The biomechanical advantages of bilateral lumbo-iliac fixation in unilateral comminuted sacral fractures without sacroiliac screw safe channel
BACKGROUND The aim of this study was to compare the biomechanical characteristics between bilateral and unilateral lumbo-iliac fixation in unilateral comminuted sacral fractures (USF) by finite element analysis. METHODS A 3-dimensional finite element model of unilateral sacral fractures was simulated. Three kinds of implants were instrumented into the model, including the unilateral lumbopelv...
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 کاملIliac Pedicle Wedge Graft as a New Modification for Iliac Osteotomies in Young Adolescents: A Single-blind Randomized Clinical Trial
Background: Iliac osteotomies in adolescent patients may accompany graft related difficulties such as graft absorptionand delayed union. A new modification of iliac osteotomies has been proposed to address these difficulties.Methods: A total of 24 consecutive hip joints in 21 juvenile or adolescent patients who were candidate for salter ortriple pelvic osteotomy were included....
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 کاملMinimally Invasive Placement of Iliac Screws: A Technical Note
The surgical treatment of destructive processes involving the lower lumbar spine and the sacrum often require attachment of a long hardware construct to the pelvis for improved stability. In an effort to minimize surgical morbidity and postoperative pain, and improve quicker patient mobilization, we describe a novel minimally invasive technique of percutaneously placed iliac screws. We explain ...
