We observed that NF[kappa]B and RAGE immunoreactivities were higher around epineurial vessels and endoneurial cells in nerve biopsies from patients with VN than from those with AN and HNPP and immunoreactive cells were usually CD8 (+) T cells.
Great efforts have so far been made to treat amputation neuromas with various surgical procedures, including ligation, epineurial barriers, implantation into bone, centro-central repair, nerve translocation, electrocautery, and silicone caps.
We accomplished this by using a volume conduction model that includes the effect of an off-center in an isotropic nerve bundle surrounded by an epineurial sheath lying in a saline bath.
Epineurial repair involves aligning the nerve ends and placing sutures through the epineurium only.
The suture is a typical nerve anastomosis using epineurial microsutures (10/0 diameter, in general).
