SR3 Intro To Trauma Flashcards
A burst fracture of the atlas is known as
Jefferson fracture
A normal variant in children aged 4-10 in which the atlas lateral masses may be lateral to the superior articulating surface of C2 is called ____. This can be confused with a Jefferson fx
Pseudospread (Pseudo-Jefferson fx)
On the checklist for spinal instability, _ points or more = unstable
5
In the checklist for spinal stability, A/P translation >__mm, and flexion/extension >__degrees between levels = 2 points each
3.5mm, 11 degrees
In relation to the three “columns” of the spine, injuries involving __ or more columns are likely unstable and will likely result in neurologic injury
Two
What type of fracture? Cortex is broken on only one side of the bone
Incomplete fx
Two types of incomplete fx: ____ = bowing of the bone, and ___ = buckling of the cortex
Greenstick, torus
A fracture that is not covered by intact skin
Open fracture
A fracture that has more than two fracture fragments
Comminuted fx
A comminuted fracture of a vertebral body produced by an axial load on a neutral spine. Fracture fragments displace anteriorly and posteriorly. Unstable with injury to spinal cord
Burst fracture
The fragment is pulled away from the parent bone by ligamentous or tendinous action
Avulsion fx
A fracture produced by abnormal stress on normal bone
Fatigue fx
A fracture produced by normal stress on abnormal bone. Ex: Sacrum
Insufficiency fx
Heterotopic bone formation due to soft tissue injury. Calcification of hematoma occurs within four weeks. Bone matures, then resorbs. (Old blood turns into bone)
Myositis ossificans
_____ syndrome has an unknown etiology, altered function of sympathetic nervous system, intense pain/swelling. Radiographs show patchy osteoporosis. Self limiting, but not always complete recovery
Reflex Sympathetic Dystrophy Syndrome (RSDS)
