BACKGROUND Complex peripheral nerve injuries of the hand include at least 300,000 cases per year in Europe. The standard treatment involves a microsurgical end-to-end suture of traumatic sensory nerve lesions of the hand without a gap. The objective of this study protocol is to evaluate whether the additional use of a chitosan nerve tube in primary repair of traumatic sensory nerve lesions of t...

objective: to determine the effects of local administration of platelet rich plasma (prp) on peripheral nerve regeneration in rat sciatic nerve transection model. methods: forty-five male white wistar rats were randomized into three experimental groups (n = 15): normal control group (nc), silicon group (sil), prp treated group (sil/prp). in nc group left sciatic nerve was exposed through a glut...

UNLABELLED Muscle denervation atrophy is a result of lower motor neuron injury, thus an early restitution of muscle stimulation is essential in prevention of atrophic changes. THE AIM OF THE STUDY To evaluate the new application of naturally occurring epineural sheath conduit in repair of the peripheral nerve gap to prevent development of muscle denervation atrophy. MATERIAL AND METHODS We ...

Basic fibroblast growth factor (bFGF or FGF-2) has been implicated as a trophic factor that promotes survival and neurite outgrowth of neurons. We found previously that application of FGF-2 to the proximal stump of the injured axon increases retinal ganglion cell (RGC) survival. We determine here the effect of FGF-2 on expression of the axonal growth-associated phosphoprotein (GAP)-43 in retina...

BACKGROUND Short-gap digital nerve injuries are a common surgical problem, but the optimal treatment modality is unknown. A multicenter database was queried and analyzed to determine the outcomes of nerve gap reconstructions between 5 and 15 mm with processed nerve allograft. METHODS The current RANGER registry is designed to continuously monitor and compile injury, repair, safety, and outcom...

introduction: transplantation of bone marrow stromal cells (bmscs) or schwann cells (scs) can increase axonal regeneration in peripheral nerve injuries. based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . we pursued to evaluate the effects of bmscs and scs co-transplant...

Objective-To evaluate effect of chitosan conduit for peripheral nerve regeneration using sciatic nerve transection model in rat Design- Experimental in vivo study. Animals- Sixty healthy male Wistar rats. Procedures-The rats were divided into four experimental groups (n=15) randomly. In sham group the left sciatic nerve was exposed through a gluteal muscle incision and after careful...

A nerve gap is defined as the distance between two ends of a divided nerve. It is caused not just by the nerve tissue lost due to the trauma, or to the following debridement, but also by the actual retraction of the nerve stumps. The retraction is due to the elastic properties of the nerve fibers. Only small nerve gaps, in which minimal tension is required to contrast the elastic properties of ...

background: effects of platelet-derived growth factor b (pdgf-b) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. materials and methods: forty‑five male, white wistar rats were divided into three experimental groups (n = 15), randomly: normal control group (nc), silicon group (sil), and pdgf‑b treated group (sil/pdgf). in nc group, left sciatic nerve was...
