| 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) |
| bending fracture | <orthopaedics, radiology> An injury in which a long bone or bones, usually the radius and ulna, are bent due to multiple microfractures, none of which can be seen by X-ray imaging. (14 Aug 2000) |
| bennett fracture | <radiology> Mechanism: forced abduction of thumb, findings: intraarticular fracture/dislocation of the base of the 1st metacarpal at the ulnar aspect, small fragment of metacarpal continues to articulate with the trapezium, lateral retraction of metacarpal shaft by abductor pollicis longus, difficult to keep in anatomical alignment, complication: pseudoarthrosis, better prognosis than Rolando fracture see: thumb fractures (12 Dec 1998) |
| Bennett's fracture | <orthopaedics> A fracture-dislocation of the first metacarpal bone (thumb) at the carpal metacarpal joint. (06 Aug 1998) |
| birth fracture | Fracture occurring during the trauma of delivery or, occasionally, before delivery in infants with osteogenesis imperfecta. (05 Mar 2000) |
| blow-out fracture | A fracture of the floor of the orbit, without a fracture of the rim, produced by a blow on the globe with the force being transmitted via the globe to the orbital floor. (05 Mar 2000) |
| boxer's fracture | Fracture of the neck of a metacarpal bone-typically of the fifth metacarpals. (05 Mar 2000) |
| capillary fracture | A fracture without separation of the fragments, the line of break being hairlike, as seen sometimes in the skull. Synonym: capillary fracture. (05 Mar 2000) |
| galeazzi fracture | <radiology> Fracture of the radius at the junction of the middle and distal thirds, with associated subluxation of the distal ulna see: forearm fractures (12 Dec 1998) |
| Galeazzi's fracture | <orthopaedics> A fracture of the forearm characterised by fracture of the shaft of the radius with dislocation of the distal radio-ulnar joint. (27 Sep 1997) |
| maisonneuve fracture | <radiology> Components: fracture of the proximal third of the fibula, rupture of the distal tibiofibular syndesmosis associated with: fracture of the tibia, rupture of the deltoid ligament caused by an abduction and external rotation force applied to the ankle which forces the talus laterally against the fibula (12 Dec 1998) |
| malgaigne fracture | <radiology> Two vertical fractures involving one side of the pelvic ring, one fracture anterior to the acetabulum, usually through the pubic ramus, one fracture posterior to the acetabulum, usually through the ilium, separation of the SI joint may occur instead usually the result of direct trauma (12 Dec 1998) |
