Full textThe system of vertebrae fixation using the pedicular screw is one of the most efficient methods to treat vertebral spine pathologies. When the screw is submitted to pullout strength, it causes internal stress near the medullary canal and this situation can be analyzed using the photoelasticity technique. The objective of this study was to examine the internal stress of a photoelastic vertebrae model using different sizes of screws for the vertebral fixation submitted to pulling out. A lumbar vertebral model made of photoelastic material with three different pedicular screw sizes (5, 6 and 7mm), type USS1 was used. The internal stress around the screw were tested in 18 pre established points by a plain transmission polariscope. The areas of greater concentration of stress were placed between the medullary canal and the transverse process. Comparing the maximum average pulling out stress, statistical differences were observed between screws 5 and 7, and 6 and 7. On the other hand, when screws 5 and 6mm where compared no significant differences were found. This study identified that the internal stress are greater in irregular areas, near the medullary canal, suggesting that this may be a critical region.

Resumo: Existe uma grande variabilidade de resultados nos estudos prévios que analisam os parâmetros do alinhamento sagital (PAS) em indivíduos normais e em pacientes com doenças degenerativas da coluna lombar. A maioria desses estudos relacionam os PAS somente com o sintoma de dor lombar crônica, em grupos de pacientes com diferentes doenças degenerativas lombares, o que dificulta a aplicação clínica desses dados tanto na avaliação diagnóstica como na indicação terapêutica. O objetivo deste estudo caso-controle foi analisar as relações dos PAS com os diferentes sintomas entre um grupo de pacientes com diagnóstico de estenose lombar e um grupo controle e as mesmas relações entre os subgrupos de pacientes diferenciados por sintoma. Foram colhidos os dados da história, exame clínico, ressonância magnética e de exames radiográficos de 23 pacientes com estenose lombar (denominado grupo estenose) e de 17 indivíduos saudáveis (denominado grupo controle). Os PAS utilizados foram: cifose torácica (CT), lordose lombar (LL), eixo sagital vertical (C7-T1), listese anteroposterior (OAP), lordose lombo-pélvica total (LLT) e regional (LLR), eixo sagital em T1, T4 eT9 (ES1, ES4 e ES9 respectivamente), inclinação sagital T1-L5 (IST1-L5), "offset sagital" T1 e T9 (OST1 e OST9), "tilt pélvico" (TP), "slope sacral" (SS), morfologia pélvica (MP), ângulo sacro-femoral (ASF), distância sacro-femoral (DSF) e "overhang" (OVHG). Na Fase 1 do estudo, os dados do PAS foram correlacionados entre os indivíduos do grupo controle e grupo estenose e, na Fase 2, entre os subgrupos do grupo estenose diferenciados por sintomas como lombalgia, radiculopatia, claudicação neurogênica e dor, medida pela Escala Analógica de Dor (EAD). Na Fase 1, observou-se que os pacientes do Grupo Estenose (GE) como um todo tiveram menores valores de LLT (p = 0,006) e LLR em L1, L2 e L3 (p = 0,026) e os pacientes do GE com sintoma de radiculopatia, além dos dados acima, tiveram aumento do TP (p = 0,004), quando comparados ao Grupo Controle (GC). Na Fase 2, o Subgrupo Lombalgia obteve maiores valores de CT (p = 0,035) e LLR (p = 0,028) e uma diminuição do TP (p = 0,029), OST1 (p = 0,022), DSF (p = 0,014) e OVHG (p = 0,035) em relação aos outros pacientes do GE que não se queixavam de lombalgia e, no Subgrupo Radiculopatia, houve a diminuição da LLR (p < 0,047). Este estudo demonstra que há correlações significativas dos sintomas e dos PAS entre o GE e o GC e também entre os Subgrupos do GE diferenciados por sintomas. Estes dados indicam uma melhor interpretação clínica dos PAS, assim como podem sugerir a terapêutica mais adequada
Abstract: There is a great variation in the results of previous studies analyzing sagital alignment parameters (SAP) in normal individuals and in patients with degenerative diseases of the lumbar spine. Most studies associate SAP only with chronic lumbar pain, in groups of patients with different lumbar degenerative diseases, which makes it difficult to apply these data clinically both in diagnostic evaluation and in therapeutics. The objective of this prospective, diagnostic case-control study was to examine the relationship between sagittal balance parameters and different symptoms of spine disease in patients with lumbar canal stenosis (LCS) and controls and the same associations between subgroups of patients with different symptoms. We collected clinical history, clinical exam data from 23 patients with spinal stenosis and 17 healthy volunteers (controls). Magnetic resonance imaging (MRI) and x-rays allowed the measurement of sagittal axis parameters. The SAP analyzed were thoracic kyphosis, lumbar lordosis, sagittal axis, anterior-posterior listesis, total and regional lumbar-pelvic lordosis, sagittal axis in T1, T4 and T9, pelvic tilt, sacral slope, pelvic morphology, sacro-femoral angle, sacro-femoral distance and overhang. In the first phase of the study, SAP data were correlated between controls and patients, and in the second phase, the subgroups inside the group of patients with stenosis were compared for symptoms as lumbar pain, radiculopathy, neurogenic claudication and pain, measure by the visual analogue scale (VAS). In the first phase, it was observed that the stenosis patients presented lower values of total lumbopelvic lordosis (p = 0.006) and regional lordosis L1, L2 and L3 (p < 0.026). Those with stenosis and radiculopathy also had higher values of pelvic tilt (p = 0.004) and lower values for total lumbopelvic lordosis and regional lordosis in L1 and L2 (p < 0.05) than controls. All patients complaining of back pain had higher values of thoracic kyphosis (p = 0.035), regional lumbopelvic lordosis in L1 (p = 0.028), lower values for pelvic tilt (p = 0.029), sagittal T1 offset (p = 0.022), sacro-femoral distance (p = 0.014) and overhang (p = 0.035) compared to patients without the complaint. Patients with stenosis and radiculopathy were less prone to have regional lordosis in L2, L3 and L4 (p = 0.047, p = 0.047 and p = 0.023 respectively). In conclusion, this study shows that there are significant correlations between symptoms and sagittal axis parameters between patients with and without spinal canal stenosis and also in subgroups of the patients with stenosis with different complaints.These data indicate a better clinical interpretation of SAP, as well as suggest a better therapeutic approach

Full textThe vertebral bodies and intervertebral discs participation in lumbar lordosis and their contribution between lumbar curves of different size were studied. 350 lumbar spine radiographs of asymptomatic adults (143 men and 207 women, average age 29 years) were evaluated. Lumbosacral (L1S1) and lumbolumbar (L1L5) curves and the angular inclination of each vertebral boby and intervertebral disc were measured using a Cobb method variant. The percentile participation of each vertebral body and intervertebral disc in the lumbossacal curve was calculated. Sex and age were compared. The subjects were separated in tree subgroups, in acording to lumbosacral curve size. The compounds of lumbar curve (discs and vertebrae) were compared in these tree subgroups. The mean lumbosacral curve was ?60,9º (-33º to ?89º). L1 vertebral body was kyphotic (2,15º), L2 was neutral (-0,36º), and the other ones were progressively lordotic from L3 (-1,56º) to L5 (-9,23º). The intervertebral discs were progressively lordotic from L1-L2 (?4,99º) to L5-S1 (?15,58º). Both vertebrae and discs showed a progressive participation in cephalic-caudal direction. The participation of discs was about 80% of lumbosacral curve, and the caudal elements (L4, L5 vertebrae and L4-L5, L5-S1 discs) contributed far 65% of the curve. The older subjects presented lumbar curves larger than younger 4º average, with significant statistical difference to L2, L5 and L3-L4 measures, with older subjects presenting bigger angular values. There were statistical differences of lumbar curves, L2 and L4 measures between sexes, with females presenting bigger values. The lumbosacral curve presented average -46,9º in minor lordosis subgroup, -64,59º in intermediate lordosis sugbroup, and ?74,13º in major lordosis subgroup. The lumbolumbar curve presented average ?33,28º in minor lordosis subgroup, -45,34º in intermediate lordosis subgroup, and ?56,96º in major lordosis subgroup. The absolut values of vertebrae and discs angles were smaller in minor lordosis subgroup than in major lordosis subgroup, but the intervertebral discs participation of was bigger in minor lordosis subgroup (88%) than intermediate lordosis (81%) and major lordosis (75%) subgroups. Complementarely, the vertebrae had a bigger participation in intermediate and major lordosis subgroups. Individually, the vertebrae presented a larger participation in major lordosis subgroup, excepting L5 that presented bigger participation in minor lordosis subgroup. The discs presented larger participation in minor lordosis subgroup. That is consequence of a more kyphotic inclination of the cephalic vertebrae in minor lordosis subgroup than the other ones, causing a compensating effect, with a larger disc participation in the small curves. The intermediate and major lordosis subgroups had the cephalic vertebrae more lordotic than that of the minor lordosis subgroup. We concluded that the intervertebral discs are the main responsible for the lumbar curve angulation and that the contribution of vertebrae and discs in lumbar curves of different sizes is not equal. In spite of a gradual increase of lordotic wedging while lumbar curve increase, the cephalic vertebrae make the disc and vertebrae participation different between different magnitude lumbar curves.

Full textO estudo dos nervos constituintes do plexo lombossacral é de extrema importância, pois relaciona os diversos aspectos evolutivos de postura e locomoção dos animais. Considerando-se que o nervo femoral é o maior da parte cranial do plexo lombossacral, objetivou-se descrever as origens, distribuições e ramificações dos nervos femorais no Tamanduá bandeira (Myrmecophaga tridactyla), comparando com a literatura descrita para animais domésticos e silvestres, de modo a estabelecer correlações de similaridades morfológicas e fornecer subsídios para as áreas afins. Foram utilizadas três espécimes, preparadas através da injeção de solução aquosa de formaldeído a 10% via artéria femoral, para a conservação e posterior dissecação das mesmas. As origens nos antímeros direito e esquerdo, ocorreram dos ramos ventrais dos nervos espinhais lombares um, dois e três. As distribuições e ramificações foram observadas para os músculos psoas maior e menor, ilíacos lateral e medial, pectíneo, adutor magno, sartório e quadríceps femoral. Com base nas origens dos nervos femorais do M. tridactyla, uma reconfiguração foi observada devido à variação no número de vértebras lombares (L1, L2 e L3). Entretanto, uma similaridade morfológica parcial foi mantida quanto às distribuições e ramificações, quando comparadas aos animais domésticos e silvestres considerados neste estudo.

Resumo: Modelo de Estudo: Estudo diagnóstico Transversal de caso controle. Objetivos: comparar pacientes com estenose do canal lombar com indicação de cirurgia e um grupo controle, assintomáticos para esta doença, levando em consideração imagens de ressonância magnética (RM) e o questionário de Oswestry. Material e Método: Vinte e três pacientes com estenose do canal lombar foram comparados com um grupo controle de 17 indivíduos. Todos foram submetidos a RM e responderam ao questionário de Oswestry. Medidas qualitativas foram descritas segundo os grupos com uso de frequências absolutas e relativas e, verificada a existência de associação dessas medidas com uso do teste exato de Fisher. Medidas quantitativas foram descritas e comparadas entre os grupos com uso do teste Mann-Whitney. O teste de Spearman foi utilizado para avaliar a correlação entre os grupos. Resultados: Lombalgia foi a queixa mais frequente nos dois grupos. O índice de Oswestry mostrou média de percentual de invalidez de 45,69% no Grupo Estenose e 11,60% no Grupo Controle. A RM mostrou que a área de secção transversa do saco dural, o diâmetro do canal e a avaliação dos forames e recesso lateral estavam alterados em ambos os grupos. Conclusões: Não houve relação entre o grau de estenose do canal lombar mensurado em exame de RM com o índice de Oswestry em ambos os grupos
Abstract: Study design: Transversal Case-control, diagnostic study. Objectives: To verify the relationship between the degree of lumbar spinal canal stenosis (LCS), as seen in magnetic resonance imaging (MRI), and the severity of disability as seen in the Oswestry Index, in patients with LCS compared to controls without a diagnosed LCS. Methods: Twenty-three patients with a previous diagnosis of LCS were compared with a control group of 17 volunteers. All participants underwent MRI and answered the Oswestry questionnaire. Qualitative data were described according to the groups with the use of absolute and relative frequencies, and the association of these measures was checked by using the Fisher exact test. Quantitative measures were described and compared between groups using the Mann-Whitney test. Spearman's test was used as well. Results: Low back pain was the most frequent complaint in both groups. The Oswestry index showed average percentage of disability of 45.69% in patients with stenosis and 11.60% in the control group. MRI revealed that the dural sac cross-sectional area (DCSA), the diameter of the canal and the evaluation of lateral recesses and foramina were equally changed in both groups. Conclusions: There was no correlation between the degree of lumbar canal stenosis measured on MRI with the Oswestry Disability Index in both groups
