Table 1 Preferred fixation choices for posterior pelvic ring injuries. For dysplastic sacra with recessed sacral ala, etc., the authors attempt an S1 screw but may also place an S2 screw
From: Trans-sacral screw fixation of posterior pelvic ring injuries: review and expert opinion
Unilateral sacral ala fracture, vertical, complete | No fixation |
Unilateral, vertical, complete, minimally displaced | 1 trans-sacral screw + 1 iliosacral screw/trans-sacral screw |
Unilateral, vertical, complete sacral fracture, displaced | Posterior tension band plate + 1 trans-sacral screw |
Sacro-iliac joint dislocation | 1 iliosacral screw |
Sacro-iliac fracture joint dislocation | Innominate bone reduction and fixation + 1 TSS |
Bilateral, vertical sacral fracture | 2 TSS from opposite directions |
Pelvic malunion/nonunions | Posterior tension band plate + 1 or more TSS |
