| unstable cervical spine fractures | <radiology> Flexion: bilateral interfacetal dislocation, flexion teardrop fracture (usually C5 or C6) extension: extension teardrop fracture (usually C2 or C3), hangman's fracture, extension-dislocation, extension-fracture-dislocation, odontoid fracture vertical compression: Jefferson burst fracture see: cervical spine fractures (12 Dec 1998) |
|---|---|
| femoral fractures | Fractures of the femur. (12 Dec 1998) |
| femoral neck fractures | Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters. It excludes intertrochanteric fractures which are hip fractures. (12 Dec 1998) |
| zygomatic fractures | Fractures of the zygoma. (12 Dec 1998) |
| forearm fractures | <radiology> Monteggia proximal ulnar fracture dislocated radial head, Galeazzi radial fracture dislocated distal ulna, mnemonic: MUGR (Monteggia ulna, Galeazzi radius), Monteggia More common (12 Dec 1998) |
| fractures | Breaks in bones or cartilage. (12 Dec 1998) |
| fractures, closed | Fractures in which the break in bone is not accompanied by an external wound. (12 Dec 1998) |
| fractures, comminuted | A fracture in which the bone is splintered or crushed. (12 Dec 1998) |
| fractures, malunited | Union of the fragments of a fractured bone in a faulty or abnormal position. If two bones parallel to one another unite by osseous tissue, the result is a crossunion. (12 Dec 1998) |
| fractures, open | Fractures in which there is an external wound communicating with the break of the bone. (12 Dec 1998) |
| fractures, spontaneous | Fractures occurring as a result of disease of a bone or from some undiscoverable cause, and not due to trauma. (12 Dec 1998) |
| fractures, stress | Fractures due to the strain caused by repetitive exercise. They are thought to arise from a combination of muscle fatigue and bone failure, and occur in situations where bone remodeling predominates over repair. The classical stress fracture is the march fracture of military personnel, in which the metatarsal undergoes repeated stress during marching. The most common sites of stress fractures are the metatarsus, fibula, tibia, and femoral neck. (12 Dec 1998) |
| fractures, ununited | A fracture in which union fails to occur, the ends of the bone becoming rounded and eburnated, and a false joint occurs. (12 Dec 1998) |
| acute lower GI haemorrhage | <gastroenterology> Typical presentation: Sudden onset of brisk rectal bleeding without blood in gastric aspirate Diagnostic considerations: diverticulosis, angiodysplasia, ischemic colitis, inflammatory bowel disease (rarely), polyps are usually present, carcinoma causing a chronic bleed, haemorrhoids. (12 Dec 1998) |
| arterial arch of lower eyelid | Formed by the medial palpebral artery which communicates with a branch of the lacrimal artery along the tarsal margin. Synonym: arcus palpebralis inferior. (05 Mar 2000) |
