Question | Answer |
---|---|
manubrium | 2-5cm, aka handle, connects to rib 1 |
body of sternum | aka sword, corpus gladiolus, 4-10cm |
xiphoid process | aka swordlike |
jugular notch | houses veins, arteries; t2, t3 |
sternal angle | t4, t5 attaches to rib 2 |
true ribs | 1-7 |
false ribs | 8-12 |
post portion of ribs | superior |
anterior portion of ribs | inferior |
costovertebral articulation | head of rib attaches to body of vertebrae, synovial gliding, diarthrodial |
costotransverse articulation | tubercle of rib articulates with transverse process, diarthrodial |
costochondral joint | articulation betwwen cartilage and rib, immoveable (synarthrosis) |
sternocostal joint | articulation betwwen sternum and cartilage, 1st one synarthrodial;2nd-7th are synovial gliding, diarthrodial (freely moveable) |
interchondral joints | cartilage articulates with cartilage, 6th-9th ribs, synovial gliding |
sternoclavicular joint | between sternum and clavicle, synovial gliding |
sternum RAO CR | T7 (halfway b/t sternal notch and xiphoid process) and 1" to left of mid sag plane |
sternum RAO positioning | 15-20 degree oblique (less obliquity for larger pt) sid 40", 10x12 |
rao sternum breathing | use breathing tech and 3-4 sec exposure time, low (65-70) kvp |
sternum lat cr | top of cass 1" above sternal notch, slightly post to sternum |
sternum lat positioning | 72 sid, 10x12 cass, suspend on inspiration, low kvp, roll shoulders back, hands behind back |
ribs oblique(axillary) CR | above diaphragm, cr t7, top of cass 1.5" above shoulders and 1" lateral |
ribs oblique positioning | rt ant pain do LAO, lt ant pain do RAO; rt post pain do RPO, lt post pain do LPO, suspend on inspiration, 72 sid (most clinical sites will want LAO and RAO for ant pain and LPO and RPO for post pain with side of injury/pain the side of interest) |
ribs ap below diaphragm cr | CR T10, 40 sid, 14x17 cw, mid sag, must include ribs 8-12 |
ribs marker | mark side of injury, interest |
sternum pa oblique moore method | cr 20-25 degrees at t7, 1" to left of spine |
rib routine | ap above diaphragm, 1 or 2 obliques, possibly pa chest |
sternum routine | rao and lat |
SC jt routine | pa and ant oblique |
intrathoracic injuries | mediastinal shift, hemo and pneumothorax |
costal cartilage of ribs 1-7 | attach directly to sternum |
costal cartilage of ribs 8-10 | attach to costal cartilage of 7th rib |
rid head | posterior end |
sternal end of rib | anterior end |
SC jt | only thing that connects the upper extermity and shoulder girdle to the thorax |
2nd costocartilage | connects at sternal angle, connects to manubrium and body |
widest part of thorax | at 8th and 9th ribs |
why is rao preferred for sternum | because throws the sternum over the heart |
max filtration for mammo | 1mm Al |
breast cancer found most often | in UOQ |
