Lumbopelvic fixation remains a challenging and controversial topic because of the high mechanical demand around this area, high nonunion rate of lumbosacral junction and the invasive nature of the procedures. The indications for lumbopelvic fixation includes deformity, degenerative pathology, neoplasms, trauma, flat-back syndrome, pelvic obliquity, high-grade spondylolisthesis and infection in the lumbosacropelvic spine (1). There are multiple techniques exist for lumbopelvic fixation, including trans-iliac bars, iliac bolts and sacroiliac screws. With the advent of iliac screws in the early 2000s, several study reported improved outcomes compared with the Galveston technique. Iliac screws can offer better pull-out strength than the earlier Galveston technique and easier placement of modular components in lieu of complicated 3-dimensional contouring of rod (2,3).
