Description
In this presentation from the ISTA 2024 conference held in Nashville, experts from New York, France, and Kosovo discuss a groundbreaking approach to ankle replacement surgeries that emphasizes the importance of three-dimensional (3D) modeling to enhance surgical outcomes. They highlight the limitations of current practices that rely on two-dimensional X-rays which may not adequately capture the complexity of patient anatomy. The presenters propose a novel method utilizing standing CT scans to create detailed 3D models of the bone structures involved in ankle alignment. Their technique involves advanced software to segment and align individual bones based on density and anatomical landmarks, allowing for better understanding of how various forces interact during movement.
A key aspect of their research involves analyzing force vectors derived from bone density data, which can provide insights into how to optimize alignment during surgeries. The findings suggest significant variations in internal and external rotations based on different alignments (neutral, varus, valgus), indicating that a more tailored approach to surgery could improve patient outcomes. The researchers aim to use their findings to better inform surgical techniques and potential bone density remodeling strategies to address common issues such as loosening or subsidence of implants.
The presentation concludes with a call for further research to validate these methods in clinical settings and explore their potential to redefine standards of care in ankle reconstruction.
