How is uterine rupture defined?

• A. A full thickness separation of the uterine wall including the serosa
• B. A partial separation of the myometrium sparing the serosa
• C. Uterine inversion with placental detachment
• D. Placental abruption without rupture of the uterine wall

Answer: (A)

Uterine rupture means a full-thickness tear through the uterine wall that goes through all layers, including the serosa, often exposing the peritoneal cavity. This complete breach distinguishes it from partial-thickness separations, where the serosa remains intact (uterine dehiscence). The other options describe other obstetric emergencies: uterine inversion with placental detachment is a disordered turning of the uterus, and placental abruption is placental separation without rupture of the uterus. Therefore, the definition that matches a complete, all-layer tear is the full-thickness separation including the serosa.
