In recent years numerous pedicular fixation systems have appeared, revolutionizing the technique. In 1991, the OMEGA-21 system was designed to allow the use of expansive screws in lumbosacral arthrodesis: one burst fracture, one pathologic fracture in an osteoporotic spine, one revision surgery of a vertebral fracture and one disassembly of a pedicular fixation system. In total, 11 expansive screws were placed, one of them appearing broken 15 months after implantation. Expansive screws allows the use of pedicular fixation in special situations, having two precise indications: severe osteoporosis and revision surgery.
