| malgaigne fracture | <radiology> Two vertical fractures involving one side of the pelvic ring, one fracture anterior to the acetabulum, usually through the pubic ramus, one fracture posterior to the acetabulum, usually through the ilium, separation of the SI joint may occur instead usually the result of direct trauma (12 Dec 1998) |
| Malgaigne's amputation | Amputation of the foot in which only the astragalus is retained. Synonym: Malgaigne's amputation. (05 Mar 2000) |
| Malgaigne's fossa | A space bounded by the superior belly of the omohyoid muscle, anterior border of the sternocleidomastoid, and posterior belly of the digastric; it contains the bifurcation of the common carotid artery. Synonym: trigonum caroticum, fossa carotica, Gerdy's hyoid fossa, Malgaigne's fossa, Malgaigne's triangle, superior carotid triangle. (05 Mar 2000) |
| Malgaigne's hernia | Infantile inguinal hernia prior to the descent of the testis. (05 Mar 2000) |
| Malgaigne's luxation | Subluxation of the radial head within the elbow joint is also referred to as nursemaid's elbow. This orthopaedic condition is seen commonly in toddlers who may be lifted up by outstretched arms. Instability of the radial head leads to subluxation. The child with nursemaid's usually has their arm in hanging in extension at their side and any attempted movement of the elbow joint is met with pain. (27 Sep 1997) |
| Malgaigne's triangle | A space bounded by the superior belly of the omohyoid muscle, anterior border of the sternocleidomastoid, and posterior belly of the digastric; it contains the bifurcation of the common carotid artery. Synonym: trigonum caroticum, fossa carotica, Gerdy's hyoid fossa, Malgaigne's fossa, Malgaigne's triangle, superior carotid triangle. (05 Mar 2000) |
| Malherbe's calcifying epithelioma | A tumour composed of cells resembling those of the hair matrix, which undergo 'mummification' and may calcify. It is a relatively uncommon tumour, which may occur at any age from infancy. The majority of patients are under 20, and females are affected more than males. The lesion is usually a solitary deep dermal or subcutaneous tumour 3-30 mm in diameter, situated in the head, neck, or upper extremity. (12 Dec 1998) |

| mali | A country in western africa, east of mauritania and north of sudan. Its capital is bamako. Its earlier names give a clue to its african and overseas connections: 1904-1920 it was known as upper senegal-niger; prior to 1958, as french sudan; 1958-1960 as the sudanese republic and 1959-1960 it joined senegal in the mali federation. It became an independent republic in 1960 but the government is at present in transition. Mali was the name of a former empire, extinct from the 17th century. It may be derived from malinke, an indigenous people of this region or from a mandingo word meaning hippopotamus. (12 Dec 1998) |
| malic | <chemistry> Pertaining to, or obtained from, apples; as, malic acid. Malic acid, a hydroxy acid obtained as a substance which is sirupy or crystallized with difficulty, and has a strong but pleasant sour taste. It occurs in many fruits, as in green apples, currants, etc. It is levorotatory or dextrorotatory according to the temperature and concentration. An artificial variety is a derivative of succinic acid, but has no action on polarized light, and thus malic acid is a remarkable case of physical isomerism. Origin: L. Malum an apple: cf. F. Malique. Source: Websters Dictionary (01 Mar 1998) |
| malic acid | HOOC-CH2-CHOH-COOH; hydroxysuccinic acid;an acid found in apples and various other tart fruits; an intermediate in the tricarboxylic acid cycle, the glyoxylate cycle, and in a shuttle system. Synonym: monohydroxysuccinic acid. (05 Mar 2000) |
