Shoulder Arthroplasty replaces the joint with implants for patients suffering from joint disease. Improper placement of the implants can lead to premature prosthetic wear and loosening- a common cause of revision surgery. However, accurate placement of implants is a challenge as reliable positioning and orientation of these components is complicated by the limited surgical exposure. Engineering-based navigation systems to improve the accuracy of implant placement for hip and knee reconstruction have become well established, but have yet to be fully developed and optimized for the shoulder.** The objective of this project is to develop a state-of-the art navigation system for shoulder replacement surgery. We are partnering with Intellijoint Surgical (Waterloo, ON) who have a well-established single mini-optical camera system currently in widespread clinical use for the hip. We propose to adapt this system for use in the shoulder. Our first and main project will be to focus on the design and development of the algorithms, tooling, and procedures required for the successful navigation of shoulder implants to the target positions. This will be based on the Intellijoint platform but suitably modified. Our second study will be to verify our new system using cadaver specimens mounted in our shoulder simulator to assess accuracy of placement. This experiment will compare this navigated approach with the traditional technique currently employed. ** We are confident that the accuracy of placement will be less than 1-mm in translation and 1-degree in rotation and will represent a minimum of a 10-fold improvement over current traditional placement. The successful completion of the proposed research would be significant for Intellijoint Surgical as it would broaden their product portfolio to the shoulder. Moreover, it is highly likely that these advances will lead to better implant performance with a reduction of loosening and wear of the implants, thus improving the quality of life for patients in Canada. ************

肩关节置换术是为患有关节疾病的患者使用植入物替代关节。植入物放置不当可能导致假体过早磨损和松动-这是翻修手术的常见原因。然而，植入物的准确放置是一个挑战，因为这些组件的可靠定位和定向由于有限的手术暴露而变得复杂。用于提高髋关节和膝关节重建植入物放置准确性的基于工程的导航系统已经得到了很好的建立，但尚未完全开发和优化肩关节。** 本项目的目标是开发一种最先进的肩关节置换手术导航系统。我们正在与Intellijoint Surgical（Waterloo，ON）合作，该公司拥有成熟的单微型光学摄像机系统，目前广泛用于髋关节的临床应用。我们建议将该系统用于肩部。我们的第一个也是主要项目将专注于设计和开发将肩关节植入物成功导航到目标位置所需的算法、工具和程序。 这将基于Intellijoint平台，但进行了适当修改。我们的第二项研究将使用安装在我们的肩关节模拟器中的尸体标本来验证我们的新系统，以评估放置的准确性。 本实验将比较这种导航方法与目前采用的传统技术。** 我们有信心，放置的准确性将小于1毫米的平移和1度的旋转，并将代表一个最低的10倍的改善，比目前的传统放置。拟议研究的成功完成对Intellijoint Surgical具有重要意义，因为它将其产品组合扩展到肩部。此外，这些进展很可能会导致更好的植入物性能，减少植入物的松动和磨损，从而改善加拿大患者的生活质量。 ************
