| Gibney's fixation bandage | A herring-bone strapping of the foot and leg for sprain of the ankle. (05 Mar 2000) |
|---|---|
| maxillomandibular 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) |
| Roger-Anderson pin fixation appliance | An appliance used in extraoral fixation of mandibular fractures and prognathic corrections in which pins placed in the bone segments are joined by metal connecting rods. See: external pin fixation. (05 Mar 2000) |
| circumalveolar fixation | Stabilization of a fracture segment or surgical splint by wire passed through and around the dental alveolar process. (05 Mar 2000) |
| circummandibular fixation | Stabilization of a fracture segment or surgical splint by wire passed around the mandible. (05 Mar 2000) |
| circumzygomatic fixation | Stabilization of a fracture segment or surgical splint by wire passed around the zygomatic arch. (05 Mar 2000) |
| point of fixation | The point on the retina at which the rays coming from an object regarded directly are focused. Synonym: point of regard. (05 Mar 2000) |
| craniofacial fixation | Stabilization of facial fractures to the cranial base by direct wiring or by external skeletal pin fixation. (05 Mar 2000) |
| crossed fixation | In convergent strabismus, the use of the right inturned eye to look at objects to the left and the left inturned eye to look at objects to the right, in order to avoid ocular rotation. (05 Mar 2000) |
| crossover fixation | <molecular biology> The addition of extra copies of segments of DNA on the same strand by unequal crossing over during meiosis. An explanation for the existence of satellite DNA, which are highly-repeated, non-transcribed sequences of DNA with no clear function. An alternative explanation to saltatory replication. (03 Jul 1999) |
| nasomandibular fixation | Mandibular immobilization, especially for edentulous jaws, with maxillomandibular splints, attached by connecting a circum-mandibular wire with an intraoral interosseous wire passed through a hole drilled into the anterior nasal spine of the maxillae. (05 Mar 2000) |
| nitrogen fixation | <biochemistry> The incorporation of atmospheric nitrogen into ammonia by various bacteria, catalysed by nitrogenase. This is an essential stage in the nitrogen cycle and is the ultimate source of all nitrogen in living organisms. In the sea, the main nitrogen fixers are Cyanobacteria. There are several free living bacteria in soil that fix nitrogen including species of Azotobacter, Clostridium and Klebsiella. Rhizobium only fixes nitrogen when in symbiotic association, in root nodules, with leguminous plants. The oxygen sensitive nitrogenase is protected by plant produced leghaemoglobin and the plant obtains fixed nitrogen from the bacteria. See: Frankia. (18 Nov 1997) |
| intermaxillary 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) |
| internal fixation | The use of internal metal plates, screws or rods to stabilise bone fragments. A procedure used to correct serious orthopaedic bone fractures that cannot be stabilised by casting or splinting. See: external fixation. (27 Sep 1997) |
| intraosseous fixation | The use of internal metal plates, screws or rods to stabilise bone fragments. A procedure used to correct serious orthopaedic bone fractures that cannot be stabilised by casting or splinting. See: external fixation. (27 Sep 1997) |
