Sacropelvic Fixation with S2-Alar-Iliac (S2AI) Screws Via CT-guided Navigation
نویسندگان
چکیده
Sacropelvic fixation is frequently used for the correction of complex pediatric spine deformities. S2-alar-iliac (S2AI) screws are a powerful method to obtain iliac fixation. Advantages include medialized starting point that requires less soft tissue dissection, no need connectors rod, and reduced screw head prominence. Though technique S2AI placement under free-hand fluoroscopic techniques has been described, there limited description computed tomography (CT)-guided in patients undergoing surgery spinal deformity. The goal this paper describe via CT-guided navigation compare it traditional fluoroscopy techniques.

Pelvic insufficiency fractures are fairly common in elderly patients and can be a source of major functional impairment, particularly when they involve the ilium. Early rehabilitation with adequate pain relief has been the traditional method of treatment. The recently developed S2 alar iliac technique involves placing pelvic fixation into the ilium through a pathway from the sacral ala. The bon...
متن کاملFreehand S2 Alar-Iliac Screw Placement Using K-Wire and Cannulated Screw : Technical Case Series
Objective Among the various sacropelvic fixation methods, S2 alar-iliac (S2AI) screw fixation has several advantages compared to conventional iliac wing screw. However, the placement of S2AI screw still remains a challenge. The purpose of this study was to describe a novel technique of free hand S2AI screw insertion using a K-wire and cannulated screw, and to evaluate the accuracy of the techni...

متن کاملPerpendicular Iliac Screw Placement for Reinforcement of Spinopelvic Stabilization.
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 tumor or infection. Traditional iliac fixation with iliac screws or S2 alar/iliac (S2AI) screws may provide inadequate fixation in select clinical scenarios, such as severely compromised bone quality or spino...
