A protruding tailbone does not usually need to be corrected if it is developmentally related. If it is caused by trauma, it can be treated by repositioning. The tailbone is located at the lowest part of the spine, which is a non-weight-bearing area. If the tailbone protrudes due to development, it does not have much effect on the function of the spine and the surrounding organs, so it does not need to be corrected in general. If the caudal protrusion is caused by trauma, such as traumatic hip landing caused by the caudal bone fracture protrudes inward, which may compress the rectum and cause rectal dysfunction, and can be treated by manipulation or surgical repositioning. After successful repositioning the patient needs bed rest to promote fracture healing. If the symptoms of tailbone protrusion occur, it is recommended that the patient go to the hospital to improve the examination, clarify the cause of the disease and carry out regular treatment.
