This condition poses significant risks to both the mother and fetuses if not promptly recognized and managed. We report a rare case of chin\u2010to\u2010neck locked twins and highlight the importance of early diagnosis and meticulous intraoperative management.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A 20\u2010year\u2010old primigravida at 9 months of amenorrhea presented with pushing down pain for 12\u2009h and ruptured membranes for 4\u2009h. Clinical examination revealed a twin pregnancy with the first twin in breech presentation and a fetal heart rate of 98\u2013100 beats per minute, while the second twin was in cephalic presentation with a fetal heart rate of 136\u2013138 beats per minute. An emergency cesarean section was performed. Intraoperatively, a chin\u2010to\u2010neck interlocking of the twins was identified. Both twins were successfully delivered through the lower segment transverse uterine incision and careful intraoperative disimpaction without intraoperative complications.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The first twin was a male weighing 1600\u2009g with Apgar scores of 5 and 7 at 1 and 5\u2009min, respectively, and died 1\u2009h postpartum due to respiratory failure related to prematurity and with a possible contribution from intrapartum hypoxia associated with interlocking of the twins. The second twin was a female weighing 1800\u2009g with Apgar scores of 7 and 9, who required brief neonatal intensive care for respiratory distress syndrome and subsequently recovered well. The mother had an uneventful postoperative course.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This case underscores the critical importance of early recognition of locked twins, timely surgical intervention, and careful intraoperative techniques to minimize maternal and fetal morbidity and mortality. Vigilant antenatal surveillance and preparedness in high\u2010risk twin pregnancies are essential to prevent catastrophic outcomes associated with this rare obstetric emergency.<\/jats:p>\n <\/jats:sec>","DOI":"10.1155\/crog\/2974129","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T08:23:56Z","timestamp":1777019036000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Locked Twins in a Primigravida: A Rare Obstetric Emergency Successfully Managed by Cesarean Section\u2014A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"given":"Getahun","family":"Wodalo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6200-6369","authenticated-orcid":false,"given":"Amanuel Admasu","family":"Yayna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amdetsiyon","family":"Yemaneh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adane","family":"Ayza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashebir","family":"Tesfaye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bereket","family":"Worana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Belachew","family":"Shote","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Biranu","family":"Mamo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elsabeth","family":"Samuel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8772-9432","authenticated-orcid":false,"given":"Getu","family":"Kassaye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wokil Wolde","family":"Dana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0275307"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13256-021-02725-5"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.4103\/2141-9248.105676"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.4103\/ijnmr.IJNMR_44_18"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1981.tb00942.x"},{"key":"e_1_2_12_6_2","first-page":"514","article-title":"Twins: Collision, Impaction, Compaction, and Interlocking","volume":"11","author":"Nissen E.
