| interosseous border of tibia | The ridge along the lateral border of the tibia to which is attached the interosseous membrane. Synonym: margo interosseus tibiae. (05 Mar 2000) |

| tibia | <anatomy> The large bone between the knee and foot that supports 5/6 of the body weight (fibula supports 1/6). (27 Sep 1997) |
| tibia valga | A deformity marked by lateral angulation of the leg in relation to the thigh. Synonym: knock-knee, tibia valga. (05 Mar 2000) |
| tibia vara | <radiology> (Blount disease) Common, causes bowlegs in kids, possibly due to ischemic necrosis, associated with early walking Findings: bilateral tibia vara (bowleggedness), abnormal medial aspect of proximal tibia, small epiphysis, beaked metaphysis (12 Dec 1998) |
| fibular articular surface of tibia | The flat circular articular facet on the inferior and lateral aspect of the lateral condyle of the tibia for articulation with the head of the fibula. Synonym: facies articularis fibularis tibiae. (05 Mar 2000) |
| lateral condyle of tibia | The lateral condyle is longer than the medial condyle. Synonym: condylus lateralis tibiae. (05 Mar 2000) |
| lateral surface of tibia | The laterally directed surface of the tibia. Synonym: facies lateralis tibiae. (05 Mar 2000) |
| apophysial fracture | Separation of apophysis from bone. (05 Mar 2000) |
| articular fracture | A fracture involving the joint surface of a bone. (05 Mar 2000) |
| atlas fracture | <radiology> Incidence: 4% of cervical spine injuries, site: posterior arch, anterior arch, massa lateralis, Jefferson fracture associated with: fractures of C7 (25%), fractures of C2 pedicle (15%), extraspinal fractures (58%) (12 Dec 1998) |
| avulsion fracture | A fracture that occurs when a joint capsule, ligament, or muscle insertion of origin is pulled from the bone as a result of a sprain dislocation or strong contracture of the muscle against resistance; as the soft tissue is pulled away from the bone, a fragment or fragments of the bone may come away with it. (05 Mar 2000) |
| axis fracture | <radiology> Incidence: 6% of cervical spine injuries, associated with atlas fractures in 8%, hyperflexion injury: odontoid fracture, type I avulsion of tip of odontoid (5-8%) difficult to detect, type II fracture through base of dens (54-67%) complication: nonunion, type III subdental injury (30-33%) prognosis: good, Differential diagnosis: os odontoideum, ossiculum terminale, hypoplasia/aplasia of dens, hyperextension injury: hangman's fracture (12 Dec 1998) |
| barton fracture | <radiology> Intra-articular fracture of distal radius, dorsal displacement of separated fragment, due to fall on outstretched hand see: wrist fractures (12 Dec 1998) |
| Barton's fracture | Fracture of the distal radius with dislocation of the radiocarpal joint. (05 Mar 2000) |
| basal skull fracture | <orthopaedics> A fracture involving the base of the cranium. This fracture is often difficult to detect clinically. Findings may include raccoon eyes, Battle's sign, haemotympanum and cerebrospinal fluid rhinorrhoea. Plain skull X-ray will often not reveal the basal skull fracture, making a CT scan or MRI the most reliable diagnostic investigation. (15 Nov 1997) |
