**Core Concept**
Internal podalic version is an obstetric maneuver where the obstetrician manually converts a transverse lie to a breech presentation by grasping the fetal feet. This procedure carries risks and potential complications, especially in cases where the fetal presentation is not favorable.

**Why the Correct Answer is Right**
The primary complication associated with internal podalic version for a transverse lie is rupture of the uterus. This is because the manual manipulation of the fetus can cause undue stress on the uterine wall, leading to a tear or rupture. The increased risk of uterine rupture is due to the inherent weakness of the uterine wall in the transverse lie position, making it more susceptible to injury.

**Why Each Wrong Option is Incorrect**
**Option A:** Placental abruption is not directly related to internal podalic version for a transverse lie, although it can occur as a separate complication in pregnancy.

**Option B:** Fetal distress is a potential complication of many obstetric procedures, but it is not the most specific complication associated with internal podalic version for a transverse lie.

**Option C:** Uterine atony is a condition where the uterus fails to contract after delivery, but it is not a direct complication of internal podalic version for a transverse lie.

**Clinical Pearl / High-Yield Fact**
Internal podalic version should be performed with caution and only in situations where the benefits outweigh the risks. The procedure should be avoided in cases of a transverse lie, as the risk of uterine rupture is significantly increased.

**Correct Answer: D. Uterine rupture**
