Pubic closure is not a standard descriptive term, often suggesting the presence of the following two meanings: 1. It may refer to the closure of the pubic symphysis, a part of the pubic symphysis that is itself a micro-movement joint, with fibrocartilage connections on both sides of the pubic bone and slight movement of this joint. When the pelvis is subjected to more severe compression and irritation, it can lead to joint laxity here. For example, the patient has laxity due to pregnancy, childbirth or pelvic trauma. Thereafter, a series of fixation measures, such as pelvic straps to fix the pelvis, are needed to gradually restore the pubic symphysis area to achieve closure.2. It may refer to the bony fusion of the pubic bone with other bones. When the human body is nearing the end of growth and development, the pubic bone will gradually fuse with the sit bones and iliac bones at the site of the acetabulum to form a whole hip bone. The pelvis is enclosed by the left and right hip bones, as well as the back side of the sacrum together.
