title: Pseudotibiotalar slant: a positioning artifact.
abstract: Pseudotibiotalar slant is a positioning artifact which duplicates a finding recently reported as a new observation in the ankles of patients with sickel cell anemia and the configuration of tibiotalar slant described in juvenile rheumatoid arthritis, hemophilia, and multiple epiphyseal dysplasia. The configuration was produced on radiographs of the author's ankle by flexion of the knee and external rotation. It is a nonspecific finding which should prompt inquiry into the possibility of ipsilateral knee and/or hip abnormality.
