Lendenkrümmung

Lendenkrümmung, also known as lumbar lordosis, is a normal physiological curvature of the spine in the lower back region. It is one of the primary curves of the spine, along with the cervical lordosis in the neck and the thoracic kyphosis in the upper back. The lumbar lordosis is essential for maintaining the spine's stability and allowing for the natural arch of the back, which is crucial for posture and mobility.

The lumbar spine consists of five vertebrae, and the lordosis is formed by the natural tilt of these vertebrae. This curve helps to distribute the body's weight evenly and provides a stable base for the pelvis and lower extremities. It also allows for the flexibility needed for activities such as bending, twisting, and lifting.

Lendenkrümmung is typically most pronounced in the middle of the lumbar spine, around the level of the third or fourth lumbar vertebra. This area is often referred to as the "lumbar lordotic curve." The curve is maintained by a combination of muscular and ligamentous structures, including the erector spinae muscles and the interspinous ligaments.

In some cases, the lumbar lordosis may become exaggerated or altered due to various factors, such as aging, pregnancy, or certain medical conditions. This can lead to discomfort or pain, which may require medical intervention. However, the normal lumbar lordosis is a fundamental aspect of spinal health and should be preserved whenever possible.
