Postural kyphosis is a condition that affects the natural curves of the spinal cord. The spine is composed of three segments, each with its own unique curve. The upper cervical spine and lower lumbar spine have c-shaped curves, while the middle segment, known as the thoracic spine, forms a reverse c-shaped curve. However, problems arise when any part of the spine curves excessively or inadequately. Kyphosis occurs when the thoracic spine curves more than it should.
Although kyphosis can affect individuals of any age, it is most commonly observed in adolescents and young adults. It is crucial to understand the causes, symptoms, and potential treatments associated with this condition.
Anatomy of the Spine
The spine, also known as the vertebral column, is made up of 24 small rectangular-shaped bones called vertebrae. These vertebrae are stacked on top of each other, forming the natural curves that are present in each segment of the spine. The primary function of the vertebrae is to provide support and protection for the spinal cord.
Furthermore, the vertebrae are interconnected to create a canal, known as the spinal canal, which serves as an extra layer of protection for the spinal cord. This canal helps to safeguard the delicate nerves and tissues of the spinal cord from potential injuries.
In addition to the vertebrae, there are intervertebral disks that sit between each pair of vertebrae. These disks act as shock absorbers and provide cushioning for the bones. They play a crucial role in maintaining the flexibility and mobility of the spine, allowing us to move and bend our back without discomfort.
Understanding Postural Kyphosis
Postural kyphosis refers to an abnormal curvature of the thoracic spine, which naturally forms a reverse c-shaped curve. Typically, this curve ranges between 20 and 45 degrees. However, when the curve exceeds the average range, it is known as hyperkyphosis in medical terminology. Nevertheless, healthcare experts often use the term kyphosis to describe any excessive curvature of the thoracic spine.
