Articulatio coxae

Articulatio coxae is the scientific term for the hip joint, a ball-and-socket type joint that connects the pelvis to the femur, or thigh bone. This joint is one of the most important in the human body, as it bears the weight of the upper body and facilitates movement and balance.

Anatomy

The articulatio coxae is composed of two main parts: the acetabulum of the pelvis and the head of the femur. The acetabulum is a deep, cup-shaped socket that holds the rounded head of the femur. This design allows for a wide range of motion while maintaining stability.

The joint is surrounded by a capsule of fibrous tissue, which is lined with synovial membrane. This membrane produces synovial fluid, which lubricates the joint and reduces friction during movement.

Function

The primary function of the articulatio coxae is to support the weight of the upper body and to facilitate movement. It allows for a wide range of motion, including flexion and extension (forward and backward movement), abduction and adduction (sideways movement), and rotation.

Clinical significance

Due to its weight-bearing role, the articulatio coxae is susceptible to various conditions and injuries. These include osteoarthritis, hip fracture, and hip dysplasia. Treatment for these conditions may involve medication, physical therapy, or surgery, including hip replacement.
