| isotonic traction | Traction in which the amount of force does not change. (05 Mar 2000) |
|---|---|
| traction | <dentistry> The act of drawing or pulling the teeth. (08 Jan 1998) |
| traction alopecia | Circumscribed or diffuse loss of hair resulting from repetitive traction on the hair by pulling or twisting; also occurs after excessive application of hair "softeners" such as permanent wave solutions or hot combs. Alopecia marginalis is a form of traction alopecia. Synonym: traumatic alopecia. (05 Mar 2000) |
| traction atrophy | Bands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome. Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |
| traction diverticulum | A diverticulum formed by the pulling force of contracting bands of adhesion, occurring mainly in the distal oesophagus, from tuberculous hilar or mediastinal lymphadenitis. (05 Mar 2000) |
| traction epiphysis | A secondary centre of ossification at the site of attachment of a tendon. (05 Mar 2000) |
| external traction | A pulling force created by using fixed anchorage (e.g., a headcap or bed frame) outside the oral cavity; principally used in the management of midfacial fractures. (05 Mar 2000) |
| extraoral traction appliances | Extraoral devices for applying force to the dentition in order to avoid some of the problems in anchorage control met with in intermaxillary traction and to apply force in directions not otherwise possible. (12 Dec 1998) |
| abdominal aortic aneurysm | <surgery> A distended and weakened area in the wall of the abdominal aorta, more common in those who suffer from atherosclerosis. Symptoms include sudden, severe abdominal pain with radiation to the back. (27 Sep 1997) |
| ampullary aneurysm | A saclike bulging on one side of an artery. Synonym: ampullary aneurysm. (05 Mar 2000) |
| aneurysm | <anatomy, surgery> A sac formed by the dilatation of the wall of an artery, a vein or the heart. The physical signs of arterial aneurysm are the formation of a pulsating tumour and often a bruit (aneurysmal bruit) heard over the swelling. Sometimes there are symptoms from pressure on contiguous parts. Origin: Gr. Aneurysma = a widening (18 Nov 1997) |
| aneurysm by anastomosis | A mass of dilated anastomosing vessels that produce a pulsating tumour usually in a superficial position. (05 Mar 2000) |
| aneurysm, dissecting | Splitting or dissection of an arterial wall by blood entering through an intimal tear or by interstitial haemorrhage. It is most common in the aorta. (12 Dec 1998) |
| aneurysm, false | An aneurysm in which the entire wall is injured and the blood is contained by the surrounding tissues, with eventual formation of a sac communicating with the artery or heart. (12 Dec 1998) |
| aneurysm, infected | Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms. (12 Dec 1998) |
