Epiphyseal injuries in children can be mild or severe, and are affected differently depending on the location, extent and type of injury. Generally, mild injuries can leave no sequelae, such as slipped epiphysis. Severe epiphyseal injury will leave various sequelae, such as gradual bending of limbs, shortening of limbs, unequal length of limbs, limited extension and flexion of joints or hyperextension of joints, and pain in joints, etc. If the protruding part presses on blood vessels and nerves, it will be affected. If the protruding part compresses the blood vessel and nerve, such as elbow exostosis caused by epiphyseal injury, epicondylar fracture, elbow exostosis caused by old fracture not healing, ulnar nerve traction injury and numbness of little finger can be seen at the age of 10-20 years. Therefore, the sequelae of epiphyseal injury can not be generalized, and once it occurs, it needs to be corrected by repeated surgery, which not only increases the pain and economic burden, but also may not be completely normalized. Therefore, it is recommended to go to regular specialized hospitals in time, through the pediatric orthopedic specialist for diagnosis and treatment.
