[Roentgen examination in recurrent shoulder luxation--value of different exposure technics].

Clinical and radiological examination was done in 61 patients in whom a Bankart procedure had been performed. In an X-ray follow-up the value of different techniques proving the Hill-Sachs-lesion and degenerative changes of the bony glenoid rim, as described in literature, was investigated. Eight X-rays were performed in each patient. Most of the Hill-Sachs-lesions (76%) were found by internal rotation of 60 degrees in a.p. direction. A three dimensional idea can be obtained by an additional X-ray in tangential projection. Degenerative changes of the bony glenoid rim were found by the Bernageau technique in 25 percent. Standard X-ray before operation should include techniques in various projections: a.p. and simultaneous internal rotation of 60 degrees of both sides, tangential projection, and X-ray as described by Bernageau.
