全髋关节置换术中人工髋关节假体尺寸自动识别技术
An Automated Size Recognition Technique for Acetabular Implant in Total Hip Replacement
摘要：
全髋关节置换术（THR）中的术前模板是一种估计植入物最佳尺寸和位置的方法。今天，观察（手动）尺寸识别技术仍用于为患者找到合适的植入物。因此，应开发数字化和自动化技术，以便能够有效地实施植入物尺寸识别过程。为此，我们在THR术前计划中引入了基于髋臼尺寸直径的髋臼植入物尺寸识别新技术。该技术使外科医生能够自动识别数字髋臼植入物尺寸。随机选择10名身份不明患者的X线片，用于测试自动植入物尺寸识别技术的准确性和实用性。根据测试结果，新技术在9项研究中（90%）获得了与观察方法非常接近的结果。
英文摘要：
Preoperative templating in Total Hip Replacement (THR) is a method to estimate the optimal size and position of the implant. Today, observational (manual) size recognition techniques are still used to find a suitable implant for the patient. Therefore, a digital and automated technique should be developed so that the implant size recognition process can be effectively implemented. For this purpose, we have introduced the new technique for acetabular implant size recognition in THR preoperative planning based on the diameter of acetabulum size. This technique enables the surgeon to recognise a digital acetabular implant size automatically. Ten randomly selected X-rays of unidentified patients were used to test the accuracy and utility of an automated implant size recognition technique. Based on the testing result, the new technique yielded very close results to those obtained by the observational method in nine studies (90%).
