Two-Stage Nerve Graft in Severe Scar: A Time-Course Study in a Rat Model

excessive scarring; paralleling the process in tendon reconstruction of the hand. Inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. Methods:  Thirty female rats (~200 g) were randomly distributed into two groups (n=15...

Comparison of nerve repair with end to end, end to side with window and end to side without window methods in lower extremity of rat

  Abstract   Background : Although, different studies on end-to-side nerve repair, results are controversial. The importance of this method in case is unavailability of proximal nerve. In this method, donor nerves also remain intact and without injury. In compare to other classic procedures, end-to-side repair is not much time consuming and needs less dissection. Overall, the previous studies i...

Bridging Small-Gap Peripheral Nerve Defect Using Silicone Rubber Chamber in the Rat Sciatic Nerve Transection Model

  Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...
