The advantage of temporarily maintained posterior paraneurium and external epineurium for indirect nerve repair.

In this report, the advantages of temporarily maintained posterior paraneurium and external epineurium are presented during indirect nerve repair with a nerve graft. By using this technique, it is possible to overcome the retraction of the proximal and distal nerve stumps. In addition, an accurate prediction for the required length of nerve graft can be made and an optimal coaptation can be performed easily since the alignment of the fascicles is maintained.
