The purpose of the study is to clarify the access route that is most suitable in sonography of the infant hip for diagnosis of luxation and dysplasia. The process of luxation gives rise to deformation of the hyaline cartilaginous preformed part as well as the osseous acetabulum. These deformations are located in the superoposterior part of the acetabulum. With a posterior exposure only the luxated head of the femur can be imaged sonographically, but the dysplastic acetabulum cannot be diagnosed. In anterior exposures the pathological changes in the superior part of the acetabulum are detected poorly or not at all. The lateral exposure can image all deformations of the acetabulum. The strictly standardized lateral sonographic exposure is hence recommended using a standardized plane of measurement.
本研究的目的是明确在婴儿髋关节超声检查中最适合用于诊断脱位和发育不良的检查途径。脱位过程会导致透明软骨预制部分以及骨性髋臼发生变形。这些变形位于髋臼的后上部。仅采用后侧暴露时，超声检查只能成像脱位的股骨头，但无法诊断发育不良的髋臼。在前侧暴露时，髋臼上部的病理变化很难被检测到或根本检测不到。外侧暴露可以成像髋臼的所有变形。因此，建议使用标准化测量平面进行严格标准化的外侧超声暴露。
