Abnormal lateral spinal curvature of the body is:

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2020

Explanation

Scoliosis is the medical term for an abnormal lateral, or sideways, curvature of the spine.
This condition is characterized by a C-shaped or S-shaped curve when viewing the spine from the back.
It is distinct from curvatures in the sagittal (front-to-back) plane, such as kyphosis and lordosis.
The Adams forward bend test is a common screening method where asymmetry of the posterior chest wall indicates potential scoliosis.

Option A: Lordosis is an excessive inward (anterior) curvature of the spine, often called 'swayback'. It is a sagittal plane deformity, not a lateral one.
Option B: Kyphosis is an excessive outward (posterior) curvature of the thoracic spine, resulting in a 'humpback' or 'roundback' appearance. This is also a sagittal plane deformity.
Option D: Kypho-scoliosis is a compound deformity that involves both kyphosis (forward curvature) and scoliosis (lateral curvature). While it includes a lateral curve, 'scoliosis' is the more precise and specific term for a lateral curvature alone.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Spinal Curvature Deformities as background academic context rather than a clinical decision trigger.
Nurses play a key role in screening for scoliosis, particularly in school-aged children, using the Adams forward bend test to detect early signs of spinal asymmetry.
Patient and family education on the importance of brace compliance is a critical nursing function to prevent the progression of the curve and avoid surgery.
Assessing for and preventing skin breakdown under a brace is a vital patient safety intervention.

How to Approach the Question

First, break down the question to identify the core concept. The key phrase here is 'abnormal lateral spinal curvature'.
Define the directional term 'lateral'. In anatomy, lateral means 'to the side' or 'sideways'.
Systematically review the definitions of each option.
Lordosis is an inward ('swayback') curve.
Kyphosis is an outward ('humpback') curve.
Scoliosis is a lateral ('sideways') curve.
