Sensitivity of Laségue Sign and Slump Test in Hernia and Disc Bulging Diagnoses Compared with Magnetic Resonance Imaging / Sensibilidade das manobras de Laségue e de slump nos diagnósticos de hérnia e abaulamento discal em comparação com ressonância magnética

Abstract Objective To show the accuracy of the most used maneuvers in the clinical diagnosis of lumbosciatalgia, the slump test and the Laségue sign. Methods In order to perform the present study, 101 patients with magnetic resonance imaging (MRI) discopathy (gold standard) were selected and had their medical records reviewed to identify which had the positive maneuvers on the initial physical examination. Results The sensitivity found for the slump test and the Laségue sign in the diagnosis of disc herniation was 55.3% and 18.1%, respectively. Nonetheless, when they were compared with each other for the diagnosis of disc bulging, the sensitivity obtained was of 85.7% for the slump test and of 28.6% for the Laségue sign. Conclusion Comparing both clinical exams with MRI, it was found that the slump test presents superior sensitivity compared with the Laségue sign for both the diagnosis of hernia and disc bulging, and should be more present in clinical practice.

Resumo Objetivo Mostrar a acurácia das manobras mais usadas no diagnóstico clínico da lombociatalgia, a manobra de slump ea de Laségue. Métodos Para a realização do presente estudo, foram selecionados 101 pacientes com discopatia na ressonância magnética (RM) (padrão ouro), sendo posteriormente realizada a revisão dos prontuários para identificar quais tiveram as manobras positivas no exame físico inicial. Resultados A sensibilidade encontrada para as manobras de slump e Laségue no diagnóstico de hérnia discal foi respectivamente 55,3% e 18,1%. Já quando comparamos as manobras para o diagnóstico de abaulamento discal, a sensibilidade obtida foi de 85,7% para a manobra de slump e de 28,6% para a manobra de Laségue. Conclusão Foi constatado que a manobra de slump apresenta sensibilidade superior à da manobra de Laségue tanto para o diagnóstico de hérnia quanto para o de abaulamento discal quando comparadas a RM, e deveria estar mais presente na prática clínica.

Radiofrecuencia pulsada del ganglio de la raíz dorsal en un caso de sindrome radicular lumbosacro crónico refractario a los esteroides epidurales / Pulsed radiofrequency of dorsal root glanglion a clinical case of chronic lumbosacro syndrome refractory to epidural steroids

Las inyecciones epidurales de esteroides son frecuentemente indicadas en el sindrome radicular lumbosacro, producido por hernias de disco, protrusiones discales o estenosis del canal, cuando éste no responde al tratamiento no intervencionista. Sin embargo, por distintas causas, aproximadamente 20% de los pacientes no responden a estas inyecciones, quedando pocas opciones terapéuticas disponibles. La radiofrecuencia pulsada del Ganglio de la Raíz Dorsal de las raíces afectadas es una alternativa válida para tratar el sindrome cuando es refractario al tratamiento con inyecciones epidurales de esteroides, en caso de que la cirugía de columna no está indicada o se prefiera evitar. Se presenta un caso clínico de un sindrome radicular lumbosacro refractario, causado por protrusiones discales lumbares, donde se utilizó la radiofrecuencia pulsada del ganglio de la raíz dorsal con buenos resultados, evaluados mediante el Inventario Abreviado del Dolor (Brief Pain Inventory).

Lumbosacral radicular syndrome, produced by discs herniations, discs protrusions or spinal stenosis is frequently treated by injecting steroids in the epidural space. However, 20% of the patients are resistant to this treatment, so few therapeutics options for them are left. Pulsed radiofrequency of the Dorsal Root Ganglion is a validated therapeutic option, when the syndrome is refractory to epidural steroid injections and spinal surgery is not indicated or elected. We report a clinical case of a lumbosacral radicular syndrome, refractory to epidural steroid injections, successfully treated with pulsed radiofrequency of lumbar Dorsal Root Ganglion, utilizing the Spanish version of the Brief Pain Inventory, as an outcome evaluation tool.

Can lumbar hemorrhagic synovial cyst cause acute radicular compression? Case report / O cisto sinovial hemorrágico lombar pode causar compressão radicular aguda? Relato de caso

Lumbar synovial cysts are an uncommon cause of back pain and radiculopathy, usually manifesting with gradual onset of symptoms, secondary to involvement of the spinal canal. Rarely, intracyst hemorrhage occurs, and may acutely present as radicular - or even spinal cord - compression syndrome. Synovial cysts are generally associated with degenerative facets, although the pathogenesis has not been entirely established. We report a case of bleeding complication in a synovial cyst at L2-L3, adjacent to the right interfacet joint, causing acute pain and radiculopathy in a patient on anticoagulation therapy who required surgical resection.

Cistos sinoviais da coluna lombar são uma causa incomum de dor na coluna e radiculopatia, geralmente com evolução gradual dos sintomas, que são secundários ao comprometimento do canal vertebral. Raramente, há hemorragia intracística, que pode se manifestar de forma aguda com síndrome compressiva radicular ou mesmo medular. Habitualmente, os cistos sinoviais associam-se a doença degenerativa facetária, embora a patogênese não esteja completamente estabelecida. Relatamos aqui um caso em que uma complicação hemorrágica em um cisto sinovial no nível L2-L3, adjacente à interfacetária direita, causou dor lombar e radiculopatia em um paciente em terapia anticoagulante, sendo necessária a ressecção cirúrgica.

Evaluation of arthrodesis and cervical alignment in the surgical results of cervical discectomy using polymethylmetacrylate / Avaliação da artrodese e do alinhamento cervical após discectomia cervical com interposição de polimetilmetacrilato

BACKGROUND AND OBJECTIVES: Surgical treatment of cervical radiculopathy with or without myelopathy is a controversy issue, although anterior discectomy is the most common form of treatment. METHOD: We present the evaluation of the arthrodesis' rate and cervical alignment in 48 patients with cervical degenerative disease (CDD) submitted to anterior cervical discectomy with interposition of polymethylmetacrylate (PMMA). Odom and Nürick scales were used to evaluation of functional status before and after surgery. Cervical spine X-rays were used to access arthrodesis and alignment, at least 2 years after the procedure. RESULTS: Excellent and good results (Odom I and II) were obtained in 91 percent of the patients with radiculopathy and in 69 percent of those with myelopathy. Using the chi square test of independence (1 percent of significance), there was no association between excellent and good clinical results with the presence of arthrodesis verified in cervical X-rays. The presence of cervical alignment had association with good results, whereas the misalignment was associated with unfavorable outcomes. Two patients died: one cervical hematoma and other from graft migration with cord compression. CONCLUSIONS: Cervical alignment was more important than fusion to achieve good surgical results in CDD.

TEMA E OBJETIVO: O tratamento cirúrgico da radiculopatia cervical com ou sem mielopatia é um tema controverso, embora a discectomia por via anterior seja uma das formas mais comuns de tratamento. MÉTODO: Apresentamos a avaliação da artrodese cervical e do alinhamento pós operatório em 48 pacientes com doença degenerativa cervical (DDC) submetidos a discectomia por via anterior seguida da interposição de polimetilmetacrilato (PMMA). As escalas de Odom e de Nurick foram utilizadas para avaliar o status funcional dos pacientes antes e após a cirurgia. Radiografias da coluna cervical foram utilizadas para avaliar a artrodese e o alinhamento cervical, pelo menos 2 anos após o procedimento. RESULTADOS: Excelentes e bons resultados (Odom I e II) foram obtidos em 91 por cento dos casos com radiculopatia e em 69 por cento dos pacientes com mielopatia. Usando o teste do qui-quadrado de independência (1 por cento de significância), não houve associação entre os resultados excelentes e bons e a presença de artrodese. A presença de alinhamento cervical, ao contrário, correlacionou-se com bons resultados. Dois pacientes faleceram devido a hematoma cervical e migração do enxerto. CONCLUSÃO: O alinhamento cervical correlacionou-se com bons resultados cirúrgicos em nossos pacientes, enquanto que a taxa de artrodese não teve relação com o resultado clínico dos pacientes.

Síndrome de dolor inguinal crónico (SDIC) / Chronic inguinal pain syndrome

Background: Chronic inguinal pain syndrome (CIPS) is a frequent complaint in patents attending to a public ambulatory surgical service. Aim: To report a descriptive observational study of CIPS. Material and Methods: Retrospective review of medical records of patients presenting with CIPS between 1999 and 2006. The symptoms and physical examination of the groin, the spine and the coxofemoral joint of these patients was evaluated. Results: CIPS was diagnosed in 150 patients aged 17 to 71 years, 87 men. They represented 14 percent of groin problems diagnosed in the study period. Median duration of pain was 13 (3-150) months, with remissions that lasted from weeks to months. The charactenstics of pain remained constant in each remission. Pain was present during the daily activities, but it was even worse during resting periods and during night sleep, leading the patient to assume pain reducing positions. Hernia was present in 29 patients and occupied inguinal channel in three. Five patients had a history of previous hernia repair. One hundred twenty patients had spine diseases. An anesthetic blockade of the ilioinguinal nerve was performed in 37 patients with a positive response in seven. Twenty nine of 47 groin ultrasound examinations were informed as abnormal and suggestive of inguinal hernia. Surgical treatment was performed in these patients and was associated with pain abolition in 12, reduction in seven and persistence in the rest. Remaining patients were treated with spine rehabilitation. The short time follow-up of both groups was encouraging. Conclusions: Inguinal hernia and radicular pain due to spine problems are the main causes of CIPS in this series of patients.

El Síndrome de Dolor Inguinal Crónico (SDIC) ha sido un hallazgo frecuente en el Centro de Cirugía Mayor Ambulatoria de las Hernias del CRS Cordillera. Presentamos un estudio observacional descriptivo del SDIC, basado en la información contenida en las fichas clínicas en un período de 7 años. Se estudiaron los síntomas, el examen físico de la región inguinal, de la columna vertebral, de la inervación de la zona y de la articulación coxofemoral. El cuadro clínico afectó a 150 pacientes, 87 varones y 63 mujeres, con una edad promedio de 42 años (17-71). La antigüedad de los síntomas fue en promedio de 13 (3-150) meses apreciándose remisiones de duración variable, de semanas o meses, sin variación de las características neuropáticas del dolor. Si bien éste se presentó durante la actividad, estuvo presente también en el reposo sentado y el nocturno aliviándose con posición antálgica. Se detectó una hernia inguinal en 29, un canal inguinal ocupado en 3 y antecedente de herniorrafia en 5 pacientes. En los restantes 129 pacientes se detectó patología de columna vertebral, apreciándose en todos un examen neurológico alterado. El bloqueo del nervio ilioinguinal se efectuó en 37 pacientes siendo positivo en 7. La ecotomografía de partes blandas de la región inguinal adquiere valor sólo en manos experimentadas. Una operación se realizó ante evidencia de patología inguinal, los demás pacientes fueron sometidos a rehabilitación de la columna vertebral. Los resultados a corto plazo han sido satisfactorios en ambos grupos.
