Design outcomes

Primary

Measure	Time frame
In hip sonography the usage of a stabilizing cradle and a probe-guiding system is recommended. Whether the application of these measures offers actual advantages is yet to be examined. This study shall compare hip sonography without assistance systems with hip sonography procedures supplemented only by stabilizing cradle and secondly hip sonography involving combined usage of stabilizing cradle and a probe-guiding system. The main target figure is the examination time.	—
