| bone density | Bone density is the amount of bone tissue in a certain volume of bone. It can be measured using a special X-ray called a quantitative computed tomogram. (12 Dec 1998) |
|---|---|
| bone development | Gross development of bones from foetus to adult. It includes osteogenesis, which is restricted to formation and development of bone from the undifferentiated cells of the germ layers of the embryo. It does not include osseointegration. (12 Dec 1998) |
| bone diseases, endocrine | Diseases of the bones related to hyperfunction or hypofunction of the endocrine glands. (12 Dec 1998) |
| bone diseases, infectious | Bone diseases caused by pathogenic microorganisms. (12 Dec 1998) |
| bone dry | Having zero percent moisture content. Wood heated in an oven at a constant temperature of 212 degrees F or above until its weight stabilises is considered bone dry or oven dry. (05 Dec 1998) |
| bone dry unit | A quantity of wood residue which weighs 2,400 pounds at zero percent moisture content. (05 Dec 1998) |
| bone flap | Portion of cranium removed but left attached to overlying soft tissue structures. (05 Mar 2000) |
| bone forceps | A strong forceps used for seizing or removing fragments of bone. (05 Mar 2000) |
| bone: gallium imaging | <radiology> Increased activity in: active osteomyelitis (90% sensitivity: better than Tc-99m MDP), sarcoma, cellulitis, septic arthritis, rheumatoid arthritis, Paget disease, metastases (65% sensitivity: than for bone agents) see: gallium: indications (12 Dec 1998) |
| bone Gla protein | <protein> Polypeptide of 50 residues formed from a 76-77 amino acid precursor and found in the extracellular matrix of bone. Binds hydroxyapatite. Has limited homology of its leader sequence with that of other Vitamin K dependent proteins such as prothrombin, Factors IX and X and Protein C. (18 Nov 1997) |
| bone graft | Bone transplanted from a donor site to a recipient site. See: osteoplasty. (05 Mar 2000) |

| 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) |
