Kyphosis refers to curvatures in the spine's anteroposterior axis (colloquially humpback). This disorder interferes with the sagittal equilibrium, which has recently become very critical. Sagittal balance is the harmony of the natural spinal alignment's cervical lordosis, thoracic kyphosis, and lumbar lordosis. If everything is in order, the vertical line drawn from the centre of the cervical 7th vertebra should finish at the sacral promotorium. This balance must be achieved in the treatment.
This spine curvature can result in a variety of problems, including trouble breathing, weariness, back pain, hump appearance, tenderness, and stiffness. The curvature can impair lung capacity, produce extreme pain, weaken muscles, and potentially result in catastrophic neurological symptoms such as paralysis. The hump back deformity is the most well-known.
