trauma Flashcards
how does the ARRT define trauma?
a serious injury or shock to the body, often requiring modifications that may include variations in positioning, minimal movement of the body part, and so on…
types of trauma
blunt
penetrating
explosive
thermal forces
It is (good/poor) practice to accept lower quality images because of patient condition or difficulty of procedure
poor
displacement of a bone that is no longer in contact with its normal articulation
dislocation
occurs when a bone is partially pulled or pushed out of place in relation to its normal alignment
sublaxation
a wrenching or twisting of a joint resulting in a tearing or rupturing of associated soft tissues without dislocation
sprain
a bruise type of injury. Can sometimes be associated with a bony injury
contusion
a disruption of bone caused by a force applied either directly to the bone, or transmitted along the shaft of the bone
fracture
how the fragmented ends of the bone make contact with each other. There are three terms to describe this relationship; what are they?
apposition
anatomic, lock of apposition (distraction), bayonet apposition
type of apposition where the fractured ends of the bone align anatomically making contact with each other
anatomic apposition
type of apposition where the ends of the fragmented bone are aligned, but pulled apart with a gap between them
lack of apposition (distraction)
type of apposition where the bone fragments are displaced and overlapping each other so that the shafts of the bone are in contact with each other
bayonet apposition
__________ describes the loss of alignment of the fracture and the direction of angulation caused by this misalignment. there are three types; what are they?
angulation
apex angulation, varus deformity, valgus deformity
The apex of the angulation is __________ in relation to the distal ends of the fractured bone
opposite
angulation which describes the angle or direction of the fragment such as a medial or lateral apex in which the point of the angle points medially or laterally
apex angulation
angulation which describes when apex is pointing away from the midline of the body and the distal ends of the fractured bone are angled towards the midline of the body
varus deformity
angulation which describes when apex is pointing to the midline of the body and the distal ends of the fractured bone are angled away from the midline
valgus deformity
fracture in which the bone does not break through the skin
simple fracture (closed)
a fracture in which a portion of the bone breaks through the skin. This is typically the fragmented end
compound fracture
fracture does not completely transverse the bone. More common in __________ patients who still have more _____________
incomplete fracture (partial); pediatric, flexible bone tissue
two types of incomplete/partial fracture
torus “buckle,” greenstick
a buckle of the outer portion of the bone (the cortex) with localized expansion of the cortex with little to no displacement or complete break in the cortex
torus or “buckle” fracture
this fracture is on one side of the bone only with the cortex of the affected side of the bone broken and the cortex on the other side bent
greenstick fracture
the bone is broken into two separate pieces. There is a complete fracture that includes the cross section of the bone
complete fracture
three types of complete fractures
transverse, oblique, spiral
the fracture is nearly at a right angle to the long axis of the bone
transverse fracture
the fracture crosses the long axis of the bone at an oblique angle
oblique fracture
the bone has been twisted and the fracture spirals around the long axis of the bone
spiral fracture
the bone is splintered and/or crushed at the site of the fracture resulting in two or more pieces
comminuted fracture
three types of comminuted fracture
segmental, butterfly, splintered
