Which structural abnormality is associated with a wedge-shaped vertebral body due to disruption of epiphyseal rims and cartilaginous end plates?

Which structural abnormality is associated with a wedge-shaped vertebral body due to disruption of epiphyseal rims and cartilaginous end plates?

• A. Scheuermann's Kyphosis
• B. Postural Kyphosis
• C. Congenital Kyphosis
• D. Hyperkyphosis

Answer: (A)

Scheuermann's kyphosis is a structural adolescent kyphotic deformity caused by disruption of the epiphyseal rims and cartilaginous end plates, leading to anterior wedging of multiple adjacent thoracic vertebral bodies. This results in wedged vertebrae with irregular endplates (often with Schmorl nodes) and a rigid kyphosis that does not reduce with flexion. Postural kyphosis is flexible and improves when bending forward, congenital kyphosis arises from vertebral segmentation defects, and hyperkyphosis is a broader label that doesn’t specify the vertebral wedging pattern seen here.
