摘要

简介:我们开发了一款智能手机应用程序,能够通过捕获显示器上显示的放射图像来自动测量拇外翻角(HVA)和各种跖间角。本研究旨在评估这些测量使用应用程序的准确性。方法:三名用户——一名委员会认证的骨科医生、一名住院医生和一名非医疗保健专业人员(用户1、2和3)——独立地使用该应用程序测量来自92名连续患者的92张x线片的角度。计算每位使用者的应用测量值与三位经验丰富的足部和踝关节外科医生使用DICOM观察器进行的手动测量值中位数之间的平均绝对误差(MAEs)。为了评估测量误差是否可接受的小,进行了单侧t检验,以确定MAEs是否显著小于3°。使用方差分析也评估了三个用户之间MAEs的差异。结果:3名使用者的HVA MAEs分别为1.1°、1.3°和1.4°,均显著低于3°阈值(95% CI上限;1.2°、1.5°和1.5°)。在跖骨间角上观察到类似的准确性,而在更多的外侧跖骨上观察到更大的可变性。所有测量值均满足< 3°的精度标准,除了由非医疗保健使用者测量的第一和第五跖骨之间的跖骨间角。HVA使用者的MAE无显著差异(p = 0.13),而某些跖骨间角有显著差异。结论:开发的智能手机应用程序可以准确测量HVA和各种跖间角,其性能与经验丰富的足部和踝关节外科医生相当。重要的是,即使没有临床培训的个人使用,也达到了足够的准确性。该应用程序可作为临床和研究设置的实用工具。

AI-Powered Smartphone Application for Measuring Hallux Valgus Angle From Radiographs Displayed on a Monitor.

Introduction: We developed a smartphone application capable of automatically measuring the hallux valgus angle (HVA) and various intermetatarsal angles by capturing radiographic images displayed on a monitor. This study aimed to evaluate the accuracy of these measurements using the application.

Methods: Three users-a board-certified orthopedic surgeon, a resident, and a nonhealthcare professional (Users 1, 2, and 3)-independently used the application to measure angles on 92 radiographs from 92 consecutive patients. Mean absolute errors (MAEs) between the application-based measurements and the median of manual measurements performed by three experienced foot and ankle surgeons using a DICOM viewer were calculated for each user. To evaluate whether the measurement errors were acceptably small, one-sided t-tests were conducted to determine whether the MAEs were significantly less than 3°. Differences in MAEs among the three users were also assessed using analysis of variance.

Results: The MAEs of HVA by the three users were 1.1°, 1.3°, and 1.4°, respectively, all significantly below the 3° threshold (95% CI upper limit; 1.2°, 1.5°, and 1.5°). Comparable accuracy was observed for intermetatarsal angles, which have slightly greater variability for more lateral metatarsals. All measurements met the accuracy criterion of < 3°, except for the intermetatarsal angles between the first and fifth metatarsals measured by the nonhealthcare user. No significant difference in MAE was found among users for HVA (p = 0.13), whereas significant differences were noted for some intermetatarsal angles.

Conclusions: The developed smartphone application accurately measured the HVA and various intermetatarsal angles, with performance comparable to that of experienced foot and ankle surgeons. Importantly, sufficient accuracy was achieved even when used by individuals without clinical training. The application may be useful as a practical tool in clinical and research settings.

期刊介绍: Journal of Foot and Ankle Research, the official journal of the Australian Podiatry Association and The College of Podiatry (UK), is an open access journal that encompasses all aspects of policy, organisation, delivery and clinical practice related to the assessment, diagnosis, prevention and management of foot and ankle disorders. Journal of Foot and Ankle Research covers a wide range of clinical subject areas, including diabetology, paediatrics, sports medicine, gerontology and geriatrics, foot surgery, physical therapy, dermatology, wound management, radiology, biomechanics and bioengineering, orthotics and prosthetics, as well the broad areas of epidemiology, policy, organisation and delivery of services related to foot and ankle care. The journal encourages submissions from all health professionals who manage lower limb conditions, including podiatrists, nurses, physical therapists and physiotherapists, orthopaedists, manual therapists, medical specialists and general medical practitioners, as well as health service researchers concerned with foot and ankle care. The Australian Podiatry Association and the College of Podiatry (UK) have reserve funds to cover the article-processing charge for manuscripts submitted by its members. Society members can email the appropriate contact at Australian Podiatry Association or The College of Podiatry to obtain the corresponding code to enter on submission.
