In daily life, many people fail to perform proper warm-up exercises before exercising, which can easily lead to arm dislocation. When the arm is dislocated, it can be extremely painful, and the dislocated arm may not be able to lift normally, with a concave appearance at the dislocated site, allowing direct observation of the changes in arm dislocation. If you encounter someone with a dislocated arm, they should stop exercising immediately and seek medical attention for bone setting, as failure to do so may result in uneven arm lengths once the dislocation heals.

Methods for Determining and Handling Arm Dislocation

1. Activity Arm Test: Place a toy in front of a child and ask them to reach out and grab it. If they avoid using a particular arm or are unable to raise it, this may indicate a dislocation.

2. Observing Arm Joints: If a child experiences arm dislocation, they should seek medical attention immediately for reduction by a specialist. It is best to restore the joint to its original position within 2-3 hours after dislocation, as prolonged delay can lead to swelling of surrounding tissues and make reduction more difficult. Additionally, the dislocated joint can compress nerves, and stretched ligaments and muscles can cause pain with movement. Parents can use a large scarf folded into a triangle to sling the arm around the neck, but should avoid moving the affected limb to prevent further injury.

3. Joint Reduction and Post-Reduction Care: After joint reduction, fixation is generally not required. However, dislocations can be recurrent and habitual, so parents should avoid using rough methods to suddenly pull on the child's arm, which can lead to re-dislocation and the formation of habitual dislocations. Additionally, when dressing or undressing after successful reduction, it is important to follow the correct order: dressing should start with the dislocated side first, followed by the other side, and undressing should begin with the healthy side, followed by the dislocated side, to avoid causing further dislocation.

4. Joint Pain: The patient may experience severe pain in the joint, followed by a loss of normal joint function. Additionally, there may be deformities in the joint position. Arm dislocations can be classified into several types, including traumatic dislocation, congenital dislocation, and pathological dislocation. After arm dislocation, the patient's joint capsule, ligaments, articular cartilage, and muscles may also be injured. Nearby joints may also experience swelling and hematoma. If reduction is not timely, hematoma organization and joint adhesions can lead to varying degrees of functional loss in the joint.
