When external forces or pathological damage cause the bones that form a joint to move out of their original position, resulting in the loss of normal function, it is called joint dislocation or dislocation disease.

bubble_chart Diagnosis

1) Dislocation: Local swelling, pain, and dysfunction of the joint.

2) Deformity: Different joint dislocations produce different deformities. For example, shoulder dislocation results in a "square shoulder" appearance.

3) Hollow sensation at the normal joint site: In superficially located joints, palpation may reveal an empty feeling at the joint, while the dislocated joint can be felt nearby.

4) Elastic fixation: After dislocation, the joint may remain in a peculiar deformed position due to reflexive muscle spasms around it, exhibiting elastic fixation. {|103|}

bubble_chart Treatment Measures

1）First aid: For a suspected dislocation, the injured should be examined and given first aid on the spot. Pay attention to signs of shock, promptly bandage the wound, and provide temporary immobilization to avoid repeated injury.

2）Reduction: Under conditions of pain relief and absence of muscular rigidity, use gentle manipulation to reduce the joint.

3）Immobilization: After reducing the dislocated joint, necessary immobilization should be applied to allow the joint capsule and surrounding soft tissues to heal quickly and prevent habitual dislocation.

4）Functional exercise: All unfixed joints and the entire body should undergo exercise to promote blood circulation and prevent joint adhesion and stiffness. After immobilization is removed, the dislocated joint should also be actively exercised.
