This study presents and discusses the authors' experience with the accessory nerve (spinal branch)-musculocutaneous nerve anastomosis technique, as well as its advantages and limitations regarding proximal upper limb functional recovery, after trophism restoration of musculature innervated by C5-C6 corresponding nerves. Eight patients operated for upper brachial plexus lesion due to avulsion of corresponding roots (C5-C6) were retrospectively assessed for 2 years. All patients were operated by the same surgical team and submitted to the same surgical technique, that is, accessory nerve (spinal branch)-musculocutaneous nerve anastomosis, with sural nerve interpositioning. We achieved a 75% satisfactory result rate, which corresponded to upper limb functional recovery in 6 cases.
