Introduction. While practicing neurosurgery, one can encounter traumas of peripheral nerves without their rupture or compression by gross cicatrices. A method of puncture delivery of electrodes for long-term electrostimulation has been proposed for treatment of such pathology.

Material and Methods. This method was used in 38 cases, treated at the Polenov Research Neurosurgical Institute during 1999-2005. Their distribution according to clinical entities was as follows: lesions of the brachial plexus (LBP) due to compression, caused by a posture - 7; injuries of peripheral nerves of extremities due to compression, caused by a posture - 5; LBP due to traumas, operated earlier - 17; injuries of peripheral nerves of extremities due to traumas, operated earlier - 9.

Results. Remote results were studied in 17 cases. A motor function restored up to the score of 4 in 2 cases with injuries of the brachial plexus due to compression, caused by a posture. As for 2 cases with injured trunks of peripheral nerves due to compression, caused by a posture, there was no change of symptoms in one of them, as compared to an initial level; the second patient had restoration up to the score of 5. As far as 10 cases with LBP due to trauma were concerned, 3 patients with syndrome of total impairment of conductivity had no improvement of a clinical picture; a state of the rest cases improved up to the score of 3-4. The situation in a group of patients (3) with lesions of nerve trunks of extremities due to trauma was as follows: restoration up to the score of 4 was watched in 2 cases; one patient had no marked improvement.

Conclusions. Puncture delivery of electrodes for long-term electrostimulation had a good effect on lesions of peripheral nerves with partially impaired conductivity.
