Why can finger joint dislocate swollen?

summary

Once the finger joint is dislocated, the joint deformity can be clearly seen from the appearance, and X-ray can also help the diagnosis. It should be reset as soon as possible. During reduction, the rescuer stretches the injured finger to the far end (lateral) to make the articular surface return to the joint position.

Why can finger joint dislocate swollen?

The injury of finger joint mainly includes the injury of capsule, ligament and cartilage around the joint. The figure below is a sketch of the structure of the joint and the blood vessels and nerves. When collision and other accidents occur in the movement, the joint capsule and joint ligament wrapping the joint are damaged or relaxed, leading to the joint surface sliding out of the joint, which is the formation of dislocation.

Once the finger joint is dislocated, the joint deformity can be clearly seen from the appearance, and X-ray can also help the diagnosis. It should be reset as soon as possible. During reduction, the rescuer stretches the injured finger to the far end (lateral) to make the articular surface return to the joint position.

Because dislocation is usually accompanied by tear injury of joint capsule and joint ligament, it should be fixed after reduction to obtain natural repair of joint capsule and joint ligament. The healthy finger beside the injured finger can be used as the fixed support to fix the two fingers together, and the natural flexion position can be fixed for 6 weeks.

matters needing attention

In order to prevent the occurrence of habitual dislocation, rock climbers should strengthen finger strength training to make up for joint instability caused by ligament relaxation. They can also use some support belts and finger protectors to protect their fingers. In addition, we should also pay attention to the mental attention and movement coordination, and strengthen the protection.
