Abstract
|
|
|
|
The fixation methods that can be used for unstable posterior pelvic ring injuries have undergone many innovative changes due to the recent development of surgical and imaging techniques. After understanding the appropriate indications of first and second sacroiliac screw fixation and spinopelvic fixation, innovative methods, including the trans-sacral screw fixation, posterior tension-band plate fixation, and the S2AI screw, would be chosen and applied. Considering the anatomical complexity and proximity to the surrounding vessels and nerves in the posterior fixation, the safe zone according to the fixation options should be well understood in preoperative planning. Moreover, the functional reduction of the posterior pelvic ring through the reduction and fixation of the anterior lesion should be achieved before placing the implant to reduce the number of malposition-related complications.
