Liigeseõõnes

Liigeseõõnes, also known as the joint cavity or synovial cavity, is the space between the articulating bones of a synovial joint. This cavity is filled with synovial fluid, a viscous substance that lubricates the joint, reduces friction, and nourishes the articular cartilage. The synovial membrane lines the joint capsule and secretes the synovial fluid.

The presence of a well-defined liigeseõõnes is a hallmark of synovial joints, which are characterized by their high degree of mobility. Examples of synovial joints include the knee, hip, shoulder, and elbow. The integrity and function of the liigeseõõnes are crucial for smooth and pain-free movement.

Conditions affecting the liigeseõõnes can lead to joint pain, stiffness, and limited mobility. Inflammation of the synovial membrane, known as synovitis, can result in an excess production of synovial fluid, leading to swelling and pain. Arthritis, a broad term for joint inflammation, often involves the liigeseõõnes and its components. In some cases, the liigeseõõnes can be accessed surgically for diagnostic or therapeutic purposes, such as arthroscopy. Understanding the structure and function of the liigeseõõnes is essential for diagnosing and treating various musculoskeletal disorders.
