Spinal Flexion

Cervical flexion myelopathy is thought to arise following compression of the spinal cord by vertebrae or intervertebral discs and dura mater, or from overstretching of the spinal cord induced by cervical spinal flexion. However, the influence of spinal flexion on the spinal cord and the detailed origins of this disease are unknown. In this article the authors report a case of cervical flexion myelopathy in which dynamic electrophysiological examination was performed using an epidural electrode. This investigation showed the real-time influence of flexion of the cervical spine on spinal cord function. This technique was considered to be useful for diagnosis and in decision making for treatment. Anterior fusion was the optimal surgical method for treating this disease.

Progressive Disorder

Abstract CERVICAL SPONDYLOSIS IS the most common progressive disorder in the aging cervical spine. It results from the process of degeneration of the intervertebral discs and facet joints of the cervical spine. Biomechanically, the disc and the facets are the connecting structures between the vertebrae for the transmission of external forces. They also facilitate cervical spine mobility. Symptoms related to myelopathy and radiculopathy are caused by the formation of osteophytes, which compromise the diameter of the spinal canal. This compromise may also be partially developmental. The developmental process, together with the degenerative process, may cause mechanical pressure on the spinal cord at one or multiple levels. This pressure may produce direct neurological damage or ischemic changes and, thus, lead to spinal cord disturbances. A thorough understanding of the biomechanics, the pathology, the clinical presentation, the radiological evaluation, as well as the surgical indications of cervical spondylosis, is essential for the management of patients with cervical spondylosis.

To explore the nursing intervention measures of microscopy-assisted anterior and posterior fusion in the treatment of lower cervical spine fracture and dislocation.46 patients with fracture and dislocation of lower cervical spine who were treated by microscope-assisted anterior and posterior fusion in our hospital from April 2018 to April 2019 were selected for this study, and divided into observation group and control group according to the different nursing interventions applied by the patients during the treatment. There were 23 patients in the two groups, while the patients in the control group were given routine nursing interventions. The patients in the observation group were given comprehensive nursing interventions. The curative effects of the treatment and nursing interventions in the two groups were observed, sorted out, analyzed and summarized. The changes of psychological status, recovery of spinal cord function, occurrence of complications and quality of life before and after nursing intervention were compared between the two groups.(l) Psychological status: Before nursing intervention, there was no significant difference in psychological status between the two groups, and there was no significant difference (P > 0.05); After nursing intervention, the SDS and SAS scores of patients in the observation group were better than those in the control group, and the difference was statistically significant (P < 0.05); (2) Recovery of spinal cord function: before nursing intervention, there was no significant difference in JOA scores of spinal cord function between the two groups, and the difference was not statistically significant (P > 0.05); After nursing intervention, JOA score of spinal cord function in the observation group was significantly better than that in the control group, the difference was statistically significant (P < 0.05); (3) Complication occurrence: Complication incidence in the observation group was lower than that in the control group, the difference was statistically significant (P < 0.05). (4) Quality of life: before nursing intervention, there was no significant difference in QOL scores between the two groups, and the difference was not statistically significant (P > 0.05); after nursing intervention, the QOL scores of patients in the observation group were better than those in the control group, and the difference was statistically significant (P < 0.05).Through the analysis, it was found that the operation of microscope-assisted anterior and posterior fusion therapy was more complicated and the risk of treatment was greater. The comprehensive nursing interventions throughout the preoperative, intraoperative and postoperative period played a vital role in improving the treatment effect of patients, which was not only conducive to the effective recovery of patients’ spinal cord function. At the same time, it can avoid complications in the treatment process, so as to promote the early recovery of the patient’s condition and improve the quality of life. In general, the application of comprehensive nursing interventions in the treatment of lower cervical spine fracture patients has higher application value, which is worthy of clinical vigorous promotion and.

Cervical Facet

Acute cervical facet fractures are increasingly being detected due to the use of cervical spine CT imaging in the initial assessment of trauma patients. For displaced cervical facet fractures with dislocations and subluxations, early surgery can decompress the spinal cord and stabilize the spine. For patients with non-displaced cervical facet fractures, the challenge in managing these patients is the determination of spinal stability. Although many of the patients with non-displaced cervical facet fractures can be managed with a cervical collar, the imaging needs to be analyzed carefully since certain fracture patterns may be better managed with early surgical stabilization.

Upper burst fracture of Th12-L1 has unique anatomy because it contains lower spinal cord, medullary cone, and diaphragm which separates between the thoracic and lumbar spine.The presence or absence of neurologic deficit is the single most important factor in the decision making. The presence of profound but incomplete neural deficit in association with canal compromise represents an urgent indication of surgical decompression. Antero-lateral direct decompression with trans-thoracic trans-pleural–retroperitoneal approach given the proximity the cord and conus is the most effective method, with inter-vertebral instrumentation with or without lateral fixation or posterior instrumentation.

Optimized and efficient decision-making systems is the burning topic of research in modern manufacturing industry. The aforesaid statement is validated by the fact that the limitations of traditional decision-making system compresses the length and breadth of multi-objective decision-system application in FMS.  The bright area of FMS with more complexity in control and reduced simpler configuration plays a vital role in decision-making domain. The decision-making process consists of various activities such as collection of data from shop floor; appealing the decision-making activity; evaluation of alternatives and finally execution of best decisions. While studying and identifying a suitable decision-making approach the key critical factors such as decision automation levels, routing flexibility levels and control strategies are also considered. This paper investigates the cordial relation between the system ideality and process response time with various prospective of decision-making approaches responsible for shop-floor control of FMS. These cases are implemented to a real-time FMS problem and it is solved using ARENA simulation tool. ARENA is a simulation software that is used to calculate the industrial problems by creating a virtual shop floor environment. This proposed topology is being validated in real time solution of FMS problems with and without implementation of decision system in ARENA simulation tool. The real-time FMS problem is considered under the case of full routing flexibility. Finally, the comparative analysis of the results is done graphically and conclusion is drawn.
