This randomized prospective nonblinded study (PRESS—Prospective Randomized Evaluation of Sacral fractureS), was conducted from October 2017 to April 2020 with a parallel design at the University Medical Center Hamburg-Eppendorf. The mid-term outcomes of two different treatment options in elderly patients with sacral fractures were evaluated. Patients older than 60 years with a type B2.1 or FFP II posterior pelvic ring fracture and a fracture age of less than 3 weeks were eligible for inclusion. Patients under 60 years of age also met the inclusion criteria if they had a previously confirmed history of osteoporosis.Exclusion criteria were metastatic tumors in the pelvis, pathologic fractures, or a high-energy trauma mechanism. The diagnosis was confirmed using CT imaging. Appropriate informed consent was obtained from the patient’s or their legal guardians. The participants were randomized using a previously prepared randomization list with a random sequence of zeros and ones representing the two treatment arms of the study by a staff member at our hospital who was not involved in the study. Treatment group I received surgical treatment during the first three days after admission (ST group), while treatment group II received a comprehensive conservative treatment regime (CCT group). Data collection was planned at admission (t
