Abstract:
Objective:To probe into the mechanism of the formation of neuroma and stump pai n,and the development of nerve fibres after the proximal ends of peripheral nerv e were bridged by pedicled skeletal muscle.Methods:Forty Wister white rats were randomly divided into experimental group an d control group.The left sciatic nerves of all the rats were transected at the s ame level,and the distal parts of nerves were cut off. The proximal end of the t ransected sciatic nerve in th experimental group was longitudinally divided into two parts,and the two ends were bridged by pedicled skeletal muscle.The proxima l ends of sciatic nerves were left in situ.The sciatic nerves were detected afte r 16 weeks.Results:In experimental group,the regenerated nerve fibres grew into skeletal mu scle bridge via anastomosis and distributed among the skeletal fascicle,and ther e was no formation of neuroma.Conclusion:The pedicled skeletal muscle bridging of the proximal ends of the amp utated peripheral nerves may prevent the formation of neuroma.
