Freehand 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...
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 ...
متن کاملStrategy for salvage pedicle screw placement: A technical note
BACKGROUND Salvage surgery for failed lumbar spine fusion with a loosened pedicle screw is challenging. In general, the strategy includes replacement with larger and longer pedicle screws, augmentation with polymethylmethacrylate cement or hydroxyapatite granules, and extension of fused segments. The purpose of this study is to introduce a new technique for pedicle screw replacement after faile...
متن کاملThoracic pedicle screw placement: free-hand technique.
Thoracic pedicle screws provide a number of advantages over other methods of spinal fixation in treating a variety of conditions including: better pull-out strength and greater control in the sagittal, coronal and rotational planes due to increased stability to axial, bending and rotational forces by three-column fixation, fewer vertebral motion segments arthrodesed, no or lessened need for pos...
