In this single-centre, prospective, non-randomised, case-controlled study (evidence level 2), the perioperative outcome results of patients with minimally invasive, stabilised BFFS (FFP4b) [Bisegmental transsacral fixation was used whenever two transsacral bone corridors at the S1 and S2 segment level could be used for fracture fixation (Fig. a and b X-ray pelvic overview (If an H-type fracture with TFC below the first sacral corpus or a sacral dysplasia was present [a and b X-ray pelvic overview (All patients were operated in prone position. Additional stabilisation of the anterior pelvic ring was consistently omitted, as the authors are of the opinion that in FFP, the ligamentary integrity is usually not impaired in a relevant manner due to the low-energy trauma.Between 2015 and 2018, a total of 124 BFFS patients were treated at our hospital. The diagnosis was usually confirmed with a pelvic radiography and computed tomography. In some cases, a contralateral sacral lesion was detected only after additional magnetic resonance imaging (MRI). Conservative treatment was initially attempted in all cases with the aim of early functional full weight-bearing under adequate pain medication WHO Level 3 for a total of 3–5 days [
