Diagram of repair models in each group.

(A) In situ graft group; (B) one sural nerve graft group; (C) two sural nerves cable-style nerve graft group; (D) three sural nerves cable-style nerve graft group. In one sural nerve graft group, two sural nerves cable-style nerve graft group and three sural nerves cable-style nerve graft group, a small gap sleeve suture was used at proximal and distal anasto-mosis with a gap of 2 mm. Rats underwent a transplantation of the common peroneal nerve in situ (in situ graft group, n = 6), and cable-style nerve graft with one sural nerve graft (one sural nerve graft group, n = 6), two sural nerves graft (two sural nerves cable-style nerve graft group, n = 6) and three sural nerves graft (three sural nerves cable-style nerve graft group, n = 6). SN: Sural nerve; CPN: common peroneal nerve.
