background: considering the common origin of skin and peripheral nervous system, a tube of dermal layer of skin hypothetically can be an ideal conduit for nerve reconstruction. an experimental study performed to evaluate the nerve regeneration of efficacy into a dermal tube. methods: sixty male wistar rats were used. a 10 mm gap was produced in right sciatic nerves. in group a the autogenous ne...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...

introduction: epineural suture and autologous graft are two routine techniques in peripheral nerve surgery. however, their efficiency can be highly limited depending on the type of lesion and the gap between two nerve stumps and because of deficient proper nerve donors. so much interest has been focused on the development of alternative instruments for bridging the nerve gaps. in the present st...

  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...

objective: as effectiveness of the autologous graft in the repair of long nerve defects is very limited an effective substitute is needed. this study was conducted to determine the poled polyvinylidene fluoride (pvdf) tube as an alternative to nerve autograft. materials and methods: the left sciatic nerve was transected in 45 male wistar rats. the animals were then divided randomly into three g...

background: bone marrow and umbilical cord stromal cells are multipotential stem cells that have the ability to produce growth factors that play an important role in survival and generation of axons. the goal of this study was to evaluate the effects of the two different mesenchymal stem cells on peripheral nerve regeneration. materials and methods: in this experimental study, a 10 mm segment o...

the appropriate time for performing transfers in radial nerve palsy is somewhat a controversial matter. brown suggested that it would be advisable to proceed early with the full component of tandon transfers when there is a questionable or poor prognosis for the nerve repair. for example, when there is a nerve gap of greater than 4 cm or when there is a large wound or extensive scarring or skin...
