Plan precisely – before the first anchor is set.

RotaPlan™ is a planning system for rotator cuff repair: an interactive 3D model of the shoulder, its bone built automatically from the MRI, in which you classify the tear, place anchors and rehearse the repair before surgery.

Today, the plan lives in the surgeon’s head

Rotator cuff repair is one of the most common procedures in shoulder surgery. Yet it is still planned from a subjective reading of the MRI: surgeons scroll through 2D slices and assemble a 3D picture of the tear in their head.

Surgeons read the MRI as 2D slices…

…and assemble the 3D picture in their head.

From slices to a 3D model of the bone.

And a repair plan to explore before surgery.

The real situation often only becomes clear during arthroscopy. And once the anchors are in, hindsight sets in: one more anchor, placed a little further apart, might have been the better choice.

Tear size, retraction and tissue quality all matter – but they are rarely measured in a reproducible way. To our knowledge, no commercial planning system exists for this soft-tissue reconstruction.

From MRI to repair plan in four steps

Import MRI
Load a de-identified shoulder MRI. RotaPlan checks image quality and finds the series each measurement needs.
3D model
AI builds the bone model from the MRI and drafts the rotator cuff muscles, tendon and tear where the MRI allows. The surgeon reviews every draft.
Tear analysis
Size (Cofield) and retraction (Patte) are measured from the 3D model, fatty infiltration (Goutallier) where the muscles are segmented; pattern (Burkhart) and depth you set. You confirm or override every value.
Explore & simulate
Place anchors freely on the 3D humeral head and compare constructs – then send the signed plan to PACS.

You explore, you decide – RotaPlan makes the tear visible and testable in 3D.

What the prototype does today

3D shoulder modelRotate the humeral head freely and see tendon, tear edge and footprint in space – from anterior, lateral, superior or posterior.

Standard grading, traceableCofield, Patte, Goutallier and Burkhart on one panel. Measured values come pre-filled and show where they came from; the surgeon confirms or overrides each one.

Compare constructsTwo anchor constructs side by side on the same shoulder – a double-row against a single-row repair, for example – each with its own warnings.

Medtech
An implant-agnostic planning platform – open to partnership and licensing.

Where we are

RotaPlan is a working research prototype, protected by a utility model registered with the German Patent and Trade Mark Office, and not yet a CE-marked medical device. Next, we want to validate it on real cases – together with clinical partners.
