Is it true or false that Scheuermann's disease involves anterior wedging of at least three sequential vertebrae by at least five degrees?

• A. True
• B. False
• C. Not enough information
• D. Only applies to adults

Answer: (A)

The statement regarding Scheuermann's disease is true. This condition is characterized by a form of juvenile kyphosis that typically manifests during adolescence. A hallmark feature of Scheuermann's disease is the presence of anterior wedging in at least three consecutive thoracic vertebrae, where each affected vertebra is wedged by five degrees or more. This wedging can lead to a significant increase in thoracic kyphosis, which often results in postural changes that can lead to discomfort and other complications.

The identification of this specific degree of wedging helps differentiate Scheuermann's disease from other types of spinal deformities, such as postural kyphosis, which does not show the same pathological changes in the vertebrae. Understanding this criterion is crucial for diagnosis and management, as it influences therapeutic approaches and potential outcomes.
