The process of the surgery. (a) Pre-operation. (b) Intra-operation. (c) Post-operation. Three-point star mark the nerve defect points; Four-point star mark the nerve scaffold proximal points; Five-point star mark the nerve scaffold distal points; Six-point star mark the nerve scaffold proximal points rotation 180°; Seven-point star mark the nerve scaffold distal points rotation 180°; Triangle mark the nerve scaffold proximal points rotation 180° and re-implant in distal point; Square mark the nerve scaffold distal points rotation 180° and re-implant in proximal point.
