Pathophysiology of pectoral Girdle Thoracic Cage Flashcards
What makes up the RTC
Supraspinatus
infraspinatus
teres minor
subscapularis
what does the scapula do
assists to anchor upper extremity and ROM of it
it is the origin of the RTC musculature
thick bone, requires high energy force to cause fracture
what are the MOA for scapular fracutres
MVC
fall from height
FOOSH
non-accidental trauma (KIDS)
what are the complications of scapula fractures
concerning for underlying pathologies due to MOI
- lung injuries
-brachial plexus injuries
- thoracic cage
- shoulder girdle(RTC)
-calvicular fracture
-fib fractures
what is a scapulothoracic dissociation
traumatic disruption of the structures grounding the scapula
how does a scapulothoracic dissociation present on x-rays
lateral displacement
what is thoracic outlet syndrome
compression of neruovascular bundle
may be due to soft tissue or bony abnormalities
what two primary muscles attach to the inferior aspect of the clavicle
pectoralis and deltoid
what type of joint is the AC joint
plane joint
synovial joint
what does the AC joint allow for
ROM of the scapula
what is the most common MOA for clavicular fracture
FOOSH or fall directly on the shoulder
what are the complications of clavicle fractures
compression of subclavian vein, artery and brachial plexus
with is the MOA for AC joint dislocation
fall and acromion being pushed under distal clavicle
what ligament tears with a AC joint dislocation
coracoclavicular ligament
what makes up the throacic cage
thoracic vertebrae
sternum and ribs
what is the purpose of the thoracic cage
protects lungs, pleura, trachea, esophagus, heart, diaphragm, part of the liver and kidneys
what ribs are false ribs
8, 9, 10 piggyback on the cartilage of rib 7
what ribs are floating ribs
ribs 11 and 12
What makes up the neurovascular bundle in the ribs
intercostal vein
ntercostal artery
intercostal nerve
what types of rib fractures are at higher risk for underling pathology
upper rib fractures
what are complications of rib fractures
pain
lung contusions
pneumothorax
hemopneumothorax
intra-abdominal injury
vascular injury - cardiac contusion
what can be compromised in rib fractures
ventilation
what can be secondary to rib fractures
pneumonia due to atelectasis
what is the MOA for sternal fractures
MVC
