3D for Medicine and Orthopedic Surgery

Explore the fundamentals of 3D applications for medicine and orthopedic surgery in this introductory lecture.

Learn to convert a shoulder CT scan into a 3D bone model using the free Invesalius software. Import DICOM files, adjust bone thresholds, and export an SDL file.

Transform a CT scan into a 3D printable file using Invesalius, importing DICOM data, selecting the best series, creating a bone mask, and exporting an STL 3D surface for printing.

Transform ct scan into a 3d file using Horos on Mac, render surface visualization, adjust density, and export the result as an sdl file for further use.

Transform a CT scan into a 3D file using Horos Complete on Mac, enabling precise visualization for medicine and orthopedic surgery applications.

Create a real 3D model to measure clavicle fractures and plan reduction using Rhino, quantify shortening, displacement, and rotation, and design patient-specific guides for surgical alignment.

Create a patient-specific surgical guide to achieve accurate fracture reduction using parallel chookie wires, a digital reduction device, and boolean-designed guides that fit the fracture fragments and direct drilling.

Plan a three-dimensional percutaneous glenoid fracture fixation by selecting screw trajectories, opting for two parallel screws, and creating a patient-specific guide to accurately place screws during surgery.

Design and use patient-specific instruments for the Latarjet procedure based on CT scans, with open-source software, to accurately position guides and screws.

Learn to measure shortening, displacement, and rotation between clavicle fragments to guide fracture reduction. Use Rhino-based planning with planes to rotate the lateral fragment by about 16 degrees for alignment.

Design and 3d print patient-specific guides for osteotomy by converting a CT scan to a 3d model, preparing the STL for planning in CAD software, and validating a 10-degree correction.

Plan glenoid anatomy and design patient specific guides for shoulder surgery by creating central pin guides and using boolean operations to fit the interior glenoid.

Learn to create and draw in 3D a locked clavicle plate for fracture planning, aligning fragments with a normal clavicle reference, and planning screw placement.

Learn how to use Meshmixer to edit STL files from medical imaging, isolate clavicle parts, separate and export components, inspect for errors, repair as needed, and prepare for 3D printing.

Master manual selection in Meshmixer when tools fail, using point picks and brush edits to isolate the scapula and clavicle, repair holes, and prepare models for printing and planning surgeries.

Use Meshmixer's analysis and measure tools to quantify 3D distances in millimeters. Drag points to measure cross planes, ensuring 3D print fit and enabling surgeon-friendly measurements beyond CT slices.

Learn to reduce large mesh files in meshmixer to prevent CAD crashes, shrinking a shoulder model from 100 MB to about 7 MB with a 50% reduction.

Learn to use meshmixer to smooth a shoulder model, remove spikes and artifacts, and create a more rounded, print-ready surface through selective editing and flattening.

Design and draw a 3-D clavicle locking plate implant with locket's and cortico screws, and plan surgical placement using scale references, image editing, and Rhino CAD.

Learn to mirror a right knee over the left knee in Meshmixer for orthopedic applications by separating objects, selecting an axis, and aligning the two knees.

Learn to perform an osteotomy and plan a graft using 3D modeling, including creating planes, performing boolean operations, adjusting rotation, and analyzing distances for accurate surgical planning.

Learn to design a reverse total shoulder arthroplasty implant in CAD by modeling the sphere, baseplate, central pin guide, and screw locations using scapula references.

Create a 3D model of a reverse shoulder arthroplasty from a CT scan using a reference implant. Design the baseplate and central pin guide, and plan screw placements.

Master clean plane cuts in Rhino using MASH primitives to split the model, adjust plane inclination, and color-code interior and exterior parts for evaluation.
