Uterine torsion has low incidence in small ruminants, which causes the dystocia. This presented report describes, for the first time, partial foetal retention due to the dystocia resulting from unilateral partial uterine horn torsion in a ewe. A pregnant Merinos breed ewe was presented with the history of dystocia. Anamnesis pointed out that a half foetus was removed and cranial parts of the foetus were in uterus. Clinically, abdominal distension and pain were observed. Vaginal examination revealed an opened cervix, and a left sided located fetal part was felt by palpation; however, it was not possible to reach the foetus due to uterine horn torsion. Radiography showed the remained cranial parts of the foetus. Considering the clinical and radiological findings, caesarean section was performed. Abdominal exploration revealed 270 degrees clockwise rotated left uterine horn, which was at cranial 1/2 part of the uterine horn. After the removing of the foetal parts, all incisions were sutured routinely. Analgesic and antibiotic medications were recommended to the owner. It was informed that ewe was healthy at postoperative ten days.
