Q. Which of these can be considered as fourth column of spine?
a. Abdomen muscle strength
b. Rib cage
c. Sternum
d. Paraspinal musculature
e. Psoas muscle
Answer -
c
The sternum has been considered as fourth column as it lends considerable support in the setting of multiple vertebral compression fractures. Conditions that affect sternum ( like multiple myelina or metastasis) thus increase chances of decreased resistance to subsequent thoracic kyphosis.
