Application of minimally invasive percutaneous pedicle screw system in pelvic fractures
Abstract
Our study intends to investigate the effect of minimally invasive percutaneous pedicle screw fixation on the treatment of pelvic fractures. Sixty patients with unstable pelvic fractures diagnosed in our hospital from January 2017 to December 2018 were selected. Patients were randomly assigned into external fixation group (EF) (20 cases), open reduction and internal fixation group (ORIF) (20 cases), minimally invasive percutaneous pedicle screw system fixation group (MIPPSSF) (20 cases) followed by analysis of the operation time, intraoperative blood loss, length of incision, postoperative complications, fracture reduction and Majeed score. Compared with ORIF group, MIPPSSF group displayed significantly shortened operation time and reduced length of incision and intraoperative blood loss (P<0.05), which was worse than EF group. In MIPPSSF group, the incidence of nail infection, radial nerve injury, deep vein thrombosis, and incision infection was 5% at 2 months after operation, 40% in the EF group and 25% in ORIF group (P<0.05). The fracture reduction of the three groups was improved. The rate of Majeed scores in MIPPSSF group, EF group and ORIF group were 75%, 75% and 90%, respectively without significant differences (P>0.05). Compared with EF, MIPPSSF for pelvic fracture can reduce the incidence of postoperative complications. Compared with ORIF, MIPPSSF can reduce surgical trauma and has a high clinical value. In conclusion, MIPPSSF can reduce the postoperative complications and surgical trauma after treatment of pelvic fracture, indicating that it might be used for an approach for treating pelvic fracture.
