[Iliolumbar syndrome. A syndesmoperiostitis of the iliac crest. Clinical, radiologic and therapeutic summary. Diagnosis with lumbar sciatica. 440 cases].

The authors studied the files of 440 patients with low back pain over a period of 8 years. The constant absence of signs of lumbar sciatica led them to study the aetiology of such a pain. Pain in the ilio-lumbar ligament is due to the development of a syndesmo-periostitis (syndesmos = ligament) from the ligamentis continual traction on the postero-medial iliac crest. This is a discrete clinical entity described by the term "ilio-lumbar syndrome".
