The author discusses the early results of primary and delayed microsurgical sutures of the median (31) and ulnar (32) nerves in injuries (incised wounds) to the forearm in the middle and lower third. The results of the operation were appraised in follow-up periods of 2 to 4 years in 19 patients (23 nerves). The useful degree of restoration of the strength of the small hand muscles (3 marks and more) was recorded after suturation of 13 of 23 nerves. Skin sensitivity in the autonomous nerve zones was estimated as 4 marks and more in all cases. Two-point discrimination at a distance of less than 15 mm was restored after suture application in 13 of 23 nerves.
