how can you recognize a skeletally immature pelvis XR?
physis
triradiate cartilage still open
AP Pelvis
what does the teardrop represent
medial wall of acetabulum.
AP Pelvis
Iliopectineal line represents
anterior column of acetabulum
AP Pelvis
ilio-ischial line represents
posterior column of acetabulum
acetabulum is tilted which way
anteverted
Shenton’s Arc (or line)
important on AP pelvis
helps w/determining if there is a dislocation. would be broken in dislocation
AP pelvis skeletally imature lines
shentons arc
Hilgenreiner’s line
perkin’s line
Hilgenreiner’s line - describe
Horizontal line through triradiate cartilage
Perkins line - describe
perpendicular to hilgenreiner’s line, through lateral most aspect of the acetabular roof
in relationship to hilgenreiner’s land perkins’ lines, where should a normal hip be?
below hilgenreiner’s line and medial to perkin’s line
what pelvis view is basically a straight AP view of sacrum?
pelvic outlet view.
On pelvic outlet view, what should line up with S2?
pubic symphysis
Judet views are named based on
the injured side
judet views are
obturator oblique
iliac oblique
Judet view
obturator oblique is the view you would want to evaluate the
anterior column, which is the iliopectineal line
also view you want for posterior wall.
Judet view
iliac oblique is the view you would want to evaluate the
anterior wall
also posterior column, which is the ilioischial line
how to remember judder view
POW
p/w: posterior wall
O: obturator oblique
what 3 views should you get for the ankle?
AP
mortise
Lateral
how does mortise differ from AP
you internally rotate at knee a little to get the toes to point forward. to get purely anterior of mortise
what indicates a good lateral view of the ankle?
look at the talar dome, make sure it has good overlap with tibia
How can you tell if you have an AP view of scapula?
scapula is protracted forward a little - 30 degrees of ante version
what shoulder view would overcome the anterior tilt of the scapula?
Grashey
any time you are evaluating congruency of glenohumeral joint, you should get what view
axillary view
this view tells you where the glenoid and humerus are articulating
If it’s too hard to abduct arm for axillary view - get a?
velpeau view
