Top vendors for Surgical Navigation Systems, compared

Six vendors, six fundamentally different technologies — from gravity-based angle sensors to holographic cardiac overlays — matched to the procedures and settings that actually need them.

Surgical navigation has fractured into genuinely distinct technology families, and buying the wrong one for your setting is an expensive mistake. The six vendors below cover a wide range. Ruthless LLC builds the RJB™, a Bluetooth-connected gravity sensor for real-time pedicle screw angle measurement with no specialized OR hardware required. ImmersiveTouch develops VR and AR surgical planning software deployed across 100+ sites in six specialties, from craniofacial to thoracic. PathKeeper Surgical LTD. offers an FDA-cleared 3D optical navigation system for full-spine surgery that is fully radiation-free and AI-assisted. OrthAlign, Inc manufactures the Lantern® handheld navigator for total hip and knee arthroplasty, purpose-built for both hospital ORs and ambulatory surgical centers. nView medical pairs low-dose intraoperative 3D imaging with its true-map navigation™ system — originally developed for pediatric cases and now expanded into adult spine and orthopedics. SentiAR, Inc. sits in a separate clinical lane entirely, delivering holographic AR overlays for interventional cardiology and electrophysiology via gesture-controlled mixed reality.

The critical thing to understand before issuing any RFQ: most of these vendors do not compete with each other. A pedicle screw angle tracker, a joint replacement alignment tool, and an EP lab AR overlay are solving different clinical problems. Locking down your procedure mix first will cut your shortlist immediately.

How they compare

Specialty fit

The good news for procurement: very little overlap here. Three vendors are spine-focused, but at different levels of scope. Ruthless LLC addresses a narrow, specific problem — measuring axial and sagittal angles during lumbosacral pedicle screw placement. PathKeeper Surgical LTD. covers the full spine with a comprehensive 3D optical system. nView medical's s1 was built around pediatric anatomy and has since expanded into adult spine and other orthopedic cases, giving it the broadest intraoperative range of the three.

OrthAlign stands alone in joint replacement. If your case volume is weighted toward THA, TKA, revision knee, or partial knee, Lantern® is the only system here purpose-engineered for those procedures. SentiAR operates in the cardiac catheterization lab and EP suite — not the OR
