Understanding the anatomy of the lumbar vertebrae, sacrum, and coccyx, as well as the implications of a herniated disc, is crucial for individuals seeking to manage their spinal health and alleviate associated symptoms. Always consult a medical professional for accurate diagnosis and appropriate treatment recommendations. A herniated disc, also known as a slipped disc or ruptured disc, occurs when the nucleus pulposus (inner core) of an intervertebral disc protrudes through a tear in the annulus fibrosus (outer layer). This protrusion can exert pressure on adjacent nerves or the spinal cord, leading to various symptoms. Factors such as aging, repetitive stress, and improper lifting techniques can contribute to disc herniation.
