because of recurrent stress. It is more common in soldiers, but also occurs in hikers, organists, and other people whose duties entail much standing (such as hospital doctors).
Stress injuries (stress fractures and stress reactions) of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. [18] The onset of the observed cervical fractures in sports injury were likely due to continued momentum that transferred loads superiorly through the neck, which exacerbates injuries to ...
With surface structure size inversely related to stress concentration factors, PSB-induced surface slip can cause fractures to initiate. These steps can also be bypassed entirely if the cracks form at a pre-existing stress concentrator such as from an inclusion in the material or from a geometric stress concentrator caused by a sharp internal ...
The initiation site for fracture in these materials can often occur at inorganic dust particles where the stress exceeds critical value. Under standard linear elastic fracture mechanics, Griffiths law can be used to predict the amount of energy needed to create a new surface by balancing the amount of work needed to create new surfaces with the ...
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress.The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid.
Life with other cats can sometimes get stressful! Speaking of stress pooping—here is the story of a kitten who “adopted us.” We also had an intact male cat dropping by for some food.
Computed Tomography (CT): While less commonly used, CT scans can provide detailed information about bone structure and may be helpful in surgical planning. Differential diagnosis is important, as several conditions can mimic Freiberg disease, including stress fractures of the metatarsal, Morton's neuroma, and various forms of arthritis.
