BACKGROUND Chronic lumbar radicular pain can be described as neuropathic pain along the distribution of a particular nerve root. The dorsal root ganglion has been implicated in its pathogenesis by giving rise to abnormal impulse generation as a result of irritation, direct compression and sensitization. Chronic lumbar radicular pain is commonly treated with medications, physiotherapy and epidur...

in the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. the cranial cervical ganglion was found beneath the mandibular salivary gland. it was located ventromedial to tympanic bulla and ventrally to atlantic fossa. in three out of eight animals it wa...

Neurite outgrowth from dorsal root ganglion (DRG) explants is a method of evaluating neurotrophic activity of growth factors. When complete medium containing collagen was supplemented with nerve growth factor (NGF) DRG outgrowth was observed after 18 h. In the absence of NGF and in the presence of collagen, the DRG outgrowth took place after 72 h. In wells not supplemented with collagen gel in ...

Sacral stimulation is a well-established therapy for urologic neuromodulation. After the advent of dorsal root ganglion (DRG) stimulation, pain surgeons have started to reach this target mostly pelvic and sacral pain. For those without good surgical experience, foramen puncture, especially S3 S4, can be challenge, due its entry angle limited C-arm image resolution. In report, we describe new te...
