The newer diagnostic modalities such as computed tomography and magnetic resonance imaging are becoming increasingly used in the evaluation of joint trauma. The combination of computed tomography and arthrography can also be of significant diagnostic value in certain specific situations. In our case report, we describe its use in post-traumatic recurrent hip dislocation and its value, not only in depicting a posterior capsular tear, but also in the diagnosis of an internal joint derangement which may contribute to incongruous reduction of the hip joint.
The efficacy of radiographic methods in detecting and classifying facial fractures was assessed.Thirty-one patients with maxillofacial trauma were studied with plain radiography, coronal and lateral pluridirectional tomography (PT), and axial and direct coronal computed tomography (CT). PT and CT were compared to assess how many fractures each method could demonstrate.In addition, plain films were used in combination with each special study to see how efficacious each combination was at classifying fractures into types, such as blow-out, tripod, etc. To reflect the fact that it is sometimes impossible to obtain lateral PT or direct coronal CT scans at this institution, the same analysis was done using just coronal PT and axial CT.
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.
