[Deterioration of the ileo-sacral joints through serious unilateral hip joint diseases (author's transl)]

Based on the clinical and radiological examinations of 95 patients with unilateral restricted movement of the hip, the deformities of ileosacral joint and symphysis are described. The pathological changes of ileosacral joints and symphysis could be demonstrated in cases with severe contractures of the hip. Low grade contractures under 15 degrees have been tolerated over many years.
