MATERIAL and METHODS: Between January 2004 and February 2009, the patients applied to our clinic who had not operation in posttraumatic period between 6 months-3 years. In all patients, preoperative and postoperative electromyography (EMG) study were performed and the motor straight grading. All patients underwent surgery and muscle biopsy were taken from all cases. The patients were controlled in 1,6, and 12. months.

RESULTS: The mean application time was 10 months. 23 of the all patients were male and 2 female and mean age of 26.6 years. The most common cause in the etiology is stabbing injury with 12 cases (%48) in our study. 8 sciatic nerve (%32) and 8 peroneal nerve (%32) most frequently injured. Interfascicular anastomosis with nerve greft 3(%12), fascicular repair 6(%24), external neurolisis and decompression 12(%48), ephineurotomy and internal neurolisis 4(%16), were the surgical treatment methods. Fascicular repair in patients, the results of EMG and motor functions were found to be the best improvement.

CONCLUSION: Following the well established microsurgical techniques, we recommend surgical treatment in nevre lesions even in the prolonged postinjury period. Anahtar Kelimeler : EMG, Nerve greft, Peripheral nerve surgery
