Postpartum widening of the hip bone refers to the change in the shape of the pelvic ring when the pelvic cavity increases in size due to the baby entering the pelvis, separating the pubic symphysis in the front and the sacroiliac joints in the back. Theoretically, the pelvic ring cannot be restored because the entire pelvic bone structure has changed. However, women with postpartum anterior pubic symphysis pain and posterior sacroiliac joint pain can be treated using traditional Chinese medicine techniques that can relieve the pain. For example, the Guiyuan Tapping Method in the Palace Bone-setting Technique treats postpartum pubic symphysis joint separation pain. In some people, the pubic symphysis joint gap will shrink from 3-4cm to 1-2cm through several manipulative repositioning treatments, which can be very therapeutic.
