Abstract:[Objective] To investigate the feasibility of combined conservative treatments for old pubic symphysis separation. [Methods] A retrospective study was conducted on 30 patients who received combined conservative therapies, including three–dimensional con- tinuous traction, pelvic band fixation and exercise therapy, for old postpartum pubic symphysis separation in our department from February 2018 to August 2020. The clinical and imaging consequences were evaluated. [Results] There were no obvious adverse reactions during the combined conservative treatments. Compared with those before treatment, the VAS score and SF-36 score were significantly improved at 4 weeks and 6 months after treatment (P<0.05) . At 6 months after treatment, 23 patients were marked obviously effectively, 6 cases effectively and 1 case ineffective, with total effective rate of 96.67%. Radiographically, compared with that before treatment the pubic symphysis separa- tion distance was significantly reduced at 4 weeks and 6 months after treatment (P<0.05) . [Conclusion] This combined conservative therapy, involving continuous traction for three- dimensional reduction, pelvic band fixation and exercise therapy, has a satisfactory clinical out- comes for old postpartum pubic symphysis separation with an advantage of high safety.
