Lumbosacral Plexus

Until recently, neuropathologists have been paying great attention to diseases of the peripheral nervous system. Among these diseases, there are often cases of damage to the brachial and lumbosacral plexus. Inflammations of the brachial plexus are observed more often than the lumbosacral plexus, and a number of works are devoted to their study (Dricheue, Erb, Oppenheim, Flaubert, Dejerine - Klumpke, Dejerine, Gysi, Bernehardt, Unger, Kramer, etc.). The question of inflammation of the lumbosacral plexus is poor in literature and, in our opinion, has not been sufficiently developed to date.

This article analyzes the literature related to flaccid paresis and paralysis of the upper extremities in children during the first months of life. This pathology is a heterogeneous group of diseases with different etiopathogenesis. There are various courses of flaccid paresis and paralysis of the upper extremities in children: damage to the spinal cord, brachial plexus, peripheral nervous system to the level of the brachial plexus, and isolated damage to peripheral nerves. According to the time of occurrence, flaccid paresis and paralysis can be divided into three groups: antenatal, intranatal, and postnatal pathology. The main mechanism of occurrence of this pathology is intranatal trauma. More rare causes of flaccid paresis and paralysis of the upper extremities are antenatal conditions of dysplastic and traumatic origin, postnatal damage to the peripheral nervous system due to trauma or infection. Congenital contractures of the upper extremities combined with flaccid paralysis are connected with genetically determined diseases of the lower motor neurons and congenital myopathies, intrauterine injuries of the brachial plexus peripheral nerves. This article discusses the issues of topical and differential diagnosis of this pathology, the clinical picture suitable for each period of the childs life, and the prognosis of the disease. This research will be useful not only for neurologists, but also for specialists of related specialties: orthopedists, physiotherapists, and neonatologists for making correct the diagnosis, providing adequate treatment, and predicting its results.

The Impact

Background Stretch-induced neuropathy of the brachial plexus and median nerve in conventional perioperative care remains a relatively frequent and poorly understood complication. Guidelines for positioning have been formulated, although the protective effect of most recommendations remains unexamined. The similarity between the stipulated potentially dangerous positions and the components of the brachial plexus tension test (BPTT) justified the analysis of the BPTT to quantify the impact of various arm and neck positions on the peripheral nervous system. Methods Four variations of the BPTT in three different shoulder positions were performed in 25 asymptomatic male participants. The impact of arm and neck positions on the peripheral nervous system was evaluated by analyzing the maximal available range of motion, pain intensity, and type of elicited symptoms during the BPTT. Results Cervical contralateral lateral flexion, lateral rotation of the shoulder and fixation of the shoulder girdle in a neutral position in combination with shoulder abduction, and wrist extension all significantly reduced the available range of motion. Elbow extension also challenged the nervous system substantially. A cumulative impact could be observed when different components were simultaneously added, and a neutralizing effect was noted when an adjacent region allowed for unloading of the nervous system. Conclusions The experimental findings support the experientially based guidelines for positioning. Especially when simultaneously applied, submaximal joint positions easily load the nervous system, which may substantially compromise vital physiologic processes in and around the nerve. Therefore, even when the positioning of all upper limb joints is carefully considered, complete prevention of perioperative neuropathy seems almost inconceivable.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Abstract Lesions of the peripheral nervous system (PNS), whether due to injury or illness, commonly result in residual symptoms and signs and, hence, permanent impairment. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) describes procedures for rating upper extremity neural deficits in Chapter 3, The Musculoskeletal System, section 3.1k; Chapter 4, The Nervous System, section 4.4 provides additional information and an example. The AMA Guides also divides PNS deficits into sensory and motor and includes pain within the former. The impairment estimates take into account typical manifestations such as limited motion, atrophy, and reflex, trophic, and vasomotor deficits. Lesions of the peripheral nervous system may result in diminished sensation (anesthesia or hypesthesia), abnormal sensation (dysesthesia or paresthesia), or increased sensation (hyperesthesia). Lesions of motor nerves can result in weakness or paralysis of the muscles innervated. Spinal nerve deficits are identified by sensory loss or pain in the dermatome or weakness in the myotome supplied. The steps in estimating brachial plexus impairment are similar to those for spinal and peripheral nerves. Evaluators should take care not to rate the same impairment twice, eg, rating weakness resulting from a peripheral nerve injury and the joss of joint motion due to that weakness.
