단순 방사선을 이용한 대퇴골 전염각 측정

Abstract

The measurement of femoral anteversion is an important factor in the treatment of developmental dysplasia of the hip, neuromuscular disorder (cerebral palsy, poliomyelitis), in-toeing gait and so on. Measuremental by the fluoroscpic, biplanar or axial roentgenographic methods, ultrasonogram and computed tomography have been used, but there are some considerations in using the proper method; the economic state of patients, the accuracy of the methods, exposure to the radiation and so on. The purpose of this paper was to introduce a simple and rapid way to measure femoral anteversion. We compared the results between direct measurement and a simple roentgenographic method which presented by Kane et al (1992) using the 32 adult dried femora. The following results were obtained. 1. The results measured by our method were compared with that of the direct measurement (Durham, 1956) of 32 adult dried femora with variable abduction (15, 20, 30 degree abduction in each). The result showed that simple roentgenographic method was reliable to determine the angle of the femoral anteversion statistically. 2. This simple and rapid method was considered useful in clinical application with benefit of less radiatio (about 0.2 centigray) to children.
