Free-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 ...
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 کاملThe flying buttress construct for posterior spinopelvic fixation: a technical note
BACKGROUND Posterior fusion of the spine to the pelvis in paediatric and adult spinal deformity is still challenging. Especially assembling of the posterior rod construct to the iliac screw is considered technically difficult. A variety of spinopelvic fixation techniques have been developed. However, extreme bending of the longitudinal rods or the use of 90-degree lateral offset connectors prov...
