| embolism, fat | Embolism caused by fat entering the circulation. It is often seen after fractures of large bones or after corticosteriod administration. (12 Dec 1998) |
| embolism, paradoxical | Passage of a clot (thrombus) from a vein to an artery. When clots in veins break off (embolise) , they travel first to the right side of the heart and, normally, then to the lungs where they lodge. The lungs act as a filter to prevent the clots from entering the arterial circulation. However, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism. Once in the arterial circulation, a clot can travel to the brain, block a vessel there, and cause a stroke (cerebrovascular accident). Because of the risk of stroke from paradoxical embolism, it is usually recommended that even small atrial septal defects be repaired. Also called crossed embolism. (12 Dec 1998) |
| tumour embolism | Embolism by neoplastic tissue transported from a tumour site and which may grow as a metastasis. (05 Mar 2000) |
| fat embolism | <orthopaedics> The occurrence of fat globules in the bloodstream following fracture of a long bone, in burns, in childbirth or in association with fatty degeneration of the liver. Symptoms occur when fat globules block vessels within the lung (i.e. Pulmonary embolism) or the cerebral vasculature (i.e. Stroke). Fat embolism after bone fracture generally occurs in the first 3-4 days post fracture and commonly manifests with the signs and symptoms of pulmonary embolism. (27 Sep 1997) |
| lymph embolism | Lymphogenous embolism, embolism occurring in a lymphatic vessel. (05 Mar 2000) |
| acute reflex bone atrophy | Atrophy of bones, commonly of the carpal or tarsal bones, following a slight injury such as a sprain. See: causalgia, reflex sympathetic dystrophy. Synonym: acute reflex bone atrophy, posttraumatic osteoporosis, Sudeck's syndrome. Origin: L. English sweat (05 Mar 2000) |

| Albrecht's bone | A small bone between the basioccipital and basisphenoid. (05 Mar 2000) |
| alveolar bone | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar bone loss | The resorption of bone in the supporting structures of the maxilla or mandible as a result of periodontal disease. (12 Dec 1998) |
| alveolar supporting bone | alveolar process |
| amyloidosis: bone manifestations | <radiology> Joint pain without radiographic findings, osteoporosis, especially in axial skeleton, lytic lesions that destroy cortex and invade soft tissue, wrist, scaphoid and lunate lesions that may extend into the carpal tunnel, inducing the classic complaints of carpal tunnel syndrome amyloid arthropathy Differential diagnosis: pigmented villonodular synovitis, synovial chondromatosis, rheumatoid arthritis, TB (12 Dec 1998) |
| aneurysmal bone cyst | <radiology> ABC, 10 - 30 yrs, 75% before skeletal maturity, sites: long bones; also, flat bones Findings: metaphyseal if unfused, metaepiphyseal after fusion, lytic, expansile, thin, continuous rim, thin internal bony strands (12 Dec 1998) |
| ankle bone | 1. <anatomy> The astragalus. 2. <surgery> A variety of clubfoot (Talipes calcaneus). See the Note under Talipes. 1. A slope; the inclination of the face of a work. 2. <geology> A sloping heap of fragments of rock lying at the foot of a precipice. Origin: L, the ankle, the ankle bone. (26 Nov 1998) |
