The aim of the study was to validate a software-based planning method for the Schoettle Point and to evaluate precision and time efficiency of its live overlay on the intraoperative X-ray.
A software-based method was compared with surgeons' manual planning in an inter- and intrarater study. Subsequently, K-wire placement was performed with and without an overlay of the planning. The time used and the precision achieved were statistically compared.
The average deviation between the surgeons (1.68 mm; 2.26 mm) was greater than the discrepancy between the surgeons and the software-based planning (1.30 mm; 1.38 mm). In the intrarater comparison, software-based planning provided consistent results. Live overlay showed a significantly lower positioning error (0.9 ± 0.5 mm) compared with that without overlay (3.0 ± 1.4 mm, p = 0.000; 3.1 ± 1.4 mm, p = 0.001). Live overlay did not achieve a significant time gain (p = 0.393; p = 0.678).
The software-based planning and live overlay of the Schoettle Point improves surgical precision without negatively affecting time efficiency.
本研究旨在验证 Schoettle 点的软件规划方法，并评估其术中 X 光实时叠加的精度和时间效率。
采用组内和组间研究，将基于软件的方法与外科医生的手动规划进行比较。随后，在不叠加和叠加规划的情况下进行 K 线放置。对使用的时间和达到的精度进行统计学比较。
外科医生之间的平均偏差（1.68mm；2.26mm）大于外科医生与基于软件的规划之间的差异（1.30mm；1.38mm）。在组内比较中，基于软件的规划提供了一致的结果。实时叠加显示出明显较低的定位误差（0.9±0.5mm），而没有叠加的误差为（3.0±1.4mm，p=0.000；3.1±1.4mm，p=0.001）。实时叠加并没有显著节省时间（p=0.393；p=0.678）。
Schoettle 点的基于软件的规划和实时叠加提高了手术精度，而不会降低时间效率。
