Peripheral nerve gap repair facilitated by a dynamic tension device.
End-to-end neurorrhaphy remains the gold standard for transected nerve repair. However, the current dogma is that to be successful, nerve repairs must be tension free. Therefore, nerve gaps are most commonly repaired with grafts. While there is evidence that nerves can regenerate successfully after initial approximation under a tensile force, the amount of tension that deters regeneration of hu...
متن کاملTension and creep phenomena in peripheral nerve.
Tension introduced into peripheral nerves during their surgical repair may reduce the success of this procedure. Two mechanical factors are important; the tension required to effect a repair, and the rate at which this tension changes after surgery. These two factors have been investigated in the rat sciatic nerve. The results show an increasing resistance to elongation of the nerves with incre...
متن کاملPeripheral nerve injury and repair.
Peripheral nerve injuries are common, and there is no easily available formula for successful treatment. Incomplete injuries are most frequent. Seddon classified nerve injuries into three categories: neurapraxia, axonotmesis, and neurotmesis. After complete axonal transection, the neuron undergoes a number of degenerative processes, followed by attempts at regeneration. A distal growth cone see...
متن کاملA biomaterials approach to peripheral nerve regeneration: bridging the peripheral nerve gap and enhancing functional recovery.
Microsurgical techniques for the treatment of large peripheral nerve injuries (such as the gold standard autograft) and its main clinically approved alternative--hollow nerve guidance conduits (NGCs)--have a number of limitations that need to be addressed. NGCs, in particular, are limited to treating a relatively short nerve gap (4 cm in length) and are often associated with poor functional rec...
متن کاملNontubulation Repair of Peripheral Nerve Gap Using Heparin/Alginate Gel Combined with b-FGF.
All artificial nerve grafts have a tubular structure, and they guide axonal regrowth through the tube from the proximal side toward the peripheral side. Based on the results of our experimental study using animals, we used alginate gel without a tubular structure as an artificial nerve graft for digital nerve repair and evaluated peripheral nerve regeneration. In 2 patients, a gap due to digita...
