This study presents a novel surgical navigation tool developed in mixed reality environment for orthopaedic surgery. Joint and skeletal deformities affect all age groups and greatly reduce the range of motion of the joints. These deformities are notoriously difficult to diagnose and to correct through surgery.
We have developed a surgical tool which integrates surgical instrument tracking and augmented reality through a head mounted display. This allows the surgeon to visualise bones with the illusion of possessing "X-ray" vision. The studies presented below aim to assess the accuracy of the surgical navigation tool in tracking a location at the tip of the surgical instrument in holographic space.
Results show that the average accuracy provided by the navigation tool is around 8 mm, and qualitative assessment by the orthopaedic surgeons provided positive feedback in terms of the capabilities for diagnostic use.
More improvements are necessary for the navigation tool to be accurate enough for surgical applications, however, this new tool has the potential to improve diagnostic accuracy and allow for safer and more precise surgeries, as well as provide for better learning conditions for orthopaedic surgeons in training.
本研究提出了一种新的混合现实环境下的骨科手术导航工具。关节和骨骼畸形影响所有年龄段的人群，并大大降低了关节的活动范围。这些畸形很难通过手术诊断和矫正。
我们开发了一种手术工具，通过头戴式显示器将手术器械跟踪和增强现实集成在一起。这使得外科医生能够通过虚拟的“X 射线”视觉来观察骨骼。下面呈现的研究旨在评估手术导航工具在全息空间中跟踪手术器械尖端位置的准确性。
结果表明，导航工具提供的平均精度约为 8 毫米，而骨科医生的定性评估在诊断用途方面提供了积极的反馈。
导航工具需要进一步改进，以使其足够精确适用于手术应用，但是，这种新工具具有提高诊断准确性和实现更安全、更精确手术的潜力，并为骨科培训医生提供更好的学习条件。
