The X-ray examination of an injured part of a skeleton requires, to obtain a 3-D effect, two vertical levels to one another. The explanation of this radiographic minimum demand is seen especially in the posterior dislocation of the shoulder as the a-p-view with the discrete indirect signs of luxation; this is often misinterpreted as being normal by inexperienced people. Indirect X-ray signs are: fixed internal rotation of the Humerus, "Trough-line", positive "Rim-sign", flattening of the medial aspect of the humeral head and "loss of the normal half-moon shadow" caused by the overlap of the humeral head on the posterior part of the glenoid cavity. The position of the second dimension is brought out with more success using the transscapular or the Velpeau axillary view radiogram without in being painful for the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
