| compact bone | The compact, noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae. Synonym: substantia compacta, compact substance, substantia compacta ossium. (05 Mar 2000) |

| compact disks | Computer disks storing data with a maximum reduction of space and bandwidth. The compact size reduces cost of transmission and storage. (12 Dec 1998) |
| compact substance | The compact, noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae. Synonym: substantia compacta, compact substance, substantia compacta ossium. (05 Mar 2000) |
| compact torus | <radiobiology> Any of a series of axially symmetric fusion configurations having closed flux surfaces (like a tokamak, not like a mirror machine), but having no material objects piercing the core (as do the toroidal field coils of a tokamak). These devices have an inherently low aspect ratio, approximately unity. The most successful variants are the spheromak and the Field Reversed Configuration. See: low aspect ratio, spheromak, field-reversed configuration. (05 Jan 1998) |
| giant osteoid osteoma | A benign, painful, tumour of bone characterised by the formation of osteoid tissue, primitive bone and calcified tissue. It occurs frequently in the spine of young persons. (12 Dec 1998) |
| osteoid osteoma | <radiology> M more than F, 15 - 30 years of age, lucent nidus with thickened cortex, metaphyseal, femur, talus, tibia, patella, rarely spine, never skull or clavicle, pain at night, relievey be inflammatory rather than neoplastic, treatment: leave it (disappears in 4-6 yrs), or remove nidus, Differential diagnosis: TB abscess, chronic osteo (Brodie abscess), sclerosing osteomyelitis of Garre (12 Dec 1998) |
| osteoma | <oncology, tumour> Benign tumour of bone. (18 Nov 1997) |
| osteoma medullare | An osteoma containing spaces that are filled (or partly filled) with various elements of bone marrow. Osteoid osteoma, a painful benign neoplasm that usually originates in one of the bones of the lower extremities, especially the femur or tibia of adolescent and young adult persons; characterised by a nidus (usually no larger than 1 cm in diameter) that consists of osteoid material, vascularised osteogenic stroma, and poorly formed bone; around the nidus there is a relatively large zone of reactive thickening of the cortex. Osteoma spongiosum, an osteoma that consists chiefly of cancellous bone tissue. (05 Mar 2000) |
| osteoma, osteoid | Benign circumscribed tumour of spongy bone occurring especially in the bones of the extremities and vertebrae, most often in young persons. (12 Dec 1998) |
| fibro-osteoma | <tumour> An osteoma in which the neoplastic bone-forming cells are situated within a relatively abundant stroma of fibrous tissue. (05 Mar 2000) |
| compact osteoma |
a small, dense, compact tumor of mature lamellar bone with little medullary space, usually occurring in the craniofacial or nasal bones.
