Ribs Flashcards
Typical
3-9 Similar in structure Each rib head to 2 facets Costotransverse articulation
Atypical
1, 2, 10, 11, 12 #1 –most curved, flat, no angle or groove, single facet with vertebral body #2 –demifacetswith T1 & T2 bodies, structure similar to #1 #10 –single facet with T10 body #11 & 12 –no tubercles, tapered ends, single facets w/ bodies (no costotransversearticulatios)
True
1-7 Attaches to sternum directly
False
8-10 Cartilage unites w/ that of rib 7 to attach to the sternum
Floating
11-12 Lack cartilage Float freely w/ muscle fibers
Pump Handle
Ribs 1-5 Transverse processes extend laterally Creates more of a TRANSVERSE AXISBucket
Bucket Handle
Ribs 6-10 Transverse processes angle back (posteriorly) Creates more of an AP AXIS
Caliper
Ribs 11 and 12 Vertical Axis (more or less)
Somatic Dysfunction: named for direction

Accessory Muscles of Inspiration
Scalenes SCM Pectoralis Latissimus Dorsi Serratus Anterior Serratus Post. Sup. QL
Major Muscles of Expiration
Passive Recoil Int Intercostals
Accessory Muscles of Expiration

“Take my breath away”
•QuadratusLumborum •Origin •Post. Iliac Crest •Iliolumbarligament •Insertion •Rib 12 •TP of L1-4 •Action •Fixation of rib 12 during respiration •Lateral flexion (side-bending) of the trunk
The ribs attach to the vertebral segments at the same level and
above (for example, rib 3 attaches at T2 and T3).
Anterior Rib Assessment
Can be in the seated or supine position (we will do supine today) Observe global breathing patterns Chest v abdominal breathing Rate, rhythm, ease of breathing Assess motion of the following areas: Ribs 1-5 (Pump handle motion) Ribs 6-10 (Bucket handle motion) Assess for the anterior counterstrain points
Rib Anterior Counterstrain Points

Posterior Rib Assessment
Best done in the prone position
Assess
Ribs 11-12 (Caliper motion)
Posterior counterstrainpoints
Rib Posterior Counterstrain Points

Anterior Rib Counterstrain
- Found along the mid clavicular line, or along the mid axillary line
- Often associated with exhaled sd
- Treated
- Knee contralateral
- flexion and side bending towards the tender point (more flexion with anterior points and more side bending with lateral points)
- Rotation is usually towards the tender point.

Posterior Rib Counterstrain
- Found along the posterior rib angles
- Often associated with inhaled sd
- Treated
- Knee ipsilateral
- slight extension, side bending away to elevate the posterior part of the rib,
- Rotation usually away from the rib tender point.

With MET and pump handle ribs add more
flexion
with MET and bucket handle ribs add more
side-bending
