Caudal protrusion can be divided into congenital and acquired, the caudal protrusion caused by congenital factors does not need to be corrected, and the caudal protrusion caused by acquired factors can be considered for conservative treatment or surgical correction. If the herniated tailbone is congenital, it is not accompanied by pain and other symptoms, and has no effect on the patient’s work and life, so it does not need to be treated or corrected. If the herniated coccyx is caused by acquired factors, commonly caused by trauma to the coccyx fracture dislocation, conservative treatment can be taken, local topical application of diclofenac diethylamine cream or oral nimesulide anti-inflammatory pain, if the symptoms are difficult to alleviate, the feasibility of coccygectomy to be corrected. If the symptoms are difficult to be relieved, coccygectomy can be performed to correct the problem. Normally, you should pay attention to the protection of the tailbone to avoid impact, pressure or friction on the tailbone.
