Thoracic Wall Flashcards
most important symptom of cardiac disease
chest pain
most common rib fracture
middle rib fractures (weakest anterior to angles)
what can cause diaphragmatic hernia?
lower rib fractures
1st rib fractures can cause?
damage to brachial plexus & subclavian vessels
multiple rib fractures allowing segment of thoracic wall to move freely; painful & impairs ventilation
flail chest; fixed with wires to prevent movement
surgical creation of opening through thoracic wall entering the pleural cavity
thoracotomy
H-shaped cuts through perichondrium of costal cartilage
anterior thoracotomy
thoracotomy through intercostal spaces 5-7
posterior thoracotomy
thoracotomy used in a pneumonectomy
lateral thoracotomy
where does a rib regenerate from?
periosteum
additional cervical or lumbar ribs or lacking 12th pair of ribs
supernumerary ribs
hard lump in epigastric fossa
ossified xiphoid processes (usually in elderly)
a crush injury can cause?
sternal fractures; 25-45% mortality due to visceral injury to heart/lungs
sternum divided at median plane, ribs allow spreading of chest
median sternotomy
used in transplants & blood dyscrasias; bone marrow needle biopsy
sternal biopsy
heart protusion (ectopia cordis) due to lack of sternal bar fusion
complete sternal cleft
small perforation in sternum
sternal foramen
receding or projecting of sternum evident in childhood
pectus excavatum/cavinatum
structures emerging from superior thoracic aperture are obstructed (lower neck & limb)
thoracic outlet syndrome
displacement of costal cartillage from sternum
sternocostal joint displacement
unilaterally in ribs 8, 9, 10 with damage to underlying structures (diaphragm/liver); lump-like deformity
interchondral joint displacement
dislocation between rib and costal cartillage in ribs 3-10
costochondrial junction dislocation
paradoxical movement; diaphragm ascends during inspiration and descends during expiration
paralysis of diaphragm (hemidiaphragm)
difficult breathing & how to make it better?
dypsnea —-> use accessory breathing muscles to expand thorax by leaning on arms/knees to allow muscles to act on the ribs
shingles skin lesion, disease of ganglia that causes burning pain in dermatome; rare motor neuropathy
herpes zoster
