Q

What runs along the costal groove on the inferior side of the rib? Where? (superior to inferior)

A

vein
artery
nerve
-between the internal intercostal muscle and the innermost intercostal muscle

28
Q

Describe respiratory motion

A

Ribs 1-2, 8-10

  • move superioly and laterally
  • increase transverse diameter

ribs 3-7

  • move superiorly and anteriorly
  • increase anterior/posterior (A/P) diameter
29
Q

What are the rib motions?

A 
bucket handle
pump handle
caliper
torsional
non-physiologic
30
Q

What is caliper or pincer motion?

A

downward and posteriorly with inhalation; upward and anteriorly with exhalation
ribs 11-12

31
Q

What is subluxation?

A

incomplete or partial dislocation of a joint or organ

32
Q

Describe torsional movement

A

When T5 is rotated to the right on T6

  • posterior aspect of the right 6th rib turns externally
  • posterior aspect of the left sixth rib turns internally
  • anterior extremity of the right sixth rib becomes more flat with its inferior border sharp
  • anterior extremity of the left sixth rib having its superior margin accentuated
33
Q

Describe non-physiologic movement

A
  • due to trauma or repetative micro-trauma
  • rib becomes subluxed anteriorly or posteriorly
  • create abnormal, hypermobile ribs with the rib being carried more either anteriorly or posteriorly along the axis of motion between the costovertebral and the costotransverse articulations
  • one or more ribs lose the usual plasticity and become restricted in a deformed state
34
Q

What causes torsional movement?

A

due to the rotation of the thoracic spine

35
Q

What are respiratory rib dysfunctions?

A
  • inhalation restriction

- exhalation restriction

36
Q

What are structural rib dysfunctions?

A
  • torsion
  • anterior and posterior subluxation
  • superior subluxation of the first rib
  • anteroposterior compression
  • lateral compression
37
Q

What is inhalation dysfunction?

A

rib being held in a position of inhalation such that motion toward inhalation is more free and motion toward exhalation is restricted

38
Q

What is exhalation dysfunction?

A

rib being held in a position of exhalation such that motion toward exhalation is more free and motion toward inhalation is restricted

39
Q

What is the key rib?

A

rib that maintains a group of ribs in dysfunctional motion

-treat this rib FIRST

40
Q

What is the mnemonic for finding the key rib?

A

BITE
Bottom Inhalation
-if a group of ribs is found to have Inhalation dysfunction, the Bottom of the group is the key rib

Top Exhalation
-if a group of ribs is found to have Exhalation dysfunction, the Top of the group is the key rib

41
Q

What is exhalation restriction (inhalation dysfunction)?

A
  • a rib or group of ribs that ceases movement first during exhalation effort
  • key rib is bottom
  • assessment made as to whether the pump handle or bucket handle component is most restricted
42
Q

What is inhalation restriction (exhalation dysfunction)?

A
  • rib or group of ribs that ceases movement first during inhalation effort
  • key rib at top
  • assessment is made as to whether the pump handle or bucket handle component is most restricted
43
Q

Treatment for exhalation restriction (inhalation dysfunction)

A

ribs 1-10
-depress key rib with exhalation
ribs 11-12
-quadratus lumborum

44
Q

Treatment for inhalation restriction (exhalation dysfunction)

A 
rib 1 - ant/med scalene
rib 2 - post scalene
ribs 3-5 - pectoralis minor
ribs 6-8 - serratus anterior
ribs 9-10 - latissimus dorsi
ribs 11-12 - quadratus lumborum
45
Q

Causes of rib dysfunction

A
  • thoracic scoliosis or kyphosis
  • rib cage asymmetries, such as pectus excavatum or pectus carinatum
  • effects of bony diseases such as osteoporosis or osteoarthritis
  • increased chest wall diameter associated with illnesses such as COPD
  • effects of abnormal tensions in cervical rotator cuff or shoulder girdle muscles
  • effects of trauma to rib cage
  • effects of lifestyle and affective states such as slumping with depression
