[Radiological findings in the iliolumbar syndrome].

Radiological and clinical findings were compared in 440 patients with the iliolumbar syndrome, a frequently observed but often unrecognized affection. Anatomical and clinical features relating to the iliolumbar ligament, this illustrious unknown part of the body, are discussed, together with the pain syndromes that arise from it and which are often dissimulated under more familiar terms such as lumbosciatica, too frequently employed as an alibi. Original data concerning the radiological appearances in patients with this syndrome are presented.
