A stress fracture is a fatigue-induced bone fracture caused by repeated stress over time. Instead of resulting from a single severe impact, stress fractures are the result of accumulated injury from repeated submaximal loading, such as running or jumping.
intra articular comminuted fracture of base of first metacarpal: axial load along the metacarpal causing splitting of the proximal articular surface: Rolando's fracture at Wheeless' Textbook of Orthopaedics online Runner's fracture: Running: stress fracture of distal fibula 3–8 cm above the lateral malleolus: repeated axial stress on fibula
In a 2001 survey of stress fractures in theropods, one toe bone from indeterminate ornithomimids out of fifteen examined was found to have a stress fracture. None of the eight finger bones examined was found to have a stress fracture. [11] Ornithomimus and Archaeornithomimus showed a significantly lower number of stress fractures than ...
An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. [2] A bone fracture may be the result of high force impact or stress , or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis , osteopenia , bone cancer , or osteogenesis imperfecta ...
Spondylolysis is a defect or stress fracture in the pars interarticularis of the vertebral arch. [1] The vast majority of cases occur in the lower lumbar vertebrae (L5), but spondylolysis may also occur in the cervical vertebrae. [2]
A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis).
This stage appears on MRI as an isolated bone marrow edema pattern without a fracture line and is called stress reaction. Then, periosteal new bone forms and may be visible on radiography. Full cortical fractures occur if the repetitive stress continues. Only timely detection and appropriate management can interrupt this sequence. [1]
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).
