title: [Unusual form of dystocia - constriction ring].
abstract: A rare form of distocia, the constriction ring, is presented. The etiology of this kind of distocia is vague and the diagnosis complicated, almost invariably made only during the cesarean section itself. The increased basal tonus or uterine musculature, always present in this kind of distocia, would indicate the administration of tocolytics but there is too little experience at hand so far.
