An occult fracture is a fracture that is not readily visible, generally in regard to projectional radiography ("X-ray"). Radiographically, occult and subtle fractures are a diagnostic challenge. Radiographically, occult and subtle fractures are a diagnostic challenge.
Both anterior and posterior fat pad signs exist, and both can be found on the same X-ray. In children, a posterior fat pad sign suggests a condylar fracture of the humerus. In adults it suggests a radial head fracture. In addition to fracture, any process resulting in an elbow joint effusion may also demonstrate an abnormal fat pad sign.
Scaphoid fractures are often diagnosed using plain radiographs and multiple views are obtained as standard. [9] However, not all fractures are apparent initially. [7] In 1/4 of cases, the clinical examination suggests a fracture, but the X-ray does not show it, even though there is indeed a fracture. [10]
Diagnostic imaging may include ultrasound, plain radiography (x-ray imaging), Computed tomography scan (CT), and magnetic resonance imaging (MRI). [2] [4] A fat pad sign may be present on diagnostic imaging and may indicate a radial head fracture. [5] A diagnosed radial head fracture can be classified according to the Mason-Johnston system. [3]
A Lisfranc injury, also known as Lisfranc fracture, is an injury of the foot in which one or more of the metatarsal bones are displaced from the tarsus. [1] [2]The injury is named after Jacques Lisfranc de St. Martin, a French surgeon and gynecologist who noticed this fracture pattern amongst cavalrymen in 1815, after the War of the Sixth Coalition.
In situations where a hip fracture is suspected but not obvious on x-ray, an MRI is the next test of choice. If an MRI is not available or the patient can not be placed into the scanner a CT may be used as a substitute. MRI sensitivity for radiographically occult fracture is greater than CT.
Two insurance companies have asked a court to block a $19.7 million claim by owners of more than two dozen forged Jean-Michel Basquiat paintings that were seized during an FBI raid at the Orlando ...
Projectional radiography ("X-ray") is the first imaging technique of choice in hip pain, not only in older people with suspected osteoarthritis but also in young people without any such suspicion. In this case plain radiography allows categorization as normal hip or dysplastic hip , or with impingement signs, pincer, cam, or a combination of both.
