ABSTRACT

Background: The peripheral nerve injuries are devastating for the patient; the classic reconstructive options are the Nerve Graft and Tendon Transfers. Lately the Nerve Transfers are being used more and more broadly. They are an excellent option on early injuries and when the motor plate is still alive. The advantages are numerous, because the functional recovery is much better. Methods and results: We report the case of a patient who sustained and injury on the median and ulnar nerve, so the EDQ and ECU branches were used to restore the Ulnar Intrinsic Function. The 4-year follow-up showed good results. Conclusion: The ulnar intrinsic innervations provide dexterity; fine motor function and pinch, which is essential for a functioning hand. The most popular donor to restore the function of the motor branch of the ulnar nerve is the anterior interosseous nerve. When this is unavailable the use of the redundant branches of the EDQ and ECU must be considered.


Key words: Nerve transfer, ulnar intrinsic muscles, AIN, microsurgery.
