An unusual case of uterine rupture. A case report.

An unusual case of uterine rupture in a primigravida, in which the left leg of the infant ruptured through the posterior fundal part of the uterus, is presented. No definitive predisposing cause could be found. Some of the clinical signs and symptoms resembled those of abruptio placentae. Recording of internal uterine pressure revealed increased basal tone and frequent small contractions, as are often seen with abruptio placentae. This could possibly have been due to prostaglandin release from the injured decidua.
