»: Longitudinal clinical and radiographic success of total shoulder arthroplasty (TSA) is critically dependent on optimal glenoid component position.
»: Historically, preoperative templating utilized radiographs with commercially produced overlay implant templates and a basic understanding of glenoid morphology.
»: The advent of 3-dimensional imaging and templating has achieved more accurate and precise pathologic glenoid interrogation and glenoid implant positioning than historical 2-dimensional imaging.
»: Advanced templating allows for the understanding of unique patient morphology, the recognition and anticipation of potential operative challenges, and the prediction of implant limitations, and it provides a method for preoperatively addressing abnormal glenoid morphology.
»: Synergistic software, implants, and instrumentation have emerged with the aim of improving the accuracy of glenoid component implantation. Additional studies are warranted to determine the ultimate efficacy and cost-effectiveness of these technologies, as well as the potential for improvements in TSA outcomes.
全肩关节置换术(TSA)的纵向临床和影像学成功严重依赖于最佳的肩胛盂假体位置。
从历史上看,术前模板制作利用X线片、商业生产的叠加植入物模板以及对肩胛盂形态的基本了解。
与传统的二维成像相比,三维成像和模板制作的出现实现了对病理性肩胛盂更准确、精确的评估以及肩胛盂假体的定位。
先进的模板制作有助于了解患者独特的形态,识别和预测潜在的手术挑战,以及预测假体的局限性,并且它提供了一种术前处理异常肩胛盂形态的方法。
为了提高肩胛盂假体植入的准确性,协同软件、植入物和器械应运而生。有必要进行更多研究以确定这些技术的最终疗效和成本效益,以及改善TSA结果的潜力。
