Question

Which of the following deformity is NOT related to lower extremities?

• A. Knock-Knee
• B. Scoliosis
• C. Bow-legs
• D. Flat-foot

Hint:

In the study of deformities, understanding the specific body parts they impact is crucial. Scoliosis primarily affects the spine, distinguishing it from other conditions that involve the legs or feet.

Answer 1

The Correct Option is B

To solve the problem, we need to identify which of the listed deformities does not affect the lower extremities of the body (i.e., hips, legs, knees, ankles, and feet).

1. Understanding Each Option:
- (A) Knock-Knee: A condition where the knees touch each other while standing straight, but the ankles do not. This affects the legs, especially the knees — clearly a lower extremity issue.
- (B) Scoliosis: This is a lateral curvature of the spine. It affects the vertebral column, particularly the thoracic and lumbar regions, and is not associated with lower limbs.
- (C) Bow-Legs: A condition where the legs curve outward at the knees while the feet and ankles touch. This is a deformity of the lower limbs.
- (D) Flat-foot: A condition where the arches of the feet collapse, causing the soles to touch the ground fully. Again, this is a deformity of the lower extremities.

2. Conclusion:
Out of the given options, only scoliosis is related to the spine and not the lower extremities.

Final Answer:
(B) Scoliosis
