Spontaneous attenuation of either the anterior oblique ligament (Beak ligament) or the dorsoradial ligament has been reported as the cause of the joint laxity, resulting in subsequent wear and tear of the articular cartilages. So far, no cause has been reported for the spontaneous attenuation of these key supporting ligaments of the TMC joint and no effective method of prevention or treatment has been reported for the early stages of the condition.
