Resumen
Brachial plexus avulsion results from excessive stretching and can occur secondary to motor vehicle accidents, mainly in motorcyclists. In a 28-year-old man with panavulsive brachial plexus palsy, we describe an alternative technique to repair brachial plexus avulsion and to stabilize and preserve shoulder function by transferring the contralateral spinal accessory nerve to the suprascapular nerve. We observed positive clinical and electromyographic results in sternocleidomastoid, trapezius, supraspinatus, infraspinatus, pectoralis, triceps, and biceps, with good outcome and prognosis for shoulder function at 12 months after surgery. This technique provides a unique opportunity for patients suffering from severe brachial plexus injuries and lacking enough donor nerves to obtain shoulder stability and mobility while avoiding bone fusion and preserving functionality of the contralateral shoulder with favorable postoperative outcomes.

This class of hybrid systems is suitable for representing biological systems, high traffic information networks, heavily loaded supply chains, etc. By adopting a Control Theory approach, the contribution of this paper is the characterisation of controllability over sets of equilibrium markings (potential equilibrium points), first inside a single marking region (or linear mode) and later extended to several regions.
