- Determining the amount of space between the bones in a person’s joints is a tool that doctors use when evaluating arthritis. When the space starts to narrow, it may be an early indication that someone has an arthritic condition. Joint space narrowing (JSN) is also a starting point for deciding the type of treatment to give for arthritis.

Mar 11, 2019 · At joint spaces, the surfaces of bones that rub together are covered by a layer of cartilage. Cartilage acts to soften the interactions between the two bones. But in joint diseases, such as osteoarthritis, the cartilage is worn away.
The space between the femur, or thighbone, and the tibia, or shinbone, on X-ray views represents the overall thickness of the joint cartilage surfaces of each opposing bone as they articulate, or come into contact with one another.

Apr 23, 2019 · When joint space narrowing occurs, the cartilage no longer keeps the bones a normal distance apart. This can be painful as the bones rub or put too much pressure on each other.
Oct 24, 2023 · Synovial fluid is a thick fluid with an egg-white-like consistency that lubricates and reduces friction between joints. When synovial fluid is low, which tends to happen with age, it can contribute to joint stiffness and other aging-related joint conditions like osteoarthritis.
May 15, 2024 · Most joints are movable connections between two bones. These joints are made up of the surfaces of the bones involved, a joint cavity filled with fluid, and a joint capsule. The joint surfaces (articular surfaces) of the bones are covered with a layer of cartilage.
A synovial membrane — a fluid-filled sac that lubricates and protects the joint — lines the space between the bones. This extra cushioning helps synovial joints move with as little friction as possible.
