The inclusion criteria are:

1. Patient 60 years of age or older.
2. Low energy injury mechanism.
3. LC1 pelvis fracture (AO/OTA 61B1.1,61B2.1, or 61B3.2) confirmed with antero-posterior, inlet, and outlet pelvis radiographs, computed tomography, or magnetic resonance imaging.

8. Patient is too ill, in the judgement of the attending surgeon, for nonoperative care.
9. Problems, in the judgment of study personnel, with maintaining follow-up with the patient.
10. Expected injury survival of less than 12 months.
