Flashcards in BS Deck (41):
1

Antalgic gait

shortened stance phase due to pain

2

Radiculopathy

Disease of nerve root

3

Gibbus deformity

pronounced, adulated thoraco-lumbar kyphosis

4

Subluxation

Displacement of articular joint surfaces with some contact- partial dislocation

5

Arthrodesis

Surgical fixation of joint, bone fusion

6

Athroplasty

Surgical reconstruction or replacement of malformed or degenerated joint

7

No mans land of hand

Fibrous sheet of flexor tendons of hand

8

Translation

Sliding of fracture fragments- % and direction of slide

9

Shortening

Length of bone shorter as result of fracture fragments sliding past eachother

10

Rotation

Fracture along axis of long bone- described in degrees from distal fragment

11

Angulation

Angular deformity of fracture. Displacement from normal axis of distal fragment

12

Alignment/ displacement

Misalignment of bone- goal to realign

13

Malunion

Fracture ends do not heal together

14

Apposition

Amount of end to end contact of fracture- described in percent

15

Stress fx

Small fracture due to repetitive use. Typically weight bearing bones

16

Pathologic

Break due to abnormal condition weakening bone

17

Compression

Weak bone crumples under force of gravity- common in spine, osteoporosis

18

Comminuted

Multiple fragments

19

Transverse

Line perpendicular to axis of long bone- 2 fragments

20

Oblique

Fracture line diagonal to axis of long bone

21

Greenstick

Incomplete breakage of bone in children- soft flexible bone

22

Torus/ buckle

Cortex of bone collapses, commonly due to trauma

23

Spiral

Fracture plane like corkscrew- due to twist or rotational force

24

Remodeling

Resorption and replacement of bone

25

Callus

Connecting bridge of bony material during fracture repair- 2 weeks after injury

26

Radiography

Ionizing radiation passed through area of interest. Denser material whiter. Good for bones

27

Radiodensity

Materials with higher atomic numbers appear whiter on film

28

Radiolucent

lower atomic numbers, more permeable to x-rays, darker

29

Black on x-ray

gas & air

30

Grey-black on x-ray

Fat plates

31

Grey-white

fluid, soft tissues, muscles, tendons

32

White

Bone, metal, contrast material

33

CT

Rapid evaluation of critical patient, increase in density discrimination. Uses x-rays

34

Nuclear medicine

Evaluates physiologic function using gamma camera.

35

Bone scan

Indicates area of rapid cell growth- bone METs

36

PET scan

Dx & monitoring of Cx- areas of high metabolic activity

37

US

Using sound waves. Quick, noninvasive, very dependent on skill of technologist- Gallstones, arteries

38

MRI

Strong magnetic field. No radiation- Cant use with metallic foreign bodies. Takes hours. Great soft tissue contrast- ligamentous and soft tissue injuries, brain and spine

39

Fluoroscopy

Continuous x-ray image- catheter insertion, placement of devices

40

Contrast studies

Injection of contrast medium to determine functional A&P- urinary & GI system

41

Risks of radiation exposure

Impairment of tissue function- skin redness, hair loss, burns. Increased risk of cancer. DNA damage, release of free radicals.
