Hüftgelenkpfanne

Hüftgelenkpfanne, also known as acetabulum, is a cup-shaped bone that forms part of the hip joint in the human body. It is located in the pelvis, specifically within the ilium bone. The acetabulum articulates with the head of the femur, forming the hip joint, which is a ball-and-socket joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation.

The acetabulum has a shallow, concave shape that accommodates the rounded head of the femur. This design allows for the distribution of forces across a larger area, reducing stress on the joint. The acetabulum is lined with a smooth, cartilage-covered surface called the labrum, which helps to deepen the socket and further distribute forces.

The hip joint is one of the most stable and durable joints in the body, thanks in part to the acetabulum's unique structure. However, like any joint, it can be susceptible to injury, wear, and disease. Conditions such as hip dysplasia, osteoarthritis, and fractures can affect the acetabulum and the hip joint as a whole.

In medical practice, the acetabulum is often a focus of treatment for hip-related issues. Procedures such as hip resurfacing, acetabular augmentation, and hip replacement can be performed to address problems within the acetabulum and restore function to the hip joint.
