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.
Robust Posterior Fixation
Designed to help optimize surgical results when implanting the Aspen MIS Fusion System.
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.
- 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.
- 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.
- 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.
