Background: Pelvic fixation improves the stability of spinal instrumentation and can be used
in high-grade degenerative disease, trauma, deformity, and destabilizing invasive …

Background Fixation to the ilium is a commonly used alternative or supplement to sacral
fixation in complex spinopelvic reconstructions. This can be achieved with traditional …

Abstract Study Design Biomechanical cadaveric study. Objective To compare the
biomechanical properties of the iliac and S2-Alar-Iliac (S2AI) screw in a similar spinopelvic …

Object Long-segment spinal instrumentation ending at the sacrum places substantial
biomechanical stress on sacral screws. Iliac (pelvic) screws relieve some of this stress by …

OBJECTIVE Recent literature describing complications associated with spinopelvic fixation
with iliac screws in adult patients has been limited but has suggested high complication …

Multiple techniques of pelvic fixation exist. Distal fixation to the pelvis is crucial for spinal
deformity surgery. Fixation techniques such as transiliac bars, iliac bolts, and iliosacral …

Iliac fixation is indicated to provide spinopelvic stabilization in select cases of long segment
thoracolumbar spine fusion, spinal osteotomy/realignment, trauma, and instability caused by …

Background The placement of iliac screws is a biomechanically sound method for the
stabilization of long multi-segment lumbar constructs. Traditional techniques for the …

Objective Iliac screw fixation has been used to prevent premature loosening of sacral
fixation and to provide more rigid fixation of the sacropelvic unit. We describe our technique …

Purpose The classical spinopelvic fixation includes 1 iliac screw on each side. The purpose
of this study is to specify the indications of the “dual iliac screw”(DIS) construct, ie, when to …
