Abstract
Aim: The present study aims to evaluate the short-term clinical effects and complications of modified three-screw fixation and conventional two-screw fixation for treating anterior pelvic ring fractures.
Methods: A retrospective study of 51 patients with type B fractures was performed. 25 patients (modified group) were treated with modified three-screw fixation and the other 26 patients (conventional group) with conventional two-screw fixation. Outcome measures included operation time, intraoperative blood loss, hospital stays, postoperative complications and the Majeed score at postoperatively 2 months, 3 months, 1 year and the time of implant removal.
Results: The mean operative times and mean blood loss for modified three-screw fixation versus conventional two-screw fixation bilateral were 54.8±10.7 min versus 32.3±9.9 min, and 153.3 mL versus 550.0 mL(p<0.001), respectively. However, the Majeed score was better in modified group at postoperatively 2 months (75.6±9.5 vs 69.7±8.3, P=0.008) and 3 months (80.3±10.7 vs. 75.1±11.9, P=0.014). No statistical difference between two groups at the time of implant removal (82.1±9.3 vs 80.9±8.8, P=0.272) and postoperatively 1 year (83.5±7.8 vs 82.6±8.2, P=0.723). No patients experienced surgical wound infection, deep vein thrombosis, delayed union or nonunion, implant loosening or rupture. 1 patient complained of tardive unilateral thigh pain at postoperatively 4 months in conventional group.
Conclusions: Both modified three-screw fixation and conventional two-screw fixation could ultimately afford satisfactory clinical and radiological outcomes with less complication for anterior pelvic ring fractures. The modified three-screw fixation might have better biomechanical strength and faster pelvic rehabilitation.
