[Regeneration of the ulnar nerve under different blood supply conditions].
As the result of examination of 43 patients with injury to the ulna neurovascular bundle the author studied the regeneration of the ulnar nerve in and without reconstruction of the ulnar artery. The outcomes of ulnar nerve autoplasty are better in restoration of the artery than in application of an epineural suture. Sensitivity and tissue trophies increase essentially, the strength of the hand muscles increases to a lesser degree. Reconstruction of the ulnar artery has the best effect on regeneration of the nerve injured on the forearm and above its ramification on the palm. An important factor is early increase of blood supply and oxygenation, which promotes trophics of the graft, and perfusion of the intergrowiny axons and the surrounding tissues.
