Radiology of the Pelvis Flashcards
(44 cards)
Identify the indidcated features of the pelvis
What view is shown in the provided image?
Normal AP Radiograph
Identify the indicated contou lines
What features are being pointed out by the lines on the radiograph?
This radiograph is in what view?
What is the importance of the normal pelvic inlet radiograph?
- Help detect:
- anterior or posterior displacement of bony pelvis structure
- rotation deformities
- sacral arch fractures
The provided radtiograph is in what view?
What are the benefits of this view?
Normal pelvic outlet radiograph
- Help detect
- hemipelvis elevation / superior or inferior displacement of bony pelvis structures
- sacral fractures
- SI joint widening
What is the most common method for classification of pelvic ring injury?
Young and Burgess classification
3 different types based on the direction of the force
- lateral
- stable (can support own weight & not do damage to themselves)
- rotationally unstable, vertically stable
- globally unstable
- anterior/posterior
- stable
- rotationally unstable, vertically stable
- globally unstable
- vertical shear
- visceral injuries, unstable
- combined
- variable
What tyep of ring injury is shown in the provided image?
Lateral compression type 1, AP radiograph
What type of fracture is shown in the provided image?
Arcuate line fracture
What type of pelvic ring fracture is shown in the provided image?
WHta
What type of fracture is shown in the provided image?
see a fracture on both side
What type of pelvic ring injury is shown in the provided image?
diastasis < 2.5 cm
What type of pelvic ring injury is shown in the provided image?
once the pubic symphysis diastasis is > 2.5 cm,
the sacrospinous & sacrotuberous ligaments are also ruptured
probably on a board
What type of pelvic ring injury is shown in the provided image?
additionally posterior ligaments of the SI joint
What type of pelvic ring injury is shown in the provided radiograph?
notice that the diastasis is not level
will rip sacrotuberous/spinous ligaments & anterior/posterior ligaments of the SI joint
What contour lines are shown in the provided radiograph?
They indicate what structure?
- yellow: ileopectineal line
- going to the pubic bone (anterior)
- purple: ileoischial line
- going to ischial tuberosity (posterior)
- green: anterior rim of acetabulum
- red: posterior rim of acetabulum
Identify the indicated regions
Identify the type of elementary acetabular fracture
What type of view is shown in the provided radiographs?
What is the usually appropriate next steps for
“Penetrating trauma, lower abdomen and pelvis. Suspected lower urinary tract trauma. Initial imaging”
Fluroscopy retrograde cytogrophy
CT pelvis with bladder contrast (CT cytography)
The provided image is an example of what imaging modality & what is the purpose of it?
- Retrograde cystogram
- catheter inserting fluid into the bladder the “wrong way”
- looking to see if any of the contrast leaks out
- Retrograde urethrogram
- same thing, looking for rupture of the urethra
What imaging technique is shown in the provided image?
Why is this type of imaging performed?
- CT cystography
- insert catheter & inflate the bladder balloon with
- looking for leakage in the fascial planes
What is the appropriate procedure for an adult or child with acute onset of scrotal pain. WIthout trauma, without antecedent mass?
What are you looking for?
US duplex doppler scrotum
Torsion vs. infection / Complication?
If torsion, about 6 hrs before lose testicle
Age of patient is important
What is the most common cause for acute scrotal pain in patients?
Epididymitis
Common in patients 19-25 & is overwhelmingly the etiology for acute scrotum pain in patients >25 yrs
Where should you assess the scrotum when determining epididymitis?
The infection travels retrograde (tail, body, head, then testicle - so assess the tail)
