BACKGROUND Nerve conduction studies or somatosensory evoked potentials (SSEPs) have become an important tool in the investigation of peripheral nerve lesions, and is sensitive in detecting brachial plexus nerve injury, and other nerve injuries. To investigate whether the modified Quad surgical procedure improves nerve conductivity and functional outcomes in obstetric brachial plexus nerve injur...

Sciatic nerve crush injury in rat animal model is one of the most common experimental models used in regenerative research. However, the availability of transgenic mouse for nerve regeneration studies is constantly increasing and, therefore, the shift from rat model to mouse model is, in some cases, necessary. Moreover, since most of the human nerve lesions occur in the upper limb, it is also a...

In nerve transfer, we transfer a physiologically active nerve to a distal, more important but irreparably paralyzed nerve. This surgical procedure is best done early within 6 months of the injury. Nerve transfer can be broadly classified into four categories: (1) Extraplexal; (2) Intraplexal and (3) Targeted nerve transfer. Prime extraplexal donors are the spinal accessory, phrenic and intercos...

  Anatomical vascular variations are rare causes of carpal tunnel syndrome. An aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. This article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radi...

OBJECTIVES Tremor is one of the cardinal features of Parkinson disease (PD) and may cause cumulative trauma-related injury to nerves of the hands. The aim of this study was to assess the electrodiagnostic and sonographic features of patients with PD and to assess the effect of tremor in PD on the median nerve. METHODS We studied 31 hands of healthy control participants (n = 16; mean age ± SD,...

Carpal tunnel syndrome can be secondary in some patients, and vascular anomalies (usually a persistent median artery), median nerve variations, or both are among the etiologic factors. High division of the median nerve proximal to the carpal tunnel (known as a bifid median nerve) is a median nerve anomaly that has an incidence rate of 2.8%. This rare entity is often associated with various abno...

Nerve Injury In article 2200227, Jingwei Xie and co-workers summarize the recent advances in microfluidic nerve injury models, which enable scientists to test various hypotheses regeneration mechanisms. Representative device designs techniques, such as vacuum-assisted axotomy, compression or tension-based physical injury, laser-based chemical are described discussed.
