Partial brachial plexus paresis in three calves.

Abstract

Partial brachial plexus paresis was diagnosed in three calves with unilateral functional lameness in a forelimb based on clinical and neurologic examinations. Clinical signs of radial nerve paresis were the main presenting problems. Electromyography was used to identify the affected nerves with the calves under general anaesthesia. Abnormal spontaneous activity of denervated muscles showed that the radial, musculocutaneous, median and ulnar nerves were compromised. The calves were treated medically, using splint bandages, and with physiotherapy. All calves regained function of the affected legs and normal weight bearing.
