A

Mid/lower costal segments

28
Q

Wait, but if it isn’t bucket handle or pump handle motion, what is happening at ribs 11 and 12?!

A

Caliper

29
Q

Torsional motion (internal/external) occurs in all costal segments however is most dominant in the …

A

mid/lower ribs

30
Q

Ribs follow a (convex/ concave) rule

A

Convex

31
Q

When you go into thoracic flexion, you have an over all ________ torsion of the ribs.

A

Internal

32
Q

Bony architecture plays a larger role in rib motions during (flexion/ extension)

A

Extension

33
Q

The normal response of the ribs to thoracic extension is …

A

External torsion

34
Q

When i rotate to the left, the rib on the right will go into _________ torsion and the rib on the left will go into _________ torsion.

A

Rotate left
Right rib- internal torsion
Left rib- external torsion

35
Q

When I side bend to the right, my right rib goes into _______ torsion while my left rib goes into________.

A

Side bend right
Right rib- internal
Left rib- external

36
Q

A dysfunctional key rib during inhalation is the (top/ bottom) rib, and during exhalation is the (top/ bottom) rib that is stuck in place.

A

Inhalation- top

Exhalation- bottom

37
Q

As you progress down the spine, rib angles grow more …

A

Lateral

38
Q

What is the mechanism or injury for superior first rib subluxation? What are its symptoms?

A 
Mechanism of Injury: Traumatic lateral neck flexion
• 5-6 mm higher 
• Marked tenderness 
• Diminished depression upon exhalation 
• Scalene hypertonicity
39
Q

What is the mechanism or injury for anterior rib subluxation? What are its symptoms?

A

Mechanism of Injury: Traumatic force to posterior rib angle

  • More prominent anteriorly
  • Less prominent rib angle
  • Tender iliocostalis muscle
  • Limits inhalation/exhalation
40
Q

What is the mechanism or injury for posterior rib subluxation? What are its symptoms?

A

Mechanism of Injury: Traumatic force to anterior extremity of the rib

  • More prominent Rib Angle
  • Less prominent anteriorly
  • Tender iliocostalis muscle
  • Limits inhalation/exhalation
41
Q

What is the mechanism or injury for anterior-posterior rib compression? What are its symptoms?

A

Mechanism of Injury: Traumatic A-P compression of the costal cage

  • Mid-axillary line prominence
  • Diminished A/P prominence
  • Tender iliocostalis muscle
  • Limits inhalation/exhalation
42
Q

What is the mechanism or injury for lateral rib compression? What are its symptoms?

A

Mechanism of Injury: Traumatic lateral compression of the costal cage

• Diminished mid-axillary line
prominence 
• A/P prominence 
• Tender iliocostalis muscle 
• Limits inhalation/exhalation
43
Q

What is the mechanism or injury for internal rib torsion? What are its symptoms?

A

Mechanism of Injury: Combined flexion/rotation injury (FRS)

  • Inferior border more prominent posteriorly
  • Superior border less prominent posteriorly
  • Tender iliocostalis muscle
  • Limits primarily inhalation
44
Q

What is the mechanism or injury for external rib torsion? What are its symptoms?

A

Mechanism of Injury: Combined extension/rotation injury (ERS)

• Superior border more prominent posteriorly 
• Inferior border less prominent
posteriorly 
• Tender iliocostalis muscle 
• Limits primarily exhalation
45
Q

What is the mechanism or injury for a laterally flexed rib? What are its symptoms?

A

Mechanism of Injury: Traumatic lateral trunk flexion

  • Mid-axillary prominence of rib shaft
  • Intercostal space asymmetry above/below rib shaft
  • Tender iliocostalis muscle
  • Limits primarily exhalation
