Spinopelvic injuries result from high energy trauma with overloading through the sacrum. These lesions can accomplish either bone fractures, ligament injuries or, most commonly, both. They may be accompanied with other associated life threatening injuries and cause biomechanical instability with potential fracture non-union, mal-union and subsequent lifetime pain and disability. Surgical stabilization of spinopelvic injuries requires planning in order to apply the appropriate osteosynthesis principles (compression; neutralization; buttressing and tension band).In general terms simple sacral fractures can be treated under compression by iliosacral screws. However, as more complex ones cannot be compressed, they need vertical support and neutralization of shearing forces (neutralization and buttressing principles). For that purpose, spinopelvic instrumentations appear to be the current appropriate technique of stabilization. In the herein paper the general principles of sacral fracture osteosynthesis are discussed, as well as its application to spinopelvic injuries. Controversies on positioning, surgical approach, per-operative traction, sacral laminectomy, type of biomechanical construct, length of fixation, screws length, mode of weight bearing, and osteosynthesis hardware removal are discussed.
