[Trends in indications and technique of osteosynthesis. Innovations in surgery of the spine].

More understanding of the biomechanics of injured segments, standardized dorsal and ventral accesses to all spinal column levels, and developments in fixation systems specifically conceived for the stabilization of vertebral column lesions have all greatly expanded the operative indications for spinal column injuries. Modern fixation systems should have the following features: short-term application, angular stability, universal suitability for all types of fractures, ability to bear axial loads, thus dispensing with the need for additional external stabilization.
