17: Ribs Flashcards
What does the head of a typical rib articulate with?
Superior costal facet of same # vertebrae + inferior costal facet of vertebrae above
What does the rib tubercle articulate with?
Transverse process of corresponding vertebra
What is unique about ribs 11 and 12
No tubercles
Which ribs are considered typical?
3-9
True, false, and floating ribs
True: 1-7
False: 8-10
Floating: 11-12
Two principles of MET used to treat rib SDs
- Respiratory assistance
2. Using muscle force to move one region of body to achieve movement of another region/bone
O and I of external, internal, and innermost intercostals
O: inferior border of ribs
I: superior border of ribs
External vs internal and innermost intercostal action
External: elevate ribs
Internal/innermost: depress ribs
Order of vessels running in the costal groove from most superior to inferior
Vein -> artery -> nerve
Between which two layers of muscles is the intercostal bundle found?
Between internal and innermost intercostals
Inhalation vs exhalation SD
Inhalation: rib held in a position such that inhalation is more free
Exhalation: rib held in a position such that exhalation is more free
Key rib of an inhalation dysfunction
At the bottom of the group
What assessment must be made once you determine if an SD is inhalation or exhalation SD?
Assess whether the pump-handle or bucket-handle component is more restricted
Six muscles used for exhaled rib SD and which ribs they treat
1: anterior/medial scalene
2: posterior scalene
3-5: pec minor
6-8: serratus anterior
9-10: lat dorsi
11-12: quadratus lumborum
