SI-LOK™ SELECT Sacroiliac Joint Fusion System
Designed for multiple approaches. Optimized for fusion.
The SI-LOK™ SELECT Sacroiliac Joint Fusion System is one of the most versatile solutions on the market for treating sacroiliac (SI) joint pain. It is the only platform with one implant that can be inserted laterally or posteriorly with freehand fluoroscopy, ExcelsiusGPS™, and ExcelsiusHub™. SI-LOK™ SELECT is designed to provide surgeons with the necessary tools to perform SI fusions using their preferred technique.
Versatile Placement
- Optional polyaxial washer is designed to minimize prominence while maximizing angulation (±15°) to contour to patient anatomy
- Washerless implant options allow for low-profile or no-profile (if recessed) placement
True Fusion
- Overlapping slot geometry is engineered to optimize fusion across the SI joint and accommodates varying patient anatomy
- Slots accept allograft or autogenous bone graft
SintrOS™ Surface Technology
- Laser surface treatment is designed to encourage cellular activity at the bone interface
Enabling Technology Compatible
- Compatible with freehand fluoroscopy, ExcelsiusGPS™, and ExcelsiusHub™
- Robotic technologies such as ExcelsiusGPS™ allow advanced screw trajectory planning and accurate placement for multi-planar fixation
