Abstract：Objective:To investigate the clinical effect of percutaneous internal fixation with sacroiliac joint hollow screw combined with external fixator in treatment of pelvic fracture.Methods:Forty patients with pelvis fracture admitted in the First Affiliated Hospital of Jiamusi University from Jan.2015 to Jan.2017 received percutaneous internal fixation with sacroiliac joint hollow screw combined with external fixator (internal and external fixation group),while 40 patients underwent open surgery followed by an external fixation (open surgery group) admitted in the same period were served as controls.The operation time,intraoperative blood loss,postoperative ambulation time,Majeed score,clinical efficacy and the incidence rate of postoperative complications were analyzed for the two groups.Results:The operation time and the postoperative ambulation time were significantly shorter,the intraoperative blood loss was obviously less and the Majeed score was markedly higher in the internal and external fixation group than in the open surgery group with statistical significance (P＜0.05).In the internal and external fixation group,the total efficiency rate was higher (90.0％,36/40 cases) and the incidence rate of postoperative complications was lower (7.5％,3/40 cases) than in the open surgery group (65.0％,26/40 cases and 20.0％,8/40 cases,respectively) with statistical significance (P＜0.05).The main postoperative complications were infection,osteoarthritis and deep vein thrombosis.Conclusions:Compared with the treatment of open surgery,the therapeutic effect of percutaneous internal fixation with sacroiliac joint hollow screw combined with external fixator can effectively shorten operative time,reduce the amount of intraoperative blood loss,improve the excellent rate of treatment and reduce the incidence of postoperative complications,so is worth to use in treatment of pelvic fracture.
