## Overview Obturator nerve paralysis can occur in mares after difficult foaling when the nerve is compressed in the pelvis. It paralyzes the adductor muscles, so the mare cannot bring the hind limbs together and may splay dangerously on slippery surfaces. Hobbles are often used to prevent the splits. Recovery usually occurs over days to weeks. ## Causes Compression of the obturator nerve during parturition. ## Diagnosis Clinical signs of adductor weakness immediately after foaling, with inability to adduct the hind limbs. ## Treatment Hobbles or slings to prevent splaying, excellent footing, anti-inflammatories, and nursing care. Most mares recover if secondary muscle tearing or hip luxation is avoided. ## Recovery and Prognosis Good if complications are prevented. Splaying injuries worsen the outlook. ## Prevention Assistance with difficult births and immediate use of hobbles if weakness is recognized.
inability to bring the hind limbs together; splaying on slippery surfaces; need for hobbles; usually recognized after foaling
