When screening for scoliosis, which observation provides the best view of spinal curvature?

• A. Have her bend at the waist to inspect for asymmetry of the scapulae
• B. Stand sideways to assess kyphosis
• C. Rotate the shoulders to observe uneven height
• D. Have her climb stairs and observe from behind

Answer: (A)

The essential idea is that the forward-bend view best reveals scoliosis because it highlights the spinal rotation that causes a rib hump and uneven scapulae. When the patient bends at the waist, the curvature of the spine becomes more apparent, making asymmetry in the scapulae and rib cage easier to see. So observing for scapular asymmetry during a forward bend directly exposes the curvature that scoliosis produces. Looking from the side checks kyphosis, not lateral curvature; rotating the shoulders or watching from behind during other activities won’t reliably reveal the spinal curve.
