Functional recovery is often unsatisfactory after severe extended nerve defects or proximal nerve trunks injuries repaired by traditional repair methods, as the long regeneration distance for the regenerated axons to reinnervate their original target end-organs. The proximal nerve stump can regenerate with many collaterals that reinnervate the distal stump after peripheral nerve injury, it may ...

Surgery of the peripheral nerves is briefly reviewed with special emphasis on the timing and the techniques of nerve repair. The sooner a severed nerve can be repaired, the better the quality of the recovery. While delays of a few months after injury appear to have no serious effect on the out come of nerve sutures, the chances of successful recovery decline after six months. It is not common f...

BACKGROUND The use of biodegradable synthetic nerve conduits for the reconstruction of segmental nerve defects has been extensively reported in both animal and human studies, with a majority of studies evaluating sensory nerve recovery. However, few studies have compared these nerve conduits for functional motor recovery. The purpose of this study was to compare three commercially available, sy...

BACKGROUND Walking track analysis which has been widely used to examine the recovery of gait functions in rats with sciatic nerve injury. PURPOSE The present study was aimed to objectively analyze and quantify the degree of functional recovery in locomotor behavior of rats after inflicting sciatic nerve crush injury. METHODS Wistar rats trained on various runways, viz., narrow beam, grid an...

In the literature nerve injury is not frequently considered a problem in proximal humeral fractures. Only a few studies exist concerning traction injury of nerves in fractures of the proximal humerus after low-velocity trauma. Almost all of them are retrospective and did not use electromyography. Patients with identical fractures can show quite different outcomes, which vary between complete re...

BACKGROUND The aim of this study was to evaluate the contribution of the proximal nerve stump, in end-to-side nerve repair, to functional recovery, by modifying the classic end-to-side neurorrhaphy and suturing the proximal nerve stump to a donor nerve in a rat model of a severed median nerve. METHODS Three experimental groups were studied: a modified end-to-side neurorrhaphy with suturing of...

Traumatic peripheral nerve neurotmesis occurs frequently and functional recovery is often slow and impaired. Induced pluripotent stem cells (iPSCs) have shown much promise in recent years due to its regenerative properties similar to that of embryonic stem cells. However, the potential of iPSCs in promoting the functional recovery of a transected peripheral nerve is largely unknown. This study ...

Thirty-five leprosy patients who had tendon-transfer surgery recovered nerve function postoperatively . The tendon transfers were performed to correct paralytic deformities resulting from ulnar, median and common peroneal nerve damage. Nerve function recovery was found in 2 ' 8% of the hands that had claw-finger correction for ulnar palsy; in 5 · 1 % of the hands that had opponens replacement f...

Peripheral nerve injuries can cause disabilities, social or economic problems. Melatonin, the secretory product of the pineal gland has antioxidant and anti-inflammatory actions. The aim of the present study was to investigate the effect of melatonin on the recovery of sciatic nerve after injury, comparing its effect when given in the light or the dark periods. Forty adult male Albino rats were...

OBJECTIVE Topical cytidine-5'-diphosphocholine (CDP-choline) improves functional recovery and promotes nerve regeneration in sciatic nerve injury in rats. The aims of this study were to test whether systemic treatment with CDP-choline was effective in improving the recovery of injured sciatic nerve, and to determine whether the cytidine and/or choline moieties of CDP-choline contribute to its ...
