This Holstein cow presents with right tibial nerve paralysis, characterized by knuckling over of the fetlock and a dropped calcaneal tuberosity, due to the lack of efficacy of the extensor muscles of the tibiotarsal joint and subsequent excessive flexion of the hock. This peripheral nerve lesion is generally associated with traumatic events such as slipping, mounting, or contusions during calving. Clinical manifestation can vary in severity, and the prognosis is more or less favorable depending on the extent of the nerve damage.
Treatment includes NSAIDs and vitamin B1 for several days. Functional recovery of the limb sometimes requires several weeks.
