Congenital dislocation of the hip joint(LCC : luxatio coxae congenita)is the most frequent congenital dislocation. We attempted to carry out computer-aided diagnosis(CAD)of LCC by tracing the x-ray image on the display and measuring the hip joint by computer program. We developed software for CAD with Visual C++6.0, and adopted the algorithms of Hilgenreiner's method and Iino's method in our determination of the measurement. We studied 146 examples of hip joints in infants under 1 year of age to obtain the data. It was found that diagnosis by CAD software was equal to physicians' diagnosis in 3-to 4-month-old infants. The ease of diagnosis by this program was confirmed, and it was concluded that computer-aided diagnostic software may contribute to the diagnosis of LCC.
