Steißwirbel

The Steißwirbel, also known as the coccyx, is the final segment of the vertebral column in humans and some other mammals. It is located at the base of the spine, below the sacrum, and is composed of three to five fused vertebrae. The coccyx serves several important functions in the body.

Anatomically, the coccyx is a triangular bone that tapers to a point at its lower end. It is connected to the sacrum via the sacrococcygeal ligament and is supported by the coccygeal muscles. The coccyx plays a crucial role in weight-bearing and provides a point of attachment for various muscles and ligaments.

In terms of clinical significance, the coccyx is often involved in injuries related to falls or trauma, particularly in the elderly population. Fractures of the coccyx can occur, and in severe cases, the coccyx may be completely dislocated or even amputated. Surgical intervention may be required to stabilize the spine and prevent further complications.

The coccyx is also a site of interest in forensic medicine, as it can provide valuable information about an individual's age, sex, and ancestry. Additionally, the coccyx has been the subject of various cultural and symbolic interpretations throughout history.

In summary, the Steißwirbel, or coccyx, is a vital component of the human skeletal system, playing essential roles in weight-bearing, muscle attachment, and overall spinal stability. Its clinical significance is notable, particularly in the context of trauma and forensic investigations.
