[Camptocormia: an infrequent muscular disease].

The camptocormia is an entity characterized by a kyphosis lumbar reductible in supine decubitus, associated to dysfunctions in computed tomography scans and histologics in the paravertebrals muscles of the lumbar segment. We contribute a new case corresponding to a 70 year-old woman with chronic lumbar pain and kyphosis dorsolumbar reductible, in who the on-line tomography showed compatible images with fatty degeneration and atrophy of the lumbar musculature, discoveries that were confirmed in the histologic study.
