The treatment for this type of epiphyseal separation belongs to one of the subtypes of epiphyseal injury. For this type of patient, the treatment can be done by repositioning the epiphysis manually, placing the affected side in a cast or brace, and then sending the patient to the radiology department to take radiographs of the affected side to assess the effect of repositioning the epiphyseal separation manually. If it is confirmed that the epiphyseal separation has been completely repositioned or is completely fit together, the patient can continue to be immobilized in a cast or brace. The duration of fixation is about 4-6 weeks, and the radiographs need to be reviewed periodically during the fixation period. After 4-6 weeks, the radiographs will be reviewed for the last time, and if good healing is confirmed, the cast or brace can be removed and the patient’s limb can be functionally exercised. If the radiographs show that the epiphyseal separation is not well repositioned, surgical repositioning can be performed, and after the epiphysis and epiphysis are satisfactorily repositioned after incision, the epiphysis and epiphysis are fixed with a gristle pin, and after surgery, the patient is again fixed with a cast or brace.
