Cohen A, Cohen Y, Laskov I, Maslovitz S, Lessing JB, Many A.
- A painful uterine scar is one that is still tender between contractions.
- 1/10 of these were rupture so it is not that bad a sign
- without other signs mentioned above, none of them ruptured
- not that specific – 8.2% of cases not rupturing had above signs
Comment – if scar is tender during labor, most of time you will be ok, but watch monitor, peritoneal signs, high riding fetus, or vomiting..
