Aim of the work
The aim of this work was to describe a series of patients with complete injury to the peripheral nerves of the upper limb (median, radial or ulnar) who underwent microsurgical repair and to determine the mean results of the final outcome regarding to the following five factors: patient age, duration of the preoperative interval, type of injured nerve, manner of repair, and level of injury with the goal of predicting which patients would benefit from nerve repair.
After study of this thesis and on the basis of the obtained results, we conclude as follows:
• In every case of acute injury involving a nerve, the surgeon must decide whether a primary repair or an elective late repair, is the treatment of choice.
• In a clean-cut nerve without defect, immediate primary repair, using trunk-to-trunk coaptation with epineurial sutures, offers an optimal solution.
• In case of a nerve injury associated with other tissue injuries, the decision is better to perform a planned early secondary repair, (early secondary repair is performed during the third week, or later if this is demanded by local conditions), and however, if there is a nerve defect, a nerve grafting procedure must be considered.
• If a decision is made in favor of an early secondary repair or nerve grafting, marking the nerve ends by sutures is not necessary because exploration always starts in normal tissue, exposing the nerves from the proximal or the distal segments.
• If a patient is seen with a nerve lesion after a long time interval, nerve repair is still indicated, especially, if sensibility is the main functional objective.
• Even though recovery continues after 18 months postoperatively, it has been confirmed that major improvements occur during the first postoperative year.
• Two factors out of the control of the surgeon—patient age and level of injury—appear to exert the greatest influence over the outcome of primary nerve repair.
• Although the level of nerve severance significantly influences the outcome of repair, total outcome is significantly worse after high repairs; however, good outcome is possible after repair of proximal injuries of radial nerve as well, making such repairs useful.
• While the evidence suggests that the timing of nerve repair, within broad limits, is of less importance to the eventual outcome than either the patient’s age at injury or the level of the injury, it is nevertheless an important factor and one of the few known to affect outcome over which the clinician may have some control. Thus, unnecessary delay between injury and nerve repair is prejudicial to the eventual outcome.
