<p>What are the two main functions of the thoracic cage?</p>

What are the two main functions of the thoracic cage?

To protect vital organs and to serve as an attachment site for muscles of the neck, back, upper abdomen, and shoulder girdle.

2
New cards

What holds the ribs together and maintains stability even if a rib is fractured?

Intercostal muscles.

3
New cards

What is a common symptom of thoracic cage fractures, especially when lying down?

Painful and laboured breathing.

4
New cards
<p>Which ribs are most commonly fractured?</p>

Which ribs are most commonly fractured?

Ribs 3–10.

5
New cards

Where is the weakest point of the rib?

Just anterior to the rib angle, along the axillary border.

6
New cards

Which radiographic view best visualizes rib fractures?

Oblique rib views.

7
New cards

What are the two main causes (etiologies) of rib fractures?

External force (e.g., falls, car accidents) and internal force (e.g., excessive coughing in elderly or osteoporotic patients).

8
New cards

How are non-displaced rib fractures usually treated?

They typically heal without intervention.

9
New cards

Name three possible complications of rib fractures.

Pneumothorax, cardiac perforation, flail chest.

10
New cards

What is flail chest?

A condition where three or more ribs are fractured in multiple places, causing unstable thoracic pressure and independent rib movement during breathing.

11
New cards

What are the three parts of the sternum?

Manubrium, body, and xiphoid process.

12
New cards
<p>Where do most sternal fractures occur?</p>

Where do most sternal fractures occur?

In the mid-body of the sternum.

13
New cards

What is the most common cause of sternal fractures?

Direct trauma from impacts or crushing injuries, often in motor vehicle collisions.

14
New cards

Give one example of a sternal stress fracture cause.

Overuse in athletes (e.g., wrestlers).

15
New cards

How are non-displaced sternal fractures usually treated?

Conservatively, without surgery.

16
New cards

Name three possible complications of sternal fractures.

Thoracic organ injury; Cardiac injury; Pneumothorax or punctured mediastinum.

17
New cards

What factors influence patient positioning for imaging a thoracic cage fracture?

Pain level, breathing difficulty, fracture location, suspected injury mechanism, and clinical signs.

18
New cards

Why are oblique rib views often used?

They better visualize rib fractures compared to standard views.

19
New cards

What should a technologist monitor for in thoracic cage fracture patients?

Respiratory distress and complications.

20
New cards

When should urgent intervention be sought?

If there are signs of pneumothorax or cardiac involvement.

21
New cards

What is the technologist’s priority when positioning a patient with suspected thoracic cage fractures?

Minimize discomfort while maximizing image quality.
