| 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, 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) |
| biopsy, open lung | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of lung tissue for microscopic analysis via a surgical incision in the chest wall. This test can be used to identify a variety of lung cancers, lung infections and lung diseases. (21 Mar 1998) |
| reading frame, open | An open reading frame in DNA has no termination codon, no signal to stop reading the nucleotide sequence, and so may be translated into protein. (12 Dec 1998) |
| glaucoma, open-angle | Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris. (12 Dec 1998) |
