Thoracic Spine Flashcards
True ribs
False ribs
Floating ribs
True ribs - directly attached to sternum. Increase length & curvature as you descend inferiority
False ribs - indirectly attached to sternum. Same as above
Floating ribs - do not attach to sternum. Small costal cartilage that terminates in lateral abdominal wall
Ribs 1- 7
Ribs 8,9 and 10
Ribs 11 - 12
Typical Ribs
Atypical Ribs
Have predictable head neck and Body that’s is the same regardless of which you are talking about
Neurovascular grove carries vasculature and nerves
Rib 1: only one facet two grooves for subclavian vessels
Rib 2: rough area for Serratus anterior muscle
Rib 10: only one facet
Rib 11 and 12; no neck, only one facet
Atypical has 1 or 2 in their number
Pump Handle, bucket handle, caliper motion
Ribs 1 -5: AP diameter moves like a pump
Ribs 5 - 10: Transverse diameter increases with inhalation
Rib 11- 12: Down and out motion
Rib Dysfunctions
Inhalation dysfunction: Rib is stuck up prefers to move up (ease) but does not move down (bind)
Key rib is bottom most rib is because if they are stuck up to get ‘em down you need to address 4
Exhalation dysfunction: Rib is stuck down prefers to move down (ease) but does not move up (bind)
Key rib is topmost because if they are stuck down to get ‘em up you need to address 2
Exhalation dysfunction
Muscle Moves Bone technique
Rib 1: Anterior scalene and middle scalene if contracted we can pull rib back up
Rib 2: Posterior scalene pull rib back up
Rib 3-5: Pectoralis Minor Pec
Ribs 6-9: Serratus Anterior Serratus
Rib 10 - 12: Latissimus Dorsi
Thoracic Anatomy
T3 spine of scapular
T7 Inferior angle of scapula
Diaphragm is the only major muscle attaches L1-L3 Ribs 6-12 Innervated by the Phrenic C3,C4,C5 keeps the diaphragm alive
