Stabilizing the lower spine can be challenging, especially in patients with
spinal deformities, severe scoliosis, or complex degenerative changes. At IGEA
Brain, Spine, Pain & Orthopedics, we use Sacral Alar Iliac (SAI) screws to
anchor the very base of the spine, providing durable stability and improving
surgical outcomes.
What Are SAI Screws?
SAI screws are specialized screws inserted through the sacrum and into the
iliac bones of the pelvis. They provide a strong, low-profile anchor for
spinal fusion procedures, particularly when long fusions extend to the sacrum.
Why SAI Screws Are Important
-
Enhanced Stability: By securing the spine to the pelvis, SAI screws reduce
the risk of implant loosening or failure.
-
Low Profile Design: Compared to traditional iliac screws, SAI screws sit
deeper and cause less soft tissue irritation.
-
Ideal for Complex Deformities: Effective in long fusion constructs, severe
scoliosis, spondylolisthesis, or revision surgeries.
How the Procedure Works
-
Pre-Surgical Planning: Advanced imaging helps determine optimal screw
trajectory and size.
-
Minimally Invasive or Open Placement: Screws are carefully inserted through
the sacral alar into the iliac bones.
-
Fusion and Instrumentation: SAI screws anchor rods and other instrumentation
to stabilize the spine and promote fusion.
Benefits of SAI Screw Stabilization
- Strong fixation for complex spinal reconstructions
-
Reduced risk of screw loosening or pelvic pain compared to traditional
techniques
- Enables long-term correction of deformities and improved alignment
- Supports earlier mobility and recovery after surgery
Who May Benefit from SAI Screws
- Patients with long spinal fusion constructs extending to the sacrum
-
Severe spinal deformities or scoliosis requiring robust pelvic fixation
- Revision surgeries where previous instrumentation failed
- Complex degenerative conditions affecting spinal stability
