The ringing sound of breaking the finger joints is mainly due to the anatomical characteristics of the finger joints. The finger joint is composed of the head of the joint, the socket, and two opposing articular cartilages, and the peripheral stabilizing group is only some ligaments, without strong tendons, muscles, and joint capsule protection, so the stability of the relative finger joint is not very good. Under the action of external forces, it is easy to cause a super range of motion, which will lead to rapid deformation of the surrounding ligaments, and the impact between the bones of the joint, thus producing a loud sound. The above explanation shows that breaking the finger joints with a ringing sound is damaging to the joints, and over time will cause ligamentous laxity around the joints, which will also lead to collision between the cartilage of the joints, causing damage to the cartilage, resulting in localized joint swelling, pain, and in severe cases, joint instability. When working hard, there is pain in the finger joints, so it is recommended that the action of breaking the fingers is not often performed.
