Product Overview
The VIPER® Sacral-Alar-Iliac Screw is the first implant designed specifically for the Sacral-Alar-Iliac technique for sacropelvic fixation. Fusions of the lumbosacral spine continue to be a challenging area in spine surgery. The complex local anatomy and unique biomechanical forces are just a few of the many reasons why fusions of the lumbosacral spine have been notoriously difficult to perform.
There exists various types of lumbosacral and sacropelvic fixation implants and techniques, all having their respective advantages and disadvantages. The Sacral-Alar-Iliac technique evolved out of these techniques. Its method of screw placement is a reproducible technique for achieving stable pelvic fixation that minimizes the risk of pseudarthrosis at the lumbosacral junction.
