Correct Answer is D
Explanation
Choice A rationale
Ankylosis refers to the stiffening and immobility of a joint due to fusion of the bones. This condition is typically caused by chronic inflammation or injury, leading to bone remodeling and eventual bridging of the joint space. It is a pathological process that restricts movement and is not a normal physiological adaptation during pregnancy.
Choice B rationale
Scoliosis is an abnormal lateral curvature of the spine, often accompanied by rotation of the vertebrae. It can be congenital, neuromuscular, or idiopathic. This spinal deformity deviates from the normal sagittal plane alignment and is not a typical physiological compensatory mechanism for the gravid uterus.
Choice C rationale
Kyphosis is an excessive outward curvature of the thoracic spine, resulting in a hunched back appearance. While some degree of thoracic kyphosis is normal, an exaggerated curve can be pathological. It does not represent the compensatory postural change seen in pregnant women, which primarily involves the lumbar region.
Choice D rationale
Lordosis is an increased inward curvature of the lumbar spine. During pregnancy, as the uterus enlarges anteriorly, the woman's center of gravity shifts forward. To maintain balance and prevent falling, the abdominal muscles stretch and the lumbar spine accentuates its inward curve, which is known as lordosis, a physiological adaptation.
