Joint mouseA Joint Mouse (Dissekat) is a freely movable structure within a joint consisting of cartilage or bone. They are also called dissekat or free joint bodies. "Loose Body"). This structure can restrict the normal mobility of the joint – depending on its size – and cause pain. Dissekat often occurs in the context of osteochondrosis dissecans, a bone necrosis that affects joint surfaces below the articular cartilage. In an arthroscopic operation, the surgeon removes the joint body to restore normal joint function.

The Osteochondrosis is a wear-related (degenerative) disease of cartilage and bones in the area of the joints or the spine. "Osteochondrosis" means that both cartilage ("chondros") and bone ("osteo") are involved in the disease process. In principle, all joints of the human body can be affected by osteochondrosis.

Osteochondrosis occurs most frequently in the area of the spine. People with osteochondrosis suffer from severe pain in the affected joint and reduced mobility. Treatment of osteochondrosis depends on the severity and cause of the disease. If the osteochondrosis is triggered by a malposition, for example, the orthopedic specialists at the joint clinic primarily eliminate this specific cause by means of a cause-oriented (causal) therapy.

The Osteochondrosis dissecans refers to the death of small bone areas below the articular cartilage in the joint Knee. This disease occurs mostly in children. Adolescents between the ages of 5 and 20 years. Early detection. Treating osteochondrosis dissecans is important. If the disease progresses untreated, the joint cartilage is also damaged. The result can be premature joint wear (arthrosis) with chronic complaints and functional disorders of the knee joint.

Free joint body in the elbow: Osteochondrosis dissecans

A common cause of elbow pain is free joint bodies. These are small fragments of cartilage or bone that become trapped in the joint space, restricting the natural movement of the joint. The elbow joint is frequently affected by osteochondrosis dissecans compared to other joints.

There may be free joint bodies in the area of the posterior or anterior elbow joint. Some of them are located in the joint between the radius (radius) and the humerus (upper arm bone) or between the ulna (ulna) and the upper arm bone. Depending on the localization, these loose bodys then lead to restrictions in mobility when stretching or bending.

Osteochondrosis dissecans (OD) in the ankle joint is a disease of the joint surface and describes the death of limited areas between cartilage and bone in the joint. Osteochondrosis dissecans is also known medically as osteochondral lesion. In the final stage of osteochondrosis dissecans, a bone-cartilage fragment (dissekat) detaches, which can lead to painful blockage of the ankle joint (impingement in the ankle joint) and, in the long term, to ankle joint arthrosis.

Osteochondrosis dissecans of the ankle joint is a rare disease: in 75% of all cases of osteochondrosis dissecans the knee joint is affected, only 5% of all cases affect the ankle joint.

The orthopedic specialist for ankle joint diseases has various surgical options for the treatment of osteochondrosis dissecans in the ankle joint, which he weighs up individually for each patient. The choice of therapy depends primarily on the patient's age and the stage of the disease.
