Sacrovertebral angle

Sacrovertebral angle is a term used in anatomy to describe the angle formed by the intersection of the sacrum and the vertebral column. This angle is significant in the study of spinal biomechanics and is often used as a measure of spinal curvature.

Etymology

The term "sacrovertebral" is derived from the Latin words "sacrum", which means "sacred bone", and "vertebra", which means "joint". The "angle" part of the term comes from the Latin "angulus", which means "corner" or "angle".

Anatomy

The sacrovertebral angle is formed by the intersection of the sacrum and the vertebral column. The sacrum is a large, triangular bone at the base of the spine and forms the upper, back part of the pelvic cavity. The vertebral column, also known as the spine, is a column of small bones, or vertebrae, that extend from the base of the skull to the tip of the tailbone.

The sacrovertebral angle is often used as a measure of spinal curvature. A normal sacrovertebral angle is typically between 30 and 40 degrees. An angle greater than 40 degrees is considered abnormal and may indicate a condition such as lordosis or kyphosis.

Clinical significance

The sacrovertebral angle is often measured in patients with spinal disorders or back pain. It can provide valuable information about the alignment of the spine and the severity of spinal curvature. Changes in the sacrovertebral angle can also indicate the progression or improvement of spinal conditions over time.

In addition, the sacrovertebral angle is often used in the planning and evaluation of spinal surgery. It can help surgeons determine the optimal approach and technique for surgery, and can also be used to evaluate the success of surgical interventions.
