Peripheral nerves were first distinguished from tendons by Herophilus in 300 BC. By meticulous dissection he traced nerves to the spinal cord, demonstrating the continuity of the nervous system(1). In 900 AD, Rhazes made the first clear reference to nerve repair. However, not until 1795 did Cruikshank demonstrate nerve healing and recovery of distal extremity function after repair. In the early...

Peripheral nerve injury is a common clinical problem because the dysfunction of distal limb seriously affects patients’ quality of life, and it results in a huge social and economic burden.[1] Repair of peripheral nerve injury is a very complex pathological process. Due to slow nerve regeneration, Wallerian degeneration of nerve stump, tissue adhesion, atrophy of muscles and motor end plates an...

Peripheral nerve injury may result in injury without gaps or injury with gaps between nerve stumps. In the presence of a nerve defect, the placement of an autologous nerve graft is the current gold standard for nerve restoration. The clinical employment of tubes as an alternative to autogenous nerve grafts is mainly justified by the limited availability of donor tissue for nerve autografts and ...

It has been reported that chromaffin cells secrete some neuroactive substances particularly opioid peptides and catecholamines which reduce pain. Adrenal medullary implant, have been used in other injury models to provide an endogenous source of catecholamines. The goal of the present study was to determine whether adrenal medullary implants in the spinal space could repair sensory and ...

Injuries to the peripheral nervous system are major sources of disability and often result in painful neuropathies or the impairment of muscle movement and/or normal sensations. For gaps smaller than 10 mm in rodents, nearly normal functional recovery can be achieved; for longer gaps, however, there are challenges that have remained insurmountable. The current clinical gold standard used to bri...

Peripheral nerves are transected in many traumatic injuries of the extremities. Satisfactory functional regeneration of such nerves often fails to occur after repair with sutures. Possible reasons for these failures include poor alignment of nerves or fascicles, intrusion of scar tissue into the nerve junction, and outgrowth of nerve tissue from the repair site. This animal study describes an e...

Damage to peripheral nerve tissue may cause loss of function in both the nerve and the targeted muscles it innervates. This study compared the repair capability of engineered nerve conduit (ENC), engineered fibroblast conduit (EFC), and autograft in a 10-mm tibial nerve gap. ENCs were fabricated utilizing primary fibroblasts and the nerve cells of rats on embryonic day 15 (E15). EFCs were fabri...

conclusion vr reconstruction for both single-direction images and sushi using dti25 raw data provides excellent 3d displays of the peripheral nerves in the wrist region. sushi post-processing is a useful denoising tool because it automatically reduces the majority of isotropic object noise. results single-direction vr reconstruction clearly showed the nerves for both dti6 and dti25 but with obv...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...
