[Microsurgical technique in injuries of peripheral nerves part I: clinical study.]

The authors evaluate the quality of regeneration following microsurgery of distal injuries of the nervus medianus and ulnaris. For the evaluation of reinnervation proper and comparison with other authors they emphasize the necessity to respect objective criteria of useful recovery, i. e. a two-point discrimination sensitivity test up to 12 mm in the entire autozone of the nerve. The result of the microsuture depend on the surgeon's experience, on the time interval (injury - final operation) and on age. In early operations useful recovery was achieved by 45 % of the patients of all age groups. In late operations useful recovery was achieved only by 19 % patients, moreover only by patients under 30 years of age. The main prerequisite of high-standard regeneration is early diagnosis and an acute microsurgical operation in a specialized department. Key words: nervus medianus, nervus ulnaris, injury, regeneration, microsurgery.
