Report of a New Case of Interlocking Heads in a Breech-Vertex Twin Delivery: A Conversation with My Residents

“Locked\r\ntwins” is a rare event occurring in about 1 in every 1000 twin births. A 21-year-old\r\nprimigravida with a 31-week twin pregnancy was admitted for delivery. The head\r\nof the first twin was locked to the chin of the second twin at the top of the\r\nsymphysis pubis. Caesarean section was performed allowing the delivery of both\r\ndead twins. Twins gestations with first twin in the breech presentation raise index of suspicion of potential\r\nlocked twin. However, management of such situation is controversial with\r\nmost authors and colleges recommending\r\ncaesarean section to avoid interlocking heads. We report another rare\r\ncase of interlocking heads and bring up the topic about management of\r\nbreech-first twin deliveries.
