| fracture fixation | The use of metallic devices inserted into or through bone to hold a fracture in a set position and alignment while it heals. (12 Dec 1998) |
|---|---|
| fracture fixation, internal | The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment. (12 Dec 1998) |
| intramedullary | 1. Within the bone marrow. 2. Within the spinal cord. 3. Within the medulla oblongata. (05 Mar 2000) |
| intramedullary anaesthesia | Rarely used method of general anaesthesia by injection of intravenous anaesthetic agent(s) into the medullary canal of long bones. Synonym: intraosseous anaesthesia. (05 Mar 2000) |
| intramedullary mass | <radiology> Ependymoma, astrocytoma, syrinx, post-radiation myelopathy, haematoma (posttraumatic or AVM) (12 Dec 1998) |
| intramedullary reamer | A rasp used for shaping the intramedullary portion of the metaphysis prior to the insertion of an appliance or a prosthesis. (05 Mar 2000) |
| intramedullary tractotomy | Division of the descending fibres of the trigeminal tract in the medulla. Synonym: intramedullary tractotomy, Sjoqvist tractotomy. (05 Mar 2000) |
| ammonia fixation | The utilization of ammonia (or ammonium ions) in the net synthesis of nitrogen-containing molecules; e.g., glutamine synthetase. Synonym: ammonia fixation. (05 Mar 2000) |
| bifoveal fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| binocular fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| carbon fixation | <plant biology> The process by which photosynthetic organisms such as plants turn inorganic carbon (usually carbon dioxide) into organic compounds (us. Carbohydrates). (09 Oct 1997) |
| mandibulomaxillary fixation | Fixation of fractures of the mandible or maxilla by applying elastic bands or stainless steel wire between the maxillary and mandibular arch bars or other types of splint. Synonym: mandibulomaxillary fixation, maxillomandibular fixation. (05 Mar 2000) |
| genes, nitrogen fixation | Regulatory and structural genes present in certain bacteria, algae and fungi that control the conversion of atmospheric nitrogen into biologically usable compounds; include nif structural genes (e.g., nifd, nifh) for nitrogenase and nitrate reductase as well as regulator genes nifa, nifb, ntra, ntrb, ntrc. Some are responsible for regulating transcription of genes involved in the assimilation of poor nitrogen sources in enteric bacteria. (12 Dec 1998) |
| genetic fixation | The increase of the frequency of a gene by genetic drift until no other allele is preserved in a specific finite population. (05 Mar 2000) |
