Fig. 5

Micrographs of orthogonal sections of the sciatic nerve 13 weeks after segmental nerve surgery. Histologic sections of the sciatic nerve distal to and at the surgical site 13 weeks postsurgery of autograft, collagen filled conduit, and hollow conduit with toluidine staining at 100× magnification. For comparison, the sciatic nerve of the nonoperated limb is shown in the left panel. The white arrows indicate myelinated axons. Note the visually decreased diameter of the operated nerves compared with normal controls. Due to processing difficulties, seven samples were not included in the histology analysis: two autograft at the conduit site, one autograft distal to the graft site, two collagen-filled at the conduit site, and two hollow conduit distal to the conduit site. Color differences are due to staining/drying of toluidine blue
