Comparison of percutaneous cross screw fixation versus open reduction and internal fixation for Day type II crescent fracture-dislocation: Case-control study

Abstract

Objective: To investigate the clinical outcomes of percutaneous cross screws internal fixation (PCSIF) for Day type II crescent fracture-dislocation (CFD). Methods: We reviewed 66 consecutive patients undergoing surgical treatment for Day type II CFD from June 2005 to December 2017. PCSIF was performed in 40 patients, and open reduction and internal fixation (ORIF) was performed in 26 patients. The patient characteristics, surgical complications, radiographic and clinical outcomes and were compared. Results: There was no statistically difference on the mean time from injury to surgery between the two groups. The time of operation, the amount of blood loss, the length of incision and the hospital stay were significantly shorter in the PCSIF Group. No significant difference on Matta scores and Majeed scores between the two groups. The ORIF Group resulted in a higher rate of intraoperative hemorrhage, nerve injury, discomfort and pain. Conclusion: PCSIF for Day Ⅱ type pelvic CFD was safe and effective. Minimally invasive fixation had the advantages of short operation time and hospitalization time, less intraoperative bleeding and less surgical trauma.
