The two broad categories of blowout fractures are open door and trapdoor fractures. Open door fractures are large, displaced and comminuted, and trapdoor fractures are linear, hinged, and minimally displaced. [4] The hinged orbital blowout fracture is a fracture with an edge of the fractured bone attached on either side. [5]
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.
Due to the fault's proximity to populated areas, supershear earthquakes can have devastating effects. [27] The length of fault running 260 km (160 mi) from 19.2°N to 21.5°N, on the Meiktila segment, is designated a seismic gap due to the absence of major earthquake ruptures since at least 1897. At least 2 m (6 ft 7 in) of slip has accumulated ...
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
Tibial plateau fractures may be divided into low energy or high energy fractures. Low energy fractures are commonly seen in older females due to osteoporotic bone changes and are typically depressed fractures. High energy fractures are commonly the result of motor vehicle accidents, falls or sports related injuries.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging. [1]
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 ...
