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
