New Insights into Spine Surgery Technology

In a pioneering biomechanical study published in the Journal of Spine Surgery, Dr. Kingsley R. Chin, a renowned orthopedic spine surgeon and CEO of KIC Ventures, has demonstrated the exceptional strength of the InSpan® interspinous fixation device (IFD). This innovative device outperforms the traditional Aspen® implant, marking a significant advancement in spinal anatomy preservation techniques.

Study Overview

Conducted at KIC Ventures, this landmark study evaluated the performance of the InSpan® dual-locking symmetrical design against Aspen’s single-locking asymmetrical design. The research was co-authored by a diverse team of experts including Dr. Erik Spayde, Dr. William M. Costigan, and Vito Lore, utilizing advanced testing methods to assess the biomechanical properties of both devices.

The researchers adopted static pullout testing to examine the fixation strength of the implants. Results demonstrated that the InSpan® device delivered 94.8% greater resistance to pullout forces than the Aspen® model, illustrating its enhanced gripping capability and structural integrity.

Key Findings

The results of the study revealed critical insights:

• - Static Pullout Testing: InSpan® showed a remarkable increase in fixation strength, resisting nearly 95% more pullout forces than Aspen.
• - Dynamic Disassembly Testing: When subjected to disassembly tests, the InSpan® device needed over 60.7% more force than pristine Aspen devices and exhibited a staggering 400% greater resistance when used under simulated real-world conditions.
• - Failure Points: Notably, gross failure in the InSpan® design occurred at the interface with the testing material rather than the implant itself, underscoring the superior engineering of its design.

Dr. Chin emphasized the study's significance, stating, “This is the first comprehensive comparative study that solidly backs the biomechanical advantages of modern interspinous fixation designs. The findings compel us to rethink surgical strategies for spinal fixes.”

Mechanisms Behind InSpan’s Success

The InSpan® IFD features a dual-locking mechanism complemented by a symmetrical design, essential for providing secure fixation and resisting loosening under pressure. Its design was meticulously developed by a specialized team of orthopedic spine surgeons and neurosurgeons who aimed at addressing prevalent issues in outpatient spinal fusion. The device allows for interlaminar placement, helping to maintain or restore lumbar lordosis, and provides robust fixation without the use of pedicle screws. This makes it ideal for outpatient surgical centers that prioritize minimal invasiveness and quick recovery times.

Moreover, the dual-locking mechanism draws inspiration from spinal cross-links, ensuring that the device stays securely in place even under significant stress. This innovation is pivotal for adopting LESS Exposure Spine Surgery (LESS™), which merges patient safety with efficient surgical techniques, reshaping the future landscape of spine surgery.
