What physical finding is commonly expected in an adolescent with scoliosis?

In adolescents with scoliosis, a unilateral rib hump is a commonly expected physical finding. This occurs due to the abnormal curvature of the spine, which affects the alignment of the ribs. As the spine curves, particularly in a lateral direction, it can cause one side of the rib cage to protrude more than the other, resulting in a noticeable rib hump on the affected side when the person bends forward. This presentation can be assessed through the Adams forward bend test, which is a standard evaluation for scoliosis in adolescents.

The prominence of the rib hump can vary depending on the degree of curvature and the position of the body. A unilateral rib hump is a clear indicator of the asymmetry associated with scoliosis and is often more pronounced during physical examination in standing or bending positions. This physical characteristic serves as a critical sign for healthcare providers when diagnosing and assessing the severity of scoliosis in adolescents.
