First, navigate to the “Cases” section and click on “New Case.” In the case info area, you’ll see fields to enter details for the case, patient, history, and surgery. Fill out all the relevant information comprehensively, especially if you plan to share this case. Whether you’re referring the case with a surgeon, or the surgeon yourself, providing detailed information is key to effective collaboration.

Once you’ve entered the details, it’s time to add the images. Click the ‘Images upload’ button to upload diagnostic images from your computer. You can select multiple files at once, saving you time, or drag and drop images into VPOP. Feel free to add radiographs, DICOMs, or any other relevant images. VPOP will automatically complete case info from metadata in DICOM images.

Add any relevant PDF files, such as lab results and reports.

You can reorder the images as you like, and duplicate or delete them as needed.

You can add images and case info at any time and in any order that suits your workflow best.

After your images are uploaded, you’ll need to calibrate them to ensure all your measurements are precise. Most DICOM images will be calibrated automatically, but for other images, we need to calibrate them manually.

From the ‘Images’ tab on the right-hand side menu, select “Image,” then click ‘Calibrate.’ Choose the type and scale of your marker, and use the line tool to measure the marker in the image. Accuracy here is crucial.

Okay, VPOP saves all your changes automatically.

Did you know you can also email cases directly to your VPOP inbox? This feature makes it easy to forward case emails to your VPOP account, especially when you’re not at your desk. Find your unique VPOP Inbox email address on the profile page. By the way this Inbox email address is not the same as your username.

Start by opening your email client and compose a new message. Address it to your unique VPOP inbox email. Then, attach any relevant images or documents—such as radiographs, DICOM files, or PDFs with patient information. Remember to keep this email address safe and only share it with trusted people.

Add any necessary notes in the body of the email for context and hit send.

Once you send the email, it will automatically create a new case in your VPOP account. Simply switch back to VPOP, where you will see a notification of the incoming case. Click “Import,” then choose to create a new case or add to an existing one.

Click on the menu button on the right-hand side of the case view and select the “Implants” tab. Here, you can filter the entire library by brand and type, making it easy to find the exact implant you need for your plan.

You can move the implant around as if it were sitting on your desk. Pushing one end will allow it to slide around with some rotation, while pushing directly in the middle ensures movement without any rotation.

On the iPad, simulate the action with two fingers as if the implant was actually on your screen, allowing for intuitive and precise adjustments.

To rotate the implant, simply grab the rotation handle. The further you drag, the finer the control you have over the rotation.

The implant palette will display the selected implant’s details. Here, you can choose a different size from the same family or select the left or right version if available.

Here, you can choose a different size from the same family or select the left or right version if available.

Adjust your view of the implant by clicking the arrows to change its orientation.

To remove the implant, click the delete button or press the delete key on your keyboard.

Now you’re familiar with the basics of managing implants in VPOP. Additionally, you can adjust the implant’s opacity and toggle the visibility of the implant code to better suit your viewing preferences.

But that’s for another video!

Navigate to the right-hand menu in the case view and select the ‘Tools’ tab. Then, select ‘Measure’.

“VPOP” allows you to measure diameter, circumference, radius, and length. You can toggle the measurement value off if helpful and lock the line axis to avoid any inadvertent movement.

To superimpose a circle, select ‘Radius’ and move to meet the circumference of your anatomical landmark. Now move the circle centre to achieve the best fit.

To measure an angle, define one axis, then add another line. At any intersection, VPOP will automatically display the angle quadrants.

If we click on an axis, and then the angle, we can see the quadrants and select the one of interest.

You can also track a landmark or axis shift by clicking on one end to follow the area of interest with your intersection.

To define a freeform area of bone you wish to move, you’ll need the reposition tool.

Open the menu at the top right, then choose “Tools” and select “Reposition Tool.”

Position your starting point and click “Start Drawing.”

Now, lassoo the anatomical area of interest. You don’t have to join the ends; VPOP will automatically connect them with a straight line. This feature can also be used to mimic a linear osteotomy in the plane of the image.

Click “Done” when ready.

To pan, rotate, and reposition the fragment, simply use the on-screen controls. VPOP will track any rotation you make.

Navigate to the right-hand menu in the case view and select the ‘Tools’ tab. Then, select ‘Anatomic Axis’.

The Anatomic Axis tool allows you to define a centered axis within a length of bone by positioning two circles whose circumferences meet the cortices on either side in any given radiographic projection.

First, choose the positions of these circles. There are two defaults for your convenience: for a proximal or distal Anatomic Axis, you’ll need the 25th and 50th percentiles. For other planning requirements, you may need the 33rd and 66th percentiles. You can customize this to suit your specific planning needs for your patient.

Let’s span the length of the bone. Now, choose one of the circles to centre it in the bone. You’ll notice how they helpfully rotate around their neighbouring circle. Place the far edge on a cortex, and then expand the circle on the adjustable side to span the cortices.

Do the same for the other circle. Place the far side on a cortex, then expand the green circle on the adjustable side. You have now defined your centered Anatomic Axis.

Now, delineate the fragment you wish to move. If you define a proximal portion, you can rotate to a target joint orientation line.

Alternatively, you can delineate a distal portion and rotate to a target mechanical axis to suit your planning style.

Your rotation is noted in degrees, circumferential travel, and the all-important chord rotation.

Navigate to the right-hand menu in the case view and select the ‘Tools’ tab. Then, select the ‘Wedge Tool’. Your wedge will be displayed with an angle, a wedge base height, and a green line for delineation.

You can pan the wedge, move each corner, and rotate the wedge. Once positioned, you can start your cut. The wedge has a green line from which to delineate.

Click ‘Done’ when you’re ready, and you’ll see the proximal fragment reduce. Once reduced, you can make further adjustments to your wedge magnitude by rotating it accordingly. Track your rotation, and when ready, click ‘Reset’ to apply the correction.

After reduction, if helpful, you can also move the fragment to be panned and optimize your cortical apposition.
