Which forceps is specifically designed for rotational delivery of a fetus in occipitotransverse or persistent occipitoposterior position?

• A Wrigley's forceps
• B Simpson's forceps
• C Piper's forceps
• D Kielland's forceps ✓

Explanation

Kielland's forceps have a sliding lock, minimal pelvic curve, and directional knobs, features that allow safe rotation of the head from an occipitotransverse or persistent occipitoposterior position without excessive torque on the fetal head. Simpson's and similar axis-traction forceps have a pronounced pelvic curve suited to traction in the occipitoanterior position. Wrigley's are short outlet forceps used at cesarean or for lift-out deliveries. Piper's forceps are designed for the aftercoming head in breech delivery.
