Validated
Biomechanics.
We generate independent biomechanical evidence, validated across all four domains, from in-silico models to in-vivo results. The proof regulators, clinicians, and device makers trust across a device's lifecycle.
Biomechanical evidence, generated and validated.
We produce biomechanical data across the musculoskeletal system and every specialty our published work reaches. Every result across the four domains is validated and produced in accordance with ISO/IEC 17025.
Sequence · — — — Cross-validation
Validate once. Iterate forever.
We build computational models, digital twins of physical models, and validate them against physical ground truth: in-vitro, in-situ, or in-vivo, depending on the experiment. Many are already validated and ready to run, and we build custom validated models to order. Once a model is validated, testing the next design, technique, or anatomy is computation, not another study. Send us a device and imaging, and we return results.

Repeatable, at any volume.
Standardized non-cadaveric testing on synthetic bone, metal, and other analogs gives high-volume, repeatable mechanical evaluation, plus usability and surgical-training labs. It's validated against in-situ and in-vivo evidence, so synthetic results map to real tissue and real patients.

Ground truth, in tissue.
Human cadaveric biomechanics is the highest-fidelity physical model, and where surgical-technique and usability work happens in real tissue. It's validated against in-vivo evidence and grounds it in turn: cadaveric and clinical results check one another.

Proof, in living patients.
Biomechanical validation in living patients is the ultimate ground truth. It spans motion and kinematics, load and stress transfer, fixation and migration, fusion, alignment, and the full range of how a device behaves in the body, measured from clinical imaging and follow-up. In-vivo evidence is what the other three domains are ultimately checked against.
Start a projectEvidence that answers only to the data.
That's why regulatory bodies, peer reviewers, clinicians, device manufacturers, and investors all rely on our findings. Everyone across a device's lifecycle needs the biomechanics to hold up. And it's why your design stays entirely yours: no outside institution shapes a result, claims your IP, or stands between you and the work.
Evidence for every decision.
The same evidence supports decisions from first design through post-market. One source, across the device lifecycle.
Peer-reviewed, and presented widely.
Spine, joint reconstruction, sports medicine, and trauma: independent biomechanical evidence across orthopedic specialties, from cadaveric and computational studies through clinical results. Peer-reviewed, and presented at the field's major meetings.
The engineers behind the work.
A team of engineers and scientists generating independent biomechanical evidence, led by its founders, Jeremi Leasure and Richard Raji, whose backgrounds span computational and physical biomechanics.
