Brachial plexus avulsion in dogs - 3: electroneurostimulation of radial, median, ulnar and musculocutaneous nerves

Mônica Vicky Bahr Arias Ângelo João Stopiglia About the authors

The purpose ofthis work was to relate lhe clinicai, neurological and histopathotogical aspects (as described in the sections I and 2 ofthis work) with the obtained results after the electric stimulation of radial, median, ulnar and musculocutaneous nerrves. The electric stimulation of these nerves was realized during the cirurgic act, when the fascicle were obtained for the histopathologic examination. The radial, median and ulnar nerves of ali dogs submitted to electroneurostimulation presented evidences of degeneration, while the musculocutaneous nerve present almost normal functions in 25% of the cases. The interpretation ofthe results obtained from neurologic, histologic and electroneurostimulation examination suggested the almost total involvement of brachial plexus in ali cases. This work emphasized the need for further research in this área with lhe main purpose of recuperating the involved roots.
