Abstract:
Imaging and electrodiagnostic studies form an essential part of the evaluation of the patient with traumatic brachial plexopathy, enabling clarification of surgical options, prognostication of outcome and formulation of postoperative management. The primary objective of imaging is to identify pre-ganglionic injury indicative of nerve root avulsion. The presence of one or more nerve root avulsion injuries is a critical factor in surgical decision-making and the prognosis of surgical reconstruction. CT myelography is the current imaging modality of choice for this purpose. Initial electrodiagnos

102 patients with closed traction lesion of the brachial plexus resulting from motor cycle accidents have been studied. The majority were young men, with the dominant arm involved in 64%. 74% of the patients underwent early operative exploration and 54% of these were amenable to at least partial repair. 65% of the patients had sustained irreparable pre-ganglionic injury to at least three roots of the plexus. 74% of the patients had sustained additional injuries in the accident. Subsequent reconstructive procedures were performed in 26% of patients. 60% of the patients regained employment, but

Forty of 136 consecutive patients referred for management of brachial plexus injuries had closed supraclavicular injuries. The results of the initial chest X-rays were available for 29 patients. Nine had avulsion of the C8 and T1 nerve roots from the spinal cord. Eight cases had MR confirmation of lower root avulsion, six of these cases were confirmed surgically and none had any long-term clinical recovery. Twenty had partial brachial plexus injuries without avulsion of these roots. Seven of nine patients with avulsion of C8 and T1 had an extrapleural apical fluid collection. One of these had

Purpose: Determining the patterns of brachial plexus injuries is challenging. Diagnostic methods have been used to facilitate diagnosis, but there is no consensus regarding which tool best complements physical examination (PE). Magnetic resonance imaging (MRI) and nerve conduction studies (NCSs) are instruments with widespread use and feasibility for everyday assessment. In this study, we evaluated the diagnostic performance of these diagnostic instruments and PE. We also assessed the agreement in the PE and diagnostic instrument findings of two experienced and certified hand surgeons. Methods

BACKGROUND: Gunshot wounds (GSWs) to the extremities can result in damage to the neurovascular structure which results in high morbidity and loss of function. According to the Centers for Disease Control report, the incidence of non-fatal GSWs has increased in the past decade. Trauma to the brachial plexus is a type of peripheral nerve trauma that is most difficult to treat due to its complex surgical procedures. Early exploration and reconstruction of peripheral nerve trauma are still being debated to this day. However, most recommend surgical exploration when the suspicion of neurovascular t

It is important to determine whether the lesion in question is pre-ganglionic or post-ganglionic for purposes of surgical planning and prognosis. Diagnostic testing helps the surgeon to not only decide whether surgical intervention is required, but also in planning the procedure, thereby maximizing the patient's chances of early return to function.

Abstract:
IntroductionCardiovascular (CV) dysfunction is the leading cause of morbidity and mortality after spinal cord injury (SCI). SCI causes CV dysfunction primarily by (a) the direct loss of critical medullary control of sympathetic pre‐ganglionic neurons and, (b) the aberrant sprouting of nociceptive afferent fibers within the spinal cord. To promote significant CV recovery after SCI, we developed a triple combination approach to simultaneously promote axonal regeneration to regain the supraspinal vasomotor control as well as to reduce aberrant sprouting of nociceptive afferent fibers in an experi
