   Introduction
 
Fusions of the lumbosacral spine continue to be a challenging area in spine surgery. The complex local anatomy, unique biomechanical forces, and poor bone quality of the sacrum are just a few of the many reasons why fusions of the lumbosacral spine have been notoriously difficult to perform.

The goals of this review were (1) to familiarize the reader with the complicated anatomy of the lumbosacral region, the specific pathological entities that involve this region, and the biomechanical forces that lead to high pseudarthrosis rates; (2) to discuss the various types of lumbosacral and spinopelvic implants and their respective advantages and disadvantages; (3) to review the most common clinical indications for lumbosacral and spinopelvic fusions; and (4) to emphasize that iliac screw placement is a safe and reproducible technique for achieving stable caudad pelvic fixation that minimizes the risk of pseudarthrosis at the lumbosacral junction.
