Mendel T, Schenk P, Ullrich BW, et al. - This study was carried out to explore the outcome of two different stabilization techniques in bilateral fragility fractures of the sacrum (BFFS). A non-randomized, prospective study was carried out in a level 1 trauma centre. Researchers enrolled a total of 61 patients (mean age 80 years (SD 10); four male, 57 female). The per-day step count was the primary outcome parameter of functional recovery; the subjective outcome assessed by questionnaires was a secondary parameter. The results indicate that both groups exhibited significant outcome improvement and sufficient fracture healing. Although bisegmental trans sacral stablization was superior with respect to subjective outcome, both techniques can be recommended for BFFS. In addition, step-count tracking represents a reliable method to assess mobility levels.
