| compression syndrome | Trauma and ischemia of soft tissues, principally skeletal muscle, due to prolonged severe crushing of the tissues, leading to increased permeability of the cell membrane and to the release of potassium, enzymes, and myoglobin from within cells. Ischemic renal dysfunction secondary to hypotension and diminished renal perfusion results in acute tubular necrosis and uraemia. (12 Dec 1998) |

| compression thrombosis | Thrombosis due to arrest of the circulation in a vessel by compression, as from a tumour. (05 Mar 2000) |
| compression wave | <radiobiology> Waves where the quantity which oscillates is the density of the medium, that is the medium at a given point alternately compresses and expands. Low-amplitude compression waves in air or water are commonly known as sound waves, shock waves are a high-amplitude form. Synonym: density wave. (13 Jan 1998) |
| heat of compression | Heat produced when a gas is compressed. (05 Mar 2000) |
| spinal cord compression | A condition in which pressure is exerted on the spinal cord, as by a tumour, spinal fracture, etc. Its manifestations, which vary with location and degree of pressure, may include pain, paresthesias, and sensory and motor disturbances. (12 Dec 1998) |
| nerve compression syndromes | Repeated or prolonged pressure on a nerve root or peripheral nerve leading to ischemia, the response to which is oedema above and below the source of pressure. If the pressure is not relieved, fibrosis tends to develop. Types of nerve compression syndromes are the neuropathy caused by intervertebral disk herniation, compression of the median nerve in the carpal tunnel, compression of the ulnar nerve in the elbow, and compression of the lateral cutaneous nerve of the thigh in meralgia paresthetica. This is also called pressure neuropathy. (12 Dec 1998) |
| eyeball compression reflex | Slowing of the heart rate due to the vagal effects of compressing an eyeball. Synonym: eyeball compression reflex. (05 Mar 2000) |
| ulnar nerve compression syndrome | <syndrome> A condition caused by compression or entrapment of the ulnar nerve. It may involve both sensory and motor problems and most often results from compression or entrapment of the ulnar nerve at the elbow (cubital tunnel syndrome). Compression of the nerve may occur during normal activities or as a complication of general anaesthesia. (12 Dec 1998) |
| mandibular fractures | Fractures of the lower jaw. (12 Dec 1998) |
| maxillary fractures | Fractures of the upper jaw. (12 Dec 1998) |
| cervical spine fractures | <radiology> Hyperflexion injury (46-79%), odontoid fracture, simple wedge fracture (stable), tear drop fracture, anterior subluxation, bilateral locked facets (unstable), anterior disc space narrowing, widened interspinous distance, clay shoveler's fracture hyperextension injury (20-38%), anteriorly widened disc space, prevertebral swelling, tear drop fracture, neural arch fracture of C1, subluxation (anterior/posterior), hangman's fracture flexion-rotation injury (12%), unilateral locked facets (stable) vertical compression (12%), Jefferson fracture, burst fracture lateral flexion/shearing (4-6%), uncinate fracture, isolated pillar fracture, transverse process fracture, lateral vertebral compression location (by frequency): C2,C6 greater than C5,C7 greater than C3,C4 greater than C1 see: atlas fracture, axis fracture, unstable fractures (12 Dec 1998) |
| closed reduction of fractures | Reduction by manipulation of bone, without incision in the skin. (05 Mar 2000) |
| wrist fractures | <radiology> Colles fracture distal radius DORSAL angulation of distal fragment, Smith fracture distal radius (reverse Colles) volar angulation of distal fragment, Barton intra-articular fracture through DORSAL aspect of radius ventral Barton: through VENTRAL aspect, chauffeur's fracture of radial styloid (intra-articular) (12 Dec 1998) |
| salter-harris fractures | <radiology> Classification of epiphyseal fractures, I pure epiphyseal separation if non-displaced, joint effusion may be only sign, II metaphyseal fracture and epiphyseal separation, III epiphyseal fracture, IV vertically oriented fracture through epiphysis and metaphysis, V crush injury of epiphysis (not detected acutely), most common: type II, type I (best) may lead to type V (worst), seen in kiddies before the physes close (12 Dec 1998) |
| hip fractures | Fractures of the femur head, the femur neck, the trochanters, or the inter- or subtrochanteric region. Excludes fractures of the acetabulum and fractures of the femoral shaft below the subtrochanteric region. For the fractures of the femur neck the specific term femoral neck fractures is available.
