Comparison Between S2-Alar-Iliac Screw Fixation and Iliac Screw Fixation in Adult Deformity Surgery: Reoperation Rates and Spinopelvic Parameters
STUDY DESIGN Retrospective cohort study. OBJECTIVE The S2-alar-iliac (S2AI) technique has been described as an alternative method for pelvic fixation in place of iliac screws (ISs) in spinal deformity surgery. The objective of this study was to analyze the impact of S2AI screws on radiographical outcomes, including spinopelvic parameters. METHODS A retrospective review of 17 patients receiv...
متن کاملUse of S2-Alar-iliac Screws Associated With Less Complications Than Iliac Screws in Adult Lumbosacropelvic Fixation.
STUDY DESIGN Retrospective comparative study. OBJECTIVE To compare clinical and radiographic outcomes between the S2-alar-iliac (S2AI) and the iliac screw (IS) techniques in the adult population and clarify the clinical strength of S2AI screws. SUMMARY OF BACKGROUND DATA S2AI screws have been described as an alternative method for lumbosacropelvic fixation in place of ISs. The S2AI techniqu...
متن کاملPercutaneous S2 alar iliac fixation for pelvic insufficiency fracture.
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 کاملFree-hand placement of iliac screws for spinopelvic fixation based on anatomical landmarks: technical note
BACKGROUND The placement of iliac screws is a biomechanically sound method for the stabilization of long multi-segment lumbar constructs. Traditional techniques for the placement of iliac screws often involve either substantial iliac muscle dissection for visualization of screw trajectory based on bony landmarks, or alternatively the use of intra-operative imaging to visualize these landmarks a...
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...
