Arthrocace coxarum refers to the joint cavity found in the hip joint, specifically between the femoral head (the ball-shaped end of the thigh bone) and the acetabulum (the cup-shaped socket in the pelvis). The term is derived from the Latin words "arthrocace," which means joint cavity, and "coxarum," which pertains to the hip.
The hip joint, formed at the junction of the femur and pelvic bones, is a synovial joint that allows for a wide range of movement, such as flexion, extension, abduction, adduction, and rotation. The joint cavity, or arthrocace coxarum, is the space within this joint where the articulating surfaces of the femur and acetabulum meet.
The arthrocace coxarum is lined with a thin, lubricating synovial membrane, which secretes synovial fluid to reduce friction between the joint surfaces, aiding in smooth movement. The femoral head and acetabulum are protected by articular cartilage, a smooth, resilient tissue that cushions the bones and provides shock absorption.
Injuries or conditions affecting the arthrocace coxarum can lead to hip joint pain, stiffness, and limited mobility. Disorders like osteoarthritis, rheumatoid arthritis, hip labral tears, or avascular necrosis may necessitate medical intervention, including physical therapy, medication, or in severe cases, surgical procedures such as hip replacement.
Understanding the structure and function of the arthrocace coxarum is crucial for healthcare professionals to diagnose and treat hip-related issues effectively.
