Radial Head Fracture 3D Model

Reproduce your patient's radial head fracture from their imaging, associated injuries included, then play the proposed fixation or replacement. They leave with their model.

How it works

In the visit, in three steps

Structured information in a few minutes, which the patient can review at home.

1
Show

Open the model and walk through the anatomy: radiocapitellar joint, radial head, capitellum, coronoid.
2
Reproduce

Set the fracture from the radiographs or CT scan: Mason type or AO/OTA code, fragment size and displacement; add the coronoid, dislocation, Osborne-Cotterill lesion or LCL tear. Then walk through the proposed treatment, step by step.
3
Share

Give the patient the QR code or an image: they find their own case, in their language.

Features

Explain in detail during the visit

Every setting updates the model live: you reproduce the fracture from your patient's imaging in front of them, then walk through the fixation or replacement you recommend.

The fracture, described in a few clicks

The “Pathology & lesions” panel describes the fracture: classification (Mason or AO/OTA), type and displacement gauges. Each setting changes the model in front of the patient.

Mason, as modified by Broberg and Morrey and by Johnston

Nondisplaced (I), displaced (II), whole head in several pieces (III); type IV is set by adding an elbow dislocation. The classification updates live, for example “Mason II · displaced,” and an explanatory card accompanies each choice.

Nondisplaced radial head fracture (Mason I): the fracture line visible, the anterolateral fragment in place. — **Mason I** · nondisplaced

Associated injuries

Four injuries can be added to the fracture, and the readout follows: coronoid fracture, elbow dislocation, Osborne-Cotterill lesion and lateral collateral ligament tear.

Associated coronoid fracture

Three fracture heights per Regan and Morrey: the tip (I), less than half (II), more than half (III). The letter B is added when the elbow is dislocated, and the Mayo “c” suffix to the fracture readout.

The treatment, step by step

Three procedures, played step by step, continuously or one step at a time. No procedure is locked: outside its usual indication (nondisplaced fracture, more than three fragments, screws alone on a detached head…), the button shows a warning that only you can see.

Headless screws

Two 2.4 mm screws, perpendicular to the fracture line, never through a fracture line, flush with the bone; one, two or three screws as you choose.

Plate

T-plate in the safe zone, three locking screws in the head, two in the neck.

After the visit

The patient leaves with their 3D model

They scan the QR code: the model, their findings and the proposed treatment follow them on their phone, in their language.

The model, exactly as you set it

At the end of the visit, the Consultation panel shows the anatomical findings, the proposed treatment and a QR code. The patient scans it and finds the model on their phone exactly as you set it, in their language.

Their fracture, and the proposed treatment to replay step by step.

Every structure explains itself on tap

Tap a fragment, a bone, a screw or the prosthesis: its name and an explanation appear.

One explanation per structure: fragments, fracture line, coronoid, Osborne-Cotterill lesion, LCL, screws, plate, prosthesis.
Written for the patient, in their language.
They can reread it on their own, on the tablet or at home.

They can replay the treatment step by step

From “The proposed treatment,” the patient replays the procedure: each step plays at their own pace, with its explanation, as often as they like.

Patient information

Quality information, documented

Only 12% of U.S. adults have proficient health literacy (National Assessment of Adult Literacy). A patient who sees their own fracture and the proposed procedure understands them, gives truly informed consent, and approaches surgery with confidence.

For the patient

They see their own fracture, reproduced from their imaging, and how the proposed treatment unfolds. They leave with the same material and can review it at home, with their family, as often as they like, before giving consent.

For the physician

Each visit created with an account keeps a record of the information provided: what was shown, when, and whether the patient reviewed it. The model image, with the anatomical findings, the proposed treatment and the QR code, downloads for the patient's chart and prints. Informed consent, as the Joint Commission puts it, is more than getting a signature.

Saved and datedThe exact state of the model: injuries shown, treatment proposed.
Identical, archivableThe patient receives what you showed; the image goes in the chart and prints.
TrackedEach time the patient opens the link is recorded.
AnonymousThe link given to the patient carries no identifying data.

“Document the informed consent conversation and the patient’s (or surrogate’s) decision in the medical record in some manner.”

AMA Code of Medical Ethics, Opinion 2.1.1, Informed Consent

The model supports the consent conversation and the written consent form; it does not replace them. Data and privacy: legal information (in French).

Questions

Questions from colleagues

Is the model free?

Yes: the fracture models are free. Treatments (fixation) and other features are paid options.

Do I need an account?

Not to open the model, set the fracture and walk through the treatment. After about fifteen adjustments, you will be asked to create a free account: it saves your visits, picks them up from one time to the next, and records when the patient opens the link.

What equipment do I need?

Just a web browser, nothing to install: computer, tablet or TV screen in the exam room; the patient opens it on their phone. One click saves an image, without the interface, for the chart.

What happens to patient data?

No patient names are stored. The link given to the patient carries only the state of the model: fracture, treatment, language and visit date. A name written on the image you hand out stays on that image.

Is it a medical device?

No: it is an educational tool. It does not diagnose, does not plan surgery, and does not replace the consent conversation or the written consent form. Among software functions that are not medical devices, the FDA lists those intended for general patient education and interactive anatomy diagrams used for training.

How long does it take in clinic?

Three adjustments and one procedure played: a few minutes, during the visit. The patient reviews it at home, as often as they like.

Can the elbow and forearm be moved?

Yes: flexion from −5° to 140°, and forearm rotation from 85° of supination to 80° of pronation. Fragments and hardware move with their bone; after the radial head replacement, a final step flexes the elbow to 30° and rotates the forearm.

Mason or AO/OTA?

Both: Mason (as modified by Broberg and Morrey and by Johnston) or AO/OTA 2R1, at the press of a button, without losing the fracture you set. The classification is recalculated from the gauges; the Mayo suffixes (c, l) and the Regan-Morrey type of the coronoid are added automatically.

Can I embed it on my website?

It is planned for upcoming plans: the model displayed on a practice or hospital website, credited to EMET Education.

Which languages?

English, Spanish, French and Russian. The patient receives the model in the language chosen during the visit, which helps with the roughly 28 million people in the U.S. with limited English proficiency, alongside a qualified interpreter, not instead of one.
