What Physicians Need to Know

Specialization

Disior specializes in automated 3D medical image analysis and surgical planning software, particularly for orthopedics, focusing on foot and ankle, hand and wrist, and craniofacial workflows, including maxillofacial, wrist, and orbital fractures.

Key Differentiators

Disior's core differentiator is its Bonelogic® 3D analytics software, which converts CT/CBCT/MRI scans into objective, patient-specific mathematical models and quantitative metrics. This enables accurate and rapid diagnosis, automated measurements, fracture detection, visualization for planning, and strength and durability modeling, moving beyond subjective 2D image analysis. The software is clinically approved (Class IIb EC and Class II FDA clearance) and designed for direct use by surgeons.

Technology Stack

Disior's technology is built on advanced engineering and mathematical modeling, transforming 3D imaging data (CT/CBCT/MRI) into automated 3D models and numerical analyses. It leverages robust feature detection algorithms for automated landmark extraction and longitudinal axis measurements, ensuring excellent repeatability. The software is DICOM compliant and PACS compatible. It operates on standard Windows 11 PCs with a dedicated graphics card and connects to the Disior Cloud.

Orthopedics - Foot & Ankle

Disior provides anatomy-specific modules for foot and ankle conditions, offering automated analytics for hindfoot, midfoot, forefoot, hallux valgus, and minimum joint gaps. It assists in diagnosing and planning surgery for conditions like Progressive Collapsing Foot Deformity (PCFD) and hallux valgus, using weight-bearing CT images to create 3D models and provide measurements.

Orthopedics - Hand & Wrist

The software offers automated analytics for hand and wrist, describing radius and ulnar, carpal alignment, and minimum joint gaps, with proven applicability for fracture diagnoses and complex cases like four-corner fusions.

Maxillofacial & Orbital Fractures

Disior's CMF Orbital module provides automated analytics for orbital shape, volume, surface area, fracture position, and maximum prolapse, with excellent applicability for orbital floor fractures.

Physician Tip

For physicians, Disior's Bonelogic® software offers a transformative approach to diagnostics and surgical planning by providing objective, quantifiable 3D data from medical images. This can lead to more precise diagnoses, personalized surgical plans, reduced operating time, and improved treatment outcomes. The automated analysis reduces manual labor and potential human error associated with traditional 2D image interpretation. The ability to virtually plan treatments in 3D with live bone alignment measures and visualize findings can also enhance patient engagement and understanding of planned procedures. The software is designed to be user-friendly and can be operated directly by surgeons.

Disior's Bonelogic® software is DICOM compliant and PACS compatible, facilitating easy transfer of medical images and 3D data within clinical institutions. Since its acquisition by Paragon 28, Disior's technology underpins Paragon 28's SMART 28™ ecosystem, which provides comprehensive pre-operative planning, intra-operative support, and post-operative evaluation for foot and ankle surgeons.
