Q

Rib Fractures

Most common?

What can it cause?

A

MOst commonly fractured ribs are the Middle ribs, at their weakest locus, just anterior to the costal angle.

Rib fracture can damage internal organs and produce severe pain with respiration, coughing, laughing, and sneezing

20
Q

Extra ribs are called?

do they cause problems?

A
21
Q

Thoracic Vertebrae go over again

what makes up the joint?

A
27
Q

Rib 1 joint type?

Rib 2-7?

Ligaments?

A
  • Rib 1 Synchondrosis
  • Rib 2-7 synovial planar
    • Anterior radiate sternocostal L.
    • Posterior radiate sternocostal L.
28
Q

Costovertebral joints?

A

Synovial planar

  • Radiate L. (head of the rib to vertebral body)
  • Intraarticular L. (head of rib to intervertebral disk)
  • Articular capsule (strongest anteriorly as the radiate L.)
29
Q

Costotransverse Joints

A

Costotransverse (synovial planar)

  • Lateral costotransverse L. (tubercle of the rib to the transverse process)
  • Superior Costotransverse L. (neck of the rib to the transverse process one vertebral segment superiorly)
30
Q

Head of rib articulates with what specifically?

Articulating facet of the costal tubercle?

A
31
Q

what causes increased thoracic volume (what does this cause?)

what joint does this happen at?

A
32
Q

Costochondral joints?

A

articulation between the ribs and costal cartilages

Synchondrosis

33
Q

Dislocation vs separation?

A

Dislocation refers to sternocostal joint

separation refers to constochondral joint

Q

Intercostal muscles?

A

External intercostal M.

Internal intercostal M.

Innermost intercostal M.

38
Q

External intercostal M.

location

O
I
A
N

A

External Intercostal M. (11 pair; anteriorly muscle fibers are replaced by the External Intercostal Membrane which overlies the Internal Intercostal M. Inferiorly the External Intercostal M. is continuous with the External Abdominal Oblique M.)

O: Inferior Border of Ribs (posteriorly)
I: Superior Border of Rib below (anteriorly)

A: Elevate Ribs
N: Intercostal N.

39
Q

Internal intercostal M.

Location

O

I

A
N

A

Internal Intercostal M. (11 pair; posteriorly muscle fibers are replaced by the Internal Intercostal Membrane which is visible in the Posterior Mediastinum immediately lateral to the Vertebral Column. Inferiorly the Internal Intercostal M. is continuous with the Internal Abdominal Oblique M.)
O: Inferior Border of Ribs (anteriorly)
I: Superior Border of Rib below (posteriorly)
A: Depress Ribs (interchondral Part Elevates Ribs)
N: Intercostal N.

40
Q

Innermost intercostal M.

location

O
I
A
N

A

Innermost Intercostal M. (11 pair; the deepest fibers of the Internal Intercostal M., separated from the Internal Intercostal Ms. by the Intercostal nerve and vessels)
O: Inferior border of Ribs
I: Superior border of Rib below
A: Undetermined, probably the same as Internal Intercostal M.
N: Intercostal N.

41
Q

Thoracentisis

A

Insertion of a hypodermic needle through the Intercostal musculature between ribs to obtain a fluid sample or drain small amounts of blood or fluid from the Pleural Cavity. The needle is inserted between ribs inferior to the Intercostal neurovascular bundle, but superior to the collateral branches.

42
Q

Insertion of Chest Tube

A

Insertion of a tube to remove large amounts of air, fluid, blood or pus from the Pleural Cavity. Tube is typically inserted in the 5th or 6th Intercostal Space

43
Q

Thoroscopy

A

Insertion of a Thoroscope into the Pleural Cavity through small incisions for visualizing and biopsying the space inside the Pleural Cavity.

44
Q
A

Transverse Thoracic M.

O: Posterior surface of the lower part of the Sternal Body and Xiphoid Process
I: Internal surface of the 2 – 6 Costal cartilages
A: Depress Ribs

N: Intercostal N.

45
Q
A

Subcostal M. (typically appear over the Innermost Intercostal M. on the Internal surface of the Posterior Thoracic Wall, near the Angles of the Ribs)
O: Inferior border of Rib
I: Superior border of Rib (1 to 2 Rib segments)
A: Probably act as the Internal Intercostal M.
N: Intercostal N.
