The lumbar spine consists of 5 vertebrae located below the dorsal and anterior to the sacrococcygeal vertebrae. The lumbosacral column is the structural basis of the human weight support, which is why it is continually exposed to enormous mechanical stresses. These tensions are supported by the lumbar vertebrae and by a fibrocartilaginous disk (which serves to absorb the blows) located between them.
Factors such as:
- The passage of the years
- Bad postures
- The overweight
- And staying in the same posture for prolonged periods
- These factors can change the alignment of the spine and hip; These factors, added to overloads,
- sudden movements or impacts, can degenerate the discs and narrow the space between the vertebrae causing serious discomfort.

90% of the hernias are located between the lumbar vertebrae L4-L5 and L5-S1, because there is a change of curvature of the spine – from lumbar lordosis to sacrosanct kyphosis – and when that curvature – from convex to concave – Is forced to leave the axis of the spine, either by being overweight or by recurring bad postures, this causes an increase in weight that must be borne by certain soft structures in that area, such as the discs, which are not designed to hold both Weight and end up injured.
When there is lumbar disc herniation at the level of the vertebrae L4 and L5 – which are part of the structure that forms the sciatic nerve, which are five roots causes root-type pain (sensation of electric discharge, throbbing, burning, burning, tingling ) That is felt at the level of the gluteus, the posterior aspect of the thigh, the anterolateral aspect of the leg, and may even extend to the dorsum of the foot and to one of the toes of the affected side. This creates a serious discomfort in the patient that affects his quality of life, and certain positions increase the pain, which makes us suspect that he has lumbotitica caused by a herniated disc.
