Lecture 7 (Skeleton of the chest, shoulder and arm)

Question 1

Sternum

Answer 1

Made of 3 parts

Manubrium, body, xiphoid process

Question 2

Xiphoid Process

Answer 2

Is cartialge until your 40
becomes bone after your 40s
not flexible with it is bone
harder to breath
harder to cough = incr risk of pneumonia

Question 3

Needle biopsy and chest tube

Answer 3

Biopsy = remove blood or tumor from lung
Chest tube = Goes into the chest to help inflate collapsed lungs
Both run along the upper edge of the rib, cuts down on truma to the check

Question 4

Chest surgery

Answer 4

Cut through the center of the sternum,
spread ribs, often fracture the ribs
Reunite the sternum, staple back together

Question 5

Caridopulmonary resuscitation (CPR)

Answer 5

Heart has stopped, breathing has stopped
Step 1
    -> Find sternal arach
Step 2
    -> Put hnads below it, hands sit on the body of the sternum, too low, break off the xiphoid process
Step 3
    ->  Press, Idea is force air out and bring air in, pump heart, take blood out, bring blood in
TOO high up = wont effect heart

Question 6

Fracture ribs

Answer 6

High risk in contact sports and airbags during collisions

Question 7

Separated Ribs

Answer 7

Rib separate from cartialage

Cartialage takes long time to heal

Question 8

Dislocate Ribs

Answer 8

Cartilage pulls away from sternum

Difficult to repair

Question 9

Clavicle

Answer 9

Long bone category
Curvature in bone = less snaping, 
But most common to fracture
Falling a particular way will snap it evertime 
Lateral portion is at the shoulder
Medial atriculation is the sternum 
Never tear the ligaments around clavicle

Question 10

Should joint

Answer 10

Easy to dislocate becase the glenoid process is very shallow
Allows for head of the humerus to slip out
Ligaments take years to mature
25 yrs old 100% to mature
Never strong in children
Can easily dislocate childs arm - child service
1% of fractures are of the scapula
