Introduction

  • Uterine torsion is a relatively common obstetrical emergency.
  • Manual correction of uterine torsion is necessary before vaginal delivery of a calf can be attempted.
  • Torsion can vary in severity from mild <90° degree torsion to full >360° torsion.
  • Most cases can be corrected manually per vaginum.

Uses

  • To correct uterine torsion either during mid-gestation or, more commonly, immediately prior to calving.

Advantages

  • Non-invasive.
  • Quick.
  • Relatively simple.

Disadvantages

  • Patient may require cesarean Cesarean section to deliver calf even after torsion is corrected due to inflammation and tissue friability.
  • Can be physically demanding.

Prognosis

  • There are very few studies on prognosis following uterine torsion, however some figures have been reported:
    • 100 day survival rate of 93%.
    • 200 day survival rate of 84%.
    • Culling rate of 57%.
    • High rate of calf mortality associated with uterine torsion (24-71%).
