dislocation
Dislocation or dislocation refers to a phenomenon in which bones that form joints move away. It often occurs when excessive pressure is applied to ligaments or muscles. "Dislocation" refers to the case where the surface of the joint is not exposed to air, and "composite dislocation" when the skin above the joint is destroyed or the bone penetrates through the skin and the surface of the joint is exposed to air. In addition, depending on the cause, 'congenital dislocation' with a congenital abnormality in the joint, 'traumatic dislocation' due to external force, 'idiopathic dislocation' due to joint inflammation or tumor, 'habitual dislocation' . Simple dislocation is a physical method using a hand or an instrument. It is possible to cure the joint by fixing the bone while it is completely healed. However, joint dislocation is usually required for habitual dislocation and congenital dislocation. The most common symptom of dislocation is swelling, fever, and pain, but in severe cases nerve damage, vascular and endogenous injury may also be present.
