RESUMO
Objective To present the functional outcomes of distal nerve transfer techniques for restoration of elbow flexion after upper brachial plexus injury. Method The files of 78 adult patients with C5, C6, C7 lesions were reviewed. The attempt to restore elbow flexion was made by intraplexus distal nerve transfers using a fascicle of the ulnar nerve (group A, n » 43), or a fascicle of themedian nerve (group B, n » 16) or a combination of both (group C, n » 19). The result of the treatment was defined based on the British Medical Research Council grading system: muscle strength < M3 was considered a poor result. Results The global incidence of good/excellent results with these nerve transfers was 80.7%, and for different surgical techniques (groups A, B, C), it was 86%, 56.2% and 100% respectively. Patients submitted to ulnar nerve transfer or double transfer (ulnar þ median fascicles transfer) had a better outcome than those submitted to median nerve transfer alone (p < 0.05). There was no significant difference between the outcome of ulnar transfer and double transfer. Conclusion In cases of traumatic injury of the upper brachial plexus, good and excelent results in the restoration of elbow flexion can be obtained using distal nerve transfers.

The authors present an unusual case of plexiform neurofibroma affecting the upper limb in a patient diagnosed with type 1 neurofibromatosis. Tumor resection was performed on the median nerve. The patient showed maintenance of limb function and remission of symptoms of pain after four years of follow-up.
Os autores apresentam um caso incomum de neurofibroma plexiforme acometendo o membro superior, com diagnóstico de neurofibromatose do tipo 1. Realizou-se a ressecção do tumor no nervo mediano. A paciente evoluiu com manutenção da função do membro e remissão dos sintomas de dor após seguimento de quatro anos.
