• femur
  • On the fifth day of admission the patient developed a spontaneous femur fracture. (njmonline.nl)
  • The ABC News investigation uncovered numerous reports of women experiencing sudden fractures in the femur bone in the leg while walking, stepping over doorways, standing, or doing other low-impact activities that resulted in a fall from a standing (or lower) height. (wordpress.com)
  • lesions
  • MRIs have shown evidence of Kernohan's notch from patients with traumatic head injury that are related to acute space-occupying lesions such as subdural hematoma, epidural hematoma, depressed skull fracture, or spontaneous intracerebral hematoma. (wikipedia.org)
  • metals
  • As can be expected, metals hold the highest values of fracture toughness. (wikipedia.org)
  • Comparatively, engineering ceramics have a lower fracture toughness, which leads to ease of cracking, but show an exceptional improvement in the stress fracture that is attributed to their 1.5 orders of magnitude strength increase, relative to metals. (wikipedia.org)
  • fixation
  • medical citation needed] Treatment options for internal fixation/repair of rib fractures include: Judet and/or sanchez plates/struts are a metal plate with strips that bend around the rib and then is further secured with sutures. (wikipedia.org)
  • occurs
  • Once infection occurs, these ulcerations can result in severe complications that lead to foot deformity, such as inflammation of the underlying bones, spontaneous bone fractures, and progressive degeneration of weight-bearing joints. (wikipedia.org)
  • injuries
  • Flail chest and first rib fractures are high-energy injuries and should prompt investigation of damage to underlying viscera (e.g., lung contusion) or remotely (e.g., cervical spine injury). (wikipedia.org)
  • common
  • The spontaneous dural cavernous fistula which is more common usually results from a degenerative process in older patients with systemic hypertension and atherosclerosis. (wikipedia.org)
  • chest
  • Rib fractures usually occur from a direct blows to the chest such as during a motor vehicle collision or from a crush injury. (wikipedia.org)
  • direct
  • They may be divided into low-flow or high-flow, traumatic or spontaneous and direct or indirect. (wikipedia.org)
  • For this reason, it is beneficial to think of an increase in strength (within the engineering alloys) as a direct decrease in fracture toughness, which is correlated with a lower ductility of the material. (wikipedia.org)
  • among
  • Just as the elastic properties of materials, like elastic moduli and strength, vary among material class, so too does the fracture toughness. (wikipedia.org)
  • material
  • In materials science, fracture toughness is a property which describes the ability of a material to resist fracture, and is one of the most important properties of any material for many design applications. (wikipedia.org)
  • The linear-elastic fracture toughness of a material is determined from the stress intensity factor ( K {\displaystyle K} ) at which a thin crack in the material begins to grow. (wikipedia.org)
  • A related concept is the work of fracture ( γ w o f {\displaystyle \gamma _{wof}} ) which is directly proportional to K I c 2 / E {\displaystyle K_{Ic}^{2}/E} , where E {\displaystyle E} is the Young's modulus of the material. (wikipedia.org)
  • leads
  • CONCLUSION: The sfx is a mutation of the GULO gene, which leads to ascorbic acid deficiency, impaired osteoblast cell function, and fractures in affected mice. (jax.org)
  • This relationship indicates, that within an alloy class an increase in strength leads to a decrease in fracture toughness regardless of the strengthening mechanism used. (wikipedia.org)
  • note
  • Of note is the fracture toughness of composites (made by combining engineering ceramics with engineering polymers) (in the zone of engineering alloys), which greatly exceeds the individual fracture toughness of the constituent materials. (wikipedia.org)
  • upper
  • In general, materials that are on the upper left most part of the diagram are used to design a system's failure against flow, because these materials yield before they are fractured. (wikipedia.org)
