This occurs during parturition of a relatively fetal oversized calf and may be linked to sciatic nerve damage (see below). The obturator nerve controls the motor function of the muscles that adduct the hind legs, so that the animal does the splits and lies down in sternal recumbency like a frog. Immediate treatment is vital to prevent further nerve damage; it should consist of NSAIDs and securing the hind legs with ‘Somerset shackles’. These should be adjusted to prevent the legs from abduction by more than 40 cm for a large cow.
