Thoracic Wall Flashcards
Thoracocentesis
Remove fluid between ICS 8 or 9 in midaxillary line to avoid lungs, superior to rib 9 or 10
Superior to upper border
Intercostal nerve block
In ICS, blood 2 adjacent nervesT
Thoracostomy
Remove fluid (down) or air (down) in ICS 4 or 5, midaxillary
Superior to upper border
Sternectomy
To access thorax
Sternum
Used for bone marrow graft
Pectus carinatum
Sternum protrudes
Pectus excavatum
Sternum caves in
Paradoxical movement of hemidiaphragms
Damage to phrenic nerve
Cervical supernumeral rib
C7 vertebrae
Can compress inferior trunk (C8-T1) or subclavian artery, causing ischemia
Lumbar supernumeral rib
Often misdiagnosed as L1 transverse process fracture
Flail chest
Caused by multiple rib fractures, paradoxical lung movement
True ribs
1-7
False ribs
Do not articulate directly with sternum, connected to seventh costocartilage at costochondral join
8-10
Floating ribs
11-12
Do not articulate with sternum at all
Ribs 1&2
Muscle attachment sites for ant & mid (1) and post (2) scalene muscle
Anterior scalene
Anterior = subclavian vein
Posterior = subclavian artery
Polymastia
Extra breasts
Amastia
Missing breast
Polythelia
