A 3D-engineered porous conduit for peripheral nerve repair
End-to-end neurorrhaphy is the most commonly used method for treating peripheral nerve injury. However, only 50% of patients can regain useful function after treating with neurorrhaphy. Here, we constructed a 3D-engineered porous conduit to promote the function recovery of the transected peripheral nerve after neurorrhaphy. The conduit that consisted of a gelatin cryogel was prepared by molding...
متن کاملUse of Chitosan Conduit for Bridging Small-Gap Peripheral Nerve Defect in Sciatic Nerve Transection Model of Rat
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...
متن کاملChallenges for Nerve Repair Using Chitosan-Siloxane Hybrid Porous Scaffolds
The treatment of peripheral nerve injuries remains one of the greatest challenges of neurosurgery, as functional recover is rarely satisfactory in these patients. Recently, biodegradable nerve guides have shown great potential for enhancing nerve regeneration. A major advantage of these nerve guides is that no foreign material remains after the device has fulfilled its task, which spares a seco...
متن کاملEngineering a multimodal nerve conduit for repair of injured peripheral nerve.
Injury to nerve tissue in the peripheral nervous system (PNS) results in long-term impairment of limb function, dysaesthesia and pain, often with associated psychological effects. Whilst minor injuries can be left to regenerate without intervention and short gaps up to 2 cm can be sutured, larger or more severe injuries commonly require autogenous nerve grafts harvested from elsewhere in the bo...
متن کاملCollagen-chitosan nerve guides for peripheral nerve repair: a histomorphometric study.
Currently a wide variety of polymer materials are being applied to fabricate nerve guide tubes to repair injured peripheral nerves. In this study we have examined whether collagen-chitosan nerve guides promotes nerve repair compared to chitosan nerve guides using histological analysis. Results indicates that the enclosed structure of the nerve guide both promotes and supports axonal sprouting. ...
