Kyphosis' deformity is also called

Question

Accepted Answer

The correct option is (2):
Kyphosis is medically defined as an exaggerated or excessive posterior (outward) curvature of the thoracic region of the spine. This common spinal deformity causes the upper back to appear visibly hunched or rounded forward, hence its most universally accepted and descriptive layperson's term is **Round back**. This forward hunching posture results from an increase in the natural outward curve of the thoracic spine, which can be caused by poor posture, developmental problems, or various diseases. Understanding this specific anatomical deviation—the excessive rounding—is the key conceptual link to identifying 'Round back' as the correct synonym for Kyphosis.

The incorrect option is (1):
Hollow back, which is formally known as **Lordosis**, describes a condition entirely opposite to Kyphosis. Lordosis is an exaggerated *inward* or anterior curvature of the spine, most typically occurring in the lumbar (lower back) region. This condition is visually characterized by an excessive arch above the buttocks, causing the abdomen to thrust forward and the back to appear "hollowed out." Students must remember that Kyphosis is the excessive outward curve, making the inward curve of Lordosis ('Hollow back') factually incorrect as an alternative name.

The incorrect option is (3):
Lateral back is not a standard medical or educational term for a spinal deformity; however, the term strongly suggests **Scoliosis**. Scoliosis is defined by an abnormal, side-to-side or lateral curvature of the spine, often accompanied by a rotation of the vertebrae. Unlike Kyphosis, which involves a curve in the sagittal plane (forward/backward), Scoliosis involves a deviation in the frontal plane (left/right). Because Kyphosis is a front-to-back deformity, a term relating to a sideways ('lateral') curve is conceptually incorrect as a synonym.

The incorrect option is (4):
Back curve is a general term that is too non-specific to accurately identify the Kyphosis deformity. The human spine naturally has several curves—the neck (cervical) and lower back (lumbar) curve inward, and the upper back (thoracic) curves slightly outward. Therefore, simply stating 'Back curve' does not communicate the critical information that the curve is *excessive* or abnormal. 'Round back' is the precise descriptive term that pinpoints the pathological, hunching nature of the Kyphosis condition.
