Unstable pelvic ring fractures are challenging injuries regarding their reduction and stabilization. The presented study evaluates the results of a minimally invasive and quick one-stage stabilization ofsacral fractures combined with bilateral pubic rami fractures during a period of national limited resources and decreased general security aiming at reduction of the duration of hospital stay and overall costs. Sixteen patients with unilateral sacral fractures and bilateral pubic rami fractures without lumbosacral dissociation were fixed by two retrosacral threaded transiliac rods and an anterior external fixator. Results were assessed with Majeed score and Matta-Tornetta radiologic criteria for post-operative reduction. The follow up period averaged 23 months. There were 9 cases excellent, 4 cases good and 3 cases fair. The duration of surgery and the number of intra-operative X-ray images were recorded. The presented technique is simple, reproducible and quick for one-stage fixation of the unstable pelvic bony disruption. It reduces the operative time, radiation exposure, duration of hospital stays and cost of care during a critical national period with limited resources.
