title: Surgical stabilization of postpartum symphyseal instability: two cases and a review of the literature.
abstract: During pregnancy, asymptomatic widening of the symphysis pubis by about one third is normal and considered physiological. However, peripartal relaxation of the symphyseal and sacroiliac ligaments may cause significant complaints conditions including pain and gait dysfunction. Usually, patients are treated by the application of pelvic binders and bed rest up to several weeks. Surgical stabilization is performed seldom, though it may be promising in selected patients. Based on 2 cases of postpartum symphyseal instability treated by surgical fixation, the current literature was reviewed systematically to evaluate the outcome and potential complications of surgical fixation of symphyseal instability. Thirteen articles met inclusion criteria and were analyzed in detail. Including the two cases presented, surgical stabilization of postpartum symphyseal instability has been described for 33 patients. In conclusion, though only based on case reports and case series, early surgical stabilization represents a decent treatment option for postpartum symphyseal instability and may be indicated by pain or walking disability alone. In regard to the clinical outcome comparing internal and external fixation, no differences were demonstrable. However, the rate of infection was higher in patients treated by external fixation. Based on these data, we propose a treatment algorithm for this injury.
