Occult fracture. 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. They may be divided into 1) high energy trauma fracture, 2) fatigue fracture from cyclical and sustained mechanical stress, and 3 ...
A subtle radial head fracture with associated positive sail sign. The fat pad sign, also known as the sail sign, is a potential finding on elbow radiography which suggests a fracture of one or more bones at the elbow. It is may indicate an occult fracture that is not directly visible. Its name derives from the fact that it has the shape of a ...
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.
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]
Orthopedic. A supracondylar humerus fractureis a fracture of the distalhumerusjust above the elbow joint. The fracture is usually transverse or oblique and above the medial and lateral condyles and epicondyles. This fracture pattern is relatively rare in adults, but is the most common type of elbow fracture in children.[1]
A coccyx fracture is a fracture of the coccyx, commonly called a broken tailbone or ‘puzzle fracture.’. The coccyx is located at the base of the spine, under the sacrum. It is the last section of the ape vertebral column. Most commonly in humans it comprises 3 to 5 fused (or, more rarely, separate) vertebrae, and is approximately 4 to 10 cm ...
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.
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.
