One of the known etiologic factors for locked twins is size of the twins. We report a case of chin-to-chin locked twins that occurred at gestational age of 30\u00a0weeks pus 6\u00a0days.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case summary<\/jats:title>\n                <jats:p>A 27 years-old primigravida Ethiopian mother presented with a history of pushing down pain and passage of liquor of 6 hours duration at gestational age of 30\u00a0weeks plus 6\u00a0days. With a diagnosis of twin pregnancy (first twin non-vertex), abdominal delivery was decided in latent first stage of labor but mother refused caesarian delivery and she was allowed to labor with the hope of achieving a vaginal delivery. In second stage, interlocking twin was encountered and a low vertical cesarean section was done to effect delivery of twins without the need to decapitate the first twin.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Locked twin is a rare obstetric complication.
