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

摘要

A diagram for the process of fracture reduction and fixation. a Pelvic Day type II crescent fracture-dislocation. b A 5-mm Schanz nail was inserted into the ilium to correct the rotational displacement. c A the top rod was used to correct the separation displacement. d Percutaneous insertion of guide pin to fix the sacroiliac joint. e Another guide pin was inserted 15° outwardly in the transverse plane and 30° downwardly in the sagittal plane to fix the iliac fracture. f Screwed the hollow compression screws with a diameter of 6.5 mm or 7.3 mm along the guide pin
