Ushering in Patient Specific Implants and Instruments
In this article:
– Patient specific implants can provide more fit options
– Patient specific implants can increase surgical efficiency
– Artificial intelligence can automate the design process
The standard treatment plan paradigm is shifting away, ushering in a new era of patient specific implants and instruments. Standard implants and instruments are outdated by their many limitations. From a 3D model of the patient’s anatomy, artificial intelligence-powered software can design a patient specific implant that will simplify surgical technique and improve patient outcomes.
Patient specific implants have shown better anatomic fit leading to increased mobility. The mathematical framework of the software design is backed by validation tests to restore stability through range of motion. Notably, patient specific implants address needs that off-the-shelf implants do not, especially for out-of-range bone geometries and disease-specific requirements.
Anatomically matched surfaces prevent overhangs or sizing compromises. Patient specific implants reduce pain and feel more natural, and can also provide faster recovery and better outcomes.
Patient specific instruments improve alignment and increase surgical efficiency. Cutting guides are designed based on the relationship between 3D models of patient anatomy and implant. They are less complex, and surgeons have more confidence in their procedures causing less muscle damage and restoring more natural joint movement. The jigs are made using rapid prototyping and additive manufacturing, and can come sterile for single use.
Artificial intelligence will allow automation of the design process of patient specific implants and instruments. Refining the design process of patient specific implants and instruments makes them more affordable and easier to manufacturer. The standard implant delivery process presents so many challenges includes the number of conventional surgical instrument trays that take up storage space in hospitals.
PSIs come in a single box, reducing the number of trays in the operating room and shortening time to open them during surgery. PSIs are also single use and sterile, saving the hospital time and money on cleaning and reducing the risk of infection. Mass customization of patient specific instruments drives down procedural cost and maximize patient outcome.
The Intelligent Surgery™ Platform by Enhatch delivers patient specific implants and instruments through a mobile planning application for surgeons. Surgeons can review radiographic images and 3D models, allowing them to select and modify parts. Surgeons can collaborate with device engineers to provide more options for the patient.
