Due to the irregular characteristics of the pelvic structure, the choice of internal fixation is diverse.
For patients separated symphysis pubis, a 2 or 4 holes, 4.5 or 3.5mm diameter dynamic compression plate or reconstruction plate can be used and fixed with full-thread cancellous bone screws.Another method of fixation is lag screw fixation. In patients with new sacroiliac joint dislocation with a forward approach,firm fixation can be achieved by using 2holes 3.5mm dynamic compression plates through the front of the sacroiliac joint. The posterior approach can also be used to insert 6.5mm lag screws into the sacral wings or hollow cancellous bone screws with interosseous compression for firm internal fixation. If available, the fracture may be fixed with 3.5mm or 4.5mm pelvic reconstruction plates and appropriate full-thread cancellous bone screws.
