Abstract: Objective To introduce a new method for the repair of the bilateral chronic proper digital nerve injuries.Methods From November 2000 to October 2009,40 cases with bilateral chronic proper digital nerve injuries were divided into 3 groups.Fifteen cases in Group A were conducted nerve graft with two end-to-side neurorrhaphy.Thirteen cases in Group B were conducted nerve graft with one end-to-side nerve neurorrhaphy.Twelve cases in Group C were performed nerve transplantation with end-to-end nerve anastomosis.Results After 6-8 months of follow-up,the anaesthesia and pain of the injured fingers disappeared completely and finger pulp was plump with good flexibility in group A.The measurement of the sense was S4-S4+ and 2-PD was 5.0-6.0 mm.The feeling recovery was not synchronization and the operative side felt more obvious in group B.The measurement of the sense was S1-S3 and 2-PD was 7.0～7.6 mm.In Group C,the measurement of the sense was S3-S3+,SI or even blind on the finger pulp,and 2-PD was 7.5～8.5 mm.Conclusion Nerve transplantation with end-to-side nerve anastomosis were a new valuable method for the repair of bilateral chronic proper digital nerve injuries.
