Exaggerated convexity in thoracic region is called?

Appeared in: JODHPUR AIIMS SNO-2018

Explanation

Kyphosis is the medical term for an excessive outward (convex) curvature of the spine as it occurs in the thoracic and sacral regions.
This condition is commonly known as "humpback" or "round back" due to the visible rounding of the upper back.
While a normal thoracic spine has a convex curve of 20-50 degrees, a curve exceeding this range is defined as kyphosis or hyperkyphosis.
The image provided correctly illustrates this deformity as an exaggerated curve in the upper back.

Option B: Lordosis is an excessive inward (concave) curvature of the spine, not an outward (convex) one. It is the opposite type of curve.
Option C: Myelitis is the inflammation of the spinal cord, which is a neurological issue. It is not a structural deformity of the vertebral column.
Option D: Scoliosis is a lateral (sideways) curvature of the spine, creating an 'S' or 'C' shape. The question specifies a convexity, which refers to a forward-backward curve.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Abnormal Spinal Curvatures as background academic context rather than a clinical decision trigger.
Nurses perform postural assessments to screen for spinal deformities like kyphosis, especially in adolescents and older adults, who are at higher risk.
Early identification of kyphosis allows for timely intervention, such as physical therapy or bracing, to manage symptoms and prevent progression, which can otherwise lead to chronic pain and respiratory compromise.
Patient education is a key nursing role, involving teaching exercises to strengthen core and back muscles and promoting good posture to alleviate symptoms.

How to Approach the Question

First, break down the question to identify the key terms: "exaggerated convexity" and "thoracic region".
"Thoracic region" points to the upper or middle back.
"Convexity" describes a curve that bows outward, like the back of a spoon.
Recall the definitions of the common spinal deformities provided in the options.
Match the definition of an outward curve in the upper back with the correct term, which is Kyphosis.
Differentiate this from Lordosis (inward curve, lower back), Scoliosis (sideways curve), and Myelitis (inflammation, not a curve).
