With mediCAD 3D Shoulder - Automatic, simple and accurate measuring methods

Because of the more than 15-year collaboration with many international implant manufacturers, Shoulder 3D includes modern know-how and a monthly updated and amended implant database.

 

X-ray-based 2D planning

In order to obtain the most accurate planning result possible, you should position a reference object (e.g. sphere, rectangular cm dimension) on the joint plane close to the joint while taking the image. For a true AP projection, the scapula lies almost parallel to the film. The software allows you to separate bone areas such as the humerus and glenoid. After you have separated the areas, you can select the prostheses from the implant database and position them in the relevant area, as you normally would in mediCAD®. The integrated 2D module repositions the implants automatically. X-ray-based 2D planning has long been a standard part of diagnostics in hip, knee and shoulder surgery. This particular module is automatically included in mediCAD® 3D Shoulder.

MRT-based planning

mediCAD® endoprosthesis planning features targeted treatment based on the use of advanced image modalities for both diagnosis and treatment. mediCAD® 3D Shoulder allows you to separate the humerus from the glenoid to ensure that you can later reposition the implants. In addition, you can measure the glenoid version and the glenoid inclination. The implants are positioned on the axial and sagittal view.

Automatic bone segmentation and automatic resection

Automatic segmentation is an important building block in preoperative planning for shoulder surgery. Segmentation displays the humerus as a high-resolution three-dimensional image separate from the glenoid. With the help of automatic segmentation, the displayed area can be better visualized in order to determine the condition of the joint and to resect the humeral head, for example.

mediCAD® 3D Shoulder provides two different ways of carrying out a resection. The first option is automatic resection. The plane of the cut or the position of the resection is adapted to the resection specifications of the implant manufacturer. The second option allows you to manually determine the resection plane and move or rotate the cut area as needed in order to perform a correction. All dimensions are adjusted automatically and thus reflect the new situation after the correction has been performed.

Automatic, simple and accurate measuring methods

mediCAD® 3D Shoulder supports shoulder endoprosthetics planning. A large number of classic measurements can be carried out and recorded.

Implants

After more than 15 years of collaboration with a large number of international implant manufacturers, mediCAD® 3D Shoulder boasts the latest expertise and an implant database that is updated and supplemented on a monthly basis. The software allows you to insert anatomical, inverse and modular prostheses. You can correct the glenoid version and recenter it by precisely positioning the individual glenoid components. The planning software provides additional visual information about the positioning of the glenoid component. This real-time visualization enables users to see how the component is positioned in the sagittal plane and the extent to which it deviates from the anatomical glenoid center.

Thanks to the convenient options provided by mediCAD® 3D Shoulder, the individual implant components can be assembled with the help of the implant configurator and placed into the 3D model (the patient’s CT image). In addition to this, the implants can be adjusted, rotated, moved or changed to another implant type. The implant configurator lets you select various shoulder implants from various manufacturers. You can filter the implants according to manufacturer, type, material and size, or even list your individual favorites or those used at the hospital.

Transparent view and implant-bone contact visualization

Each image and each plan is different, has a different objective, or requires a different view. You can use the transparent view to better observe the implants used in their various positions. It is often necessary to visually determine the condition of the bone at the planned implant position. High and low density values can occur at the planned implant location. Higher or lower primary stability can therefore be assumed when the implants are inserted.
