By the presentation of the clinical material a series of 14 cases of the radial nerve microsurgical reparation has been analyzed with the reference to the modern achievements in this field and the possibilities of its quicker and better rehabilitation have been quoted. In our material we used the intraneural microsurgical technique with the direct funiculoraphy (3), the interfascicular nerve transplantation (8) and the external and internal microneurolysis (3). Twelve reconstructed radial nerves were evaluated by these methods. The successful motoric function (M3 and more), with the performance of will-power in the proximal and distal muscles, which spontaneously act on the resistance, and with the independent finger movements, have been detected in 84% of the cases in the period from 8 to 24 months after the reconstruction of this extensor nerve. The state of the contemporary micro-surgery prefers the timely and the exact neurological status, as well as the information on the extensiveness of the radial nerve lesion, on which bases the method for its functional restoration and anatomic rehabilitation should be determined.
