Hippobosca equina

Hip Socket

The hip socket, also known as the acetabulum, is a deep, cup-shaped structure located on the lateral aspect of the pelvis. It is a key component of the hip joint, one of the most important and complex joints in the human body.

Anatomy

The hip socket is formed by the fusion of three bones: the ilium, the ischium, and the pubis. These bones converge to form a rounded cavity, or socket, that accommodates the head of the femur (thigh bone), thus forming the hip joint. The inner surface of the hip socket is lined with a thin layer of cartilage, which helps to reduce friction and absorb shock during movement.

Function

The primary function of the hip socket is to provide a stable support for the femur, allowing for a wide range of movements including flexion, extension, abduction, adduction, internal rotation, and external rotation. The unique structure of the hip socket also contributes to the overall stability of the hip joint, preventing dislocation under normal circumstances.

Clinical Significance

Conditions affecting the hip socket can have a significant impact on mobility and quality of life. These include osteoarthritis, hip dysplasia, hip impingement, and hip fractures. Treatment options for these conditions range from conservative management with physical therapy and pain management, to surgical interventions such as hip arthroscopy, hip resurfacing, or total hip replacement.
