Interbody bone fusion device
titanium or other alloy cage filled with bone and inserted between the vertebral bodies to maintain disk space height and permit fusion of the intervertebral joint
26
Intramedullary rod
a flexible or rigid device placed within the medullary cavity to reduce a fracture or stabilize a diseased long bone
27
Kirschner wire K-wire
unthreaded (smooth) or threaded metallic wire used to reduce fractures of the wrist (carpals) and individual bones of the hands and feet; also may be used for skeletal traction
28
Laminectomy
surgical procedure performed to alleviate pain caused by neural impingement by removing an aspect of the lamina in the vertebral arch Laminectomy can be performed on cervical in an anterior approach (pt is supine) or lumbar regions in a posterior approach (pt is prone).
29
Laminotomy
surgical opening into one or more laminae of the vertebral arch
30
Laparoscopic cholecystectomy
use of a special endoscopic device to visualize and assist with surgical removal of the gallbladder
31
Lithotripsy
crushing of calcification in the renal pelvis, ureter, or urinary bladder by mechanical force or sound waves
32
Microdiskectomy
microsurgical procedure performed on the spine to remove bony fragments or disk material that may be causing neural impingement
33
Neural impingement
condition in which bony changes or a herniated disk produces impingement of the spinal nerves that pass through the vertebral arch of the vertebrae
34
Open reduction
reduction of fracture fragments through surgical intervention
35
Operative (immediate) cholangiography
Radiographic procedure performed during surgery to visualize and locate undetected stones or obstructions within the biliary ducts
36
ORIF
Open reduction with internal fixation
37
PCL
Posterior cruciate ligament
38
Prosthesis
Fabricated (artificial) substitute for a diseased or missing anatomic part
39
Reduce
To align two bone fragments in the correct position as treatment for a fracture, as applied in orthopedic medicine
40
Retrograde urography
a nonfunctional examination of the urinary system during which contrast media is introduced directly retrograde (backward, against the flow) into the pelvicalyceal system via catherization by a urologist during a minor surgical procedure. At least 3 images are obtained. First a scout film. Second is a pyelogram. Third radiograph is a ureterogram.
41
Semitubular plate
flexible and thin orthopedic plate used to fix and connect fractures
42
Shower Curtain
an isolation drape that seperates the sterile field from the nonsterile environment; often used to permit the use of C arm fluoroscopy during a hip pinning procedure
43
Spinal fusion
surgical fusion of one vertebra to another, which stabilizes them following laminectomy or as treatment for a degenerative condition or fracture
44
Spinal Stenosis
condition caused by degenerative changes that result in enlargement of the facet joints, which often leads to impingement of the spinal nerves that pass by them.
45
Strike-through
soaking of moisture through a sterile or nonsterile drape, cover, or protective barrier, permitting bacteria to reach sterile areas
46
THR, THA
Total hip replacement, total hip appliance
47
TKR, TKA
Total knee replacement, total knee appliance
48
Total Joint Arthroplasty
the use of artificial joint implants to restore motion and function of a joint- for example, total hip replacement is common orthopedic procedure performed on patients with degenerative joint disease (e.g. avascular necrosis or proximal femur)
49
Traction
process of putting a limb, bone, or group of muscles under tension with the use of weights and pulleys to align or immobilize the part
50
Computer Radiography
well suited for trauma wide exposure lattitudes ability to transfer images electronically
51
Close collimation & accurate centering in trauma
eliminates primary beam interaction w/ artifacts | reduce scatter radiation
52
Trauma Radiography
performed with conventional overhead tube | mobile (portable units
53
Types of mobile systems
battery driven, batter operated standard power, non-motor driven mobile c arm digital fluoroscopy
54
common procedures w/ c arm
cholangiography open/closed fx reduction hip pinning
55
C arm image orientation
required each time it is set up for use
56
Vertical Posteroanterior projection c arm
if patient is supine tube located under patient w/image intensifier on top minimizes exposure to neck and face
57
Which C arm position poses up to 100 times more dose to eyes of operator?
Vertical AP Projection C arm
58
What is the primary source of exposure to fluoroscopy staff?
scatter radiation frompatient
59
Trauma Horizontal beam w/ questionable spinal injury
Head and neck cannot be moved or elevated no supportive sponge use place IR below level of tabletop and move patient to edge of table to avoid cut off of posterior skull from beam divergence
60
Safety in trauma situations
always raise patient bed rails even if they were not originally up all equipment returned to original location no exposure should ever be taken with an unshielded person in the vicinity of primary beam
61
Alternative Imaging Modalities | Computed Tomography
increase speed | three dimensional reconstruction (useful in assessing skull trauma)
62
Sonography
Early assessment trauma patients experienced blunt abdominal injury detect free fluid or blood in abdomen modality of choice in trauma of female reproductive system
63
Nuclear Medicine
pulmonary embolus, testicular tortion, and gastrointestinal bleeding blood flow assessed through radionuclide injection
64
Angiography
used when study indicates aortic arch trauma
64
Blowout/tripod fx
Direct blow to the orbit, maxilla, and or zygoma creates fx of orbital floor
65
Epiphyseal fx
Fracture through epiphyseal plate. Most easily fx sites of long bones in children.
67
Tuft/burst fx
Comminuted fx if distal phalanx caused by crushing blow to distal finger or thumb.
68
C arm placement with tube in vertical AP position
can increase OID
69
Cine Loop images
images recorded in rapid succession while contrast medium is injected and displayed as a moving (cine) image.
70
snapshot/digital spot mode
activates a digital spot which results in a higher quality computer-enhanced image as compared to held fluoro images.
71
Digital spot film
acquires a single static radiographic image w/low radiation dose.
72
.5 mm lead apron
reduces exposure by a factor of 50 or more over the diagnostic x ray energy range
73
Boost Feature Fluoroscopy
provides brighter image for patient with large body habitus. Also increases radiation (mA) exposure to pt. and surgical team 3-4 x's that of standard fluoro
74
Which method is preferred with C arm use AEC or Manual?
AEC
74
Operative Cholangiography
2-3 images are obtained in slightly different positions. AP, slight RPO, and slight LPO
75
Three principals when performing trauma or mobile radiography
Two projections 90 degrees to each other Entire structure or trauma are on IR Maintain safety of patient, health care providers, and public
