Uterine torsion represents 9% of dystokia cases in cattle. However, the condition is not widely reported in sheep, possibly because there is less veterinary involvement with dystokia cases and farmers do not recognise the condition. Uterine torsion can be confused with incomplete cervical dilatation. Parturition does not proceed past signs of first stage labour with no appearance of the allantochorion. Vaginal examination is restricted and will not identify torsion cranial to the cervix. In this article Phil Scott describes the use of ultrasound to detect uterine torsion.
