What is a joint dislocation?

A joint dislocation is an acute mechanical injury that occurs when an external force—such as a fall, car accident, or sports injury—causes the ends of the bones forming the joint to move out of their correct anatomical position [1]. When the bone is displaced, the joint completely loses its stability and its motor function is disrupted, requiring urgent medical intervention [2]. Dislocation can occur in various joints in the body, ranging from large joints like the shoulder, which is the most common site of injury, to the hip, knee, elbow, and even small joints like fingers and the thumb [1] [2].

How do you recognize the symptoms of a joint dislocation?

Symptoms of a joint dislocation appear suddenly and clearly, and are often sufficient evidence that immediate medical attention is required. The most common signs include:

• Noticeable deformity in the shape of the joint, where it appears out of its natural alignment or uneven [1] [2].
• Acute and intense pain concentrated directly in the affected area at the time of injury [2].
• Severe and rapid swelling around the joint area, reflecting internal bleeding or an immediate inflammatory response [2].
• Loss of movement, where it is difficult or impossible for the injured person to move or bend the affected joint due to bone displacement [1] [2].

First aid rules when a joint dislocation is suspected

Once a joint dislocation is suspected, the condition must be handled with extreme caution to avoid exacerbating the damage. Follow these steps as first aid measures until you reach the hospital:

• Seek medical help immediately: A joint dislocation is an emergency, and obtaining specialized help should not be delayed [1] [2].
• Avoid moving the joint: Keep the joint in its current position as much as possible. It is recommended to use a splint or immobilization device to prevent any additional movement that could worsen the condition [2].
• Use ice: Apply ice packs to the injured joint to help reduce swelling and control internal bleeding, taking care not to press firmly on the area [2].

Risks of attempting self-reduction of the joint

It is extremely dangerous for a non-specialist or the injured person themselves to attempt to put the joint back into place (joint reduction). Such attempts may lead to torn ligaments or damage to the nerves and blood vessels surrounding the joint [2]. An accurate medical diagnosis, which often requires an X-ray, is essential to ensure the bones are returned to their correct position safely and with minimal complications [1]. Treatment after reduction depends on the type of joint and the severity of the injury, and may include pain medication, immobilization for a period of time, or rehabilitation programs to ensure the restoration of normal joint function within weeks [1].
