Step 1: Understanding the Question:
The question identifies a specific complication (winging of the scapula) occurring during a breech delivery and asks to name the associated maneuver. Step 2: Detailed Explanation:
Lovset Maneuver: This is a surgical maneuver used during the delivery of an extended arm in a breech presentation.
Technique: The baby is held by the hips and rotated 180\(^\circ\) while keeping the back upwards and maintaining downward traction. This rotation uses the pelvic friction to bring the posterior arm under the symphysis pubis, where it can then be delivered. The baby is then rotated 180\(^\circ\) in the opposite direction to deliver the other arm.
Complications: If the maneuver is performed forcefully or incorrectly, it can lead to injuries such as fractures of the humerus or clavicle, and damage to the long thoracic nerve, which results in winging of the scapula. It can also cause Erb’s palsy (Brachial plexus injury).
Why not others?
- McRoberts (A): Used for shoulder dystocia in cephalic delivery, not breech.
- Pinard (B): Used for decomposing a frank breech to bring down the legs.
- Woods Corkscrew (D): Also used for shoulder dystocia.
Step 3: Final Answer:
The Lovset maneuver is the specific rotation-traction technique used for arm delivery in breech; winging of the scapula is a potential traumatic complication of this procedure.
