This is an example of abnormal uterine activity.

This condition is a localized, persistent area of spasm around the uterus.

It is very rare and results from the administration of an oxytoxic.

A constriction ring may occur around the neck of the foetus or may result in retaining the placenta after delivery of the baby.
