Injury may also occur from a distraction force applied to the volar forearm or wrist. Finally, tears of the TFCC are frequently found by patients with distal radius fractures. [7] Perforations and defects in the TFCC are not all traumatic. There is an age related correlation with lesions in the TFCC, but many of these defects are asymptomatic ...
There is an increased risk of interosseous intercarpal injury if the ulnar variance (the difference in height between the distal end of the ulna and the distal end of the radius) is more than 2mm and there is fracture into the wrist joint. [5] Triangular fibrocartilage complex (TFCC) injury occurs in 39% to 82% of cases.
The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up. [1] Once rotated, the clinician pushes down on either the wrists or the elbow, and the patient is instructed to resist the downward pressure.
The Hess test or Rumpel-Leede test is a medical test used to assess capillary fragility. [1] It is also called the Tourniquet test . To perform the test, pressure is applied to the forearm with a blood pressure cuff inflated to between systolic and diastolic blood pressure for 10 minutes.
Traumatic tears are usually radial or vertical in the meniscus and more likely to produce a moveable fragment that can catch in the knee and therefore require surgical treatment. [citation needed] A meniscus can tear due to an internally or externally rotated knee in a flexed position, with the foot in a flexed position. [5]
The tear test (e.g. Kahn tear test) provides a semi-quantitative measure of toughness in terms of tear resistance. This type of test requires a smaller specimen, and can, therefore, be used for a wider range of product forms. The tear test can also be used for very ductile aluminium alloys (e.g. 1100, 3003), where linear elastic fracture ...
Chondrocalcinosis can be visualized on projectional radiography, CT scan, MRI, ultrasound, and nuclear medicine. [1] CT scans and MRIs show calcific masses (usually within the ligamentum flavum or joint capsule), however radiography is more successful. [1]
The McMurray test is named after Thomas Porter McMurray, [2] a British orthopedic surgeon from the late nineteenth and early twentieth century who was the first to describe this test. The description of the test has since been altered from the original by various authors. [3] Most commonly, varus and valgus stress to the knee is added. These ...
