摘要
背景：在过去的几十年里，全关节置换术中的引导技术越来越受欢迎。计算机辅助导航（CAN）最近被引入全肩关节置换术（TSA）中肩关节植入。然而，目前尚不清楚CAN TSA的利用趋势。本研究旨在确定从2017年到2023年在TSA中使用CAN的流行程度和趋势。方法：回顾性分析所有使用单计算机导航肩位系统(ExactechGPS；Gainseville， FL， USA)。术中导航仅针对关节盂假体进行。每年报告CAN的使用情况，以确定CAN病例的流行趋势、用户数量、新用户、退出用户、高容量用户（50例/年）和高容量用户完成的病例数。数据还根据TSA类型（aTSA vs. rTSA）和使用的盂骨假体类型（增强或非增强）进行分层。结果：从2017年到2023年，导航tsa从每年654例增加到9777例，导航rTSA的增长大于aTSA的增长。使用增强型植入物的CAN病例增长了1435%，而非增强型植入物增长了1352%。到2023年，CAN用户总数将从79个增加到667个。到2023年，大量使用CAN的外科医生将增加到50人。在此期间，每年由高容量外科医生进行CAN TSA的数量比实际高容量外科医生的数量增长得更快。结论：本研究表明，在过去的八年中，CAN用于TSA的使用呈指数增长。这一增长是由于新用户数量的逐步增长以及现有用户执行的CAN tsa增加了数百倍。这些在TSA中使用制导技术的上升趋势很可能在未来继续下去。
Utilization trends of the ExactechGPS® computer-assisted navigation system in total shoulder arthroplasty
Background
Guidance technology in total joint arthroplasty has gained popularity over the last few decades. Computer-assisted navigation (CAN) was recently introduced for glenoid implantation in total shoulder arthroplasty (TSA). However, utilization trends of CAN TSA are not currently known. This study aims to determine the prevalence and trends of CAN usage in TSA from its introduction in 2017 until 2023.
Methods
A retrospective review was performed of all TSAs (anatomic TSA [aTSA] or reverse TSA [rTSA]) implanted using a single computer navigation shoulder system (ExactechGPS®; Gainesville, FL). Intraoperative navigation was performed for the glenoid component only. Use of CAN was reported per year to determine trends in the prevalence of CAN cases, number of users, new users, dropped users, high-volume users (>50 CAN cases/year), and the number of cases completed by high-volume users. The data were also stratified by type of TSA (aTSA vs. rTSA) and type of glenoid component used (augmented or nonaugmented).
Results
From 2017 to 2023, navigated TSAs increased from 654 to 9777 cases per year, with a greater increase in navigated rTSA than aTSA volume. The number of CAN cases using augmented implants grew 1435% whereas nonaugmented implants grew 1352%. By 2023, the overall number of CAN users increased from 79 to 667 users. High-volume CAN surgeons increased to 50 users by 2023. Over this period, the number of CAN TSA performed by high-volume surgeons increased more rapidly than the actual number of high-volume surgeons per year.
Conclusions
This study demonstrates an exponential increase in the use of CAN for TSA in the last 8 years. This increase is driven by progressive growth in both the volume of new users and CAN TSAs performed by existing users by several hundred folds. These upward trends in use of guidance technology for TSA are likely to continue in future.

The official publication for eight leading specialty organizations, this authoritative journal is the only publication to focus exclusively on medical, surgical, and physical techniques for treating injury/disease of the upper extremity, including the shoulder girdle, arm, and elbow. Clinically oriented and peer-reviewed, the Journal provides an international forum for the exchange of information on new techniques, instruments, and materials. Journal of Shoulder and Elbow Surgery features vivid photos, professional illustrations, and explicit diagrams that demonstrate surgical approaches and depict implant devices. Topics covered include fractures, dislocations, diseases and injuries of the rotator cuff, imaging techniques, arthritis, arthroscopy, arthroplasty, and rehabilitation.
