Question

What is the term for an abnormal anterior lumbar spine curvature resulting in a sway back?

1) Kyphosis
2) Scoliosis
3) Lordosis
4) Osteoporosis

Answer 1

Lordosis is the term for an abnormal anterior lumbar spine curvature resulting in a sway back.

Step-by-step explanation:

The term for an abnormal anterior lumbar spine curvature resulting in a sway back is Lordosis.

Lordosis is characterized by an excessive anterior curvature of the lumbar region and is most commonly associated with obesity or late pregnancy. The accumulation of body weight in the abdominal region results in an anterior shift in the line of gravity, causing an anterior tilt of the pelvis and a pronounced enhancement of the lumbar curve.

Therefore, the correct answer is 3) Lordosis.
