Arrange the following postural deformities in a sequential order from toe to head:

(A) Hump Back/Kyphosis
(B) Genu Varum
(C) Pes Planus
(D) Hollow Back

Choose the correct answer from the options given below :

The correct option is (C), (B), (D), (A).

To arrange these postural deformities in sequential order from toe (lowest part of the body) to head (highest part of the body), we can examine the anatomical location of each deformity:

1. Pes Planus (C): Commonly known as "flat feet," this deformity involves the flattening of the longitudinal arches of the foot. Since the foot is the lowest anatomical region mentioned, this comes first at the bottom (toe/foot level).

2. Genu Varum (B): Commonly referred to as "bow-legs," this is a physical deformity marked by outward bowing at the knee. The knee is located directly above the foot/ankle region, making this the second deformity in the sequence.

3. Hollow Back (D): Also known as lordosis, this deformity represents an excessive inward curvature of the lumbar spine (lower back). The lower back is located above the knees but below the upper back.

4. Hump Back/Kyphosis (A): This refers to an exaggerated forward rounding or curvature of the thoracic spine (upper back/shoulders region), which is located closest to the head among all the options.

Therefore, tracing the deformities upward from toe to head gives the sequence: Pes Planus (Foot) → Genu Varum (Knee) → Hollow Back (Lower Back) → Hump Back/Kyphosis (Upper Back), which corresponds to the order (C), (B), (D), (A).
