Vendor-Neutral vs Vendor-Locked Planning
Vendor-neutral vs vendor-locked surgical planning: what a robot-tied planner costs an implant manufacturer, and what a decoupled CT-to-plan layer gains you.
Key takeaways
For an implant manufacturer, the strategic question is not "can we plan a case" but "who owns the plan." In vendor-locked planning, the plan lives inside one company's robot or one company's implant-specific software, and the surgeon has to adopt that ecosystem to use it. If you are the manufacturer who owns that robot, this is a moat. If you are any other manufacturer, it is a wall you are on the wrong side of: the plan becomes a sales funnel for someone else's implant. Vendor-neutral planning decouples the CT-to-plan engine from the implant, so the same segmentation, alignment, CPAK phenotyping and sizing support can run against your own catalog. For a manufacturer without a robot or an in-house planner, a decoupled layer is the fastest way to offer modern digital planning without building a robotics program. Salnus builds this vendor-neutral, implant-agnostic, CT-based planning software for manufacturers to license, under a manufacturer-pays model, and it is currently Research Use Only (RUO), not a cleared device.
What "vendor-locked" costs a manufacturer
A vendor-locked planner is tied to a specific ecosystem, usually a robot or a single implant system. The planning workflow, the measurements, and often the surgical guidance only make sense inside that ecosystem. For the company that owns the ecosystem, this coupling is deliberate and valuable. For everyone else, it carries three concrete costs:
- The plan steers the implant. When planning is bundled with one vendor's implant, the plan is not a neutral clinical artifact, it is part of the sell. A surgeon who plans on a competitor's platform is being nudged toward the competitor's components. Your implant is one interface change away from being designed out of the case.
- You compete on hardware you may not have. Robotic ecosystems tie planning to a capital device. If you do not sell a robot, you are structurally behind on "digital planning" even when your implant is competitive on its own merits.
- You inherit someone else's roadmap. Depending on a rival's or a third party's locked planner means their release cadence, their supported implants, and their commercial priorities govern how your product gets planned.
The deeper point: in modern arthroplasty the plan increasingly drives which implant is used. Vendor-locked planning is how the ecosystem owner captures that leverage. If the plan is not neutral, it is working for whoever owns it.
What "vendor-neutral" means at the engine level
A vendor-neutral, implant-agnostic planner does the anatomy-and-plan work independently of the implant, then applies the selected manufacturer's component library at the end. Conceptually:
- Segment bone from CT and build a 3D model.
- Compute alignment, phenotype, rotation and sizing on the patient's anatomy.
- Fit that plan to whichever implant library is selected.
Because the first two steps are vendor-independent, the same plan can be expressed on multiple implant systems, including yours. Note the deliberate boundary: this describes the positioning, not the internals. How the segmentation and alignment logic are built is exactly the part a manufacturer licenses rather than reinvents. For a primer on the underlying idea, see how CT-based 3D pre-operative planning works.
Why a decoupled planner is strategically different
Decoupling the planner from the implant changes what the software is for. A locked planner's job is to protect one implant's share of the case. A decoupled planner's job is to plan the case correctly and then support the surgeon's implant choice, which can be your implant. That difference has strategic consequences for a manufacturer:
- You own the relationship, not the platform vendor. The plan runs against your catalog and fits into your commercial story, rather than routing the surgeon's attention through a competitor's ecosystem.
- You avoid a robotics-scale build. Robotic and locked-planner ecosystems took years and large capital programs to build. A decoupled planning layer lets a manufacturer offer AI-based preoperative planning that works with an existing implant line, without standing up a robotics division.
- You stay compatible with the surgeon's real workflow. A neutral layer fits the DICOM workflow surgeons already use and can present alignment options transparently, rather than forcing adoption of one console.
This is also the honest reason a decoupled planner is hard to find on the open market: it is strategically inconvenient for the companies best positioned to build it. Robot makers have little incentive to ship a planner that plans onto competitors' implants. That gap is precisely the space a vendor-neutral, manufacturer-licensed layer is meant to fill.
What a manufacturer without a robot or planner gains
If you make implants but do not sell a robot or an in-house planner, the practical gains from a vendor-neutral layer are direct:
- A modern digital-planning offer that works with your own catalog, without a hardware program.
- Sizing and alignment support grounded in the patient's CT anatomy, fitted to your components.
- A closed value-chain gap in markets pushing domestic production, where the implant may already be locally made but the planning software is the last imported layer. A licensed, catalog-compatible planner closes that layer.

The commercial model and the honest caveat
Salnus works with manufacturers under a manufacturer-pays structure: pilot, co-development, or white-label licensing of the vendor-neutral CT-to-plan software. The manufacturer keeps its implant relationship; Salnus provides the planning layer (segmentation, CPAK phenotyping, alignment options, sizing support); and intellectual property terms are defined by contract rather than assumed. The commercial shape can be per completed plan, an annual platform fee, or a per-surgeon license, and it is anchored to what personalization already costs in your world rather than to a surgeon's out-of-pocket willingness to pay. The details are described on the Salnus for manufacturers page.
The caveat is equally important. Vendor-neutral is a positioning and workflow choice, not a regulatory shortcut. Salnus is Research Use Only today, not a cleared device, and it makes no claim of clinical superiority or outcome improvement. Any clinical deployment requires the appropriate regulatory clearance, data governance, and validation. An OEM engagement is a pilot or co-development path toward a jointly validated product, not the purchase of a finished cleared system.
Bottom line
Vendor-locked planning concentrates the leverage of the plan in whoever owns the ecosystem, which is a moat for one manufacturer and a wall for the rest. A vendor-neutral, implant-agnostic planner decouples the plan from the implant, so a manufacturer can offer modern CT-based digital planning against its own catalog without building a robot. For a mid-size or domestic manufacturer, that is the difference between competing on digital planning and being designed out of the case. If you are evaluating how to offer modern planning without ceding the plan to a competitor, see how Salnus works with manufacturers. Salnus builds this software for manufacturers to license, as Research Use Only.
