Correction of this malposture is best achieved with the cow standing in cattle stocks. Forceful straining during correction is prevented by injection of 5mL of 2% lidocaine into the extradural space at the sacrococcygeal site. <br><br>

After 5 minutes the calf’s head and left foreleg are well lubricated and slowly repelled until the calf’s poll is level with the pelvic inlet. By first grasping the calf’s right forearm then the mid-metacarpal region, the elbow and carpal joints are fully flexed which brings the calf’s right foot towards the pelvic inlet. <br><br>

Treatment should include an NSAID which should be given before commencing delivery of the calf; however, the considerable vulval oedema present could also be treated with a single injection of dexamethasone.<br><br>

Antibiotics should be administered for 3 consecutive days because placental retention is likely after dystocia, and there is an increased risk of metritis.
