Femoroacetabulargelenks

The femoroacetabular joint is a ball-and-socket joint located at the hip, formed by the articulation of the head of the femur (thighbone) with the acetabulum (socket) of the pelvis. This joint is crucial for hip movement and stability, allowing for a wide range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation. The joint is stabilized by a combination of ligaments, including the iliofemoral, pubofemoral, and ischiofemoral ligaments, as well as the labrum, a fibrocartilaginous structure that deepens the acetabulum.

The femoroacetabular joint is a synovial joint, meaning it is lined with a synovial membrane that produces synovial fluid to lubricate and nourish the joint. The joint capsule, which surrounds the joint, is reinforced by the transverse acetabular ligament, which helps to stabilize the acetabulum. The joint is innervated by the femoral and obturator nerves, and blood supply is provided by the medial and lateral circumflex femoral arteries.

Common conditions affecting the femoroacetabular joint include osteoarthritis, hip dysplasia, and fractures. Osteoarthritis is a degenerative condition characterized by the breakdown of cartilage in the joint, leading to pain, stiffness, and reduced range of motion. Hip dysplasia is a congenital condition in which the acetabulum is shallow or the femoral head is abnormally positioned, leading to osteoarthritis and pain. Fractures of the femoroacetabular joint can occur due to trauma and may require surgical intervention.

Treatment for femoroacetabular joint conditions depends on the specific diagnosis and severity of symptoms. Non-surgical treatments may include pain management, physical therapy, and lifestyle modifications. Surgical interventions may include joint replacement, acetabular reconstruction, or femoral neck osteotomy. Early diagnosis and treatment are essential for managing femoroacetabular joint conditions and maintaining hip function and quality of life.
