Paget–Schroetter disease (which evolved from a venous thoracic outlet syndrome) is a form of upper extremity deep vein thrombosis (DVT), a medical condition in which blood clots form in the deep veins of the arms. These DVTs typically occur in the axillary and/or subclavian veins. [1]
Paget’s disease of bone is a chronic disorder characterized by abnormal bone remodeling. The pelvic brim sign arises due to excessive bone resorption due to increased osteoclastic activity in the early stages of the disease leads to localized bone loss, as well as excessive bone formation during the later stages of the diseases.
Paget's disease may refer to several conditions described by Sir James Paget, surgeon and pathologist: Paget's disease of bone (most common use of the term "Paget's disease") Paget's disease of the breast; Paget–Schroetter disease; Paget's abscess; Extramammary Paget's disease (EMPD)
Radiograph (x-ray) with the animal under Anesthesia and if necessary, a Radiocontrast agent (contrast dye) may be used in the joints before undergoing the test. Force plate analysis, where a pressure plate on the floor reads the distribution of weight by the dog/cat to detect a favouring of one limb over the others.
Blade of grass sign (also known as flame sign [1]) is a radiologic sign referring to the lytic fronts seen in the leading edge of the long bone in Paget's disease. [2] It is usually seen as a wedge shaped area of radiolucency in the diaphysis of long bone. [1]
Paget's disease of bone is the second most common metabolic bone disorder, after osteoporosis. [37] The overall prevalence and severity of Paget's disease are decreasing; the cause for these changes is unclear. [38] Paget's disease is rare in people less than 55 years of age, [7] and the prevalence increases with age. [38]
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Sir James Paget described median nerve compression at the carpal tunnel in two patients after trauma in 1854. [120] [121] The first was due to an injury where a cord had been wrapped around a man's wrist. The second was related to a distal radial fracture. For the first case Paget performed an amputation of the hand.
