C' curve is related to which physical deformity ?

Question

Accepted Answer

The correct option is (2):
Scoliosis is defined as an abnormal, sideways curvature of the spine when viewed from the back (in the coronal plane). This lateral bending of the vertebral column causes the spine to resemble either the letter 'S' or the letter 'C'. The "C" curve specifically represents a single, continuous, and unidirectional lateral curve in the spine, which is a common presentation of scoliosis, particularly in the lower back (lumbar spine). Therefore, any question referring to a lateral, C-shaped curvature is directly related to the physical deformity known as Scoliosis.

The incorrect option is (1):
Kyphosis is a spinal deformity characterized by an excessive outward or exaggerated *forward* curvature of the upper back, which is the thoracic spine. This condition is observed when viewing the spine from the side, as it affects the natural curve in the sagittal plane, resulting in a 'hunchback' appearance. The description of a lateral, side-to-side 'C' curve does not apply to the anteroposterior (front-to-back) rounding characteristic of Kyphosis.

The incorrect option is (3):
Lordosis is a spinal deformity where the lower back, or lumbar spine, exhibits an excessive *inward* or anterior curvature, often referred to as 'swayback.' This condition also affects the natural curves in the sagittal plane and is viewed from the side. Lordosis is distinct from the lateral 'C' or 'S' shape because it describes a pronounced frontward arch, rather than a deviation to the left or right side.

The incorrect option is (4):
The term 'Coliosis' is not a recognized medical or anatomical term for a spinal deformity. It is almost certainly a typographical error or a common misspelling of the correct term, 'Scoliosis.' For students preparing for exams, it is crucial to recognize the correct and accepted terminology for the three primary spinal deformities: Kyphosis, Lordosis, and Scoliosis.
