[The sacroiliac joint after hip arthrodesis (author's transl)].

After an introductory chapter about the anatomy and the function of the sacroiliac joint we examined the influence of an arthrodesis of the hip joint on the sacroiliac joint. We observed that an arthrosis of this joint is being formed because of the change in statics and dynamics, which appears radiologically, but rarely clinically. Subjective symptoms, if existant, have their cause mostly in alterations of the lumbar spine. Finally we observed that alterations of the sacroiliac joint after an arthrodesis of the hip joint are mostly insignificant for the patient and do not influence the success of this operation.
