Every Monday I share a startup that I really like.
I call it the Red-Hot Innovator of the Week.
Spine navigation and robotics have largely won the accuracy argument against freehand.
The new battlefront is footprint, capital costs, vendor lock-in, workflow speed, and tactile feedback.
That focus makes OnPoint Surgical this week's pick.
Massachusetts AR startup publishes 1.1 mm / 1.3° spine accuracy—aiming to make million-dollar robots optional.

The Core Catalyst: The September 2026 Cadaver Study
OnPoint publicized a peer-reviewed study in the Journal of Spine Surgery evaluating its augmented reality (AR) platform against legacy systems.
Specimens: 5 cadavers (including osteoporotic bone with compression fractures)
Hardware: 80 pedicle screws across 3 surgeons (2 neurosurgeons, 1 orthopedic)
Technique: 25 open / 55 MIS; 34 thoracic / 46 lumbosacral; intra-op O-arm; mixed implant vendors
Key Findings:
100% radiographic accuracy: Heary I/II, Gertzbein-Robbins A/B
Zero breaches: No medial or inferior breaches (4 intentionally placed in-out-in for narrow pedicles)
Positional error: 1.1 ± 0.5 mm mean tip deviation from planned trajectory
