The Aspen System is a complete portfolio of spinous process fixation devices that offers a less invasive alternative to pedicle screws and facilitates interbody and posterior fusions.
Aspen® MIS Fusion System
Robust Posterior Fixation
Designed to help optimize surgical results when implanting the Aspen MIS Fusion System.
System Features
The Aspen MIS Fusion System consists of a family of spinous process fixation devices designed for rigid, posterior fixation to promote fusion from T1 to S1.
Proven Efficacy
- A randomized, controlled, multi-center clinical trial showed that the Aspen System could be a significantly faster and less invasive alternative to pedicle screw fixation in support of interbody fusion1.
- Biomechanical testing has demonstrated comparable stability of the Aspen System to pedicle screw fixation in support of both TLIF and ALIF3,4.
Versatile Design
- Spiked-plate design provides reliable bony fixation under both static and fatigue loading conditions.
- The Z-shape of the Aspen implant allows it to contour to patient anatomy.
- Integrated load sharing central barrel can retain 0.5cc to 3.0cc of bone graft material.
Comprehensive Offering
- Includes a flared plate option with 45° angle at one end for anatomical fit for L5–S1.
- Small footprint ensures easy positioning for varying patient anatomy from T1–S1.
- Offset plate allows for optimal placement in the strongest bone of the spinous process.
