A method is evolved whereby the after-potential sequence intrinsic to longitudinal dorsal column myelinated fibers may be studied in isolation from those events occurring in intact spinal cord subjected to an afferent volley. The recovery sequence intrinsic to dorsal column fibers, after refractoriness is over, is characterized by supernormality approximately four to five times greater than tha...

Книга, написанная признанными экспертами, предоставляет необходимую информацию о различных патологиях позвоночника, диагностической оценке, хирургических процедурах и других видах лечения. После вводного общего раздела следуют более углубленные обсуждения дегенеративных заболеваний, детских патологий позвоночника, травм, опухолей, инфекций, воспалительных и метаболических заболеваний. Наряду с ...

Study Design A broad narrative review. Objective Management of spinal disorders is continuously evolving, with new technologies being constantly developed. Regardless, assessment of patient outcomes is key in understanding the safety and efficacy of various therapeutic interventions. As such, evidence-based spine care is an essential component to the armamentarium of the spine specialist in an ...

Revision of older knowledge on spinal deformities shows causing factors in all day life and the source of rotational forces in men in respiration. The role of lordosis as a causative factor can change towards a correcting force, supported by different studies. The thoracolumbar spine is the originating area of many deforming processes.

Regeneration is abortive following adult mammalian CNS injury. We have investigated whether increasing the intrinsic growth state of primary sensory neurons by a conditioning peripheral nerve lesion increases regrowth of their central axons. After dorsal column lesions, all fibers stop at the injury site. Animals with a peripheral axotomy concomitant with the central lesion show axonal growth i...

BACKGROUND Transcranial magnetic stimulation with motor evoked potential monitoring is a non-invasive method for monitoring motor tracts during surgery. However, anaesthetic agents such as propofol and volatile agents reduce responses to single transcranial magnetic stimulation. We assessed an intravenous technique for anaesthesia to allow motor evoked potentials (MEPs) to be monitored using re...

235 April 2010, Vol. 100, No. 4 SAMJ 236 Rugby is increasingly popular in South Africa, with World Cup success following resumption of the country’s international participation. New role models are continuously presented in the media, as a result of the numerous national and international tournaments. However, the risk of spinal column injury in rugby is perceived to be higher than in other spo...

Injuries in cervical spine X-ray images are often missed by emergency physicians. Many of these missing injuries cause further complications. Automated analysis of the images has the potential to reduce the chance of missing injuries. Towards this goal, this paper proposes an automatic localization of the spinal column in cervical spine X-ray images. The framework employs a random classificatio...

Forestier and Rotes-Querol (1950) described a disease of the spinal column, occurring mostly in elderly persons and frequently mistaken for ankylosing spondylitis, which they designated "hyperostose ankylosante vertebrale senile". The clinical manifestations of this disease are characterized by a decreased mobility of the spine, caused by bony outgrowths bridging the anterior and lateral faces ...
