There are 3 natural curvatures (curvatures) in the neck, back and waist regions of the spine.
Thanks to these curvatures, our spine minimizes the amount of load on it and can move flexibly.
The lumbar region consists of 5 vertebrae and sacrum (lumbar) bones.
Vertebrae overlapping; It forms the spinal canal through which the spinal cord and nerves pass.
The spine protects the spinal cord and nerves; It allows our body to move.
The vertebrae are attached to each other by pads that we call “disc” at the front and “facet” joints at the back.
Discs are actually jelly-like shock absorbers that prevent the vertebrae from rubbing against each other.
The task of the discs is to absorb the jolts that occur during walking, sitting and lifting loads, and to transfer the weight to the lower levels in a balanced manner by reducing the load on the vertebrae equally
The vertebrae are attached to each other from the back by two facet joints.

Facet joints are responsible for carrying 5-20% of body weight. If the amount of load due to abuse is increased, deteriorations and separations occur in the facet joints over time. Each disc consists of two parts: the outer part, which is woven with solid fibers, and the soft and jelly-like inner part. The robust exterior protects the soft and jelly-like interior and ensures flexible movement. Apart from these formations, the spine is supported by ligaments and muscles. Ligaments are tough bands that hold the discs and vertebrae in place. Muscles control movement, support the spine and provide stability. The spinal cord is responsible for transmitting the commands given by our brain to other parts of our body. The spinal cord terminates in the upper lumbar region and gives nerve branches to the leg muscles, urinary bladder and genitals. These nerves provide leg movement, sensation, urination, defecation, and your sexual function. |
