After the baby changed clothes, he refused to lift his little arm, cried a lot when he moved, went to the hospital to take X-rays, and could not see any problems. Zheng Guangliang, president of Xiamen Guangliang Orthopaedic Hospital, said that if the child has such a performance, it should be considered whether there is a subluxation of the small head of the radius in children. Radial microcephalic subluxation, also known as pulling elbow, is one of the common elbow injuries in infants and young children, and the age of onset is mostly 1 to 4 years old. The small head of the radius is fixed by the crinular ligament on the side of the ulna coronal process, and the annular ligament of children is not as strong as that of adults, so when the elbow joint is straightened and the forearm is suddenly pulled longitudinally, it will cause a subluxation of the small head of the radius. The following conditions are most likely to cause subluxation of the radius head, so parents must be careful. (1) Pull the baby's hand to walk, the baby suddenly falls or goes up and down the steps, the parents violently lift the baby's forearm; (2) when wearing clothes, the baby's forearm is pulled by the cuff; (3) when rolling on the bed, the body presses the upper limbs under the body, forcing the elbow joint to overextend. How to judge the subluxation of the small head of the radius? (1) The disease is mostly caused by indirect violence, such as the above situation. (2) The baby is reluctant to lift the affected limb after being injured, and the forearm cannot be rotated backward. (3) The elbow joint (in the extension) is mostly in the mild flexion position and the forearm rotation before the drooping position. (4) There is no swelling and deformity in the elbow joint, but there is obvious tenderness at the small head of the radius. (5) There is no abnormality in the X-ray. The cause of the dislocation is clear, how to prevent it? 1. When usually pulling (lifting) children's hands or wearing clothes, the hand should be avoided in the anterior position of the hand, and the sleeves should be pulled at the same time. 2. Prevent falling. 3. Adults and children should pay attention to the method when playing, and cannot hold (lift) hands alone. 4. Avoid repeated dislocations to prevent habitual dislocations. Zheng Guangliang said that once it is found that children before the age of 5 have a history of forearm traction (no trauma and falls), children who touch the affected limb cry and cry, and the affected limb is limited in movement and cannot be lifted, it is best to find a specialist doctor for diagnosis and treatment to prevent misdiagnosis and mistreatment.
