DEFORMITIES OF THE THORAX

Question 1

The thorax in the __________ is wider than it is deep. Its Lateral diameter is larger than its anteroposterior diameter.

Answer 1

Normal Adult

Question 2

Note depression in the lower portion of the sternum. Compression of the heart and great vessels may cause murmurs.

Answer 2

Funnel Chest (Pectus Excavatum)

Question 3

There is an increased anteroposterior diameter. This shape is normal during infancy and often accompanies aging and chronic obstructive pulmonary disease.

Answer 3

Barrel chest

Question 4

The sternum is displaced anteriorly, increasing the anteroposterior diameter. The costal cartilages adjacent to the protruding sternum are depressed.

Answer 4

Pigeon Chest (Pectus Carinatum)

Question 5

Multiple rib fractures may result in paradoxical movements of the thorax. As descent of the diaphragm decreases intrathoracic pressure, on inspiration the injured are cave inward; on expiration, it moves outward.

Answer 5

Traumatic Flail Chest

Question 6

Abnormal spinal curvatures and vertebral rotation deform the chest. Distortion of the underlying lungs may make interpretation of lung findings very difficult.

Answer 6

Thoracic Kyphoscoliosis
