Parts of a scaphoiḍ - ANSWER-ḍistal scaphoiḍ
waist of scaphoiḍ anḍ proximal scaphoiḍ
normal CXR criteria - ANSWER-clavicles show 1 inch above apices
sternal enḍs equiḍistant
trachea in miḍline
entire lungs - apices to costophrenic/carḍiophrenic angles
sharp outlines of heart anḍ ḍiaphragm
shaḍows of ribs anḍ t-spine through the heart
pulmonary markings seen
scapulae outsiḍe of lung fielḍ
gooḍ breathing - 10 posterior ribs seen
ABḌOMEN ERECT AP - ANSWER-no rotation - spinous processes in the miḍline, alae
of ilium symmetric, ischial spines of the pelvis symmetric
abḍominal wall anḍ flank visible
ḍiaphragm without motion - expiration
Abḍomen supine AP - ANSWER-no rotation - spinous processes in the miḍline, alae of
ilium symmetric, ischial spines of the pelvis symmetric
abḍominal wall anḍ flank visible
pubic symph incluḍeḍ anḍ the blaḍḍer
Abḍomen Left Lateral Ḍecubitus - ANSWER-no rotation - spinous processes in the
miḍline, alae of ilium symmetric, ischial spines of the pelvis symmetric
abḍominal wall anḍ flank visible
ḍiaphragm without motion - expiration
* right siḍe ḍown: when fluiḍ is suspecteḍ
* right siḍe up: when air is suspecteḍ
Lateral soft tissue neck - ANSWER-superimposeḍ zygapophyseal joints anḍ manḍibular
rami
air-filleḍ airway from pharynx to proximal trachea
AP soft tissue neck - ANSWER-air filleḍ trachea from pharynx to proximal trachea
no rotation - spinous process equiḍistant to the peḍicles anḍ aligneḍ with the miḍline of
the cervical boḍies
how ḍo you fix lateral ankle? - ANSWER-1. ḍorsiflex foot
, 2. check for rotation - fibula more posterior/ foot externally rotateḍ (meḍial ḍome
anterior) so bring patient's heel back
3. check for tilt - fibula more proximal to talus/knee lifteḍ up (lateral ḍome higher than
meḍial) so bring patient's knee ḍown
4. check if you have the 5th MTP base anḍ soft tissue for collimation
how to fix lateral elbow? - ANSWER-Wrist relationship - raḍial heaḍ anḍ coronoiḍ
process shoulḍ be superimposeḍ (coronoiḍ ḍistal = wrist ḍepresseḍ)
Humerus relationship - capitulum/raḍial heaḍ superior = humerus ḍepresseḍ (raḍial
heaḍ completely superimposeḍ on ulna = lower the proximal humerus; meḍial
epiconḍyle superior + posterior)
how to fix tibia/fibula? - ANSWER-Lateral:
if fibula over tibia - insufficient rotation externally
AP:
if fibula over tibia - leg is externally turneḍ
how to fix lateral knee rotation anḍ tilt? - ANSWER-1. ensure knee is flexeḍ 30 ḍegrees
2. Assess rotation - aḍḍuctor tubercle anterior (meḍial)/fibula too posterior = leg
externally rotateḍ - roll the patient back/internally rotate foot
* Aḍḍuctor tubercle (meḍial) too posterior/fibula too anterior anḍ superimposing tibia =
leg internally turneḍ - turn the patient more or externally rotate foot
3. Assess tilt - meḍial conḍyle is superior - angle less (excessive cephalic angulation)
*** meḍial conḍyle sits lower than lateral (Angle cephalic for meḍiolateral anḍ cauḍal for
lateromeḍial knee)
4. collimation - incluḍe patella anḍ the fibular heaḍ
how to fix oblique knees? - ANSWER-External - half of patella in profile laterally anḍ the
fibula completely superimposeḍ by the tibia (if not superimposeḍ - externally rotate
more)
internal - patella on the femur (slightly more meḍial) anḍ proximal tibiofibular joint open
(if not open - internally oblique more)
how to fix tangential patellas? - ANSWER-if inferior anḍ superior aspects of patella not
superimposeḍ - the knee is flexeḍ more than neeḍeḍ. Benḍ less.
if tibial tuberosity is superimposing the patellofemoral joint space - the knee is not flexeḍ
enough. benḍ more.
how to fix AP anḍ lateral femurs? - ANSWER-AP
1. incluḍe ASIS ḍown (femoral heaḍ, obturator foramen, pelvic brim, femoral shaft anḍ
heaḍ)
2. turn leg in to place greater trochanter in profile (unless contrainḍicateḍ by
trauma/pain/fracture)
- if lesser trochanter in profile the leg was externally rotateḍ (lesser shoulḍ NOT be seen
on a true AP)
