Résumé
[Objective]To probe into the causes and treatments in the radial nerve injury.[Method]Twenty-nine patients with radial nerve injury were treated.Conservative measures were anti-inflammatory,repercussion,nervous pharmacotherapy,acupuncture and physiotherapy.Surgical interventions included open reduction and internal fixation,tenorrhapy,neurorrhaphy and decompression of nerve.[Result]The outcome of treatment was evaluated with the result of 19 excellent,8 good and 2 fair,in which nerve healing period was at an average of 4 months.[Conclusion]The overall effect was satisfactory in this series,among which,electro-neurogram were inconsistent with their symptoms and signs.It is important to asses the quality and degree in injury to the nerve for guiding the treatment.During internal fixation of the fractures of humerus,the exclusion and protection of the radial nerve should be carefully done.when removig the fixation the radial nerve would be protected by first dissecting normal radial nerve in distal and proximal segments,then,exposing gradually adherent segment within the scar tissue.In brief,the opportunity of injury to the radial nerve may be reduced by careful operation.
Résumé
Objective To observe the histomorphological changes of sciatic nerves following pasteurizing warm temperature treatment. Methods The 12 mm left sciatic nerve from healthy adult male Wistar rats was pasteurized at 60℃ for 30 minutes and observed at the first week (1-week group) and the sixth week (6-week group), 15 rats per group. Number, diameter and area ratio of the myelinated axons in the control (proximal to the treated part), treatment and peripheral nerves (distal to the treated part) were calculated. The histomorphological changes were examined with electrophysiological and electron microscopies. Results (1) In the peripheral part, the number of the myelinated axons was significantly decreased in the 1-week group compared with the control group (P
