Mortality of spinal cord trauma has been analysed. An analysis included 3,486 patients treated early after spinal trauma in 1965-1989. Life threat in patients, who underwent trauma to the spinal cord embraces several factors. The most important is are: the level and degree of the lesion to the spinal cord, certain causes precipitating severe lesions to the nervous system, advanced age, and--to some degree--accompanying lesions, way of therapy, advances in medical technology, and intensive treatment technics. Available data indicate that the life of patients admitted to the hospital with symptoms of complete interruption of the cervical segment of the spinal cord is threatened to the highest degree. Falls from heights (scaffolding, roofs etc.), and certain road accidents are particularly dangerous. A special group of accidents is fall from the horse carriage in which advanced age of the victims plays the most important role. Mortality rate in the elderly is about tenfold higher, than in the group of subjects under 20 years with the same degree of lesions to the spine. 相似文献

Since 1974, clinical experiments have been conducted at the Rehabilitation Clinic in Konstancin (Poland) on the effects of electrostimulation on the damaged spinal cord. 30 patients with stimulation after injury to the cervical spinal cord are reported. Patients with complete and incomplete cervical cord injury were compared. The patients were treated by surgical decompression with simultaneous implantation of stimulating electrodes in contact with the spinal cord. The control group of patients were operated upon in the same period for similar injuries, but had no stimulators implanted. Neurological improvement was better in the stimulated compared to the nonstimulated patients, both as regards number of neurological improvements as well as quality of neurological function. The comparison also confirmed a favorable effect of spinal cord stimulation on the development of bladder automatism. 相似文献

Dorsal root entry zone lesions in the treatment of pain following brachial plexus avulsion, spinal cord injury and herpes zoster 总被引:3,自引:0,他引:3
This paper details the long-term results in patients treated with dorsal root entry zone (DREZ) lesions for the treatment of pain following brachial plexus avulsion, spinal cord injury, and herpes zoster. With our current operative technique, 82% of patients with brachial plexus avulsion injuries were afforded long-term pain relief. Patients with pain confined to dermatomes just below the level of spinal injury also did well with DREZ lesions, although the results were less good in patients with diffuse pain or with sacral pain. The postoperative results in patients with postherpetic pain were disappointing. 相似文献

Damage to the spinal cord had not been recognised initially in 15 patients out of a consecutive series of 353 admitted over a decade to the National Spinal Injuries Centre with paralysis due to trauma to the cord. In some patients the missed diagnosis led to mismanagement and a greater neurological deficit. Missed injuries of the spinal cord are seen in patients with multiple injuries and head injuries and in those without any paralysis. Various radiological errors contribute to the failure to recognise the vertebral injury. In addition to causing severe disability to the victim these missed and mismanaged injuries of the spinal cord cost the National Health Service large sums in compensation. A careful evaluation of the history of each accident, with greater awareness of the potential of certain types of accidents to cause spinal cord injury, should reduce the incidence of missed injuries of the spinal cord. 相似文献

After spinal cord injury, transected axons fail to regenerate, yet significant, spontaneous functional improvement can be observed over time. Distinct central nervous system regions retain the capacity to generate new neurons and glia from an endogenous pool of progenitor cells and to compensate neural cell loss following certain lesions. The aim of the present study was to investigate whether endogenous cell replacement (neurogenesis or gliogenesis) in the brain (subventricular zone, SVZ; corpus callosum, CC; hippocampus, HC; and motor cortex, MC) or cervical spinal cord might represent a structural correlate for spontaneous locomotor recovery after a thoracic spinal cord injury. Adult Fischer 344 rats received severe contusion injuries (200 kDyn) of the mid-thoracic spinal cord using an Infinite Horizon Impactor. Uninjured rats served as controls. From 4 to 14 days post-injury, both groups received injections of bromodeoxyuridine (BrdU) to label dividing cells. Over the course of six weeks post-injury, spontaneous recovery of locomotor function occurred. Survival of newly generated cells was unaltered in the SVZ, HC, CC, and the MC. Neurogenesis, as determined by identification and quantification of doublecortin immunoreactive neuroblasts or BrdU/neuronal nuclear antigen double positive newly generated neurons, was not present in non-neurogenic regions (MC, CC, and cervical spinal cord) and unaltered in neurogenic regions (dentate gyrus and SVZ) of the brain. The lack of neuronal replacement in the brain and spinal cord after spinal cord injury precludes any relevance for spontaneous recovery of locomotor function. Gliogenesis was increased in the cervical spinal cord remote from the injury site, however, is unlikely to contribute to functional improvement. 相似文献

Characteristics of the tonic stretch reflex in spastic spinal cord and head-injured patients 总被引:1,自引:0,他引:1
Spasticity is a known sequelae of spinal cord injury and head injury. We sought to examine whether there were any significant differences in the characteristics or underlying mechanisms of spasticity in these two groups in the chronic period which may be related to the level of injury of the neuraxis. The response to vibration applied to the muscle, or the tonic vibratory reflex, has been shown to be related to the degree of spasticity, and was therefore studied along with phasic reflexes and passive movements. These studies were carried out on cooperative, stabilized patients who were otherwise healthy, 5 with head injuries, and 5 with spinal cord injuries. The patients were examined in a supine position while surface EMG recordings were made of quadriceps and triceps surae muscles bilaterally. Tendon jerk responses, passive and volitional movements, and responses to a powerful vibratory stimulator were measured. In both head injury and spinal cord injury patient groups, a large EMG response was elicited by passive maneuvers, and tendon jerks were exaggerated. The tonic vibratory response, previously shown to be dependent upon brain influence, was present in both groups. These observations suggest that similar suprasegmental mechanisms may be responsible for hypertonia in both head-injured and spinal cord-injured patients. 相似文献

Local capillary blood flow was studied in and around the spinal cord compression focus in humans with spinal injuries in the acute and early periods of the trauma. The effect of the capillary blood flow in the perimedullary network in the region of spinal cord compression on the degree of motor and sensory disturbances was analyzed. The relationship of the increase in capillary blood flow after spinal cord decompression with increases in leg muscle strength and pain threshold was determined. 相似文献

OBJECTIVE--To observe the effects of stimulation of the sacral anterior roots on anorectal and low colonic pressures and to programme implanted stimulators to produce defecation. DESIGN--Prospective study of 12 consecutive patients. SETTING--Spinal injuries unit and university gastrointestinal physiology department. PATIENTS--12 Patients with complete supraconal spinal cord lesions. Their injuries had been sustained at least two years before the study. INTERVENTIONS--A Brindley-Finetech intradural sacral anterior root stimulator was implanted in all patients. Three months postoperatively the stimulator settings were adjusted after measurement of simultaneous anorectal and low colonic pressures. MAIN OUTCOME MEASURES--Full defecation. RESULTS--Six patients achieved complete rectal evacuation of faeces using the implant and subsequently did not require manual help for defecation. For all but one of the patients the total time taken to complete defecation was reduced, and all were free from constipation, the most prevalent gastrointestinal symptom in patients with spinal injuries. CONCLUSIONS--Sacral anterior root stimulators can be programmed to achieve complete unassisted defecation and can considerably improve the quality of life of patients with spinal injuries. 相似文献

Surface electrodes positioned over the S1 and T12 vertebrate and referenced to T6 were used to record spinal potentials evoked by unilateral stimulation of the posterior tibial nerve at the knee. Data were collected on 24 patients who received spinal cord injuries 2 months to 31 years previously. The recording sites were below the level of spinal injury. The lumbosacral evoked potentials (LSEPs) were compared with the results of measurements obtained from 19 neurologically healthy subject. Additional data were collected on each patient to characterize segmental reflex responses and preservation of sensory and motor functions associated with the L5 through S2 segments of the spinal cord. Assuming that the LSEP reflects demonstrate a degree of spinal cord dysfunctions caudal to the area of injury in s substantial number of the patients with spinal cord injury which we studied. 相似文献

Electric stimulation of the diaphragm via the phrenic nerve to induce ventilation has recently been used for the long-term management of chronic ventilatory insufficiency. Since 1973 three patients with inadequate alveolar ventilation have been treated with diaphragm pacing at the Toronto Western Hospital. Two, who had quadriplegia due to lesions of the spinal cord in the upper cervical region and a severe restrictive ventilatory defect, were treated with continuous diaphragm pacing. The third patient required assisted nocturnal ventilation because of primary alveolar hypoventilation. All three patients tolerated the diaphragm pacing well, and pulmonary function tests showed satisfactory gas exchange with the patients breathing room air. This form of therapy seems to be a practical clinical method of managing chronic ventilatory failure in patients with lesions of the upper cervical cord or primary alveolar hypoventilation. 相似文献

Posttraumatic syringomyelia is becoming increasingly recognized as a sequel to major and minor spinal cord injury, paralleling the development and widespread availability of magnetic resonance imaging as a diagnostic modality for evaluating possible spinal pathologic lesions. Delayed, subacute, or progressive neurologic deterioration in victims of traumatic spinal injury with “fixed deficits” should raise the suspicion of posttraumatic syringomyelia. Alternatively, it may present as sensory or motor complaints occurring on a delayed basis after minor spinal trauma causing no initial neurologic impairment. At our institution, we have treated six of eight patients with this condition by shunting fluid from the intramedullary cyst to the peritoneal cavity by means of a simple valveless shunt, resulting in sustained neurologic improvement in five patients. 相似文献

Background
Spinal cord injuries are highly disabling and deadly injuries. Currently, few studies focus on non-traumatic spinal cord injuries, and there is little information regarding the risk factors for complete injuries. This study aims to describe the demographics and the injury characteristics for both traumatic and non-traumatic spinal cord injuries and to explore the risk factors for complete spinal cord injuries.Methods
A retrospective study was performed by reviewing the medical records of 3,832 patients with spinal cord injuries who were first admitted to the sampled hospitals in Guangdong, China. The demographics and injury characteristics of the patients were described and compared between the different groups using the chi-square test. Logistic regression was conducted to analyze the risk factors for complete spinal cord injuries.Results
The proportion of patients increased from 7.0% to 14.0% from 2003 to 2011. The male-to-female ratio was 3.0∶1. The major cause of spinal cord injuries was traffic accidents (21.7%). Many of the injured were workers (36.2%), peasants (22.8%), and unemployed people (13.9%); these occupations accounted for 72.9% of the total sample. A multivariate logistic regression model revealed that the OR (95% CI) for male gender compared to female gender was 1.25 (1.07–1.89), the OR (95%CI) for having a spinal fracture was 1.56 (1.35–2.60), the OR (95%CI) for having a thoracic injury was 1.23 (1.10–2.00), and the OR (95%CI) for having complications was 2.47 (1.96–3.13).Conclusion
The proportion of males was higher than the proportion of females. Workers, peasants and the unemployed comprised the high-risk occupational categories. Male gender, having a spinal fracture, having a thoracic injury, and having complications were the major risk factors for a complete injury. We recommend that preventive measures should focus on high-risk populations, such as young males. 相似文献15.

Functional recovery of paraplegic rats and motor axon regeneration in their spinal cords by olfactory ensheathing glia 总被引:175,自引:0,他引:175
Axonal regeneration in the lesioned mammalian central nervous system is abortive, and this causes permanent disabilities in individuals with spinal cord injuries. In adult rats, olfactory ensheathing glia (OEG) transplants successfully led to functional and structural recovery after complete spinal cord transection. From 3 to 7 months post surgery, all OEG-transplanted animals recovered locomotor functions and sensorimotor reflexes. They presented voluntary hindlimb movements, they supported their body weight, and their hindlimbs responded to light skin contact and proprioceptive stimuli. In addition, relevant motor axons (corticospinal, raphespinal, and coeruleospinal) regenerated for long distances within caudal cord stumps. Therefore, OEG transplantation provides a useful repair strategy in adult mammals with traumatic spinal cord injuries. Our results with these cells could lead to new therapies for the treatment of spinal cord lesions in humans. 相似文献

The influence of exogenous rat growth hormone on spinal cord injury induced alterations in spinal cord evoked potentials (SCEP) and edema formation was examined in a rat model. Repeated topical application of rat growth hormone (20microl of 1microg/ml solution) applied 30min before injury and at 0min (at the time of injury), 10min, 30min, 60min, 120min, 180min, and 240min, resulted in a marked preservation of SCEP amplitude after injury. In addition, the treated traumatised cord showed significantly less edema and cell changes. These observations suggest that growth hormone has the capacity to improve spinal cord conduction and attenuate edema formation and cell injury in the cord indicating a potential therapeutic implication of this peptide in spinal cord injuries. 相似文献

Cell therapy has proven to be a highly promising method in clinical applications, raising so much hope for the treatment of injured tissues with low, if any, self regeneration potential such as central and peripheral nervous system. Neurally induced bone marrow derived mesenchymal stem cells (NIMSCs) as well as olfactory ensheathing cells (OECs) were transplanted in a rat model of sub-acute spinal cord injury and the behavioral and histological analyses were conducted. A balloon-compression technique was used to produce an injury at T8-T9 level of spinal cord. After a week post injury, rats were injected with either NIMSCs or OECs at the center of developing lesion cavity, 3 mm cranial and 3 mm caudal to the cavity. Weekly behavioral assessment using BBB score was done over five-week period post transplantation and finally histological assessment was performed to locate labeled cells in the tissue in order to evaluate the reduction of cavity formation and axonal regeneration. Evaluation of locomotor performance showed significant behavioral improvement in NIMSC group over OEC and control groups. The histological analyses revealed the presence of transplanted cells in the spinal cord parenchyma. Volume of injured area that was occupied with syrinx cavity in NIMSC group was significantly less than control group. In addition, meanwhile neurofilament-positive axons significantly showed higher expression in rats receiving NIMSC compared to the other two groups. In conclusion NIMSC caused both behavioral and histological improvement that potentially makes them a promising candidate for cell therapy approaches of spinal cord injuries. 相似文献

Six patients died with amyloidosis and four patients are living with amyloidosis out of 1,000 with spinal cord injuries who were studied.No correlation was found between Congo red retention and the length of time since injury or the site of the spinal cord lesion. However, it is felt that the longer decubitus ulcer persists, the greater is the probability of amyloidosis. It is believed that decubitus ulcers with secondary osteomyelitis are of primary importance as etiologic factors in amyloidosis associated with spinal cord injuries, and that pyelonephritis plays a very minor secondary role. 相似文献

Mesenchymal stem cell(MSC)therapy has attracted the attention of scientists and clinicians around the world.Basic and pre-clinical experimental studies have highlighted the positive effects of MSC treatment after spinal cord and peripheral nerve injury.These effects are believed to be due to their ability to differentiate into other cell lineages,modulate inflammatory and immunomodulatory responses,reduce cell apoptosis,secrete several neurotrophic factors and respond to tissue injury,among others.There are many pre-clinical studies on MSC treatment for spinal cord injury(SCI)and peripheral nerve injuries.However,the same is not true for clinical trials,particularly those concerned with nerve trauma,indicating the necessity of more well-constructed studies showing the benefits that cell therapy can provide for individuals suffering the consequences of nerve lesions.As for clinical trials for SCI treatment the results obtained so far are not as beneficial as those described in experimental studies.For these reasons basic and pre-clinical studies dealing with MSC therapy should emphasize the standardization of protocols that could be translated to the clinical set with consistent and positive outcomes.This review is based on pre-clinical studies and clinical trials available in the literature from 2010 until now.At the time of writing this article there were 43 and 36 pre-clinical and 19 and 1 clinical trials on injured spinal cord and peripheral nerves,respectively. 相似文献
