Augmented Reality-Assisted Microsurgery for Severe Thoracic Ossification of the Ligamentum Flavum: A Case Report.
Cureus
December 2024
Department of Orthopaedic Surgery, The Jikei University School of Medicine, Tokyo, JPN.
Ossification of the ligamentum flavum (OLF) can lead to dural ossification, significantly increasing the risk of complications, including intraoperative nerve injury. The application of augmented reality (AR) and advanced digital technologies in spine surgery has the potential to reduce these risks. This case report highlights a perioperative nerve injury-free microsurgery using elastic image fusion technology, which integrates preoperative imaging with intraoperative computed tomography for a patient with severe stenotic OLF and dural ossification.

Trans-arterial interventions are an increasingly utilized approach for diagnosing and treating a wide range of pathologies, providing superior patient outcomes compared to traditional open surgical methods. Recent advancements in tracking and navigation technologies have significantly refined these interventions, enhancing procedural precision and success. Advanced imaging modalities, such as fluoroscopy, cone beam computed tomography (CBCT), and intravascular ultrasound (IVUS), are frequently used strategies offering critical real-time guidance.

An image guided robot only becomes fully useful with integrated software leveraging image fusion. Image fusion is the process of registering and superimposing imaging data in the same coordinate space and can be helpful to image-guided robotic interventions. Effective percutaneous robotic procedures can utilize real-time image guidance and navigation which are powered by fusion technologies.

Background: Cardiac hypertrophy is a prevalent early pathological manifestation in various cardiovascular diseases, lacking effective interventions to impede its progression. Although oxymatrine (OMT) has shown potential benefits for cardiac function, its therapeutic efficacy and mechanism in cardiac hypertrophy remain incompletely understood. Notably, mitochondrial damage and dysregulated autophagy are pivotal pathogenic mechanisms in cardiac hypertrophy.

In the underwater domain, small object detection plays a crucial role in the protection, management, and monitoring of the environment and marine life. Advancements in deep learning have led to the development of many efficient detection techniques. However, the complexity of the underwater environment, limited information available from small objects, and constrained computational resources make small object detection challenging.
