OBJECTIVE
The aim of this study was to propose a new computer based method for measuring acetabular angles on hip radiographs and to assess its practicality, sensitivity and reliability for acetabular angle measurement.
METHODS
A total of 314 acetabulum were assessed on 157 pelvic X-ray images. Acetabular angles were measured with both the conventional method (Method 1) and our proposed method (Method 2). All the Acetabular Index (AI) angle, Acetabular Angle (AA) and Acetabular Center (ACM) angle were measured with both methods.
RESULTS
The mean AI angle for Method 1 is 11.02° ± 2.7° and the mean AI angle for Method 2 is 10.08° ± 1.88°, the mean AA angle for Method 1 is 39.5° ± 5.3° and the mean AA angle for Method 2 is 39.36° ± 4.68°, the mean ACM angle for Method 1 is 50.5° ± 6.01° and the mean ACM angle for Method 2 is 55.42° ± 12.43°.
CONCLUSION
Our novel automated method appear to be reliable and practical for acetabular angle measurement on hip radiographs.

目的
本研究旨在提出一种基于计算机的新方法来测量髋关节X线片上的髋臼角，并评估其在髋臼角测量中的实用性、敏感性和可靠性。
方法
对157张骨盆X线图像上的314个髋臼进行评估。采用传统方法（方法1）和我们提出的方法（方法2）测量髋臼角。两种方法均测量所有髋臼指数（AI）角、髋臼角（AA）和髋臼中心（ACM）角。
结果
方法1的平均AI角为11.02°±2.7°，方法2的平均AI角为10.08°±1.88°；方法1的平均AA角为39.5°±5.3°，方法2的平均AA角为39.36°±4.68°；方法1的平均ACM角为50.5°±6.01°，方法2的平均ACM角为55.42°±12.43°。
结论
我们的新型自动化方法在髋关节X线片髋臼角测量中似乎可靠且实用。
证据水平
III级，诊断性研究。
