A joint dislocation occurs when the bones that form a joint are forced out of their normal position. This can happen due to trauma, such as a fall or an accident, and is most common in the shoulder, fingers, and knees. Symptoms often include severe pain, swelling, and an inability to move the affected joint. Treatment for a joint dislocation typically involves a healthcare professional realigning the bones, a process known as reduction. After the joint is back in place, rest, ice, and immobilization may be recommended to aid recovery. In some cases, physical therapy may be necessary to restore strength and mobility.
