Electromyographic (EMG) examination demonstrating marked segmental compromise of the posterior primary ramus distal to the spinal root with relative sparing of the anterior ramus may be the earliest objective evidence of paraspinal muscle metastasis. Antecedent studies are often initially normal, failing to disclose the underlying cause of back pain. Although paraspinal muscle metastasis has been histopathologically demonstrated at postmortem, attempts to image the suspected malignancy with computed tomography have been unsuccessful because the tumor in muscle remains isodense. This study reports the use of magnetic resonance imaging (MRI) to substantiate the existence of EMG-suspected paraspinal muscle metastasis. An EMG pattern of segmental posterior primary ramus denervation is not pathognomonic of metastasis. A confirmatory MRI, however, does permit earlier treatment with palliative radiation therapy. 相似文献

This article reviews available techniques for spinal muscle investigation, as well as data on spinal muscles in healthy individuals and in patients with low back pain. In patients with chronic low back pain, medical imaging studies show paraspinal muscle wasting with reductions in cross-sectional surface area and fiber density. In healthy individuals, the paraspinal muscles contain a high proportion of slow-twitch fibers (Type I), reflecting their role in maintaining posture. The proportion of Type I fibers is higher in females, leading to better adaptation to aerobic exertion compared to males. Abnormalities seen in paraspinal muscles from patients with chronic low back pain include marked Type II fiber atrophy, conversion of Type I to Type II fibers, and an increased number of nonspecific abnormalities. Limited data are available from magnetic resonance spectroscopy used to investigate muscle metabolism and from near infrared spectroscopy used to measure oxygen uptake by the paraspinal muscles. Surface electromyography in patients with chronic low back pain shows increased paraspinal muscle fatigability, often with abolition of the flexion-relaxation phenomenon. 相似文献

We report an uncommon case of a 76-year-old woman who presented with lower back pain, an intermittent L5 radiculopathy and a right palpable paraspinal mass. Imaging studies revealed a 7-cm lumbar paraspinal pseudo-cystic soft tissue tumour developed in the paravertebral musculature, without a clear radiological diagnosis. Gross total surgical resection was performed, resulting in complete resolution of pain. Histopathological studies revealed an intramuscular (IM) myxoma.With a low positive predictive value of radiological work-up and a poor yield of percutaneous biopsies, surgery remains the mainstay treatment for these rare soft tissue tumours of the lumbar spine. Intramuscular myxomas show excellent postoperative results. 相似文献

A knowledge of the alteration in the fibre type profile of paraspinal muscle associated with low back pain is essential for the design of successful rehabilitation programmes. In attempting to compare the muscles of patients with low back pain with those of controls, few previous studies have considered factors such as gender, age, and size of the subjects, each of which can potentially confound interpretation of the results. We obtained samples of lumbar paraspinal muscle during spinal surgery from 21 patients with low back pain and, using the percutaneous biopsy technique, from 21 control volunteers matched for gender, age, and body mass. The samples were subject to routine histochemicsl typcal analysis to determine characteristics of muscle fibre type. Compared with controls, the muscle of the patients had a significantly higher proportion of type-IIB (fast-twitch glycolytic) fibres than type- I (slow oxidatve) fibres. The mean size of a given fibre type did not differ between the patients and the controls. Consequently, the relative area of the muscle iccupied by type-IIB fibres was higher and that by type-I fibres Was lower in the patients. The patients had a greater number of muscle samples with more than 1% type-IIC fibres, and abnormalities that could be described as pathological were more marked in the patients than in the controls. In conclusion, the paraspinal muscles of patients who have low back pain display a more glycolytic (faster) profile; this can be expected to render them less resistant to fatigue. 相似文献

OBJECTIVE: To report a case illustrating the usefulness of botulinum toxin A in the treatment of spinal dystonia responsible for low back pain and postural disorders. METHODS: Critical appraisal of a case report. CASE REPORT: A young woman with cerebral palsy had lumbar paraspinal muscle dystonia responsible for pain and hyperlordosis unresponsive to oral medications for muscle spasm. Botulinum toxin A (Botox(R), 200 U) was injected into the paraspinal muscles at six sites, to good effect. DISCUSSION: The few reported cases consistently show a favorable effect of local botulinum toxin A injections in patients with painful paraspinal muscle dystonia related to neurological disease or chronic low back pain. CONCLUSION: Botulinum toxin A may be a useful treatment for incapacitating painful dystonia of the paraspinal muscles. This treatment improves posture in the sitting position and facilitates the fitting of orthotic devices. Furthermore, botulinum toxin A treatment may help to determine whether an intrathecal baclofen test is in order. 相似文献

This study compared bilateral paraspinal excitation in normal subjects and subjects with low back pain. Comparison was made between six control subjects and seven low back pain subjects who performed maximum-effort isometric trunk extension in minimum elapsed time at two trunk angles. Electromyographic signals were collected bilaterally from the paraspinal musculature. The time- and amplitude-normalized electromyographic data were analyzed using a repeatability criterion sensitive to temporal and amplitude differences. This analysis showed that low back pain subjects demonstrated temporal and amplitude decoupling of the paraspinal musculature bilaterally. Low back pain subjects also demonstrated clinically meaningful disruptions between paraspinal excitation and isometric trunk extension moment. This method may be useful in quantifying neuromotor control in low back pain for initial and follow-up clinical evaluation for static and dynamic functional tests. 相似文献

Patterns of muscular activity during movement in patients with chronic low-back pain 总被引:5,自引:0,他引:5
Bilateral paraspinal electromyogram (EMG) at levels L1-L2 and L4-L5, and abdominal EMG of a group of 20 low-back pain patients were compared to those of a group of 20 pain-free controls during flexion, extension, lateral bending to right and left, and rotation to right and left. The results showed no significant left-right differences in paraspinal EMG levels between low-back pain patients and pain-free controls during any of the movements. However, patterns of paraspinal and abdominal EMG were found to be different for low-back pain patients compared to pain-free controls during flexion only. 相似文献

A retrospective analysis was performed in a nine month period of the electrophysiological data, imaging and clinical findings
of patients with monoradicular disc herniation compressing either the L5 or the S1 nerve root. The primary purpose of the
analysis was to determine the distribution of pathological spontaneous activity in the medial paraspinal muscles on electromyographic
examination in monoradicular L5 and S1 nerve root compression syndromes. Anatomically, the medial paraspinal muscles receive
their innervation from a single root while the iliocostalis muscles and the longissimus muscle are thought to be innervated
by multiple nerve roots. In the analysis, in single nerve root lesion of the L5 or S1 nerve root, electromyography of the
medial paraspinal muscles revealed pathological spontaneous activity one to three vertebrae cranial to the disc herniation
with extension to the opposite side of the lesion. In conclusion, the medial paraspinal muscles might be thought to be innervated
by one single nerve root on anatomical studies, electrophysiologically the extension of axonal lesion signs of one single
lumbar nerve root is much broader. The widespread distribution of the L5 and S1 nerve root must be taken into consideration
on electromyographic examination of the medial paraspinal muscles. 相似文献

PurposeNumerous studies have applied a variety of methods to assess paraspinal muscle degeneration. However, the methodological differences in imaging evaluation may lead to imprecise or inconsistent results. This article aimed to provide a pragmatic summary review of the current imaging modalities, measurement protocols, and imaging parameters in the evaluation of paraspinal muscle fat infiltration (FI) in MRI studies.MethodsWeb of Science, EMBASE, and PubMed were searched from January 2005 to March 2020 to identify studies that examined the FI of paraspinal muscles on MRI among patients with lumbar degenerative diseases.ResultsIntramyocellular lipids measured by magnetic resonance spectroscopy and FI measured by chemical‐shift MRI were both correlated to low back pain and several degenerative lumbar diseases, whereas results on the relationship between FI and degenerative lumbar pathologies using conventional MRI were conflicting. Multi‐segment measurement of FI at the lesion segment and adjacent segments could be a prognostic indicator for lumbar surgery. Most studies adopted the center of the intervertebral disc or endplate as the level of slice to evaluate the FI. Compared with visual semiquantitative assessment, quantitative parameters appeared to be precise for eliminating individual or modality differences. It has been demonstrated that fat CSA/total CSA (based on area) and muscle–fat index (based on signal intensity) as quantitative FI parameters are associated with multiple lumbar diseases and clinical outcomes after surgery.ConclusionHaving a good command of the methodology of paraspinal muscle FI on MRI was effective for diagnosis and prognosis in clinical practice. 相似文献

The purpose of this study was to systematically review the available evidence on lumbar paraspinal compartment syndrome with specific reference to patient demographics, aetiology, types, diagnosis, clinical features, and treatment. This was an Institutional Review Board-exempt study performed at a Level 1 trauma center. A PubMed search was conducted with the title query: lumbar paraspinal compartment syndrome. Eleven articles met our search criteria. Three of the patients with acute paraspinal compartmental syndrome treated with fasciotomy had a full recovery and were able to resume skiing after four months. The aetiology of the onset of lumbar paraspinal compartment syndrome is broadly divided into acute and chronic. Lumbar paraspinal compartment syndrome is one of the causes of back pain with diagnostic clinical features which should be considered in the differential diagnosis of a patient with low back pain. Prospective multicentre trials may provide the surgeon with more insight into the diagnosis and management of lumbar paraspinal compartment syndrome. 相似文献

BACKGROUNDA bacterial cause of disc degeneration has evoked several controversies and, if true, would lead to a major shift in treatment paradigm. Earlier studies analyzing the relationship of bacterial disc infection within a degenerative cohort featured prolonged cultures susceptible to contamination. The degenerate-disc infection study with contaminant control (DISC) trial aims to investigate this theory further by examining infection rates using a non-degenerative control cohort in comparison to a degenerative internal control cohort and a sham cohort (sampling only sterile paraspinal tissue). To our knowledge, the current study is the largest evaluating the growth of organisms (or possible contamination rate) in paraspinal tissue if prolonged cultures are performed. Protocols on methodology have been previously published.PURPOSE(1) To investigate the infection rates across cohorts (degenerative vs. nondegenerative control; paraspinal and/or disc controls vs. combined sampling cohorts) using stringent standardized aseptic surgical technique and laboratory processing. (2) To compare our findings to that of the literature and make a statement in support and/or against a possible contamination theory to positive cultures.STUDY DESIGNMulticenter, multisurgeon case-control trial.PATIENT SAMPLEIn all, 812 surgical samples were retrieved across a 3.5-year period (2013–2016) including 25 trauma controls (nondegenerative), 550 "disc and paraspinal” samples (degenerative cases with internal control), 190 disc-only samples (degenerative cases without internal control), and 46 paraspinal only controls (sham group).OUTCOME MEASURESGrowth and/or Contamination rate (%) per cohort. Chi-square of growth in disc versus paraspinal samples as a means of examining the distribution of false positive and contaminant growth. The impact of previous injections and/or surgery on positive disc or paraspinal growth. Correlation of Modic changes with positive growth rates analyzed with the Kruskal-Wallis Test. The distribution of species in positive samples were also analyzed.METHODSThe DISC trial is registered under Australian and New Zealand clinical trials registry—ACTRN12616000541404. Institutional ethics review was obtained (HREC northern sector 13/218) at the primary center and further centers (n=6) were recruited. Patients undergoing spinal surgery with discectomy were eligible for trial entry with tissue specimens obtained using strict aseptic technique for microbiological examination. All specimens were handled with sterile instruments only and by a fresh instrument to a sterile pot that was closed immediately. Separate pots were used for the disc and paraspinal tissue respectively with similar stringent processing during microbiological assessment. A cohort of the degenerative cases at one single institution also underwent an additional histopathological examination.RESULTSThere was an expected significant difference in gender and age associated with the non-degenerative control group (due to trauma patients) compared with other cohorts. There was a higher percentage of positive-growth in the control group in comparison to the disc and paraspinal and disc only groups across positive disc growth (48% vs. 27% vs. 17%, p<.001). A similar infection rate was observed in the paraspinal samples across the equivalent controls (44% vs. 36% vs. 37%, p=.739). There was a significant difference in the proportions of positive growth with a large proportion of false positives (growth in both disc and paraspinal samples; p<.001). There was no difference in true positive growth between the case and control groups (16.0 vs. 7.7%, p=.112). These trends were preserved across all cohorts and when stratifying by spinal segment (cervical or lumbar). There was no correlation between Modic changes and positive disc culture growth (p=.398, n=144 samples). Cutibacterium (formerly Propionibacterium) acnes was the most dominant pathogen isolated, representing between 50% and 70% of positive disc and paraspinal specimens, followed by staphylococcal species.CONCLUSIONSOur study failed to find a difference in true infection rates between the nondegenerative and degenerative disc populations. These findings are suggestive of a contamination theory and against a common infective etiology in the setting of discogenic back and neck pain. We believe the rationale for antibiotic therapy in the management of discogenic back pain warrants further evidence to establish efficacy. 相似文献

BACKGROUND AND OBJECTIVES: The concept of radiofrequency denervation has recently come under question in light of several studies showing minimal to no benefit. One possibility proposed for these negative outcomes is poor selection criteria. Unlike virtually all other spine interventions, the factors associated with success and failure for cervical facet denervation have yet to be determined. The purpose of this study is to determine which demographic, clinical and treatment factors are associated with cervical facet radiofrequency denervation outcomes. METHODS: Data were garnered from 3 academic medical centers on 92 patients with chronic neck pain who underwent radiofrequency denervation after a positive response to diagnostic local anesthetic blocks. Success was defined as at least 50% pain relief lasting at least 6 months. Variables evaluated for their association with outcome included age, sex, duration of pain, opioid use, pain referral pattern, paraspinal tenderness, pain exacerbated by extension/rotation, magnetic resonance image abnormalities, diabetes, smoking, scoliosis, obesity, prior surgery, and levels treated. RESULTS: The only clinical variable associated with success was paraspinal tenderness. Factors associated with treatment failure included radiation to the head, opioid use, and pain exacerbated by neck extension and/or rotation. CONCLUSIONS: Selecting patients based on key clinical variables may increase the chance of treatment success for cervical facet radiofrequency denervation. 相似文献

IntroductionLow back pain is one of the most common cause for outpatient visits. Though few studies have shown the vital role of paraspinal muscles in lumbar spine pathology, literature is scarce regarding the influence of the paraspinal muscles in disc degeneration. We aimed to analyse the correlation between paraspinal muscles and disc degeneration.MethodsThis is a Level III Prospective Cohort Study done in MRI of lumbosacral spine in 504 patients at 2520 levels from L1-2 to L5-S1. The parameters assessed were age, Pfirrmann grade for disc degeneration and paraspinal muscle (Multifidus and Erector Spinae) mass assessed by the gross cross sectional area of the muscle.The values and their correlation was analyzed using SPSS software.ResultsThe study included a total of 504 patients (231 males and 273 females) with a mean age of 52.00 ± 15.00 (22–80) years. The mean GCSA in cm2 of the paraspinal muscles at L1-L2, L2-L3,L3-L4,L4-L5,L5-S1 were 16.177 ± 2.72, 17.275 ± 2.16, 16.900 ± 3.07, 16.800 ± 2.63, 13.426 ± 2.42 respectively. We found that the age of the patient is directly proportional to the disc degeneration and inversely proportional to GCSA of paraspinal muscle. There was a significant negative correlation between disc degeneration and paraspinal muscle mass.ConclusionWe found that the paraspinal muscle mass reduces and Pfirrman's Grade increases as age advances. Also patients with disc degeneration tend to have wasting of paraspinal muscles and vice versa. Hence, strengthening the paraspinal muscles should be emphasised to prevent back pain and to stall the degeneration cascade. 相似文献

BACKGROUND CONTEXT: Despite clinical evidence for the benefits of spinal manipulation and the apparent wide usage of it, the biological mechanisms underlying the effects of spinal manipulation are not known. Although this does not negate the clinical effects of spinal manipulation, it hinders acceptance by the wider scientific and health-care communities and hinders rational strategies for improving the delivery of spinal manipulation. PURPOSE: The purpose of this review article is to examine the neurophysiological basis for the effects of spinal manipulation. STUDY DESIGN: A review article discussing primarily basic science literature and clinically oriented basic science studies. METHODS: This review article draws primarily from the peer-reviewed literature available on Medline. Several textbook publications and reports are referenced. A theoretical model is presented describing the relationships between spinal manipulation, segmental biomechanics, the nervous system and end-organ physiology. Experimental data for these relationships are presented. RESULTS: Biomechanical changes caused by spinal manipulation are thought to have physiological consequences by means of their effects on the inflow of sensory information to the central nervous system. Muscle spindle afferents and Golgi tendon organ afferents are stimulated by spinal manipulation. Smaller-diameter sensory nerve fibers are likely activated, although this has not been demonstrated directly. Mechanical and chemical changes in the intervertebral foramen caused by a herniated intervertebral disc can affect the dorsal roots and dorsal root ganglia, but it is not known if spinal manipulation directly affects these changes. Individuals with herniated lumbar discs have shown clinical improvement in response to spinal manipulation. The phenomenon of central facilitation is known to increase the receptive field of central neurons, enabling either subthreshold or innocuous stimuli access to central pain pathways. Numerous studies show that spinal manipulation increases pain tolerance or its threshold. One mechanism underlying the effects of spinal manipulation may, therefore, be the manipulation's ability to alter central sensory processing by removing subthreshold mechanical or chemical stimuli from paraspinal tissues. Spinal manipulation is also thought to affect reflex neural outputs to both muscle and visceral organs. Substantial evidence demonstrates that spinal manipulation evokes paraspinal muscle reflexes and alters motoneuron excitability. The effects of spinal manipulation on these somatosomatic reflexes may be quite complex, producing excitatory and inhibitory effects. Whereas substantial information also shows that sensory input, especially noxious input, from paraspinal tissues can reflexively elicit sympathetic nerve activity, knowledge about spinal manipulation's effects on these reflexes and on end-organ function is more limited. CONCLUSIONS: A theoretical framework exists from which hypotheses about the neurophysiological effects of spinal manipulation can be developed. An experimental body of evidence exists indicating that spinal manipulation impacts primary afferent neurons from paraspinal tissues, the motor control system and pain processing. Experimental work in this area is warranted and should be encouraged to help better understand mechanisms underlying the therapeutic scope of spinal manipulation. 相似文献

Summary This study of 52 patients (27 men) with recent (18 months) or chronic (>18 months) low back and unilateral radicular pain symptoms was undertaken to investigate whether wasting of the paraspinal muscle components is generalised or selective. During the patients' routine computed tomographic lumbar spinal scans a standardised transaxial view was obtained along the upper end-plate of the L4 vertebra, and the cross-sectional areas of the paraspinal muscles and their components, multifidus and erector spinae, estimated. Irrespective of whether the symptoms were recent or chronic, multifidus dimensions were significantly greater on the side ipsilateral to the radicular pain symptoms. The results indicate selective changes of multifidus in these patients and possibly reflect an adaptive response by this muscle, such as to an increased role in stabilising the lumbar spine in the face of overall paraspinal muscle atrophy.

OBJECTIVE AND IMPORTANCE: Sclerosing epithelioid fibrosarcoma (SEF) is a rare mesenchymal neoplasm composed of rounded, vimentin-immunoreactive tumor cells disposed in nests and cords within a hyalinized collagenous matrix. Most examples arise in the deep skeletal muscles of adults. The cases recorded to date have been characterized by protracted clinical evolutions with a tendency for stubborn local recurrence, followed by late metastasis. Accordingly, SEF has been regarded as a low-grade sarcoma. A single instance of brain and vertebral metastasis has been described. We report three examples of SEF distinguished by primary involvement of the neuraxis at initial presentation. CLINICAL PRESENTATION: Two tumors had intracranial, calvarial and extracalvarial, soft-tissue components, whereas the third tumor manifested as a paraspinal mass with extension into the T12-L1 neural foramen and invasion of the T12 nerve root. INTERVENTION: All three affected patients experienced local recurrence and distant metastasis after resection of the primary site. These complications appeared early in the disease course in two cases. In no case was there a response to adjuvant chemotherapy or radiotherapy. CONCLUSION: Our experience indicates that SEFs arising along the neuraxis may demonstrate unexpectedly aggressive clinical behavior, compared with those arising in the more typical location of deep skeletal muscles. 相似文献

Low back pain often represents the first sign of a lumbar metastasis from a primary unknown tumor. In 13 cases who came to
our observation, a unifocal metastasis was detected. All the patients underwent biopsy directed by computed tomography. The
8 patients who showed vertebral instability and radicular involvement underwent surgical treatment. The prognosis in cases
of unifocal lumbar metastasis is related to the kind of primary tumor. Surgical treatment plays an important role in achieving
pain relief and in improving life quality. Conservative care must be reserved for metastatic localizations from primary cancers
that are sensitive to chemiotherapy or radiation therapy in patients without vertebral instability and neurological signs.

Context: Approximately 25% of all primary spinal cord tumors are meningiomas, and 80% of these tumors occur in the thoracic region. Few meningiomas of the lumbar spine have been presented. Extracranial metastasis of meningioma occurs extremely rare, only in about 0.1% of meningiomas. Even metastasis, the sites are seldom seen in deep soft tissue. We reported a woman original meningioma in the lumbar spine with distal deep neck metastasis.Findings: A 59-year-old patient suffered from severe right drop foot, numbness, and radicular pain for the previous 6 months. Computed tomography (CT) disclosed a huge, macrolobulated retroperitoneal soft-tissue lesion with a size of 14.9 × 10.8 × 17.7 cm. Magnetic resonance imaging (MRI) further revealed a solid spinal intracanal tumor with moderate enhancement involving the right paraspinal region at the L2∼L5 level and the right iliac fossa. A meningioma was diagnosed with histological proof. Four months later, another metastatic meningioma in her left neck. She was managed conservatively without neurologic dysfunction.Conclusions: To the best of our knowledge, such a large meningioma of the lumbar spine has not previously been reported in the literature. In this study, we demonstrated a rare spinal meningioma located in the lumbar spine primarily with secondary soft tissue metastasis. 相似文献
