Reimagining Surgical Planning
In this article:
– Artificial intelligence can automate 2D to 3D imaging
– Artificial intelligence can generate surgical plans
– Patient specific implants can be designed from 3D bone models
Surgical planning is reimagined with tools that automatically generate 3D models from CT/MRI scans and X-ray images. Radiology is the primary diagnostic tool in orthopedics, but artificial intelligence can provide a higher level of detail with a realistic 3D model of a patient’s anatomy. More advanced applications are planning an individualized procedure, custom implant design, and patient specific instrument ordering.
Artificial intelligence-powered software can render a virtual model in minutes after images are uploaded to a computer. An advanced algorithm is used for auto segmentation, a process which defines bone edges and detects boundaries by statistical shape modeling techniques. This image processing can be accurate and fast, constructing 3D models with perfectly mapped articular surfaces and defined geometric arrangement.
Surgeons can use a 3D model as a superior visual aid to plan a procedure – by drawing cut lines and drill paths, sizing and positioning implants, and even printing a 3D model.
Artificial intelligence can also formulate a surgical plan complete with implant selection and position automatically. The computer calculates the best fit standard implant, reducing bias and detecting hidden patterns. A surgeon can then adjust the size and alignment parameters to their preferences. The precision increases with each new case processed through machine learning.
Artificial intelligence is refining patient specific implants and instruments, making them more affordable and easier to manufacturer, too. Physical cutting guides are designed using calculations based on the relationship between 3D models of patient anatomy and implant. By improving alignment and increasing surgical efficiency, patient specific instruments provide innovative solutions in cases where standard instruments fall short.
Many companies are offering robust planning applications where surgeons can track all of their cases, review radiographic images, render 3D models, select and align parts, collaborate with preoperative planning engineers, and sign case approvals – all from a phone or tablet. Enhatch is collaborating with several of the world’s most forward thinking medical device companies to deliver the next generation of surgical planning tools to the orthopedic market.
