If a baby’s arm is swelling and has hard lumps, it could be a partial dislocation of the elbow joint. Immediate medical attention and X-ray examination are recommended.

Elbow osteitis is a sterile inflammation caused by joint damage, leading to inflammation of the periosteum, often accompanied by swelling and pain. Treatment methods include avoiding strenuous exercise, keeping the joint warm, taking non-steroidal anti-inflammatory drugs, considering acupuncture treatment and medium-frequency electrotherapy, as well as infrared ray therapy.

If a child’s elbow joint is injured, it’s unclear when the injury occurred, and there is a suspicion of dislocation. The child needs to be examined by a doctor to confirm the injury and seek treatment advice.
