acetabulären

Acetabulären refers to the acetabulum, which is the cup-shaped socket in the pelvis that articulates with the head of the femur, forming the hip joint. The acetabulum is part of the os coxae, or hip bone, and is located in the acetabular fossa, a depression on the lateral side of the pelvis. Its shape and size are crucial for the stability and mobility of the hip joint.

The acetabulum has a complex structure, including the ilium, ischium, and pubis bones, which contribute to its overall shape. The acetabular labrum, a fibrocartilaginous rim that surrounds the acetabulum, provides additional stability and cushioning for the joint. The acetabulum is lined with hyaline cartilage, which allows for smooth articulation with the femoral head.

The acetabulum plays a vital role in various movements, including flexion, extension, abduction, adduction, internal rotation, and external rotation of the hip. Its shape and size can be influenced by factors such as age, sex, and individual anatomy. Abnormalities in the acetabulum can lead to conditions like hip dysplasia, where the acetabulum is shallow or malformed, resulting in hip pain and mobility issues.

In clinical settings, the acetabulum is often assessed using imaging techniques such as X-rays, MRI, or CT scans to evaluate its structure and function. Understanding the anatomy and function of the acetabulum is essential for diagnosing and treating hip-related conditions.
