Artikulationsfläche

Artikulationsfläche refers to the point of contact between two or more bones that form a joint. This specialized surface is typically covered with articular cartilage, a smooth, resilient tissue that reduces friction and absorbs shock during movement. The shape and structure of the artikulationsfläche are critical in determining the type and range of motion of a joint. For instance, ball-and-socket joints, like the hip and shoulder, have a broad, rounded artikulationsfläche on one bone fitting into a cup-like depression on another, allowing for a wide arc of movement. Hinge joints, such as the elbow and knee, possess flatter or slightly curved artikulationsflächen that permit movement primarily in one plane, akin to a door hinge.

The integrity of the artikulationsfläche is essential for joint health. Wear and tear, injury, or disease can damage the articular cartilage, leading to pain, inflammation, and reduced mobility. Conditions like osteoarthritis are characterized by the gradual degeneration of the artikulationsfläche. Understanding the anatomy and biomechanics of the artikulationsfläche is fundamental in fields like orthopedics and physical therapy for diagnosing and treating joint disorders. The precise arrangement of these surfaces dictates the stability and function of the entire skeletal system, enabling everything from fine motor skills to powerful locomotion.
