title: Similar radiologic lesions of localized Scheuermann's disease of the lumbar spine in twin sisters.
abstract: BACKGROUND
  Hereditary and mechanical factors are considered to be the principal etiologic factors of Scheuermann's disease.
  
  
  OBJECTIVE
  The authors report identical twins presenting similar lesions of localized lumbar osteochondrosis, which were worse in the one twin that practiced strenuous sports activities.
  
  
  CONCLUSIONS
  These observations suggest, at least in some of these patients, a basic role for genetic factors in the occurrence of the disease and an influence of mechanical strain on its severity.
