How should the spinous processes present during thoracic/lumbar lateral bending relative to the contact?

• A. Medial and inferior from contact
• B. Lateral and inferior from contact
• C. Medial and superior from contact
• D. Lateral and superior from contact equal bilaterally

Answer: (D)

In thoracic and lumbar lateral bending, the vertebral segments move with a slight rotation in addition to the bend. As the spine flexes laterally, the spinous processes tend to shift upward and part laterally relative to the contact point you’re using to palpate. That means when you place your finger on a spinous process and the patient bends to either side, the process will appear more to the outside (lateral) and a bit higher (superior) from your contact, and this pattern should be similar on both sides. So the expected observation is that the spinous processes are lateral and superior from the contact, occurring equally on both sides. If you noticed a different pattern, it could indicate a variation in segmental motion or asymmetry in the spine.
