| bone graft | Bone transplanted from a donor site to a recipient site. See: osteoplasty. (05 Mar 2000) |
|---|---|
| bone infarct | An area of bone tissue that has become necrotic as a result of loss of its arterial blood supply. (05 Mar 2000) |
| bone island | <radiology> Small, intramedullary island of compact bone, usually negative on bone scan, shaggy, slightly stellate border, Differential diagnosis: osteoid osteoma, multiple leading to osteopoikilosis (12 Dec 1998) |
| bone lengthening | Increase in the longest dimension of a bone to correct anatomical deficiencies, congenital, traumatic, or as a result of disease. The lengthening is not restricted to long bones. The usual surgical methods are internal fixation and distraction. (12 Dec 1998) |
| bone malalignment | Displacement of bones out of line in relation to joints. It may be congenital or traumatic in origin. (12 Dec 1998) |
| bone matrix | The intercellular substance of bone tissue consisting of collagen fibres, ground substance, and inorganic bone salts. (05 Mar 2000) |

| bone metastases in kids | <radiology> Rhabdomyosarcoma, neuroblastoma, histiocytosis X Note: Wilms tumour goes to lung, not bone (12 Dec 1998) |
| bone morphogenetic protein | <protein> Activity derived from bone that induces the formation of cartilage and bone in vivo. Seven bone morphogenetic proteins have been described, BMP 1 being the only one not in the TGF beta superfamily. BMP 3 was formerly called osteogenin. Acronym: BMP (18 Nov 1997) |
| bone morphogenetic proteins | Non-collagenous factors, believed to be proteins, that occur in demineralised bone and stimulate osteogenesis. They can induce new bone formation in ectopic sites and thus have potential use in bone repair. (12 Dec 1998) |
| bone nails | Rods of bone, metal, or other material used for fixation of the fragments or ends of fractured bones. (12 Dec 1998) |
| bone phosphate | Ca3(PO4)2;used as an antacid. Synonym: bone ash, bone phosphate, tertiary calcium phosphate, tricalcium phosphate, whitlockite. (05 Mar 2000) |
| bone plate | A metal bar with perforations for the insertion of screws; used to immobilise fractured segments. (05 Mar 2000) |
| bone plates | Metal bars with perforations for the insertion of screws, used to immobilise fractured segments. (12 Dec 1998) |
| bone reflex | A reflex excited by a stimulus applied to a bone. (05 Mar 2000) |
