[Results of surgical treatment for traumatic injury of upper extremity peripheral nerves taken from personal material].

A series of 52 patients with peripheral nerve injury, treated operatively is presented. Motor function has been assessed according to Highet (MO-M5). Sensory function has been evaluated according to Nicholson and Seddon (S0-S4). An attempt to show decisive factors for successful peripheral nerve reconstruction. Clinical analysis proved surgical technique, modified with experience gained influences the final result remarkably. Imposition of microsurgical techniques and instrumentation as well as operative microscopy improved efficacy of the treatment. Delay of final reconstruction worsens ultimate outcome. Age of the patient and coexisting injury of the skin, tendons and bone that change conditions of nerve regeneration are also important. The longer the skin nerve graft is the worse motor and sensory recovery.
