Pubic symphysis separation

Introduction The pubic symphysis separation refers to the pubic symphysis after injury, local pain and pelvic dysfunction, X-ray, with a gap greater than 6 mm. Clinically, the pubic symphysis is painful, and there is obvious tenderness. The unilateral lower limbs cannot bear weight, the walking is weak, the lower limbs are difficult to lift, and the waist and buttocks are the main manifestations.

Cause

The disease is rarely caused by simple external force, mainly found in late pregnancy and postpartum women, especially before delivery, due to endocrine factors, the relaxation of the pubic ligament is an intrinsic factor in the occurrence of this disease. In the later stage of pregnancy, due to the weight of the fetus pressing the pelvis to cause pubic symphysis separation, or during labor, if the labor is too long, the fetus is too large, the birth is violent, the loose pubic ligament is damaged, and the postpartum pubic symphysis cannot be restored to the normal position. .

an examination

After the injury, the pubic symphysis, local pain and pelvic dysfunction, X-ray film, the gap is greater than 6 mm.

Differential diagnosis

Acute pubic symphysis separation is more common in injuries, and traumatic pubic symphysis alone is rare. The disease is mostly due to severe vaginal surgery, such as difficult forceps, vigorous traction, etc.; but there are also natural births.

1. Trauma, car accidents, etc. cause acute pelvic fractures, pubic fractures, ligament lacerations, etc.

2. During childbirth, because the fetus is too large, the productivity is good, the uterine contraction is too strong, the fetal head is suddenly decreased, such as emergency production; or the breech position is difficult, the force is too strong, the ligament laceration, pubic symphysis acute Separation.

A pelvic fracture is a serious trauma that is caused by direct violent pelvic compression. More common in traffic accidents and landslides. In wartime, it was a firearm injury. More than half of the pelvic fractures are accompanied by comorbidities or multiple injuries. The most serious is traumatic hemorrhagic shock, combined with pelvic organ injury, and a high mortality rate due to improper treatment.
