Ms. Zhao called to ask: I accidentally slipped while taking a shower and sat down on the floor with severe pain. Later, I went to the hospital for examination and the X-ray showed that my tailbone was dislocated. After a week of treatment with internal and external medication, the pain symptoms did not improve significantly and I still felt severe pain when sitting. How to treat the dislocation of tailbone? Doctor’s answer: The human tailbone consists of 4-5 healed segments, which metamorphose from the tail of mammals, and its base corresponds to the sacral vertebrae to form the sacrococcygeal union. When normal, the coccyx is basically inactive or has only slight back and forth movement. When the human body sits and falls, the tailbone is easily injured. After the tailbone is injured, if there is no fracture or serious dislocation, rest, physical therapy, hot compresses and manipulation are usually the options. If the swelling is obvious, the person can take oral or local topical medicines to promote blood circulation, reduce swelling and pain, and then carry out manipulation treatment after the swelling subsides. Manipulative therapy includes the following: First, the patient lies on the bed, the doctor uses the thumb to press the Changqiang point, and pinch and rub the Renzhong point for two minutes, then press the palm of the hand on the sacrococcygeal area, and press and rub it for three minutes, and then move the palm of the hand slightly upward, so that the edge of the palm of the hand is in the sacrococcygeal area. While continuing to press and knead, the patient coughs vigorously to increase abdominal pressure, which has the effect of mild massage and promoting reset. Secondly, if the dislocation is obvious, intra-anal reset is required. That is, the doctor will be the middle finger or food into the anus, hook pull tailbone to the dorsal side, in order to restore its normal position. For unmarried female patients with severe dislocation, it must be reset to avoid affecting labor and delivery in the future. If manipulation fails to reset the tailbone, resection of the tailbone may be considered. After reset, rest and position should still be paid attention to within two weeks, and sitting and sit-up should not be allowed to avoid recurrence.
