Product Features

Sacroiliac Screw Type I

· Closed-end design prevents screw loosening.

· Low-profile head preserves more bone mass and minimizes soft tissue irritation.

· Lateral connector offers variable offset options, reducing the need for rod bending.

· Lateral connectors are available in various diameters to match the posterior lumbar system.

· Can be used in conjunction with S1/S2 fixation or independently, providing greater versatility. Functional even with incomplete sacrum.

Sacroiliac Screw Type II

· Wide-angle iliac screw, featuring a U-shaped opening slot. Compatible with thoracolumbar posterior systems, requiring no additional components, facilitating rod placement.

· Cannulated design enables precise screw placement into the iliac bone via guidewire positioning, ensuring surgical safety.

· Threadless shank design minimizes sacroiliac joint injury.

· Low-profile head reduces soft tissue injury.

Advantages of the S2AI Technique

· Smaller surgical exposure: Requires less tissue dissection for access.

· Easier to master: The technique has a relatively straightforward learning curve.

· Enhanced safety: Offers a safer surgical approach.

· Superior biomechanical strength: Provides strong fixation.

· Inline trajectory: Aligns directly with the cephalad (upper) pedicle screws.

· Reduced lateral tissue dissection: Minimizes the need to strip tissue outward.

· No connectors required: Eliminates the need for additional linkage devices.

· Reduced prominence at skin level: Results in a lower profile under the skin.

· Percutaneous placement capability: Screws can be inserted through small incisions using minimally invasive techniques.

· More accurate screw trajectory: Facilitates optimal screw placement positioning.
