    Full Text Available Objetivo: Describir una vía supracicatricial de abordaje y la técnica para la realización de epidurolisis, adhesiolisis y/o bloqueos repetidos radiculares, en síndromes dolorosos por atrapamiento nervioso cicatricial posterior a cirugías de columna lumbar, como alternativa a la epidurolisis caudal descrita en la literatura. Considerando que puede presentar menos complicaciones y puede presentar mejores resultados. Material y método: Ocho pacientes que presentan dolor posterior a cirugías de columna lumbar, con cuadros clínicos de lumbalgia, lumbociatalgia o ciática, con clínica y estudios de imagen (RNM, TAC, mieloTAC sugerentes de fibrosis epidural, estudios de EMG y PESS que indicaban daño en raíces lumbares igual o más que en raíces sacras. Los pacientes no presentaban patología asociada o contraindicaciones para la realización de la técnica. En todos los casos se utilizo: antibioterapia previa, sedación y monitorización del paciente. Se coloca al paciente en decúbito prono, con apoyo abdominal para reducir la lordosis fisiológica posicional y se localiza el espacio interespinoso inmediatamente superior a la cicatriz, para abordar el espacio epidural. Se localiza el espacio epidural con una aguja RX Coudé Curva 8,75 cm 15 g de Epimed® con el bisel orientado caudalmente, confirmando con escopia de alta resolución, mediante la inyección de 0,5 mL de contraste. Se introduce el catéter Tun-L-Kath Epimed® de 19 g y 84,5 cm y se orienta caudalmente hacia el nivel y el lugar con mayor sintomatología con control radiológico directo, hasta la parada en la progresión del catéter y se inyecta contraste para verificar el obstáculo, con la difusión retrógrada del mismo, producida por la fibrosis cicatricial. Se intenta progresar comprobando que al hacerlo hay reproducción de las sensaciones del dolor del paciente. Se extrae la aguja y se vigila la inmovilidad de la punta del catéter con control radiológico. Se tuneli

    Full Text Available El estudio de biomarcadores, o marcadores biológicos para el diagnóstico y seguimiento al tratamiento de enfermedades, constituye referente frecuente en la literatura científica biomédica actual. Se realizó una revisión bibliográfica empleando los recursos disponibles en la red Infomed, específicamente Ebsco, The Cochrane Librery, PubMed, Hinari y SciELO, a través de los cuales se accedieron a las bases de datos: MEDLINE, Academic Search Premier, MedicLatina y Scopus. Se recopilaron varios artículos científicos, donde se hace referencia al empleo de biomarcadores en el diagnóstico de enfermedades relacionadas con el sistema nervioso. El factor de crecimiento endotelial, la inmunoglobulina G (IgG y el sistema arginina - óxido nítrico - citrulina, se refieren como indicadores prematuros de la hemorragia subaracnoidea. La disminución del amiloide beta y el aumento de las concentraciones de proteína tau en el líquido cefalorraquídeo, se cuentan entre los biomarcadores más prometedores e informativos que indiquen precozmente el Alzheimer y otras enfermedades neurodegenerativas. Estos mismos marcadores se comportan de manera contraria a nivel plasmático. La copeptina es un biomarcador fácilmente medible, que refleja la situación de estrés a la que está sometido el organismo y se propone su uso en el diagnóstico del síndrome de Burnout; además, niveles aumentados de α-amilasa y cromogranina A (CgA salivales pueden también ser utilizadas como indicadores de este síndrome. Se logró recoger en este artículo un compendio de ejemplos de marcadores biológicos, utilizados en el diagnóstico de enfermedades relacionadas de alguna forma con el sistema nervioso

    Full Text Available La verdadera prevalencia del síndrome de atrapamiento de la arteria poplítea es desconocida; se estima en un 0.16%. Se considera la principal causa de claudicación intermitente en jóvenes deportistas sin factores de riesgo cardiovasculares. Se caracteriza por la compresión extrínseca de la arteria poplítea, ya sea por defecto anatómico de las estructuras músculo-tendinosas o por hipertrofia de los músculos gemelos, lo cual ocasiona el atrapamiento y síntomas de parestesias, frialdad y claudicación intermitente en la extremidad comprometida. La compresión crónica de la arteria puede llevar a daño irreversible con formación de trombos y aneurismas y a la consiguiente amputación de la extremidad, por lo que el diagnóstico y el tratamiento oportunos son de gran importancia para el paciente.The true prevalence of the popliteal artery entrapment syndrome is unknown, it is estimated to be 0.16%. It is considered as the main cause of intermittent claudication in young athletes without cardiovascular risk factors. It is characterized by the extrinsic compression of the popliteal artery either caused by defects of the muscle-tendon structures or by the hypertrophy of the gastrocnemius muscle leading to the arterial entrapment and symptoms of paresthesia, intermittent claudication and coldness of the affected limb. Chronic compression of the artery may lead to irreversible damage with formation of thrombi and aneurysms and the subsequent amputation of the limb. Therefore, correct diagnosis and treatment are of great importance for the patient.

    When a patient presents with spine problems, the spine surgeon would do well to avoid use of, reliance on, and acceptance of radiographs as the sole or primary source of information. Measurement of pelvic incidence and lumbar lordosis, although crucial, does not take into account the effort the patient must make to move, the level of involvement of other parts of the body, and the history of previous procedures and outcomes. Radiographs may show pathology that is not consistent with the appearance of the patient. How should we assess this situation? PMID:27015064

    2016-08-01

    Spinal paragangliomas (SP) are benign and overall rare extra-adrenal neuroendocrine tumors often diagnosed during workup for lower back pain. Complete surgical resection achieves both symptomatic relief and cure. We present a 32-year-old man with a longstanding history of lumbago and bilateral lower extremity pain found to have a lumbar paraganglioma at the level of the L3 vertebrae. The clinical, histopathological, and radiological characteristics are described, including the rare finding of superficial siderosis on MRI of the brain. A laminectomy with microscopic dissection of the intradural mass achieved complete debulking without evidence of residual tumor. Excellent prognosis can be achieved with complete surgical resection of SP without the need for adjuvant therapy. Therefore, care should be taken to distinguish these spinal tumors from those that appear similar but are more aggressive. As such, the radiological finding of superficial siderosis should raise the suspicion for SP when a vascular intradural extramedullary spinal tumor is observed. PMID:27032749

El articulo pretende exponer brevemente cómo están organizados los sistemas inmune y neuroendocrino, para después presentar los hallazgos que hasta el momento intentan dar explicación de las relaciones entre ambos con el sistema nervioso, así como las influencias de unos sobre otros, más concretamente expresar la relación entre los tres sistemas responsables de la defensa del organismo y, más ampliamente, de su mantenimiento homeostático. Cuando se trata de amenazas, el sistema nervioso central tiene que decidir qué sistema se pone en marcha, el sistema de estrés como energía para el ataque o la huida (un animal que nos quiere atacar, el sistema inmune para neutralizar el antígeno (un virus que nos quiere atacar o ambos (la energía es necesaria también para el sistema inmune.

    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

  16. Lateral Lumbar Interbody Fusion.

    Pawar, Abhijit; Hughes, Alexander; Girardi, Federico; Sama, Andrew; Lebl, Darren; Cammisa, Frank

    2015-12-01

    The lateral lumbar interbody fusion (LLIF) is a relatively new technique that allows the surgeon to access the intervertebral space from a direct lateral approach either anterior to or through the psoas muscle. This approach provides an alternative to anterior lumbar interbody fusion with instrumentation, posterior lumbar interbody fusion, and transforaminal lumbar interbody fusion for anterior column support. LLIF is minimally invasive, safe, better structural support from the apophyseal ring, potential for coronal plane deformity correction, and indirect decompression, which have has made this technique popular. LLIF is currently being utilized for a variety of pathologies including but not limited to adult de novo lumbar scoliosis, central and foraminal stenosis, spondylolisthesis, and adjacent segment degeneration. Although early clinical outcomes have been good, the potential for significant neurological and vascular vertebral endplate complications exists. Nevertheless, LLIF is a promising technique with the potential to more effectively treat complex adult de novo scoliosis and achieve predictable fusion while avoiding the complications of traditional anterior surgery and posterior interbody techniques.

    Swinging a golf club includes the rotation and extension of the lumbar spine. Golf-related low back pain has been associated with degeneration of the lumbar facet and intervertebral discs, and with spondylolysis. Reflective markers were placed directly onto the skin of 11young male amateur golfers without a previous history of back pain. Using a VICON system (Oxford Metrics, U.K.), full golf swings were monitored without a corset (WOC), with a soft corset (SC), and with a hard corset (HC), with each subject taking 3 swings. Changes in the angle between the pelvis and the thorax (maximum range of motion and angular velocity) in 3 dimensions (lumbar rotation, flexion-extension, and lateral tilt) were analyzed, as was rotation of the hip joint. Peak changes in lumbar extension and rotation occurred just after impact with the ball. The extension angle of the lumbar spine at finish was significantly lower under SC (38°) or HC (28°) than under WOC (44°) conditions (p golf swing can effectively decrease lumbar extension and rotation angles and angular velocity.Wearing lumbar corsets increased the rotational motion of the hip joint while reducing the rotation of the lumbar spine.

The maximum angular velocity after impact was significantly smaller under HC (94°/sec than under SC (177°/sec and WOC (191° /sec conditions, as were the lumbar rotation angles at top and finish. In contrast, right hip rotation angles at top showed a compensatory increase under HC conditions. Wearing a lumbar corset while swinging a golf club can effectively decrease lumbar extension and rotation angles from impact until the end of the swing. These effects were significantly enhanced while wearing an HC

    Spondylolysis is an osseous defect of the pars interarticularis, thought to be a developmental or acquired stress fracture secondary to chronic low-grade trauma. It is encountered most frequently in adolescents, most commonly involving the lower lumbar spine, with particularly high prevalence among athletes involved in certain sports or activities. Spondylolysis can be asymptomatic or can be a cause of spine instability, back pain, and radiculopathy. The biomechanics and pathophysiology of spondylolysis are complex and debated. Imaging is utilized to detect spondylolysis, distinguish acute and active lesions from chronic inactive non-union, help establish prognosis, guide treatment, and to assess bony healing. Radiography with satisfactory technical quality can often demonstrate a pars defect. Multislice CT with multiplanar reformats is the most accurate modality for detecting the bony defect and may also be used for assessment of osseous healing; however, as with radiographs, it is not sensitive for detection of the early edematous stress response without a fracture line and exposes the patient to ionizing radiation. Magnetic resonance (MR) imaging should be used as the primary investigation for adolescents with back pain and suspected stress reactions of the lumbar pars interarticularis. Several imaging pitfalls render MR imaging less sensitive than CT for directly visualizing the pars defects (regional degenerative changes and sclerosis). Nevertheless, the presence of bone marrow edema on fluid-sensitive images is an important early finding that may suggest stress response without a visible fracture line. Moreover, MR is the imaging modality of choice for identifying associated nerve root compression. Single-photon emission computed tomography (SPECT) use is limited by a high rate of false-positive and false-negative results and by considerable ionizing radiation exposure.

    Full Text Available A lumbar peritoneal (LP shunt is a technique of cerebrospinal fluid (CSF diversion from the lumbar thecal sac to the peritoneal cavity. It is indicated under a large number of conditions such as communicating hydrocephalus, idiopathic intracranial hypertension, normal pressure hydrocephalus, spinal and cranial CSF leaks, pseudomeningoceles, slit ventricle syndrome, growing skull fractures which are difficult to treat by conventional methods (when dural defect extends deep in the cranial base or across venous sinuses and in recurrent cases after conventional surgery, raised intracranial pressure following chronic meningitis, persistent bulging of craniotomy site after operations for intracranial tumors or head trauma, syringomyelia and failed endoscopic third ventriculostomy with a patent stoma. In spite of the large number of indications of this shunt and being reasonably good, safe, and effective, very few reports about the LP shunt exist in the literature. This procedure did not get its due importance due to some initial negative reports. This review article is based on search on Google and PubMed. This article is aimed to review indications, complications, results, and comparison of the LP shunt with the commonly practiced ventriculoperitoneal (VP shunt. Shunt blocks, infections, CSF leaks, overdrainage and acquired Chiari malformation (ACM are some of the complications of the LP shunt. Early diagnosis of overdrainage complications and ACM as well as timely appropriate treatment especially by programmable shunts could decrease morbidity. Majority of recent reports suggest that a LP shunt is a better alternative to the VP shunt in communicating hydrocephalus. It has an advantage over the VP shunt of being completely extracranial and can be used under conditions other than hydrocephalus when the ventricles are normal sized or chinked. More publications are required to establish its usefulness in the treatment of wide variety of indications.

    Full Text Available Impaired motor and sensory functions have been associated with low back pain (LBP. This includes disturbances in a wide range of sensorimotor control e.g. sensory dysfunctions, impaired postural responses and psychomotor control. However, the physiological mechanisms, clinical relevance and characteristics of these findings in different spinal pathologies require further clarification. The purposes of this study were to investigate postural control, lumbar muscle function, movement perception and associations between these findings in healthy volunteers (n=35, patients with lumbar disc herniation (n=20 and lumbar spinal stenosis (LSS, n=26. Paraspinal muscle responses for sudden upper limb loading and muscle activation during flexion-extension movement and the lumbar endurance test were measured by surface electromyography (EMG. Postural stability was measured on a force platform during two- and one-footed standing. Lumbar movement perception was assessed in a motorised trunk rotation unit in the seated position. In addition, measurements of motor-(MEP and somatosensory evoked potentials (SEP and needle EMG examination of lumbar multifidus muscles were performed in the LSS patients. Clinical and questionnaire data were also recorded. A short latency paraspinal muscle response (~50 ms for sudden upper limb loading was observed. The latency of the response was shortened by expectation (p=0.017. The response latency for unexpected loading was similar in healthy persons and disc herniation patients but the latency was not shortened by expectation in the patients (p = 0.014. Also impaired postural control (p < 0.05 and lumbar movement perception (p = 0.012 were observed in disc herniation patients. The impaired lumbar movement perception (p=0.054 and anticipatory muscle activation (p = 0.043 tended to be restored after successful surgery but postural control had still not recovered after 3 months of follow-up.

    BACKGROUND: Lumbar hernia is a rare congenital or acquired defect of the posterior abdominal wall. The acquired type is more common and occurs mainly as an incisional defect after lfank surgery. Incarceration or strangulation of hernia contents is uncommon. METHOD: Segmental liver incarceration through a recurrent incisional lumbar defect was diagnosed in a 58 years old woman by magnetic resonance imaging. RESULTS: The patient underwent an open repair of the com-plicated hernia. An expanded polytetralfouoroethylene (e-PTFE) mesh was fashioned as a sublay prosthesis. She had an uncomplicated postoperative course. Follow-up examinations revealed no evidence of recurrence. CONCLUSIONS: Although lumbar hernia rarely results in incarceration or strangulation, early repair is necessary because of the risks of complications and the increasing dififculty in repairment as it enlarges. Surgical repair is often dififcult and challenging.

    Full Text Available La memoria y la emoción son temas de extenso e intenso estudio dentro de la comunidad científica mundial pues impactan directamente en la construcción del historial de las comunidades sobre el que se fundamenta la preservación de la especie, los repertorios de interacción entre individuos de una comunidad y en el caso de los humanos sirven de fundamento para la construcción de la sociedad y sus diferentes áreas de progreso. Desde hace algún tiempo surgieron dos teorías contrapuestas sobre el origen de las emociones y debido al auge histórico del momento tuvo mayor preponderancia la que daba preferencia al cerebro como el órgano que generaba las distintas experiencias que podían establecer una emoción; no obstante, experiencias recientes han demostrado que el componente periférico del sistema nervioso autónomo tiene una fuerte influencia sobre las emociones y que las intervenciones sobre dicho sistema pueden interferir de forma deletérea o no en la creación de memoria de dichos eventos, es decir en la memoria emocional.

    Full Text Available A 70-year-old outpatient presented with a chief complaint of sudden left leg motor weakness and sensory disturbance. He had undergone L4/5 posterior interbody fusion with L3–5 posterior fusions for spondylolisthesis 3 years prior, and the screws were removed 1 year later. He has been followed up for 3 years, and there had been no adjacent segment problems before this presentation. Lumbar magnetic resonance imaging (MRI showed a large L2/3 disc hernia descending to the L3/4 level. Compared to the initial MRI, this hernia occurred in an “intact” disc among multilevel severely degenerated discs. Right leg paresis and bladder dysfunction appeared a few days after admission. Microscopic lumbar disc herniotomy was performed. The right leg motor weakness improved just after the operation, but the moderate left leg motor weakness and difficulty in urination persisted.

  7. Lumbar epidural varices: An unusual cause of lumbar claudication

    2016-01-01

    Full Text Available Lumbar epidural varices can also present with radiculopathy similar to acute intervertebral disc prolapse (IVDP. However as the magnetic resonance imaging (MRI in these patients are usually normal without significant compressive lesions of the nerve roots, the diagnosis is commonly missed or delayed leading to persistent symptoms. We present a rare case of acute severe unilateral claudication with a normal MRI unresponsive to conservative management who was treated surgically. The nerve root on the symptomatic side was found to be compressed by large anterior epidural varices secondary to an abnormal cranial attachment of ligamentum flavum. Decompression of the root and coagulation of the varices resulted in complete pain relief. To conclude, lumbar epidural varices should be considered in the differential diagnosis of acute onset radiculopathy and claudication in the absence of significant MRI findings.

Resultados. Las lesiones de 40 pacientes fueron producidas por accidente en moto. En 22 solo se transfirió el NSE con el NEA; con esto, se recuperó abducción de hombro de 33º. A 8 pacientes se les combinó con reparación del axilar; mejorando la abducción a 81º. En 30 pacientes con neurotización del nervio cubital o mediano para el bíceps, se obtuvo respuesta a los 3 o 4 meses. Al final, la flexión del codo era de 116º y M4. Conclusión. Los mejores resultados en hombro fueron con la combinación de NSE y del nervio axilar; con esta, se logró 81º de abducción. La rotación externa mejoró en 28,5% de los pacientes, con respuesta tardía. Mientras que la neurotización del bíceps con fascículos del cubital consiguió una flexión de 116º, muy comparable con otras series. Hoy esta técnica es el gold estandard para la reconstrucción de flexión del codo.

Overview of Literature IT professionals have to work for long hours in a sitting position, which can affect lumbar lordosis and lumbar core strength. Methods Flexicurve was used to assess the lumbar lordosis, and pressure biofeedback was used to assess the lumbar core strength in the IT professionals. All subjects, both male and female, with and without complaint of low back pain and working for two or more years were included, and subjects with a history of spinal surgery or spinal deformity were excluded from the study. Analysis was done using Pearson's correlation. Results For the IT workers, no correlation was seen between lumbar lordosis and lumbar core strength (r=–0.04); however, a weak negative correlation was seen in IT people who complained of pain (r=–0.12), while there was no correlation of lumbar lordosis and lumbar core in IT people who had no complains of pain (r=0.007). Conclusions The study shows that there is no correlation of lumbar lordosis and lumbar core strength in IT professionals, but a weak negative correlation was seen in IT people who complained of pain.

    Full Text Available Abstract Background Exposure of the anterior or lateral lumbar via the retroperitoneal approach easily causes injuries to the lumbar plexus. Lumbar plexus injuries which occur during anterior or transpsoas lumbar spine exposure and placement of instruments have been reported. This study aims is to provide more anatomical data and surgical landmarks in operations concerning the lumbar plexus in order to prevent lumbar plexus injuries and to increase the possibility of safety in anterior approach lumbar surgery. Methods To study the applied anatomy related to the lumbar plexus of fifteen formaldehyde-preserved cadavers, Five sets of Virtual Human (VH data set were prepared and used in the study. Three-dimensional (3D computerized reconstructions of the lumbar plexus and their adjacent structures were conducted from the VH female data set. Results The order of lumbar nerves is regular. From the anterior view, lumbar plexus nerves are arranged from medial at L5 to lateral at L2. From the lateral view, lumbar nerves are arranged from ventral at L2 to dorsal at L5. The angle of each nerve root exiting outward to the corresponding intervertebral foramen increases from L1 to L5. The lumbar plexus nerves are observed to be in close contact with transverse processes (TP. All parts of the lumbar plexus were located by sectional anatomy in the dorsal third of the psoas muscle. Thus, access to the psoas major muscle at the ventral 2/3 region can safely prevent nerve injuries. 3D reconstruction of the lumbar plexus based on VCH data can clearly show the relationships between the lumbar plexus and the blood vessels, vertebral body, kidney, and psoas muscle. Conclusion The psoas muscle can be considered as a surgical landmark since incision at the ventral 2/3 of the region can prevent lumbar plexus injuries for procedures requiring exposure of the lateral anterior of the lumbar. The transverse process can be considered as a landmark and reference in surgical

  1. Lumbar discoidectomy by minimal incision

    International Nuclear Information System (INIS)

    The objective is to review the experience with the presented technique. Background: Lumbar disc herniation is the most frequent cause of low back pain, becoming a disabling condition. There are multiple surgical procedures to treat lumbar disc herniation; however, review of the literature found similar outcomes within open and percutaneous techniques. Materials and methods: Seventy patients with lumbar disc herniation were operated within 1990 and 2003, 38 years-old of mean age, 6 years 3 months of mean follow-up. Results were evaluated by Spain type, severity of herniation, and presence of neurological deficit, preoperative treatment, and complications and assessment of outcomes according to Ebeling's Scale. Results: 91% of disc herniation were by a physical mechanism. 57% were protruded disc herniation; most common paint type was lumbo-radicular (83%). Disturbances Motor improved in 100% and 69% of sensitive. There were no infections. According to Ebeling's Scale, 94,3% of patients had excellent outcomes, 4.3% well and 1.4% had regular outcomes. Recommendations: The minimally invasive technique is safe and has low incidence of complications, this promotes early clinical recovery and reintegration to daily and laboral activities. Costs are less with this technique than the microsurgical technique because of this does not require of high-technology equipment

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As técnicas de bloqueios nervosos guiados por ultra-som são baseadas na visualização direta das estruturas nervosas, da agulha de bloqueio e das estruturas anatômicas adjacentes. Desta maneira, é possível depositar a solução de anestésico local precisamente em torno dos nervos e acompanhar a sua dispersão em tempo real, obtendo-se, assim, um bloqueio mais eficaz, de menor latência, menor dependência de referências anatômicas, menor volume de solução anestésica e maior segurança. CONTEÚDO: O artigo revisa os aspectos relativos aos mecanismos físicos para formação de imagens, a anatomia ultra-sonográfica do neuroeixo e dos plexos braquial e lombossacral, os equipamentos e materiais empregados nos bloqueios, os ajustes do aparelho de ultra-som para melhorar as imagens, os planos de visualização das agulhas de bloqueio e as técnicas e o treinamento em bloqueios guiados por ultra-som. CONCLUSÕES: Os passos para se obter sucesso em anestesia regional incluem a identificação exata da posição dos nervos, a localização precisa da agulha, sem lesões nas estruturas adjacentes e, finalmente, a injeção cuidadosa de anestésico local junto aos nervos. Embora a neuroestimulação forneça grande auxílio na identificação dos nervos, esta não consegue, isoladamente, preencher todas essas exigências. Por isso, acredita-se que os bloqueios guiados por ultra-som serão a técnica de eleição para anestesia regional num futuro não muito distante.JUSTIFICATIVA Y OBJETIVOS: Las técnicas de bloqueos nerviosos guiados por ultrasonido se basan en la visualización directa de las estructuras nerviosas, de la aguja de bloqueo y de las estructuras anatómicas adyacentes.

    Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

    Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method. PMID:27446525

    Full Text Available La depresión clínica es una enfermedad física y psíquica que presenta bases neuropatológicas, sin embargo aún no se tiene un conocimiento exacto del origen o causas de esta enfermedad. Se conoce que existe un componente genético, aunque el componente ambiental en el desarrollo de la depresión es innegable. El estrés juega un rol esencial en el desencadenamiento de la depresión. La interacción y respuesta del sistema endocrino, inmune y nervioso se encuentran afectadas en este desorden. La observación de los efectos de los antidepresivos sobre la neurotransmisión monoaminérgica ha llevado hace muchos años a la hipótesis de las monoaminas de la depresión. Sin embargo, esta hipótesis ya no puede explicar muchos de los efectos de las drogas antidepresivas. La nueva hipótesis para explicar los efectos de los antidepresivos es la de neuroplasticidad neuronal. Esta hipótesis propone que los cambios que esas drogas producen sobre diversos sistemas, entre ellos el sistema nervioso, el inmune y el endocrino, son capaces de inducir cambios neuroadaptativos en el cerebro. La neuroplasticidad ha sido definida como la habilidad del cerebro para reorganizarse a sí mismo y formar nuevas conexiones neuronales a lo largo de la vida. Se propone que el mecanismo por el cual los antidepresivos logran sus efectos es mediante la neuroplasticidad.Clinical depression is a physical and psychic disease that has neuropathological basis, although the clear understanding of its ethiopathology is still missing.

    Eosinophilic granuloma (EG) is a rare disease but is more common in adults than children. It's often self-limiting. Spinal involvement is rare. It is the localized and most benign form of Langerhans' cell histiocytosis (previously known as histiocytosis X), characterised by lytic lesions in one or more bones. Spontaneous resolution of vertebral body lesions is very rare. In this case, the patient had one EG in a cervical vertebra and a similar lesion in a lumbar vertebra. This case is important because it featured a symptomatic lesion in the cervical spine accompanied by an asymptomatic lesion in a lumbar vertebra. We treated the cervical lesion by surgical fusion and followed the lumbar lesion up conservatively, with the patient in a corset. After 8 years of follow-up, control MRI showed that the lumbar lesion had spontaneously resolved. PMID:14963750

    Full Text Available To date no studies have been published on preoperative education forpatients who had lumbar surgery. The aim of this study was to determine if there is a demand for preoperative education for patients who had lumbar surgery for radiculopathy. A convenience sample of 47 patients who had lumbar surgery and a random sample of 141 physiotherapists involved in treating patients who had lumbar surgery completed a newly developed spinal surgery questionnaire. The data were analyzed using descriptiveand inferential statistical tests. Results showed that 100% of the patients and 99% of therapists view preoperative education to be an important component for lumbar surgery for radiculopathy. The most important factors identifiedfor inclusion in preoperative educational programs were reason for surgery, risks associated with surgery, limitations following surgery and more education regarding pain. The preferred method of education delivery was verbal one-on-one education. This study demonstrates that there is a demand for preoperative education for patients who had lumbar surgery.

    Lumbar spondylolisthesis is one of the most common spinal diseases. It is caused by the anterior shift of a lumbar vertebrae relative to subjacent vertebrae. In current clinical practices, staging of spondylolisthesis is often conducted in a qualitative way. Although meyerding grading opens the door to stage spondylolisthesis in a more quantitative way, it relies on the manual measurement, which is time consuming and irreproducible. Thus, an automatic measurement algorithm becomes desirable for spondylolisthesis diagnosis and staging. However, there are two challenges. 1) Accurate detection of the most anterior and posterior points on the superior and inferior surfaces of each lumbar vertebrae. Due to the small size of the vertebrae, slight errors of detection may lead to significant measurement errors, hence, wrong disease stages. 2) Automatic localize and label each lumbar vertebrae is required to provide the semantic meaning of the measurement. It is difficult since different lumbar vertebraes have high similarity of both shape and image appearance. To resolve these challenges, a new auto measurement framework is proposed with two major contributions: First, a learning based spine labeling method that integrates both the image appearance and spine geometry information is designed to detect lumbar vertebrae. Second, a hierarchical method using both the population information from atlases and domain-specific information in the target image is proposed for most anterior and posterior points positioning. Validated on 258 CT spondylolisthesis patients, our method shows very similar results to manual measurements by radiologists and significantly increases the measurement efficiency. PMID:26849859

    Full Text Available Lumbosacral nerve root anomalies are the leading cause of lumbar surgery failures. Although co-occurrence of lumbar spondylolysis and disc herniation is common, it is very rare to observe that a nerve root anomaly accompanies these lesions. A 49-year-old male patient presented with sudden-onset right leg pain. Examinations revealed L5/S1 lumbar spondylolysis and disc herniation. At preoperative period, he was also diagnosed with lumbosacral root anomaly. Following discectomy and root decompression, stabilization was performed. The complaints of the patient diagnosed with lumbosacral root anomaly at intraoperative period were improved at postoperative period. It should be remembered that in patients with lumbar disc herniation and spondylolysis, lumbar root anomalies may coexist when clinical and neurological picture is severe. Preoperative and perioperative assessments should be made meticulously to prevent neurological injury.

    International Nuclear Information System (INIS)

    Seventeen patients with sciatica and isthmic lumbar spondylolisthesis were studied with magnetic resonance (MR) imaging. In 13, myelography was also performed: 5 had dural sac deformation and root sleeve shortening, 2 had deformation with unilateral root sleeve shortening, one had bilateral root sleeve shortening only, and one had sac deformation only. In 4, myelography was normal. On sagittal MR examinations the neural foramen had an altered shape bilaterally with the long axis horizontal in all cases. In addition to altered shape the following was found in the 33 foramina evaluated. I: Normal nerve (n=8), II: Compressed nerve (n=16); III: Disappearance of fat, nerve not possible to identify (n=9). In patients with unilateral sciatica, the degree of foraminal stenosis correlated well with the side of symptoms. Coronal views showed the course of the nerve and pedicular kinking. Eight patients underwent decompressive surgery which revealed nerve compression by hypertrophic fibrous tissue and pedicular kinking, which correlated well with the findings on MR. Since the site of nerve compression often was peripheral to the root sleeves, myelography did not give complete information. (orig.)

    The aim of this study was to demonstrate the feasibility of MR-guided lumbar sympathicolysis (LSL) in a non-selected patient population. One hundred one MR-guided LSL procedures were performed in 89 patients according to Haaga's technique using a horizontally open clinical MR system (0.2 T) and non-ferromagnetic 20-G cannulas (neurolysis, n=93; blockade, n=8). Only gradient-recalled sequences in either single or multislice mode [fast imaging with steady-state precession (FISP) and fast low-angle shot] were applied for anatomical survey and needle guiding. Bupivacaine injection was monitored with MR fluoroscopically. Fluid distribution was subsequently documented in a CT scan in 65 patients. Ninety-one LSL procedures could be successfully completed. Ten patients were not treated using MR due to patient inconvenience, severe motion artifacts (n=4 each), excessive spondylophytes, and retroperitoneal hematoma (n=1 each). One case of ureteral necrosis occurred. Motion artifacts were rated less severe in single-slice FISP sequences and in obese patients. An average of 3.48 sequence measurements were required for definitive needle placement. Average table time was 32.3 min. An MR-guided LSL is feasible and can be performed with acceptable safety and time effort. It can be recommended for repeated sympathetic blockades in younger patients to avoid cumulative irradiation associated with CT guidance. (orig.)

One hundred one MR-guided LSL procedures were performed in 89 patients according to Haaga's technique using a horizontally open clinical MR system (0.2 T) and non-ferromagnetic 20-G cannulas (neurolysis, n=93; blockade, n=8). Only gradient-recalled sequences in either single or multislice mode [fast imaging with steady-state precession (FISP) and fast low-angle shot] were applied for anatomical survey and needle guiding. Bupivacaine injection was monitored with MR fluoroscopically. Fluid distribution was subsequently documented in a CT scan in 65 patients. Ninety-one LSL procedures could be successfully completed. Ten patients were not treated using MR due to patient inconvenience, severe motion artifacts (n=4 each), excessive spondylophytes, and retroperitoneal hematoma (n=1 each). One case of ureteral necrosis occurred. Motion artifacts were rated less severe in single-slice FISP sequences and in obese patients. An average of 3.48 sequence measurements were required for definitive needle placement. Average table time was 32.3 min. An MR-guided LSL is feasible and can be performed with acceptable safety and time effort. It can be recommended for repeated sympathetic blockades in younger patients to avoid cumulative irradiation associated with CT guidance. (orig.)

    Background To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lordosis on the OSI frame after an intraoperative prone position. We evaluated the effect of spondyloli...

    A new musculoskeletal model for the lumbar spine is described in this paper. This model features a rigid pelvis and sacrum, the five lumbar vertebrae, and a rigid torso consisting of a lumped thoracic spine and ribcage. The motion of the individual lumbar vertebrae was defined as a fraction of the net lumbar movement about the three rotational degrees of freedom: flexion-extension lateral bending, and axial rotation. Additionally, the eight main muscle groups of the lumbar spine were incorporated using 238 muscle fascicles with prescriptions for the parameters in the Hill-type muscle models obtained with the help of an extensive literature survey. The features of the model include the abilities to predict joint reactions, muscle forces, and muscle activation patterns. To illustrate the capabilities of the model and validate its physiological similarity, the model's predictions for the moment arms of the muscles are shown for a range of flexion-extension motions of the lower back. The model uses the OpenSim platform and is freely available on https://www.simtk.org/home/lumbarspine to other spinal researchers interested in analyzing the kinematics of the spine. The model can also be integrated with existing OpenSim models to build more comprehensive models of the human body. PMID:21318374

    Degenerative disease of the lumbar spine is a common and increasingly prevalent condition that is often implicated as the primary reason for chronic low back pain and the leading cause of disability in the western world. Surgical management of lumbar degenerative disease has historically been approached by way of open surgical procedures aimed at decompressing and/or stabilizing the lumbar spine. Advances in technology and surgical instrumentation have led to minimally invasive surgical techniques being developed and increasingly used in the treatment of lumbar degenerative disease. Compared to the traditional open spine surgery, minimally invasive techniques require smaller incisions and decrease approach-related morbidity by avoiding muscle crush injury by self-retaining retractors, preventing the disruption of tendon attachment sites of important muscles at the spinous processes, using known anatomic neurovascular and muscle planes, and minimizing collateral soft-tissue injury by limiting the width of the surgical corridor. The theoretical benefits of minimally invasive surgery over traditional open surgery include reduced blood loss, decreased postoperative pain and narcotics use, shorter hospital length of stay, faster recover and quicker return to work and normal activity. This paper describes the different minimally invasive techniques that are currently available for the treatment of degenerative disease of the lumbar spine. PMID:25610845

    The aims of this preliminary study were to demonstrate the feasibility of in vivo diffusion tensor imaging (DTI) and fibre tracking (FT) of the lumbar nerve roots, and to assess potential differences in the DTI parameters of the lumbar nerves between healthy volunteers and patients suffering from disc herniation. Nineteen patients with unilateral sciatica related to posterolateral or foraminal disc herniation and 19 healthy volunteers were enrolled in this study. DTI with tractography of the L5 or S1 nerves was performed. Mean fractional anisotropy (FA) and mean diffusivity (MD) values were calculated from tractography images. FA and MD values could be obtained from DTI-FT images in all controls and patients. The mean FA value of the compressed lumbar nerve roots was significantly lower than the FA of the contralateral nerve roots (p=0.0001) and of the nerve roots of volunteers (p=0.0001). MD was significantly higher in compressed nerve roots than in the contralateral nerve root (p=0.0002) and in the nerve roots of volunteers (p=0.04). DTI with tractography of the lumbar nerves is possible. Significant changes in diffusion parameters were found in the compressed lumbar nerves. (orig.)

    This study aims to assess the results of extended transforaminal lumbar interbody fusion (TLIF) for a two surgeon, single institution series. In total, extended TLIF with bilateral decompression was performed in 57 patients. Pain, American Spinal Injury Association scores, patient demographics, body mass index (BMI), perioperative indices and radiographic measurements were recorded and analysed. The surgeries were performed between February 2011 and January 2014 on 38 women and 19 men. The mean patient age was 62.86 years, and the mean BMI was 30.31 kg/m(2). In 49 patients, spondylolisthesis was the primary indication. The mean intraoperative time was 284.65 min, and this decreased as the series progressed. The median length of stay was 5 days (range: 2-9). The surgical complication rate was 19.3%. Two patients died from cardiopulmonary complications. Single level TLIF was performed in 78.9% of the cohort, with L4/5 the most commonly fused level. Significant pain reduction was achieved from a mean (± standard deviation) preoperative visual analogue scale (VAS) of 8.28 ± 1.39 to 1.50 ± 1.05 at 12 months postoperatively. No patients deteriorated neurologically. Spondylolisthesis was significantly corrected from a preoperative mean of 6.82 mm to 2.80 mm postoperatively. Although there is a learning curve associated with the procedure, extended TLIF with bilateral facet joint removal and decompression appeared to be a safe and effective alternative to other fusion techniques, and our results were comparable to other published case series. The stabilisation and correction of spinal deformity reduces pain, aids neurologic recovery and improves quality of life. PMID:26358199

    Epidural steroid injections (ESI) are a common treatment for back pain management. ESI-related complications have increased with the growing number of procedures. We report a case of cervical meningomyelitis followed by multiple lumbar ESI. A 60-year-old male with diabetes mellitus presented to our hospital with severe neck pain. He had a history of multiple lumbar injections from a local pain clinic. After admission, high fever and elevated inflammatory values were detected. L-spine magnetic resonance imaging (MRI) revealed hematoma in the S1 epidural space. Antibiotic treatment began under the diagnosis of a lumbar epidural abscess. Despite the treatment, he started to complain of weakness in both lower extremities. Three days later, the weakness progressed to both upper extremities. C-spine MRI revealed cervical leptomeningeal enhancement in the medulla oblongata and cervical spinal cord. Removal of the epidural abscess was performed, but there was no neurological improvement.

    In deformity surgery, anterior lumbar interbody fusion provides excellent biomechanical support, creates a broad surface area for arthrodesis, and induces lordosis in the lower lumbar spine. Preoperative MRI, plain radiographs, and, when available, CT scan should be carefully assessed for sacral slope as it relates to pubic symphysis, position of the great vessels (especially at L4/5), disc space height, or contraindication to an anterior approach. This video demonstrates the steps in an anterior surgical procedure with minimal open exposure. The video can be found here: https://youtu.be/r3bC4_vu1hQ . PMID:27364424

    Lumbar disk herniations occur frequently and are often associated with leg pain, weakness, and paresthesias. Fortunately, the natural outcomes of radiculopathy due to a disk herniation are generally favorable, and the vast majority of patients improve with nonoperative care. Surgical intervention is reserved for patients who have significant pain that is refractory to at least 6 weeks of conservative care, patients who have a severe or progressive motor deficit, or patients who have any symptoms of bowel or bladder dysfunction. This paper reviews the preoperative and postoperative considerations, as well as the surgical technique, for a microdiscectomy for a lumbar intervertebral disk herniation. PMID:26710186

    Surgical management of lumbar spine conditions can produce excellent outcomes in athletes. Microdiscectomy for lumbar disc herniation has favorable outcomes; most athletes return to play at preoperative performance levels. Direct pars repair is successful in younger athletes, with high rates of return to play for a variety of fixation techniques. Fusion in athletes with scoliosis is a negative predictor. There are few evidence-based return to play criteria. Athletes should demonstrate full resolution of symptoms and flexibility, endurance, and strength before returning to play. Deciding when to return an athlete to sport depends on particular injury sustained, sport, and individual factors. PMID:27543402

    As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy. PMID:27534095

    Introducción: la Aspergilosis Invasiva (AI) del Sistema Nervioso Central (SNC) es infrecuente y ocurre generalmente en pacientes inmunocomprometidos. Puede presentarse con cuadros de meningitis, aneurismas micóticos, infartos o abscesos. Es una infección con pronóstico reservado y puede afectar el SNC de forma primaria o secundaria a partir de un foco que se disemina por vía hematógena. Presentamos el caso de un paciente con AI con invasión primaria a nivel óseo y diseminación posterior al cerebro. Caso clínico: Paciente masculino de 25 años con diagnóstico de leucemia linfática aguda en tratamiento quimioterápico que presentó neumonitis por metotrexate por lo que inicia tratamiento con corticoides. Posteriormente agregó cervicalgia y con el diagnóstico de osteomielitis cervical se realiza punción bajo tomografía computada (TC) sin aislarse gérmenes. Se colocó Halo Vest e inició tratamiento antibiótico empírico. Posteriormente presentó afasia de expresión secundaria a lesión frontal izquierda. Se realizó evacuación de absceso cerebral aislando A. fumigatus. El tratamiento antibiótico específico posterior permitió una buena respuesta clínica y radiológica. Conclusión: La presencia de lesiones en el SNC de pacientes inmunocomprometidos debe incluir a las micosis como diagnóstico diferencial. La evacuación quirúrgica permite llegar rápidamente al diagnóstico mejorando la respuesta posterior al tratamiento antibiótico. Para evaluar la respuesta terapéutica y posibles recaídas se debe realizar un seguimiento periódico clínico radiológico.

    Full Text Available Background. Several different techniques exist to address the pain and disability caused by isolated nerve root impingement. Failure to adequately decompress the lumbar foramen may lead to failed back surgery syndrome. However, aggressive treatment often causes spinal instability or may require fusion for satisfactory results. We describe a novel technique for decompression of the lumbar nerve root and demonstrate its effectiveness in relief of radicular symptoms. Methods. Partial facetectomy was performed by removal of the medial portion of the superior facet in patients with lumbar foraminal stenosis. 47 patients underwent the procedure from 2001 to 2010. Those who demonstrated neurogenic claudication without spinal instability or central canal stenosis and failed conservative management were eligible for the procedure. Functional level was recorded for each patient. These patients were followed for an average of 3.9 years to evaluate outcomes. Results. 27 of 47 patients (57% reported no back pain and no functional limitations. Eight of 47 patients (17% reported moderate pain, but had no limitations. Six of 47 patients (13% continued to experience degenerative symptoms. Five of 47 patients (11% required additional surgery. Conclusions. Partial facetectomy is an effective means to decompress the lumbar nerve root foramen without causing spinal instability.

  5. Acute Sciatic Neuritis following Lumbar Laminectomy

    Directory of Open Access Journals (Sweden)

    Foad Elahi

    2014-01-01

    Full Text Available It is commonly accepted that the common cause of acute/chronic pain in the distribution of the lumbosacral nerve roots is the herniation of a lumbar intervertebral disc, unless proven otherwise. The surgical treatment of lumbar disc herniation is successful in radicular pain and prevents or limits neurological damage in the majority of patients. Recurrence of sciatica after a successful disc surgery can be due to many possible etiologies. In the clinical setting we believe that the term sciatica might be associated with inflammation. We report a case of acute sciatic neuritis presented with significant persistent pain shortly after a successful disc surgery. The patient is a 59-year-old female with complaint of newly onset sciatica after complete pain resolution following a successful lumbar laminectomy for acute disc extrusion. In order to manage the patient’s newly onset pain, the patient had multiple pain management visits which provided minimum relief. Persistent sciatica and consistent physical examination findings urged us to perform a pelvic MRI to visualize suspected pathology, which revealed right side sciatic neuritis. She responded to the electrical neuromodulation. Review of the literature on sciatic neuritis shows this is the first case report of sciatic neuritis subsequent to lumbar laminectomy.

    An iliac arteriovenous fistula may rarely complicate lumbar laminectomy, particularly at the L4-L5 level. We present such a complication in a 45-year-old man who presented in our institution with a postlaminectomy iliac arteriovenous fistula and severe congestive heart failure. Repair of the fistulous orifice and tubular reconstruction of the iliac artery were successfully performed.

  10. Physiological pattern of lumbar disc height

    International Nuclear Information System (INIS)

    Purpose of this study is to present a new method of quantifying objectively the height of all discs in lateral radiographs of the lumbar spine and of analysing the normal craniocaudal sequence pattern of lumbar disc heights. Methods: The new parameter is the ventrally measured disc height corrected for the dependence on the angle of lordosis by normalisation to mean angles observed in the erect posture of healthy persons. To eliminate radiographic magnification, the corrected ventral height is related to the mean depth of the cranially adjoining vertebra. In this manner lumbar disc heights were objectively measured in young, mature and healthy persons (146 males and 65 females). The craniocaudal sequence pattern was analysed by mean values from all persons and by height differences of adjoining discs in each individual lumbar spine. Results: Mean normative values demonstrated an increase in disc height between L1/L2 and L4/L5 and a constant or decreasing disc height between L4/L5 and L5/S1. However, this 'physiological sequence of disc height in the statistical mean' was observed in only 36% of normal males and 55% of normal females. Conclusion: The radiological pattern of the 'physiological sequence of lumbar disc height' leads to a relevant portion of false positive pathological results especially at L4/L5. An increase of disc height from L4/L5 to L5/S1 may be normal. The recognition of decreased disc height should be based on an abrupt change in the heights of adjoining discs and not on a deviation from a craniocaudal sequence pattern. (orig.)

  12. General practitioners' willingness to request plain lumbar spine radiographic examinations

    International Nuclear Information System (INIS)

    Objectives: To examine general practitioners' attitudes to plain lumbar spine radiographic examinations. Design: A postal questionnaire consisting of questions on background data and doctors' opinions about plain lumbar spine radiographic examinations, as well as eight vignettes (imaginary patient cases) presenting indications for lumbar radiography, and five vignettes focusing on the doctors' willingness to request lumbar radiography on the basis of patients' age and duration of symptoms. The data were analysed according to the doctor's age, sex, workplace and the medical school of graduation. Setting: Finland. Subjects: Six hundred and fifteen randomly selected physicians working in primary health care (64% of original target group). Results: The vignettes revealed that the use of plain lumbar radiographic examination varied between 26 and 88%. Patient's age and radiation protection were the most prominent factors influencing doctors' decisions to request lumbar radiographies. Only slight differences were observed between the attitudes of male and female doctors, as well as between young and older doctors. Doctors' willingness to request lumbar radiographies increased with the patient's age in most vignettes. The duration of patients' symptoms had a dramatic effect on the doctor's decision: in all vignettes, doctors were more likely to request lumbar radiography when patient's symptoms had exceeded 4 weeks. Conclusions: General practitioners commonly use plain lumbar spine radiographic examinations, despite its limited value in the diagnosis of low back pain. Further consensus and medical education is needed to clarify the indications for plain lumbar radiographic examination

  13. Surgical outcome of posterior lumbar interbody fusion with pedicle screw fixation for lumbar spondylolisthesis

    International Nuclear Information System (INIS)

    Problems of lumbar spondylolisthesis treatment are many surgical tactics, elderly patient, osteoporosis, complications and recurrence of the symptoms. PLIF (posterior lumbar interbody fusion) and PS (pedicle screw) fixation technique for lumbar spondylolisthesis provide good patient satisfaction. Good outcome has been reported by only laminectomy alone, but patient satisfaction becomes worse year after year. The role of instrumentation for lumbar spondylolisthesis is decompression of the nerve root, correction of lumbar pathologies, bony fusion and early mobilization. We show our surgical technique and long term outcome of PLIF with PS for lumbar spondylolisthesis. Three hundred and fifty cases of lumbar spondylolisthesis were operated on in Department of Neurosurgery, Fujita Health University during the period of from December 1992 to August 2008. Patient background: age 16-84 years old (mean 62.5), Gender: male 153, female 197. Follow-up period 1-180 months (mean 61.2). Degenerative: 255, Isthmic: 63, Dysplastic: 10, Fracture: 5 and scoliosis 16 cases. Surgical procedure was PS with interbody fusion cage: 331, Hybrid cage (titanium cage with hydroxyapatite) 314, PS with Cerabone: 2 and PS with autograft: 17. CT was done to evaluate bony fusion postoperatively. Post operative improvements by JOA (Japan Orthopedic Association) score is 11.4 before surgery, 24.1 (post op. within 2 years), 25.4 (post op. 2-5 years), 25.0 (post op. 5-10 years) and 22.4 (post op. 10-15 years). Significant improvements were observed in %Slip and Slip angle but no remarkable change was observed in lumbar lordotic angle by postoperative X-ray evaluation. No root injury, and systemic complication except 4 cases of cerebrospinal fluid (CSF) leakage during surgery. Two cases were reoperated in whom cage with autograft migration due to pseudoarthrosis. Two cases had to undergo screw and cage system removal due to infection. Two cases of adjacent level stenosis had to undergo operation 10

    Fifteen men with lethal central nervous system trauma were studied to look for the presence of cardiac lesions. They were between 16 and 60 years of age with an average of 32. There were five gunshot wounds and nine central nervous system contusions; four of these occurred in traffic accidents. The remaining patient was wounded with a machete. AII patients were adequately treated since the beginning of their hospital stay and 14 were surgically managed. Average survival after trauma was 6.6 days. In every case there were ECG alterations, the most frequent being sinusal tachycardia. Creatine phosphokinase levels were high in all and the MB fraction was above normal levels in three patients in whom heart damage was confirmed at autopsy. In 40% of cases heart lesions were found and the most common was subendocardial hemorrhage. In an era of increasing need of organs for transplantation potential donors have to be thoroughly studied to determine if heart lesions have occurred and to decide if they are suitable as transplant organs.

    A 9 yr old castrated male golden retriever weighing 36 kg was presented for evaluation of progressive left pelvic limb paresis and fecal and urinary incontinence. MRI demonstrated an extradural, ovoid mass compressing the lumbar spinal cord. Surgical excision of the mass was performed. Histologically, the mass was consistent with hemangiosarcoma with no involvement of the adjacent vertebrae. The dog underwent a doxorubicin-based chemotherapy protocol with the addition of oral cyclophosphamide. After completion of chemotherapy, the dog was evaluated q 4 mo for restaging. Clinicopathological evidence of primary tumor recurrence or metastatic disease was not detected for 15 mo after initial diagnosis and treatment. To the authors' knowledge, this is the first report of a primary extradural hemangiosarcoma in the lumbar vertebral column in a dog. The clinical presentation, diagnosis, treatment, and outcome are also discussed. PMID:25955146

    Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

    A 68-year-old woman, complained of an indolent lump about 60 × 70 mm in size in the left lower back. We conducted a computed tomography scan, which exhibited a hernia of Gerota'sfascia-commonly called superior lumbar hernia. In the right lateral position, the hernia contents were observed to attenuate, hence only closure of the hernial orifice was conducted by using Kugel patch, without removal of the hernia sack. Six months after the surgery, she has had no relapse of the hernia. Superior lumbar hernia, which occurs in an anatomically brittle region in the lower back, is a rare and potentially serious disease. The urologic surgeon should bear in mind this rarely seen entity.

  16. Laparoscopic transabdominal extraperitoneal repair of lumbar hernia

    Directory of Open Access Journals (Sweden)

    Sharma A

    2005-01-01

    Full Text Available Lumbar hernias need to be repaired due to the risk of incarceration and strangulation. A laparoscopic intraperitoneal approach in the modified flank position causes the intraperitoneal viscera to be displaced medially away from the hernia. The creation of a wide peritoneal flap around the hernial defect helps in mobilization of the colon, increased length of margin is available for coverage of mesh and more importantly for secure fixation of the mesh under vision to the underlying fascia. Laparoscopic lumbar hernia repair by this technique is a tensionless repair that diffuses total intra-abdominal pressure on each square inch of implanted mesh. The technique follows current principles of hernia repair and appears to confer all benefits of a minimal access approach.

  17. Clinical trial of iohexol in lumbar myelography

    International Nuclear Information System (INIS)

    Iohexol containing 180 mg I/ml was used in 20 patients for lumbar myelography. By using an adequate volume up to a maximum of 15 ml, satisfactory films were obtained in all cases. Minor or moderate adverse effects occurred in 4 patients. There were no changes in vital signs or neurologic examination related to the examinations. No patient had difficulty with concentration, personality changes or seizures. Later encephalographies performed in all patients before and during 24 h after the iohexol injections, showed no seizure or abnormal activity or any significant change. Repeated lumbar puncture was performed in 9 patients 24 h after the injection of iohexol. One of these, a patient with symptoms due to disc prolapse, whose CSF was abnormal before the myelography, had a slightly increased cellular response. There was no significant change in any of the other patients. Iohexol is a very satisfactory contrast medium for myelography and compared favorably with other non-ionic contrast media. (Auth.)

    Revision lumbar spine surgeries are technically challenging with inconstant outcome results. This article discusses the preoperative, intraoperative, as well as postoperative management in these difficult patients. Successful intervention requires a detailed history and physical examination and carefully chosen diagnostic tests. Preoperative planning is paramount in these cases. The decision-making process should address the timing of the surgery, surgical approach, level of interbody fusion ...

    Lumbar spine disc herniations in children are a relatively rare condition reported to occur in less than 3% of those presenting with low back pain. Unlike the adult, the etiology and clinical picture often provides few clues to making the diagnosis. Although conservative management is the treatment of choice, surgical intervention may be required in some cases. The role of spinal manipulation in these cases may be of limited value. A case report is presented that illustrates the difficulty in...

    Lumbar hernias need to be repaired due to the risk of incarceration and strangulation. A laparoscopic intraperitoneal approach in the modified flank position causes the intraperitoneal viscera to be displaced medially away from the hernia. The creation of a wide peritoneal flap around the hernial defect helps in mobilization of the colon, increased length of margin is available for coverage of mesh and more importantly for secure fixation of the mesh under vision to the underlying fascia.

  10. Lumbar myelography in 79 dogs, using different puncture sites

    International Nuclear Information System (INIS)

    Lumbar myelography was performed in 79 dogs either before spinal surgery or as part of an investigation of neurological disease. In small dogs the site of the puncture was between L1 and L5, avoiding the lumbosacral intumescence, whereas in large dogs the site was between T13 and L2. It was found that a lumbar puncture cranial to the lumbar intumescence was easier and caused no problems. The lumbar puncture was unsuccessful in three obese dogs. In 72 per cent of the cases the myelogram revealed a lesion, and the main cause of a non-diagnostic myelogram was epidural leakage

  12. Skin to posterior lumbar epidural space distance

    International Nuclear Information System (INIS)

    To measure the clinically relevant skin to posterior lumbar epidural space distance in adult surgical patients and to correlate this distance with the patient physical factors to construct a model for the prediction of this distance using the correlation. The study was carried out in 100 patients divided into three groups, who were scheduled for different surgical procedures. Group-I consisted of female patients scheduled for lower segment caesarian section (L.S.C.S); group-II adult non-pregnant females undergoing elective surgery and group-III adult males undergoing different surgical procedures. Epidural anaesthesia was given, using loss of resistance (LOR) technique, and skin to posterior epidural space was measured. The mean skin to posterior lumbar epidural space distance was found to be 3.8 +- 0.5 cm in group-I, 3.76 +- 0.7 cm in group- II and 4.0 +- 0.5 cm in group-III. Skin to posterior epidural space distance correlates best with weight of the patient. Posterior lumbar skin to epidural space distance has been found to be less than what is normal in rest of the world. These results may be used as a guideline for performing successful epidural blocks in Pakistani population. A reliable model using patient physical factors to predict skin to posterior epidural space distance could not be constructed. (author)

    Chemonucleolysis is an advantageous alternative to surgical treatment of lumbar disc herniation. To achieve the best results the indications must be strictly observed and the procedure itself must be technically perfect. In these circumstances a rapid, non-invasive and less expensive treatment of lumbar disc herniation is possible.

    In this study, effectiveness of computed tomography (CT) in diagnosing lumbar disc herniation was evaluated. Twenty CT examinations which were interpreted as positive for a herniated disc, and were comfirmed by myelography, were reviewed. In 19 patients, CT demonstrated posterior protrusion of the disc but in one normal disc. Three typical cases were described. This study suggests that CT accurately demonstrates lumbar disc herniation.

    PurposeTo describe the radiologic findings and imaging response of hepatocellular carcinoma (HCC) supplied by the lumbar artery.MethodsBetween April 2004 and December 2012, we encountered HCC supplied by a lumbar artery in 21 patients. Two investigators retrospectively reviewed clinical and radiological findings of HCC supplied by the lumbar artery using computed tomography (CT) scans and digital subtraction angiograms.ResultsPatients had received 1–27 sessions of previous chemoembolization procedures (mean 7.7 sessions, median 4 sessions). Mean tumor size was 5.3 cm. The locations of HCC supplied by lumbar artery were the bare area (n = 14, 67 %) and segment VI (n = 7, 33 %). Tumor-feeding arteries arose from the main lumbar artery (n = 7), proximal anterior division (n = 4), and distal anterior division (n = 14). In 20 patients, selective chemoembolization through the tumor-feeding arteries of the lumbar artery was achieved. In 1 patient, nonselective embolization at the main lumbar artery was performed. There was no complication such as skin necrosis or paralysis. On the first follow-up enhanced CT scan, target tumors fed by the lumbar artery showed complete response (n = 6), partial response (n = 4), stable disease (n = 3), and progressive disease (n = 8), but overall tumor response was partial response (n = 1) and progressive disease (n = 20).ConclusionWhen HCC is located in the inferior tip or bare area of the liver, a lumbar artery may supply the tumor. Although selective chemoembolization via the tumor-feeding vessel of the lumbar artery can be achieved in most cases, overall tumor response is commonly unfavorable.

    Ischemic optic neuropathy is the most common cause of visual complications after non-ophthalmic surgery. The incidence has varied in different case series, but prone-position spine surgery appears to be involved in most of the reports. We present the case of a 47-year-old woman who developed near total blindness in the left eye following lumbar spine fusion surgery involving the loss of 900 mL of blood. An ophthalmic examination including inspection of the ocular fundus, fluorescein angiography, and visual evoked potentials returned a diagnosis of retrolaminar optic neuropathy. Outcome was poor.

  6. Lumbar spine degenerative disease : effect on bone mineral density measurements in the lumbar spine and femoral neck

    International Nuclear Information System (INIS)

    To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eight-six patient remained after excluding women less than 40 years of age (n=18) and those with hip osteoarthritis, scoliosis, lumbar spine fractures, lumbar spinal instrumentation, hip arthroplasty, metabolic bone disease other than osteoporosis, or medications known to influence bone metabolism (n=101). On the basis of lumbar spine radiographs, those with absent/mild degenerative disease were assigned to the control group and those with moderate/severe degenerative disease to the degenerative group. Spine radiographs were evaluated for degenerative disease by two radiologists working independently; discrepant evaluations were resolved by consensus. Lumbar spine and femoral neck bone mineral density was compared between the two groups. Forty-five (24%) of 186 women were assigned to the degenerative group and 141 (76%) to the control group. IN the degenerative group, mean bone mineral density measured 1.075g/cm? in the spine and 0.788g/cm2 in the femoral neck, while for controls the corresponding figures were 0.989g/cm2 and 0.765g/cm2. Adjusted for age, weight and height by means of analysis of variance, degenerative disease of the lumbar spine was a significant predictor of increased bone mineral density in the spine (p=0.0001) and femoral neck (p=0.0287). Our results indicate a positive relationship between degenerative disease of the lumbar spine and bone mineral density in the lumbar spine and femoral neck, and suggest that degenerative disease in that region, which leads to an intrinsic increase in bone mineral density in the femoral neck, may be a good negative predictor of osteoporotic hip fractures

    2016-06-01

    Sacral insufficiency fractures (SIFs) are a common cause of back pain in the elderly. SIFs mimic the symptoms of lumbar spine pathology and so are commonly missed or underdiagnosed. Here we present four cases of missed SIFs that were subsequently identified and treated. One patient was treated as mechanical lower back ache, another patient underwent root block and two patients underwent surgery for lumbar canal stenosis. None experienced relief of their symptoms after these procedures. Retrospective analysis of X-ray and magnetic resonance imaging data revealed SIFs that were confirmed by computed tomography scans. All four patients were treated for underlying osteoporosis. Two patients who underwent surgery were treated conservatively and other two were treated by sacroplasty involving injection of cement into the fracture. Sacroplasty produced immediate pain relief and early mobilization compared to the conservative group. SIFs should always be considered in the differential diagnosis of an elderly patient presenting with low back symptoms. Sacroplasty can be considered for immediate pain relief and rapid mobilization.

  8. Conjoined nerve root of the lumbar spine

    International Nuclear Information System (INIS)

    There have been a number of reports on lumbosacral nerve root anomalies. Among the most common of these anomalies is the conjoined nerve root. However, it is difficult to diagnose this condition preoperatively. We review the records of 142 patients who underwent microendoscopic discectomy (MED) for herniation of the lumbar disc. All patients had undergone magnetic resonance imaging (MRI) of the lumbar spine before surgery. For most patients, only sagittal and axial images were obtained; coronal images were obtained in only a minority of the patients. Postoperative coronal images were obtained in patients with conjoined nerve roots. A diagnosis of conjoined nerve roots was made intraoperatively in 4 patients; this diagnosis had not been possible preoperatively. After surgery, new coronal images were obtained for the 4 patients with conjoined nerve roots; however, there was no evidence of the condition on the new images. The surgical procedure employed was endoscopic decompression and herniotomy. The results were favorable, even though pediculotomy was not performed. It is difficult to diagnose nerve root anomalies preoperatively. However, the possibility of nerve root anomalies should always be considered during surgery to ensure a safe procedure, without intraoperative occurrence of nerve root injury. (author)

  9. Collateral Adverse Outcomes After Lumbar Spine Surgery.

    Daniels, Alan H; Gundle, Kenneth; Hart, Robert A

    2016-01-01

    Collateral adverse outcomes are the expected or unavoidable results of a procedure that is performed in a standard manner and typically experienced by the patient. Collateral adverse outcomes do not result from errors, nor are they rare. Collateral adverse outcomes occur as the direct result of a surgical procedure and must be accepted as a trade-off to attain the intended benefits of the surgical procedure. As such, collateral adverse outcomes do not fit into the traditional definition of a complication or adverse event. Examples of collateral adverse outcomes after lumbar spine arthrodesis include lumbar stiffness, postoperative psychological stress, postoperative pain, peri-incisional numbness, paraspinal muscle denervation, and adjacent-level degeneration. Ideally, a comparison of interventions for the treatment of a clinical condition should include information on both the negative consequences (expected and unexpected) and potential benefits of the treatment options. The objective evaluation and reporting of collateral adverse outcomes will provide surgeons with a more complete picture of invasive interventions and, thus, the improved ability to assess alternative treatment options.

    The lumbar facet disease is a frequently overlooked cause of sciatic pain, but the lumbar facet joints are well-recognized source of low back pain and radiating leg pain which can be confused with sciatica due to herniated disc. We measured the angulation of the facet joints on axial spine CT films in 149 cases which contains 41 normal group and 108 abnormal group and studied the relationship between the angulation and degeneration of the facets, the asymmetry of each sided facets and facet degeneration, the asymmetry and disc protrusion, and the asymmetry and annular bulging of the disc. The results were as follows: 1. Facet angulation in abnormal group were more sagittally oriented than the normal group. 2. The angulation of right facet was more sagittally oriented than the left in L4-5 level of abnormal group. 3. Degeneration of facet joints occur asymmetrically, and the more facet joint degenerates, the more it orients sagittally, particularly in L4-5. 4. Asymmetry in facet joint degeneration and unilateral disc protrusion of L5-SI level is greater than the normal gro0008.

    Lumbar degenerative disc disease is extremely common. Current evidence supports surgery in carefully selected patients who have failed non-operative treatment and do not exhibit any substantial psychosocial overlay. Fusion surgery employing the correct grafting and stabilization techniques has long-term results demonstrating successful clinical outcomes. However, the best approach for fusion remains debatable. There is some evidence supporting the more complex, technically demanding and higher risk interbody fusion techniques for the younger, active patients or patients with a higher risk of non-union. Lumbar disc arthroplasty and hybrid techniques are still relatively novel procedures despite promising short-term and mid-term outcomes. Long-term studies demonstrating superiority over fusion are required before these techniques may be recommended to replace fusion as the gold standard. Novel stem cell approaches combined with tissue engineering therapies continue to be developed in expectation of improving clinical outcomes. Results with appropriate follow-up are not yet available to indicate if such techniques are safe, cost-effective and reliable in the long-term. PMID:27559465

    This study was a retrospective analysis of 850 lumbar microdiscectomy (LMD) under epidural anesthesia (EA; n=573) or general anesthesia (GA; n=277) performed by the same surgeon and paid by invoice to the Social Security Institution of the Turkish Republic between April 2003 and May 2013. Although GA is the most frequently used method of anesthesia during LMD, the choice of regional anesthetia (epidural, spinal or a combination of these) differs between surgeons and anesthetists. Studies have reported that EA in surgery for lumbar disc herniation may be more reliable than GA, as it enables the surgeon to communicate with the patient during surgery, but few studies have compared the costs of these two anesthetic methods in LMD. We found that EA patient costs were significantly lower than GA patient costs (p0.05). The anesthetic method used during LMD affected the complication rate, cost and efficiency of operating room use. We suggest that EA is an anesthetic method that can contribute to health care cost savings and enable LMD to be completed with less nerve root manipulation and more comfort, efficacy, reliability and cost efficiency without affecting the success rate of the surgical procedure.

    Full Text Available Background: The details of lumbar disk hernia are specifically described in imaging studies, which leads to very specific diagnosis contributing to its appropriate treatment. Objective: To characterize through imaging studies the lumbar disk hernia in operated patients. Methods: Descriptive observational, correlational, retrospective study of a series of cases, carried out in the University Hospital “Dr. Gustavo Aldereguía Lima” of Cienfuegos, from 2000 to 2005, including all the patients who required imaging studies for a suspect of lumbar disk hernia, who received surgical treatment in that institution. The available imaging means were used: spine simple radiography in lumbar area, myelography and computerized axial tomography. Results: Males were more affected by lumbar disk hernia. The most common sings observed through spine simple radiography in lumbar area were: decrease of the intervertebral space and arthrosic changes in the vertebral bodies. Myelography was performed in six patients and three of them were positive. The most common kind of hernia according with their localization was the lateral, and according with the amount of herniated material, the protruded hernia. The most affected spaces were: L5- S1 and L4-L5. The patients of the third and fourth decade of life were the most affected, with a prevalence of the protruded hernia in the L5-S1 y L4 -L5 spaces. Conclusions: The imaging studies contributed to a correct characterization of lumbar disk hernia.

    Study Design Systematic review. Objectives (1) To compare the quality of adverse event (AE) methodology and reporting among randomized trials comparing lumbar fusion with lumbar total disk replacement (TDR) using established AE reporting systems; (2) to compare the AEs and reoperations of lumbar spinal fusion with those from lumbar TDR; (3) to make recommendations on how to report AEs in randomized controlled trials (RCTs) so that surgeons and patients have more-detailed and comprehensive information when making treatment decisions. Methods A systematic search of PubMed, the Cochrane collaboration database, and the National Guideline Clearinghouse through May 2015 was conducted. Randomized controlled trials with at least 2 years of follow-up comparing lumbar artificial disk replacement with lumbar fusion were included. Patients were required to have axial or mechanical low back pain of ≥3 months' duration due to degenerative joint disease defined as degenerative disk disease, facet joint disease, or spondylosis. Outcomes included the quality of AE acquisition methodology and results reporting, and AEs were defined as those secondary to the procedure and reoperations. Individual and pooled relative risks and their 95% confidence intervals comparing lumbar TDR with fusion were calculated. Results RCTs demonstrated a generally poor description of methods for assessing AEs. There was a consistent lack of clear definition or grading for these events. Furthermore, there was a high degree of variation in reporting of surgery-related AEs. Most studies lacked adequate reporting of the timing of AEs, and there were no clear distinctions between acute or chronic AEs. Meta-analysis of the pooled data demonstrated a twofold increased risk of AEs in patients having lumbar fusion compared with patients having lumbar TDR at 2-year follow-up, and this relative risk was maintained at 5 years. Furthermore, the pooled data demonstrated a 1.7 times greater relative risk of

  18. MRI manifestations of lumbar active inflammation in ankylosing spondylitis

    International Nuclear Information System (INIS)

    Objective: To study the MRI manifestations of lumbar active inflammation in ankylosing spondylitis (AS), and its relationship with CT grade of sacroiliitis. Methods: 64 cases of AS accepted lumbar MR scan with sagittal STIR/SPIR and T1-weighted fat suppressed sequences after administration of GD-DTPA. MR manifestations of lumbar active inflammation including active spondylitis, spondylodiskitis, arthritis of the facet joints and enthesitis were studied. Spondylitis was especially analyzed by Berlin method. 40 cases accepted CT scan of sacroiliac joints simultaneously, classed by modified New York criteria. Correlation: analysis was made between lumbar involvement and Berlin method. Results: There were 42 cases of active spondylitis, 6 of spondylodiskitis, 37 of arthritis of the facet joints, 32 of enthesitis in all 64 cases. The positive rate of lumbar involvement in AS was 85.9%. Positive rate of Spondylitis was 65.6%. L1/2 was 34.4%, which accounted for the most in all lumbar vertebral units, but there was not statistically significance between L1/2 and other Vertebral Units (P>0.05). The mean score of L5/S1 was 1.23, which was the highest in vertebral units involved, and there was statistically significance between L5/S1 and T12/L1, L1/2, L2/ 3 (P0.05) between lumbar active inflammation and the CT grades of sacroiliitis. Conclusions: Lumbar involvement of AS is common, mostly manifested as spondylitis, arthritis of the facet joints and enthesitis, with spondylodiskitis the least. In spondylitis, L1/2 is the most. There maybe no correlation between lumbar involvement and degree of spondylitis and grade of sacroiliitis. (authors)

    1982-01-01

    This study describes the prevalence, distribution, pathology and pathogenesis of lumbar interspinous bursitis (described as a clinical syndrome by Baastrup in 1933). It is based on an anatomic study of 152 lumbar spines derived from routine and random postmortem material, together with selected specimens from autopsies on patients with various rheumatic diseases. From a statistical study of 50 randomly chosen spines, bursae are found when the interspinous distance is small compared with the total height of the lumbar spine ('bursal index'): nearly all bursal spaces show some sign of inflammation and a few show severe bony erosion. Crystal deposits therein are also described. PMID:7178764

    Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia

    Full Text Available Lumbar hernias are uncommon and are reported rarely, they are informed only few more than 300 in literature and of them only 10 cases are congenital. The hernias that are produced through the superior lumbar space or Grynfelt-Lesshalf´s hernia, are due to the fact that they are more constant and larger they are usually more frequent than the Petit triangle. We are reporting a Newborn infant with the diagnosis of bilateral lumbar hernias and malformation of the vertebral column.

    A surgeon will rarely see a case of lumbar hernia in his lifetime. They are usually divided into superior and inferior types, but in cases of huge hernias where anatomical delineation is not possible, they are called as diffuse. Further classification into primary and secondary types (on the basis of etiology) and congenital and acquired types is done. Evisceration in a lumbar hernia can be present due to secondary causes but never spontaneously. This is therefore probably the first reported case of a primary eviscerated diffuse lumbar hernia.

  8. Lumbar spine radiography for osteoporosis via a staging system - CT densitometry of lumbar vertebrae

    International Nuclear Information System (INIS)

    Lumbar spine radiographs in 47 patients with manifest or clinically suspected osteoporosis were evaluated, using a staging system, and correlated to quantitative computed tomography (QCT) of lumbar vertebrae. The accuracy of osteoporosis assessment, obtained with plain film analysis, was 60%, the sensitivity 67%, the specificity 56%. Statistical correlation showed high standard deviation of each of the QCT-mean values according to the respective stage groups, and altogether poor linear correlation between increasing morphological stages of osteoporosis and decreasing QCT-values. As our results show plain film differentiation of normal from reduced trabecular bone mineral content is unreliable, even by use of a staging system. The diagnostic value of spine radiographs therefore remains limited to demonstration of advanced osteoporotic changes. (orig.)

    1996-05-01

    Lumbar stenosis has been well discussed recently, especially at the 64th French Orthopaedic Society (SOFCOT: July 1989). The results of different surgical treatments were considered as good, but the indications for surgical treatment were not clear cut. Laminectomy is not the only treatment of spinal stenosis. Laminectomy is an approach with its own rate of complications (dural tear, fibrosis, instability... ).Eight years ago, J. Sénégas described what he called the "recalibrage" (enlargement). His feeling was that, in the spinal canal, we can find two different AP diameters. The first one is a fixed constitutional AP diameter (FCAPD) at the cephalic part of the lamina. The second one is a mobile constitutional AP diameter (MCAPD) marked by the disc and the ligamentum flavum. This diameter is maximal in flexion, minimal in extension. The nerve root proceeds through the lateral part of the canal: first above, between the disc and the superior articular process, then below, in the lateral recess bordered by the pedicle, the vertebral body and the posterior articulation. With the degenerative change the disc space becomes shorter, the superior articular process is worn out with osteophytes. These degenerative events are complicated by inter vertebral instability increasing the stenosis. The idea of the "recalibrage" is to remove only the upper part of the lamina with the ligamentum flavum and to cut the hypertrophied anterior part of the articular process from inside. If needed the disc and other osteophytes are removed. The surgery is finished with a ligamentoplasty reducing the flexion and preventing the extension by a posterior wedge.Our experience in spine surgery especially in scoliosis surgery, showed us that it was possible to cure a radicular compression without opening the canal. The compression is then lifted by the 3D reduction and restoration of an anatomy as normal as possible. Lumbar stenosis is the consequence of a degenerative process. Indeed, hip

    Full Text Available There have been few studies comparing the clinical and radiographic outcomes between the Dynesys dynamic stabilization system and posterior lumbar interbody fusion (PLIF. The objective of this study is to compare the clinical and radiographic outcomes of Dynesys and PLIF for lumbar degenerative disease.Of 96 patients with lumbar degenerative disease included in this retrospectively analysis, 46 were treated with the Dynesys system and 50 underwent PLIF from July 2008 to March 2011. Clinical and radiographic outcomes were evaluated. We also evaluated the occurrence of radiographic and symptomatic adjacent segment degeneration (ASD.The mean follow-up time in the Dynesys group was 53.6 ± 5.3 months, while that in the PLIF group was 55.2 ± 6.8 months. At the final follow-up, the Oswestry disability index and visual analogue scale score were significantly improved in both groups. The range of motion (ROM of stabilized segments in Dynesys group decreased from 7.1 ± 2.2° to 4.9 ± 2.2° (P < 0.05, while that of in PLIF group decreased from 7.3 ± 2.3° to 0° (P < 0.05. The ROM of the upper segments increased significantly in both groups at the final follow-up, the ROM was higher in the PLIF group. There were significantly more radiographic ASDs in the PLIF group than in the Dynesys group. The incidence of complications was comparable between groups.Both Dynesys and PLIF can improve the clinical outcomes for lumbar degenerative disease. Compared to PLIF, Dynesys stabilization partially preserves the ROM of the stabilized segments, limits hypermobility in the upper adjacent segment, and may prevent the occurrence of ASD.

    Full Text Available OBJECTIVES: Hydrodiscectomy is a new technique used for percutaneous spinal discectomy that employs a high-intensity stream of water for herniated disc ablation and tissue aspiration. No previous clinical study has examined the effects of percutaneous hydrodiscectomy. The aim of this study is to evaluate the outcomes of hydrodiscectomy compared to open microdiscectomy regarding pain, function, satisfaction, complications and recurrence rates. METHODS: In this randomized clinical trial, patients referred to our tertiary hospital for lumbar back pain were recruited and included in the study if they had disc protrusion or small herniation in only one level, without neurological deficits and with no resolution after six weeks of conservative treatment. One group underwent open microdiscectomy, and the other group underwent percutaneous microdiscectomy via hydrosurgery. Function was evaluated using the Oswestry Disability Index and pain was assessed using a visual analog scale. Evaluations were performed preoperatively, and then during the first week and at one, three, six and twelve months postoperatively. Personal satisfaction was verified. Clinicaltrials.gov: NCT01367860. RESULTS: During the study period, 20 patients were included in each arm and 39 completed one-year of follow-up (one patient died of unrelated causes. Both groups exhibited equal improvement on the visual analog scale and Oswestry evaluations after treatment, without any significant differences. The improvement in the lumbar visual analog scale score was not significant in the hydrodiscectomy group (p=0.138. The rates of infection, pain, recurrence and satisfaction were similar between the two groups. CONCLUSION: Percutaneous hydrodiscectomy was demonstrated to be as effective as open microdiscectomy for reducing pain. The rates of complications and recurrence of herniation were similar between groups. Patient satisfaction with the treatment was also similar between groups.

  18. Upright positional MRI of the lumbar spine

    International Nuclear Information System (INIS)

    Supine magnetic resonance imaging (MRI) is routinely used in the assessment of low back pain and radiculopathy. However, imaging findings often correlate poorly with clinical findings. This is partly related to the positional dependence of spinal stenosis, which reflects dynamic changes in soft-tissue structures (ligaments, disc, dural sac, epidural fat, and nerve roots). Upright MRI in the flexed, extended, rotated, standing, and bending positions, allows patients to reproduce the positions that bring about their symptoms and may uncover MRI findings that were not visible with routine supine imaging. Assessment of the degree of spinal stability in the degenerate and postoperative lumbar spine is also possible. The aim of this review was to present the current literature concerning both the normal and symptomatic spine as imaged using upright MRI and to illustrate the above findings using clinical examples

    2015-10-01

    One of the major clinical issues encountered after lumbar spinal fusion is the development of adjacent segment pathology (ASP) caused by increased mechanical stress at adjacent segments, and resulting in various radiographic changes and clinical symptoms. This condition may require surgical intervention. The incidence of ASP varies with both the definition and methodology adopted in individual studies; various risk factors for this condition have been identified, although a significant controversy still exists regarding their significance. Motion-preserving devices have been developed, and some studies have shown their efficacy of preventing ASP. Surgeons should be aware of the risk factors of ASP when planning a surgery, and accordingly counsel their patients preoperatively. PMID:26435804

    To compare the usefulness of dynamic contrast enhanced lumbar spine MR imaging with that of conventional delayed contrast enhanced MR imaging in the assessment of postoperative herniated lumbar disc. Forty-one postoperative herniated lumbar disc (HLD) lesions of 32 patients with back pain were examined with MR imaging (1.5T, Vision, Siemens, Germany). Five-phase dynamic 2D FLASH sagittal images (TR/TE = 118.1msec/4.1msec) were obtained every 19 seconds with a 4 minutes delayed image after contrast injection. As seen on delayed images, the discs were assessed as recurred, fibrosis, or no change. On dynamic images, the pattern of enhancement was evaluated as follows : Type 1 (no change in peripheral disc enhancement between the early and late phases) ; or Type 2 (minimal internal extension of marginal smooth enhancement during the late phase) ; or Type 3 (marked internal extension of peripheral irregular enhancement). Dynamic and delayed imaging were compared, and early epidural space enhancement with rapid wash-out was also evaluated. Of 41 postoperative HLDs, 39 lesions showed peripheral contrast enhancement. Evaluation depended on delayed imaging, and was as follows : recurred HLD (n=27) ; fibrosis (n=5) ; no change in postoperative disc (n=7). On dynamic contrast-enhanced imaging, enhancement patterns were Type 1 (n=29), Type 2 (n=7), and Type 3 (n=3). In 29 Type 1 lesions, there were no significant differences in image findings between dynamic and delayed images. However, in ten lesions (type 2 : n=7, type 3 : n=3), findings additional to those revealed by delayed images were demonstrated by dynamic contrast-enhanced MR imaging. Nine of the ten Type 2 and 3 lesions were diagnosed as recurred HLD. On dynamic images, five lesions showed early epidural space enhancement. Dynamic contrast-enhanced lumbar spine MR imaging provided additional findings such as increased peripheral disc enhancement, and epidural space enhancement, which cannot be detected on

    Full Text Available Abstract Introduction Lumbar hernia is a rare abdominal wall defect and clinical suspicion is necessary for diagnosis. Case presentation We report the case of a 40-year-old Caucasian woman with a superior lumbar hernia (Grynfeltt hernia initially misdiagnosed as a recurrent lipoma. The correct diagnosis was made intra-operatively and the hernia was repaired using synthetic mesh. The patient was free of recurrence at 4 months after the operation. Conclusion A lumbar or flank mass should always raise suspicion of a lumbar hernia. Ultrasound and computed tomography may confirm the diagnosis. Adequate surgical treatment should be planned on the basis of etiology and hernia size. Both open and laparoscopic techniques can be used with good results.

    The factors that affect lumbar stability have been an area of extensive research. The clinical application of this research in the form of lumbar stabilization exercise programs has become a common treatment of low back pain and is also increasingly used by athletes to improve performance and by the general public for health and the prevention of injury. This article includes a review of the key concepts behind lumbar stabilization. The literature regarding how those with low back pain differ in their ability to stabilize the spine from those without low back pain is discussed, and an overview of current research that assesses the benefits of a lumbar stabilization program to treat low back pain is provided.

Rehabilitation Research Centre; Helsinki Univ. (Finland). Dept. of Physical Medicine and Rehabilitation; Liverpool Univ. (UK). Dept. of Orthopaedic and Accident Surgery)

    Seven measures at the three lowest lumbar interspaces were recorded from conventional radiographs of the lumbar spines of 160 consecutive patients with low back pain and sciatica admitted for myelography and possible surgery. Eighty-eight patients were operated upon for disc herniation, and of the conservatively-treated 72 patients, 18 had a pathologic and 54 a normal myelogram. The results were evaluated after one year using the occupational handicap scales of WHO. Correlations of radiographic measures to stature were moderate and to age small. After adjusting for stature and age, only the male interpedicular distances and the antero-posterior diameter of intervertebral foramen at L3 were greater than those of females. The males with a pathologic myelogram had smaller posterior disc height at L3 and a smaller interarticular distance at L3 and L4 than those with normal myelogram, likewise the midsagittal diameter at L3 and L4 in females. In all patients other measures besides posterior disc height were smaller than those for low back pain patients (p<0.001) or for cadavers (p<0.001). The only correlation between measures and clinical manifestations was between pedicular length at L3 and limited straight leg raising. Where the disc material had been extruded into the spinal canal, the interpedicular distance was significantly wider. Only anterior disc height at L3 revealed differences between good and poor outcome one year after surgery, as did the interarticular distance at S1 in patients with normal myelogram after conservative treatment.

    2009-04-01

    Full Text Available Background: Piriformis syndrome (PS, a rare cause of sciatica, is usually diagnosed onlyafter excluding all other possibilities. But this principle is being challengedbecause of the number of patients with PS who have had ineffective lumbardecompressive surgery after positive findings on image study.Methods: From 2001 to 2004, twelve patients with piriformis syndrome diagnosed byphysical examination were retrospectively enrolled in this study. Indicatorsof piriformis syndrome include a positive Freiberg sign and local tendernessover the piriformis tendon. All patients received local injection of triamcinoloneacetonide and lidocaine into the piriformis tendon. The course ofdiagnosis and treatment was reviewed retrospectively from patient recordsand patient recollections.Results: Of seven (58.3% patients who had positive findings on computed tomography(CT or magnetic resonance imaging (MRI studies of the lumbar spine,four had previously undergone unsuccessful lumbar surgeries but wereresponsive to local injection and three received the injection first. Two ofthose three required no lumbar discectomy thereafter. However, one patientsubsequently underwent lumbar decompression surgery because of failedresponse to the local injection. Three patients had negative CT or MRI findings,and two received no CT or MRI study. According to our diagnosticflowchart for PS, further lumbar surgery was unnecessary for eleven of thetwelve patients at follow-up.Conclusions: According to experience in this series, a Freiberg test and local injectionshould be performed first to rule out PS in patients with unilateral sciatica. Ifsymptoms are relieved by local injection and further physical therapy for PS,unnecessary lumbar surgery can be avoided.

  9. Ossification of the posterior longitudinal ligament of the lumbar spine

    International Nuclear Information System (INIS)

    The ossification on the cervical posterior longitudinal ligament (OPLL) is widely known and studied in Japan where a roentgenological incidence of 2.6% adults affected has been found. Data concerning the ossification of the lumbar posterior longitudinal ligament are few and occasional. An epidemiological survey on lumbar OPLL was performed by the authors in Matsumoto, Japan, on a total of 972 subjects, 554 of whom over the age of 35, by means of X-ray of the lumbar spine. Ossification of the lumbar posterior longitudinal ligament was detected in 23 subjects (2.9%), with no significant difference between males (3.0%) and females (2.8). Lumbar OPLL was absent in the 238 subjects aged less than 34; it was most prevalent after the age of 45 (5.1% in males and 4.5% in females). The ossification developed in two ways: continuous ossified layer extending over several vertebrae; circumscribed ossification of the ligament corresponding to the level of the invertebral disk (retrodiscal type). The results of this epidemiological survey showed a roentgenological incidence of lumbar OPLL of the same magnitude than that of cervical OPLL

    Beneck, George J; Story, John W; Donald, Shelby

    2016-04-01

    Study Design Controlled laboratory study, repeated-measures design. Background Diminished multifidus activation and cross-sectional area are frequent findings in persons with low back pain. Increasing lumbar lordosis has been shown to increase activation of the multifidus with a minimal increase in activation of the long global extensors during unsupported sitting. Objectives To examine the influence of postural cueing to increase lumbar lordosis on lumbar extensor activation during trunk stabilization exercises. Methods Thirteen asymptomatic participants (9 male, 4 female) were instructed to perform 6 trunk stabilization exercises using a neutral position and increasing lumbar lordosis. Electrical activity of the deep multifidus and longissimus thoracis was recorded using fine-wire intramuscular electrodes. The mean root-mean-square of the electromyography (EMG) signal obtained during each exercise was normalized to a maximum voluntary isometric contraction (MVIC). A 2-way, repeated-measures analysis of variance (posture by exercise) was performed for each muscle. Results When averaged across the 6 exercises, postural cueing to increase lumbar lordosis resulted in greater multifidus EMG activity compared to performing the exercises in a neutral posture (35.3% ± 15.1% versus 29.5% ± 11.2% MVIC). No significant increase in longissimus thoracis EMG activity was observed when exercising with cueing to increase lumbar lordosis. Conclusion This study suggests that postural cueing to increase lumbar lordosis during trunk stabilization exercises may better promote multifidus activation than traditional stabilization exercises alone. Future studies are needed to determine whether increasing lumbar lordosis improves multifidus activation in persons with low back pain. J Orthop Sports Phys Ther 2016;46(4):293-299.

    Although the lumbar spine region is the most common site of injury in golfers, little research has been done on intervertebral loads in relation to the anatomical-morphological differences in the region. This study aimed to examine the biomechanical effects of anatomical-morphological differences in the lumbar lordosis on the lumbar spinal joints during a golf swing. The golf swing motions of ten professional golfers were analyzed. Using a subject-specific 3D musculoskeletal system model, inverse dynamic analyses were performed to compare the intervertebral load, the load on the lumbar spine, and the load in each swing phase. In the intervertebral load, the value was the highest at the L5-S1 and gradually decreased toward the T12. In each lumbar spine model, the load value was the greatest on the kypholordosis (KPL) followed by normal lordosis (NRL), hypolordosis (HPL), and excessive lordosis (EXL) before the impact phase. However, results after the follow-through (FT) phase were shown in reverse order. Finally, the load in each swing phase was greatest during the FT phase in all the lumbar spine models. The findings can be utilized in the training and rehabilitation of golfers to help reduce the risk of injury by considering individual anatomical-morphological characteristics. PMID:25162173

    AIM: To investigate the diagnostic validity and therapeutic value of lumbar facet joint interventions in managing chronic low back pain. METHODS: The review process applied systematic evidence-based assessment methodology of controlled trials of diagnostic validity and randomized controlled trials of therapeutic efficacy. Inclusion criteria encompassed all facet joint interventions performed in a controlled fashion. The pain relief of greater than 50% was the outcome measure for diagnostic accuracy assessment of the controlled studies with ability to perform previously painful movements, whereas, for randomized controlled therapeutic efficacy studies, the primary outcome was significant pain relief and the secondary outcome was a positive change in functional status. For the inclusion of the diagnostic controlled studies, all studies must have utilized either placebo controlled facet joint blocks or comparative local anesthetic blocks. In assessing therapeutic interventions, short-term and long-term reliefs were defined as either up to 6 mo or greater than 6 mo of relief. The literature search was extensive utilizing various types of electronic search media including PubMed from 1966 onwards, Cochrane library, National Guideline Clearinghouse, clinicaltrials.gov, along with other sources including previous systematic reviews, non-indexed journals, and abstracts until March 2015. Each manuscript included in the assessment was assessed for methodologic quality or risk of bias assessment utilizing the Quality Appraisal of Reliability Studies checklist for diagnostic interventions, and Cochrane review criteria and the Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment tool for therapeutic interventions. Evidence based on the review of the systematic assessment of controlled studies was graded utilizing a modified schema of qualitative evidence with best evidence synthesis, variable from level I to level V

Various modalities of treatments are utilized in managing discogenic and axial low back pain including epidural injections. However, there is a paucity of evidence regarding the effectiveness, indications, and medical necessity of any treatment modality utilized for managing axial or discogenic pain, including epidural injections. In an interventional pain management practice in the US, a randomized, double-blind, active control trial was conducted. The objective was to assess the effectiveness of lumbar interlaminar epidural injections of local anesthetic with or without steroids for managing chronic low back pain of discogenic origin. However, disc herniation, radiculitis, facet joint pain, or sacroiliac joint pain were excluded. Two groups of patients were studied, with 60 patients in each group receiving either local anesthetic only or local anesthetic mixed with non-particulate betamethasone. Primary outcome measures included the pain relief-assessed by numeric rating scale of pain and functional status assessed by the, Oswestry Disability Index, Secondary outcome measurements included employment status, and opioid intake. Significant improvement or success was defined as at least a 50% decrease in pain and disability. Significant improvement was seen in 77% of the patients in Group I and 67% of the patients in Group II. In the successful groups (those with at least 3 weeks of relief with the first two procedures, the improvement was 84% in Group I and 71% in Group II. For those with chronic function-limiting low back pain refractory to conservative management

  18. Magnetic resonance imaging of normal lumbar intervertebral discs

    International Nuclear Information System (INIS)

    Objective was to study changes in midpoint lumbar disc heights in an asymptomatic Jordanian sample relative to age, sex, lumbar level and midvertebral heights. A total of 153 asymptomatic patients (87 males, age range 20-65 years; mean 43+/-12.1 and 66 females, age range 22-68 years; mean 47+/-13.7) were selected during the study period. All underwent midsagittal magnetic resonance imaging to measure the midpoint disc height and midvertebral height of all lumbar spines. Values were statistically analyzed to obtain the significance of differences in the means of midpoint disc heights at different levels in every age group and among other age groups. The relative height indices for every lumbar level in each age group for both males and females were determined. The results showed that a highly significant sex-independent cephalocaudal increase sequence of midpoint disc heights is evident, where maximum values are reached at lumbar 3/4 level in the younger age groups and at lumbar 5/sacral 1 level in older ones. In relation to age, midpoint disc heights displayed a non-linear, alternating increase/decrease pattern, which was of higher magnitude and statistically significant in males, but less evident and statistically insignificant in females. Maximum values were reached during the 6th decade in males while during the 5th decade in females. The relative height indices were similar in both sexes and remained fairly constant between age groups at all levels. The craniocaudal and age-dependent patterns could be termed physiological and interpreted as adaptation of the lumbar spine to changing functional demands. The utility of the relative height index is discussed. (author)

    Full Text Available Abstract Background No prior studies have examined systematic bias in the musculoskeletal physical examination. The objective of this study was to assess the effects of bias due to prior knowledge of lumbar spine magnetic resonance imaging findings (MRI on perceived diagnostic accuracy of the physical examination for lumbar radiculopathy. Methods This was a cross-sectional comparison of the performance characteristics of the physical examination with blinding to MRI results (the 'independent group' with performance in the situation where the physical examination was not blinded to MRI results (the 'non-independent group'. The reference standard was the final diagnostic impression of nerve root impingement by the examining physician. Subjects were recruited from a hospital-based outpatient specialty spine clinic. All adults age 18 and older presenting with lower extremity radiating pain of duration ≤ 12 weeks were evaluated for participation. 154 consecutively recruited subjects with lumbar disk herniation confirmed by lumbar spine MRI were included in this study. Sensitivities and specificities with 95% confidence intervals were calculated in the independent and non-independent groups for the four components of the radiculopathy examination: 1 provocative testing, 2 motor strength testing, 3 pinprick sensory testing, and 4 deep tendon reflex testing. Results The perceived sensitivity of sensory testing was higher with prior knowledge of MRI results (20% vs. 36%; p = 0.05. Sensitivities and specificities for exam components otherwise showed no statistically significant differences between groups. Conclusions Prior knowledge of lumbar MRI results may introduce bias into the pinprick sensory testing component of the physical examination for lumbar radiculopathy. No statistically significant effect of bias was seen for other components of the physical examination. The effect of bias due to prior knowledge of lumbar MRI results should be considered

    Full Text Available The purpose of this paper is to show the importance and utility of swimming within rehabilitation and therapeutic programs for posture deficiencies, in our context for the rehabilitation of lumbar hyperlordosis. We consider that, by using exercises specific to swimming and means specific to acquiring swimming procedures, we will reduce the range of lumbar hyperlordosis. More precisely, we believe that, through exercises specific to swimming, we will reduce the range of lumbar hyperlordosis by at least 15 mm. Our study comprise three subjects (young girls, who suffer from lumbar hyperlordosis. For establishing the diagnostic, the following examinations and tests took place: anamnesis; somatoscopy; somatometry; muscular testing; specific tests (Schõber, “finger-floor”. The therapeutic program applied included the following: exercises for learning and consolidating the swimming procedures of crawl, backstroke, breaststroke and butterfly. The rehabilitation program lasted five months and a half; we had two sessions per week, each session of 35-40 minutes; water temperature ranged between 29 and 31 degrees Celsius. Initial testing showed that the lordosis amplitude was 70 mm for subject A.B., 60 mm for subject R.A. and 55 mm for subject S.A. At the end of research the results of the lordosis amplitude were 52 mm for subject A.B., 45 mm for subject R.A. and 40 mm for subject S.A. The conclusion of this study underlines that the early and correct intervention through individualized rehabilitation programs for lumbar hyperlordosis leads to a decrease in the lumbar curvature, down to physiological values. In addition, the means used for acquiring and consolidating swimming procedures can constitute important means in the rehabilitation process for lumbar hyperlordosis.

  1. Endoscopic posterior decompression of lumbar canal stenosis

    Full Text Available Lumbar canal stenosis (LCS is quite common. Surgery is indicated when patient fails to improve after conservative treatment. Endoscopic technique can be used in LCS and lateral recess stenosis. It can be performed in degenerative canal stenosis or with disc bulges. Bilateral severe bony canal stenosis and unstable spine are the contraindications. This procedure should be avoided in patients with a history of trauma. Detailed history and thorough physical examination should be performed to find out exact level of pathology responsible for symptoms. Patient′s symptoms must correlate with radiological findings. Magnetic resonance imaging is the investigation of choice because of its superior visualization of soft-tissue. Computed tomography scan does give a more accurate and detailed picture of the bony anatomy. Although the operative time and the complication rate could be more in the initial learning curve, the results of endoscopic decompression are comparable with conventional open procedures with the additional benefit of decreased complications and lower morbidity, when sufficient experience is gained. Complications in endoscopic surgery for LCS could be dural tears, hematomas and root and facet injury. This procedure is also associated with limitations such as steep learning curve and the contra lateral decompression may not be as good as ipsilateral side. Some of the limitations of this technique can be overcome by attending live operative workshop, practice on models and hands on cadaveric dissection. Conversion to an open procedure may be required when there is disorientation, management of dural tear and for control of bleeding.

    A descriptive study was carried out on patients admitted for febrile convulsion over a two-year period to determine rate of lumbar puncture (LP) refusal, factors associated with LP refusal and outcome of such patients. From 77 patients indicated and requested for LP, 19 (25%) patients refused the procedure. Refusal of LP was significantly more common among the Malay ethnic group (p = 0.01) but not significantly associated with age,gender or whether the patient was admitted for a first or recurrent febrile convulsion. Half of the patients who refused LP had to be started empirically on antibiotics for meningitis. Patients who refused LP were also 8.5 times more likely to discharge themselves "at own risk" (AOR), compared to other patients with febrile convulsion (p = 0.004). In conclusion, LP refusal is a common problem in the local setting and is a hindrance to the proper management of patients with fever and seizure. Appropriate measures must be carried out to educate the public, particularly those from the Malay ethnic group on the safety and usefulness of the procedure. Reasons for patients discharging AOR following LP refusal also need to be addressed and problems rectified. PMID:11281439

    A personal prospective study of 98 consecutive patients presenting with neurological impairment and fractures or dislocations between the 9th thoracic and 2nd lumbar vertebrae bodies. Fifty-three patients underwent Harrington instrumentation, and 45 patients were treated recumbently. Neurological improvement was much better following Harrington rods in the complete paraplegia group but there was no difference in neurological recovery between the two groups in those with incomplete paraplegia. Forty-two patients who had been stabilised with Harrington rods underwent post-operative myelography or tomography to assess the adequacy of spinal decompression. The best results were in patients with adequate neural canal decompression. In 21 cases decompression had not been adequate, usually due to a stereotyped pattern in which the postero-superior aspect of the fractured body remained in the neural canal. All 21 underwent anterior decompression at an average of five months post injury. All the incomplete anterior decompression at an average of five months post injury. All the incomplete paraplegics (nine patients) regained the ability to walk, three of the 12 complete paraplegics improved and regained the ability to walk with bilateral ankle-foot orthoses. Neurological improvement was dependent upon the adequacy of spinal cord decompression and not upon Harrington rods. per se. Harrington rods alone were not adequate to decompress the spinal canal in 50 per cent of cases. The best results after anterior decompression occurred where neural compression was caused by a minimally displaced wedge fracture distal to T12. PMID:4047711

  4. 3-D MRI for lumbar degenerative diseases

    International Nuclear Information System (INIS)

    Three-dimensional (3-D) magnetic resonance (MR) images obtained from 10 patients with lumbar degenerative diseases were retrospectively reviewed to determine how far 3-D MR imaging is capable of demonstrating nerve roots. In 8 of the 10 patients, the area up to the dorsal root ganglion was visualized on 3-D MR images. Thus, it is capable of detecting a wide area of nerve roots, thereby allowing the determination of running of nerve root, and size and location of dorsal root ganglion. In delineating the area from the dural canal to root cyst, 3-D MR imaging was equal to conventional myelography. The former was superior to the latter in detecting the positional relation between the degenerative intervertebral disc and the nerve root, and herniation-compressed root cyst. In 3 of 9 patients who presented with root symptoms, disturbed nerve roots were of high signal on 3-D MR images. This may suggest that it has the potential for selectively detecting root nerves associated with clinical manifestations. (N.K.)

    To assess multifidus muscle asymmetry using the cross-sectional area (CSA) and perpendicular distance of the multifidus muscle to the lamina (MLD) measurements in patients with nerve compression due to lumbosacral disc hernia. In total, 122 patients who underwent microdiscectomy for unilateral radiculopathy caused by disc herniation, diagnosed by magnetic resonance imaging (MRI), were evaluated retrospectively. Posterolateral or foraminal disc herniation at only one disc level, the L3-4, L4-L5, or L5-S1 region, was confirmed using MRI. Subjects were divided by symptom duration: 1-30 days, (group A), 31-90 days (group B), and > 90 days (group C). There were 48 cases in group A, 26 in group B, and 48 in group C. In groups A, B, and C, the median MLD differed significantly between the diseased and normal sides (P < 0.05). The MLD increased on the diseased side with symptom duration by lumbar disc herniation. The diseased side MLD was 5.1, 6.7, and 7.6 mm in groups A, B, and C, respectively (P < 0.05). The cut-off values for the MLD measurements were 5.3 mm (sensitivity = 62.3 %, specificity = 55.5 %; P < 0.05). In groups A, B, and C, the median CSA of the multifidus muscle was not significantly different between the diseased and the normal side (P > 0.05). The MLD measurement correlated significantly with multifidus asymmetry in patients with lumbar disc herniation. (orig.)

    International Nuclear Information System (INIS)

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery

    To date, no reports have presented radiculopathy secondary to heterotopic ossification following lumbar total disc arthroplasty. The authors present a previously unpublished complication of lumbar total disk arthroplasty (TDA) secondary to heterotopic ossification (HO) in the spinal canal, and they propose a modification to the McAfee classification of HO. The patient had undergone an L5/S1 lumbar TDA two years prior due to discogenic back pain. His preoperative back pain was significantly relieved, but he developed new, atraumatic onset radiculopathy. Radiographs and a computed tomography myelogram revealed an implant malposition posteriorly with heterotopic bone formation in the canal, causing an impingement of the traversing nerve root. Revision surgery was performed with implant extraction, L5/S1 anterior lumbar interbody fusion, supplemental posterior decompression, and pedicle screw fixation. The patient tolerated the procedure well, with complete resolution of the radicular leg pain. At a two-year follow up, the patient had a solid fusion without subsidence or recurrence of heterotopic bone. This case represents a novel pattern of heterotopic ossification, and it describes a previously unreported cause for implant failure in lumbar disc replacement surgery-reinforcing the importance of proper intraoperative component positioning. We propose a modification to the existing McAfee classification of HO after TDA with the addition of Class V and VI HO. PMID:26097664

    Because female gymnasts as a group display higher than average incidences of stress-related pathologies of the lumbar spine, it was of interest to evaluate mechanical factors which are potential contributors. Lumbar hyperextension and impact forces were quantified for performances of five commonly executed gymnastics skills by four competitive collegiate women gymnasts. The skills performed were the front walkover, the back walkover, and the front handspring, the back handspring, and the handspring vault. Wielke's (1983) radius method was used to quantify lumbar curvatures from film data during normal relaxed standing postures and during subject performances of the five selected skills. A force platform was used to monitor vertical and lateral ground reaction forces at the terminations of the respective skill performances. Of the skills examined, the handspring vault produced the highest vertical and lateral impact forces, and the back handspring and back walkover required the greatest amounts of lumbar hyperextension. During the front and back walkovers and during the back handspring, maximum lumbar hyperextension occurred very close to the time that impact force was sustained by either the hands or the feet.

    ObjectS. To investigate the biomechanical aspects of etiology, pathology, clinical manifestation, diagnosis and surgical treatment of the lumbar spinal stenosis. Methods. A series of biomechanical methods, such as three-dimensional finite element models, threedimensional kinematic measurement, cadeveric evaluation, and imaging assessment was applied to correlate lumbar biomechanics and lumber spinal stenosls. Surgery of lumber spinal stenosis has been improved. Results.The stresses significantly concentrate on the posterolateral part of the annulus fibrcsms of disc, the posterior surface of vertebral body, the pedlcle, the interarticularis and the beet joints. This trend is intensified by disc degeneration and lumber backward extension. Posterior elcxnent resection has a definite effect upon the biomechanical behavior of lumbar vertebrae. The improved operations proved satisfactory. Conclusion. Stress concentration in the lumber vertebrae is of importance to the etiology of degenerative lumbar spinal stenosls, and disc degeneratkm is the initial key of this process. Than these will be aggravatnd by backward extension. Functloval radiography and myelography are of assistance to the diagnosis of the lumhar spinal stenosls. For the surgcal treatment of the lumber spinal stenosis, destruction of the posterior element should be avoid as far as possible based upon the thorough decmnpression. Maintaining the lumbar spine in flexion by fusion after decorapression has been proved a useftd method. When developmental spinal stenoals is combined with disc herniation, discectoray through laminotomy is recommend for decompression.

    Intraspinal extradural synovial cysts are quite common in the lumbar spine. With respect to clinical presentation and surgical treatment, juxta-facet cysts (ganglion and synovial cysts) share identical characteristics and results. Nowadays, current treatment strategies of intraspinal juxta-facet cysts continue to inspire controversy regarding appropriate surgical approaches, and include many technical options. The purpose of this report is to illustrate the advantage of minimally invasive approaches in 3 cases of lumbar synovial cysts. We performed a small flavectomy in the 1st case, a transarticular partial facectomy, followed by etherologous bone graft fusion in the 2nd case, and a flavectomy and partial facectomy in the 3rd case. In our cases, a microsurgical approach to lumbar synovial cysts yielded to complete excision of the lesions and excellent pain relief, with early mobilization and hospital discharge of the patients. In our opinion, minimally invasive approaches and microsurgical excision of lumbar juxta-facet cysts are advantageous over conventional lumbar laminectomy because they reduce later development of segmental instability at the operative level, and therefore a less invasive strategy for intraspinal synovial cysts removal should be recommended.

    Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural elements, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension around nerve roots. Most patients with symptomatic lumbar stenosis had neurogenic intermittent claudication with the risk of a fall. However, although the physical findings and clinical symptoms in lumbar stenosis are not acute, the radiographic findings are comparatively severe. Magnetic resonance imaging is a noninvasive and good method for evaluation of lumbar stenosis. Though there are very few studies pertaining to the natural progression of lumbar spinal stenosis, symptoms of spinal stenosis usually respond favorably to non-operative management. In patients who fail to respond to non-operative management, surgical treatments such as decompression or decompression with spinal fusion are required. Restoration of a normal pelvic tilt after lumbar fusion correlates to a good clinical outcome. PMID:26435805

Los atractores mostraron la disminución de la complejidad ante estímulos autonómicos con respecto al estado basal. El análisis de la varianza (ANOVA, para la dimensión de correlación, no mostró diferencias significativas entre los estados neurovegetativos, basal 2.49 + 0.42, parasimpático 2.56 + 0.45 y simpático 2.43 + 0.38.

    Discusión: Existen reportes de una disminución en la variabilidad de la frecuencia cardíaca predispone a la presentación de arritmias cardíacas, muerte súbita e infarto agudo del miocardio. Así mismo, hay disminución de la complejidad del sistema respiratorio en la frecuencia cuando se presentan patologías. El Sistema nervioso simpático disminuye la complejidad y el sistema nervioso parasimpático la aumenta a nivel cardiovascular. En el presente estudio se encontró que los estímulos del sistema nervioso autónomo sobre la frecuencia respiratoria, disminuyen la variabilidad con respecto al estado basal, independientemente de si el estímulo es simpático o parasimpático. Lo anterior se evidencia por una disminución del cociente de variación, de la dimensión fractal y de los componentes espectrales; similar a lo encontrado en el sistema cardiovascular para

    Full Text Available BACKGROUND Spinal stenosis is one of the most common conditions in the elderly. It is defined as a narrowing of the spinal canal. The term stenosis is derived from the Greek word for narrow, which is “Stenos”. The first description of this condition is attributed to Antoine portal in 1803. Verbiest is credited with coining the term spinal stenosis and the associated narrowing of the spinal canal as its potential cause. [1-10] Kirkaldy–Willis subsequently described the degenerative cascade in the lumbar spine as the cause for the altered anatomy and pathophysiology in spinal stenosis. [11-15] If compression does not occur, the canal should be described as narrow but not stenotic. Some studies defined lumbar spinal stenosis as a “narrowing of the osteoligamentous vertebral canal and/or the intervertebral foramina causing compression of the thecal sac and/or the caudal nerve roots; at a single vertebral level, narrowing may affect the whole canal or part of it” (Postacchini 1983. This definition distinguished between disc herniation and stenosis. [16] . The most common type of spinal stenosis is caused by degenerative arthritis of the spine. Hypertrophy and ossification of the posterior longitudinal ligament which usually are confined to the cervical spine, and diffuse idiopathic skeletal hyperostosis (DISH syndrome also may result in an acquired form of spinal stenosis. Congenital forms caused by disorders such as achondroplasia and dysplastic spondylolisthesis are much less common. Congenital spinal stenosis usually is central and is evident or imaging studies. Idiopathic congenital narrowing usually involves the anteroposterior dimension of the canal secondary to short pedicles; the patient otherwise is normal. In contrast, in achondroplasia, the canal is narrowed in the anteroposterior plane owing to shortened pedicles and in lateral dimension because of diminished interpedicular distance. Acquired forms of spinal stenosis usually are

    Plain CT described fairly accurately the anatomy and lesions of the lumbar and sacral spines on their transverse sections. Since hernia of the intervertebral disc could be directly diagnosed by CT, indications of myelography could be restricted. Spinal-canal stenosis of the lumbar spine occurs because of various factors, and CT not only demonstrated the accurate size and morphology of bony canals, but also elucidated thickening of the joints and yellow ligament. CT was also useful for the diagnosis of tumors in the lumbar and sacral spines, visualizing the images of bone changes and soft tissues on the trasverse sections. But the diagnosis of intradural tumors required myelography and metrizamide CT. CT has become important for the diagnosis of spinal and spinal-cord diseases and for selection of the route of surgical arrival.

    Vascular complications of lumbar disc surgery are rare. Few cases have been reported. Arteriovenous fistulas are the most common. They are due to anatomical relationships between the last lumbar vertebrae, the corresponding discs, and the iliac vessels; degenerative lesions of the intervertebral discs facilitate instrumental vessel perforation, and operative difficulty. Computed tomography is particularly accurate for making the diagnosis. Treatment strategies consist in surgery or endovascular management. Percutaneous endovascular treatment using a stent-graft is a reasonable option for treating arteriovenous fistula. We describe the case of a 50-year-old patient who developed an iliocaval arteriovenous fistula following lumbar disc hernia surgery. The lesion was excluded by a stent-graft. The postoperative period was uneventful. PMID:26920402

Results: For patients failing six weeks of conservative care, the current literature supports surgical intervention or prolonged conservative management as appropriate treatment options for lumbar radiculopathy in the setting of disc herniation. Surgical intervention may result in more rapid relief of symptoms and restoration of function.Implementation: While surgery appears to provide more rapid relief, many patients will gradually get better with continued nonoperative management; thus, patient education and active participation in decision-making is vital.Keywords: lumbar disc, herniation, back pain, spine

    The purpose of this clinical study was to introduce technique for correct positioning of the needle into the center of the disc for discography by means of CT analysis and also to clarify usefulness of CT discography for diagnosis of the lumbar disc herniation. We have taken CT analysis in order to determine correct place and the angle of inserting the needle. This measurement provides easy needle insertion. Unless the needle tip places center of disc, discogram false positive or negative will occur as a result. The materials of this study are 222 discs of 105 cases with the lumbar disc herniation. Comparative study of the findings among myelography, discography and CT discography was investigated. The results indicated that CT discography demonstrates the most clear findings and is useful in the diagnosis of lumbar disc herniation, especially in obtaining detailed observation of herniated discs.

    Five cases of acute rupture of lumbar intervertebral disc caused by violent manipulation are reported. After protrusion of the lumbar intervertebral disc were treated by violent manipulation, the lumbo-leg pain were severe suddenly. The operations found that the annulus fibrosus had ruptured and the nerve root or cauda equina was constricted by the nucleus pulposus which had entered into the spinal canal. It must be emphasized that their is in danger of more damaging intervertebral disc degenerated by violent manipulation, then the adhesion of the nerve root will occur gradually. We don't suggest to make violent manipulation for the patient with the nerve root injured. We have acquired good results in treating protrusion of lumbar intervertebral disc by combined therapy and they are introduced in this article. PMID:2620603

    Experimental testing incorporating lumbar columns and isolated components is essential to advance the understanding of injury tolerance and for the development of safety enhancements. This study incorporated a whole column axial acceleration model and an isolated vertebral body model to quantify compression rates during realistic loading and compressive tolerance of vertebrae. Eight lumbar columns and 53 vertebral bodies from 23 PMHS were used. Three-factor ANOVA was used to determine significant differences (pmechanics between vertebral bodies obtained from males and females demonstrated non-significant trends, with female vertebral bodies having lower ultimate force that would be associated with decreased injury tolerance. This was likely a result of smaller vertebrae in that population. Combined with existing literature, results presented in this manuscript contribute to the understanding of lumbar spine tolerance during axial loading events that occur in both military and civilian environments with regard to effects of compression rate and gender.

    Full Text Available OBJECTIVES: To explore the microendoscopic discectomy technique and inclusion criteria for the treatment of recurrent lumbar disc herniation and to supply feasible criteria and technical notes to avoid complications and to increase the therapeutic effect. METHODS: A consecutive series of 25 patients who underwent posterior microendoscopic discectomy for recurrent lumbar disc herniation were included. The inclusion criteria were as follows: no severe pain in the lumbar region, no lumbar instability observed by flexion-extension radiography and no intervertebral discitis or endplate damage observed by magnetic resonance imaging. All patients were diagnosed by clinical manifestations and imaging examinations. RESULTS: Follow-up visits were carried out in all cases. Complications, such as nerve injuries, were not observed. The follow-up outcomes were graded using the MacNab criteria. A grade of excellent was given to 12 patients, good to 12 patients and fair to 1 patient. A grade of excellent or good occurred in 96% of cases. One patient relapsed 3 months after surgery and then underwent lumbar interbody fusion and inner fixation. The numerical rating scale of preoperative leg pain was 7.4± 1.5, whereas it decreased to 2.1±0.8 at 7 days after surgery. The preoperative Oswestry disability index of lumbar function was 57.5±10.0, whereas it was 26.0±8.5 at 7 days after surgery. CONCLUSION: In these cases, microendoscopic discectomy was able to achieve satisfactory clinical results. Furthermore, it has advantages over other methods because of its smaller incision, reduced bleeding and more efficient recovery.

    Pasi J Eskola

    Full Text Available OBJECTIVE: Low back pain is associated with lumbar disc degeneration, which is mainly due to genetic predisposition. The objective of this study was to perform a systematic review to evaluate genetic association studies in lumbar disc degeneration as defined on magnetic resonance imaging (MRI in humans. METHODS: A systematic literature search was conducted in MEDLINE, MEDLINE In-Process, SCOPUS, ISI Web of Science, The Genetic Association Database and The Human Genome Epidemiology Network for information published between 1990-2011 addressing genes and lumbar disc degeneration. Two investigators independently identified studies to determine inclusion, after which they performed data extraction and analysis. The level of cumulative genetic association evidence was analyzed according to The HuGENet Working Group guidelines. RESULTS: Fifty-two studies were included for review. Forty-eight studies reported at least one positive association between a genetic marker and lumbar disc degeneration. The phenotype definition of lumbar disc degeneration was highly variable between the studies and replications were inconsistent. Most of the associations presented with a weak level of evidence. The level of evidence was moderate for ASPN (D-repeat, COL11A1 (rs1676486, GDF5 (rs143383, SKT (rs16924573, THBS2 (rs9406328 and MMP9 (rs17576. CONCLUSIONS: Based on this first extensive systematic review on the topic, the credibility of reported genetic associations is mostly weak. Clear definition of lumbar disc degeneration phenotypes and large population-based cohorts are needed. An international consortium is needed to standardize genetic association studies in relation to disc degeneration.

  14. Spontaneous ligamentum flavum hematoma in the lumbar spine

    International Nuclear Information System (INIS)

    Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

    Osteoradionecrosis is a known complication following radiation therapy, presenting most commonly in the cervical spine as a delayed consequence of radiation that is often necessary in the management of head and neck cancers. In contrast, osteoradionecrosis has rarely been described in the lumbar spine. Here we describe, to our knowledge, the first reported case of lumbar spine osteoradionecrosis, after adjuvant radiation for a primary spinal cord tumor, leading to progressive degenerative scoliosis which required subsequent operative management. Established guidelines recommend that mature bone can tolerate a dose of up to 6000 cGy without injury. However, once bone has been exposed to radiation over this level progressive soft tissue changes may lead to devascularization, leaving the bone vulnerable to osteonecrosis, specifically when manipulated. Radiation necrosis can be progressive and lead to eventual mechanical instability requiring debridement and surgical fixation. In the setting of the lumbar spine, osseous necrosis can lead to biomechanical instability, deformity, pain, and neurologic deficit. PMID:27056674

    Assess the feasibility of 'dynamic' MRI of the lumbar spine and study the parameters of a single MRI sequence favorable for simultaneous imaging of the meningeal space and the epidural and foraminal venous system. Favor a decline in the number of sacco-radiculograms. Clinical assessment in the following circumstances: discordant clinical and and radiographic findings, difficulty in interpreting single or multiple disc-root conflicts, preoperative work-up in cases of narrow or stenotic lumbar canal. Dynamic MRI of the lumbar spine is possible if the hypothesis that the hyper-lordosis obtained in the supine position creates an anatomic and radiographic situation identical to the hyper-lordosis induced by the upright position is accepted. The 'radiculo-phlebographic' sequence gives images of the root sheaths and the epidural, foraminal and extra-foraminal veins simultaneously, particularly in the coronal plane. (authors)

  5. CT of postoperative lumbar disk herniation

    International Nuclear Information System (INIS)

    Results are reported of a multicenter analytic-statistical CT study on 128 postoperative lumbar herniated disk (HD) disk (HD) cases (50 at L4-L5, 64 at L5-S1, 2 at L3-L4, 12 multiple). CT was performed from 10 days to 204 months (47,7 months of mean) after surgery, in 51 patients without and in 77 with intravenous contrast medium (42 in bolus, 35 in perfusion). In 59 cases (38%) a recurrent hernia was found, and in 8% a new hernia. In 81% of patients epidural fibrous scars were demonstrated, in a rough 50% of cases associated with recurrent/new hernia: posterior fibrosis was found in 81% of cases, while unilaterally, bilaterally, or anteriorly extended fibroses were present in 20%, in 4,7%, and in 29% of cases respectively. In 72% of the patients injected with contrast medium, various kinds of fibrosis contrast enhancement were detected. In 8% neither fibrosis nor recurrent herniation was found. In 22% of cases lateral and/or central bony canal stenosis was present, in 26% vacuum disk, in 9% intracanalar calcifications, in 39% and in 19,5% dural sac stretching and compression respectively. In 5 cases a pseudomeningocele was found, and in 3 only a postoperative diskitis. Fibrosis is an almost inevitable postoperative consequence (4 out of 5 cases); it can be demonstrated by CT with high sensitivity and good specificity. A series of diagnostic criteria, such as the post-contrast media reaction, allow fibrosis to be discriminated from recurrent hernia. However, the possible association must be kept in mind of both diseases and/or of included roots in the scar. Myelography is hardly ever able to supply furthere resolutive diagnostic elements, while Myelo-CT sometimes more useful. The importance of bone changes is questionable, with the exception of evident cases of canal stenosis, also because in most cases the radiologist cannot count on a preoperative CT study. Furthermore, the correlation between CT and clinical findings (possible asymptomatic fibrosis) is often

    International Nuclear Information System (INIS)

    Among the patients operated because of lumbar disc herniation from January 1973 to May 1979 at Korea University Hospital, 154 cases were analyzed radiologically and the following conclusions were obtained. 1. The ratio of male to female was 1.96 : 1. 2. The incidences of single and multiple involvement were 74.7% and 25.3%. 3. Most frequent level of lumbar disc herniation was L4-5 interspace. 4. The incidences of left, central and bilateral defects were 45.45%, 33.76%, 12.33% and 8.44% respectively. 5. The incidences of spina bifida and transitional vertebra were 24.04% and 9.09% respectively. 6. The overall mean of the lumbosacral angle was 33.97 .deg. 7. The overall mean depth of the lumbar lordosis was 8.48 mm. 8. The ratio of the height of L4-5 interspace to the shorter anteroposterior diameter of L-5 body was obtained by authors' idea. The mean ratios of male and female patients of L4-5 disc herniation which had no evidence of the narrowing of L4-5 interspace on simple radiologic finding were 0.3042 and 0.3064 respectively. So the ratio had a little value in the diagnosis of L4-5 disc herniation on simple radiologic study. 9. Myelography had high diagnostic accuracy, and the majority of the pseudonegative finding on lumbar disc herniation myelographically was seen at L4-5 disc herniation.

    Full Text Available Background: thoraco-lumbar fractures may affect people at any moment of their lives, especially at their most fruitful and useful stage. Its correct diagnosis and treatment may directly influence in the posterior evolution of the patients. Objectives: to evaluate the results of the surgical treatment in thoraco-lumbar region fractures. Methods: a descriptive retrospective correlational study of series cases which included 54 patients attended due to thoraco-lumbar region fractures in the University Hospital “Dr. Gustavo Aldereguía Lima” in Cienfuegos city, Cuba from January 1999 to June 2007. Age, sex, etiology of the fracture, type and level of the fractures, associated diseases, surgical techniques used for, pre and post operatory neurological damage, usage of metilprednisolone, complications and final results were the variables taken into consideration in this study. Results: most of the patients belonged to male sex under the age of 45. The totality of the cases had type IV fracture, and a great part of them had Denis type II fracture having surgical treatment. The causes of the lesions were traffic accidents, working accidents and height falls. The most useful surgical techniques were posterior decompression, instrumentation and fusion. Surgery improved the neurological damage in almost half of sick patients with this condition. Complications were minimum and rupture of the implant was predominant. Conclusion: surgical treatment in thoraco-lumbar region fractures had satisfactory results in our milieu.

    Full Text Available OBJECTIVE: To present results obtained with laparoscopic correction of incisional lumbar hernia in patients with minimum follow-up of 1 year. MATERIALS AND METHODS: We prospectively studied 7 patients diagnosed with incisional lumbar hernia after physical examination and computerized tomography. We used laparoscopic transperitoneal access through 3 ports. One polypropylene mesh was introduced in the abdominal cavity and fixed by titanium clamps to the margins of the hernia ring following release of the peritoneum. RESULTS: All cases were successfully completed with no conversion required. Mean surgical time was 120 minutes and discharge from hospital occurred between the 1st and the 2nd postoperative days. There were no intraoperative complications or hernia recurrence in any case. Postoperatively, we had 2 minor complications: one case of seroma that resolved spontaneously after 60 days and one patient presenting lumbar pain that persisted until the 3rd postoperative month. The return to usual activities occurred on average 3 weeks following intervention. Of the 7 patients, 6 were satisfied with the esthetical and functional effect produced by the procedure. CONCLUSIONS: The surgical correction of incisional lumbar hernia by laparoscopic access is an excellent option for a minimally invasive treatment, with adequate long-term results.

    2009-07-01

    Full Text Available Abstract Background Most lumbar artificial discs are still composed of stainless steel alloys, which prevents adequate postoperative diagnostic imaging of the operated region when using magnetic resonance imaging (MRI. Thus patients with postoperative radicular symptoms or claudication after stainless steel implants often require alternative diagnostic procedures. Methods Possible complications of lumbar total disc replacement (TDR are reviewed from the available literature and imaging recommendations given with regard to implant type. Two illustrative cases are presented in figures. Results Access-related complications, infections, implant wear, loosening or fracture, polyethylene inlay dislodgement, facet joint hypertrophy, central stenosis, and ankylosis of the operated segment can be visualised both in titanium and stainless steel implants, but require different imaging modalities due to magnetic artifacts in MRI. Conclusion Alternative radiographic procedures should be considered when evaluating patients following TDR. Postoperative complications following lumbar TDR including spinal stenosis causing radiculopathy and implant loosening can be visualised by myelography and radionucleotide techniques as an adjunct to plain film radiographs. Even in the presence of massive stainless steel TDR implants lumbar radicular stenosis and implant loosening can be visualised if myelography and radionuclide techniques are applied.

    2015-12-01

    Iatrogenic neurologic deficits after lumbar spine surgery are rare complications, but important to recognize and manage. Complications such as radiculopathy, spinal cord compression, motor deficits (i.e. foot drop with L5 radiculopathy), and new onset radiculitis, while uncommon do occur. Attempts at mitigating these complications with the use of neuromonitoring have been successful. Guidance in the literature as to the true rate of iatrogenic neurologic deficit is limited to several case studies and retrospective designed studies describing the management, prevention and treatment of these deficits. The authors review the lumbar spinal surgery literature to examine the incidence of iatrogenic neurologic deficit in the lumbar spinal surgery literature. An advanced MEDLINE search conducted on May 14th, 2015 from January 1, 2004 through May 14, 2015, using the following MeSH search terms "postoperative complications," then subterms "lumbar vertebrae," treatment outcome," "spinal fusion," and "radiculopathy" were included together with "postoperative complications" in a single search. Postoperative complications including radiculopathy, weakness, and spinal cord compression were included. The definition of iatrogenic neurologic complication was limited to post-operative radiculopathy, motor weakness or new onset pain/radiculitis. An advanced MEDLINE search conducted on May 14th, 2015 using all of the above terms together yielded 21 results. After careful evaluation, 11 manuscripts were excluded and 10 were carefully reviewed. The most common indications for surgery were degenerative spondylolisthesis, spondylosis, scoliosis, and lumbar stenosis. In 2783 patients in 12 total studies, there were 56 patients who had reported a postoperative neurologic deficit for a rate of 5.7. The rates of deficits ranged from 0.46% to 17% in the studies used. The average rate of reported neurologic complications within these papers was 9% (range 0.46-24%). Thirty patients of a total of

  7. Lumbar disc arthroplasty: indications, biomechanics, types, and radiological criteria

    International Nuclear Information System (INIS)

    Lumbar total disc replacement (TDR) was developed to treat a painful degenerative lumbar motion segment while avoiding the disadvantages of fusion surgery, such as adjacent segment instabilities. Early clinical results with TDR have shown a significant reduction in low back pain and a significant improvement in disability scores. When compared to fusion, the results with TDR tend to be superior in the short-term follow-up and initial rehabilitation is faster. The radiological assessment is an integral part of the preoperative work-up. Plain X-rays of the lumbar spine should be complemented by flexion - extension views in order to assess residual segmental mobility. Computed tomography is used to exclude osteoarthritis of the zygapophyseal joints, Baastrup's disease (kissing spines) and other sources of low back pain. Magnetic resonance imaging is useful to exclude substantial disc protrusions; it allows for the detection of disc dehydration and bone marrow edema in the case of activated spondylochondrosis. If osteoporosis is suspected, an osteodensitometry of the lumbar spine should be performed. Postoperative plain X-rays should include antero-posterior and lateral views as well as flexion - extension views in the later postoperative course. Measurements should determine the disc space height in the lateral view, the segmental and total lumbar lordosis as well as the segmental mobility in the flexion - extension views. The ideal position of a TDR is exactly central in the ap-view and close to the dorsal border of the vertebral endplates in the lateral view. Malpositioning may cause segmental hyperlordosis and unbalanced loading of the endplates with the risk of implant subsidence and migration. (orig.)

  8. The Lumbar Lordosis in Males and Females, Revisited.

    Ori Hay

    Full Text Available Whether differences exist in male and female lumbar lordosis has been debated by researchers who are divided as to the nature of variations in the spinal curve, their origin, reasoning, and implications from a morphological, functional and evolutionary perspective. Evaluation of the spinal curvature is constructive in understanding the evolution of the spine, as well as its pathology, planning of surgical procedures, monitoring its progression and treatment of spinal deformities. The aim of the current study was to revisit the nature of lumbar curve in males and females.Our new automated method uses CT imaging of the spine to measure lumbar curvature in males and females. The curves extracted from 158 individuals were based on the spinal canal, thus avoiding traditional pitfalls of using bone features for curve estimation. The model analysis was carried out on the entire curve, whereby both local and global descriptors were examined in a single framework. Six parameters were calculated: segment length, curve length, curvedness, lordosis peak location, lordosis cranial peak height, and lordosis caudal peak height.Compared to males, the female spine manifested a statistically significant greater curvature, a caudally located lordotic peak, and greater cranial peak height. As caudal peak height is similar for males and females, the illusion of deeper lordosis among females is due partially to the fact that the upper part of the female lumbar curve is positioned more dorsally (more backwardly inclined.Males and females manifest different lumbar curve shape, yet similar amount of inward curving (lordosis. The morphological characteristics of the female spine were probably developed to reduce stress on the vertebral elements during pregnancy and nursing.

    Full Text Available We conducted a clinical and electromyographical study in patients with Chagas' disease in the indeterminate or chronic stages of the illness. Altogether 841 patients were examined. Only 511 were admitted within the protocol; the remainder patients were rejected because they showed other causes able to damage the nervous system. Fifty two (10.17% out of the 511 patients showed signs and symptoms of peripheral nervous system involvement in the form of sensory impairment and diminished tendon jerks suggesting the presence of neuropathy. Forty five of them were submitted to a conventional electromyographical examination. Fifteen of mem showed normal results, while the remainder 30 disclosed a reduced interference pattern, being most of the remaining motor unit potentials fragmented or poliphasic, reduced sensory and motor conduction velocities and diminished amplitude of the sensory action potential. The findings suggest that some chagasic patients in the indeterminate or chronic stages of the disease may develop a clinical mild sensory-motor peripheral neuropathy.El estúdio presente fue diseftado con ei objeto de pesquizar Ia existência de manifestaciones clinicas en pacientes afectados por enfermedad de Chagas, en estádio indeterminado o crônico, que tuviesen, ai menos, 2 reacciones serologicas positivas.

    "Lumbar three-point needling", meaning puncturing Shenshu (BL 23), Dachangshu (BL 25) and Ciliao(BL 32) at the same time, is a commonly used acupuncture method in the treatment of lumbocrural diseases. Points supplemented according to symptoms. Weizhong(BL 40) is supplemented for lumbar vertebra hypertrophy spondylitis; Weizhong (BL 40) and Kunlun(BL 60) supplemented for acute lumbar muscle sprain; Zhibian (BL 54), Huantiao (GB 30) and Ahshi points supplemented for nervi cluniam superior inflammation, and Sanyinjiao (SP 6) and Mingmen(GV 4) supplemented for impotence. Gauge-28 2 curt long needles are used. The needles are inserted perpendicularly into Shenshu(BL 23), Dachengshu(BL 25) and Ciliao(BL 32) to a depth of about 1.2 --- 1.5 cun. Other supplementary points are needled and stimulated with routine manipulations, generally the reducing method is used for excess syndrome, and the reinforcing method applied to deficiency syndrome. The author, on the basis of many years of clinical practice, considers that "lumbar three-point needling" is fairly effective in treating lumbosacral diseases.

    International Nuclear Information System (INIS)

    Objective: To compare outcomes after imaging-guided transforaminal lumbar nerve root blocks in MRI confirmed symptomatic disc herniation patients with and without Modic changes (MC). Methods: Consecutive adult patients with MRI confirmed symptomatic lumbar disc herniations and an imaging-guided lumbar nerve root block injection who returned an outcomes questionnaire are included. Numerical rating scale (NRS) pain data was collected prior to injection and 20–30 min after injection. NRS and overall improvement were assessed using the patient's global impression of change (PGIC) scale at 1 day, 1 week and 1 month post injection. The proportion of patients with and without MC on MRI as well as Modic I and Modic II was calculated. These groups were compared for clinically relevant ‘improvement’ using the Chi-squared test. Baseline and follow-up NRS scores were compared for the groups using the unpaired t-test. Results: 346 patients are included with MC present in 57%. A higher percentage of patients without MC reported ‘improvement’ and a higher percentage of patients with MC reported ‘worsening’ but this did not reach statistical significance. The numerical scores on the PGIC and NRS scales showed that patients with MC had significantly higher pain and worse overall improvement scores at 1 month (p = 0.048 and p = 0.03) and a significantly lower 1 month NRS change score (p = 0.04). Conclusions: Patients with MRI confirmed symptomatic lumbar disc herniations and MC report significantly lower levels of pain reduction after a lumbar nerve root block compared to patients without MC

    Full Text Available Abstract Background The to date evidence for a dose-response relationship between physical workload and the development of lumbar disc diseases is limited. We therefore investigated the possible etiologic relevance of cumulative occupational lumbar load to lumbar disc diseases in a multi-center case-control study. Methods In four study regions in Germany (Frankfurt/Main, Freiburg, Halle/Saale, Regensburg, patients seeking medical care for pain associated with clinically and radiologically verified lumbar disc herniation (286 males, 278 females or symptomatic lumbar disc narrowing (145 males, 206 females were prospectively recruited. Population control subjects (453 males and 448 females were drawn from the regional population registers. Cases and control subjects were between 25 and 70 years of age. In a structured personal interview, a complete occupational history was elicited to identify subjects with certain minimum workloads. On the basis of job task-specific supplementary surveys performed by technical experts, the situational lumbar load represented by the compressive force at the lumbosacral disc was determined via biomechanical model calculations for any working situation with object handling and load-intensive postures during the total working life. For this analysis, all manual handling of objects of about 5 kilograms or more and postures with trunk inclination of 20 degrees or more are included in the calculation of cumulative lumbar load.

    Full Text Available Introducción: El vendaje neuromuscular es una técnica que produce una estimulación muy selectiva sobre la piel a través de la aplicación de unas vendas elásticas especiales con el fin de lograr cambios propioceptivos, aumento o inhibición del tono muscular y mitigación de algias, entre otros. Objetivos: Comprobar si la aplicación del vendaje neuromuscular permite aumentar la flexión del raquis lumbar comparándola con otras técnicas de vendaje placebo (esparadrapo rígido convencional; Omniplaste®-E; observar la concordancia entre la prueba sit-and-reach y el test de Schober en la valoración de la ganancia de flexión lumbar. Material y métodos: Estudio piloto experimental a triple ciego. Se distribuyeron aleatoriamente 45 sujetos sanos de 20-55 años en tres grupos: 1 esparadrapo convencional; 2 Omniplaste®-E; 3 vendaje neuromuscular. En todos los participantes se evaluó la flexión del raquis lumbar mediante la prueba sit-and-reach y el test de Schober antes y después de la intervención siguiendo el mismo protocolo. Resultados: Considerado un intervalo de confianza del 95% y grado de significación estadística p<0,05 en todos los casos, se obtuvo un incremento estadísticamente significativo de la flexión lumbar en todos los grupos según la prueba sit-and-reach, que fue mayor en el grupo del vendaje neuromuscular (1,5 cm de mediana; p=0,011. Según el test de Schober, solamente el vendaje neuromuscular se mostró eficiente (p<0,001, incrementándose el valor basal en un 6,25% (1 cm de mediana. Conclusiones: La aplicación del vendaje neuromuscular sobre la columna lumbar mejora la flexión lumbar respecto a técnicas placebo a partir de los resultados obtenidos mediante el test de Schober, así como una mayor flexión global del tronco que estas técnicas según la prueba sit-and-reach. El test de Schober parece ser más fiable y preciso que la prueba sit-and-reach para estudios de este tipo.

    Full Text Available Background: Surgical treatment of adult lumbar spinal disorders is associated with a substantial risk of intraoperative and perioperative complications. There is no clearly defined medical literature on complication in lumbar spine surgery. Purpose of the study is to retrospectively evaluate intraoperative and perioperative complications who underwent various lumbar surgical procedures and to study the possible predisposing role of advanced age in increasing this rate. Materials and Methods: From 2007 to 2011 the number and type of complications were recorded and both univariate, (considering the patients′ age and a multivariate statistical analysis was conducted in order to establish a possible predisposing role. 133 were lumbar disc hernia treated with microdiscetomy, 88 were lumbar stenosis, treated in 36 cases with only decompression, 52 with decompression and instrumentation with a maximum of 2 levels. 26 patients showed a lumbar fracture treated with percutaneous or open screw fixation. 12 showed a scoliotic or kyphotic deformity treated with decompression, fusion and osteotomies with a maximum of 7.3 levels of fusion (range 5-14. 70 were spondylolisthesis treated with 1 or more level of fusion. In 34 cases a fusion till S1 was performed. Results: Of the 338 patients who underwent surgery, 55 showed one or more complications. Type of surgical treatment ( P = 0.004, open surgical approach (open P = 0.001 and operative time ( P = 0.001 increased the relative risk (RR of complication occurrence of 2.3, 3.8 and 5.1 respectively. Major complications are more often seen in complex surgical treatment for severe deformities, in revision surgery and in anterior approaches with an occurrence of 58.3%. Age greater than 65 years, despite an increased RR of perioperative complications (1.5, does not represent a predisposing risk factor to complications ( P = 0.006. Conclusion: Surgical decision-making and exclusion of patients is not justified only

  2. Critical analysis of extra peritoneal antero-lateral approach for lumbar plexus

    2011-08-01

    Full Text Available Lesions of lumbar plexus are uncommon and descriptions of surgical access are derived from vertebral spine approaches. METHOD: The extraperitoneal anterolateral approach to the lumbar plexus was performed in six adult fresh cadavers. The difficulties on dissection were related. RESULTS: An exposure of all distal elements of lumbar plexus was possible, but a cranial extension of the incision was needed to reach the iliohypogastric nerve in all cases. Ligation of vessels derived from common iliac artery was necessary for genitofemoral and obturator nerves exposure in two cases. The most proximal part of the lumbar roots could be identified only after dissection and clipping of most lumbar vessels. CONCLUSION: The extraperitoneal anterolateral approach allows appropriate exposure of terminal nerves of lumbar plexus laterallly to psoas major muscle. Cranial extension of the cutaneous incision may be necessary for exposure of iliohypogastric nerve. Roots exposure increases the risk of vascular damage.

  3. Review of early clinical results and complications associated with oblique lumbar interbody fusion (OLIF).

    2016-09-01

    Lumbar interbody fusion represents an effective surgical intervention for patients with lumbar degenerative diseases, spondylolisthesis, disc herniation, pseudoarthrosis and spinal deformities. Traditionally, conventional open anterior lumbar interbody fusion and posterior/transforaminal lumbar interbody fusion techniques have been employed with excellent results, but each with their own advantages and caveats. Most recently, the antero-oblique trajectory has been introduced, providing yet another corridor to access the lumbar spine. Termed the oblique lumbar interbody fusion, this approach accesses the spine between the anterior vessels and psoas muscles, avoiding both sets of structures to allow efficient clearance of the disc space and application of a large interbody device to afford distraction for foraminal decompression and endplate preparation for rapid and thorough fusion. This review aims to summarize the early clinical results and complications of this new technique and discusses potential future directions of research. PMID:27349468

    Lumbar stenosis is a well-defined pathologic condition with excellent surgical outcomes. Empiric evidence as well as randomized, prospective trials has demonstrated the superior efficacy of surgery compared to medical management for lumbar stenosis. Traditionally, lumbar stenosis is decompressed with open laminectomies. This involves removal of the spinous process, lamina, and the posterior musculoligamentous complex (posterior tension band). This approach provides excellent improvement in symptoms, but is also associated with potential postoperative spinal instability. This may result in subsequent need for spinal fusion. Advances in technology have enabled the application of minimally invasive spine surgery (MISS) as an acceptable alternative to open lumbar decompression. Recent studies have shown similar to improved perioperative outcomes when comparing MISS to open decompression for lumbar stenosis. A literature review of MISS for decompression of lumbar stenosis with tubular retractors was performed to evaluate the outcomes of this modern surgical technique. In addition, a discussion of the advantages and limitations of this technique is provided. PMID:22900163

    International Nuclear Information System (INIS)

    The purpose of this study was to compare changes in clinical symptoms and sequential findings of magnetic resonance imaging (MRI) in 66 patients managed with conservative treatment for lumbar disc herniation. In all but 12 patients, there was a good correlation between leg pain and MRI findings, although findings of MRI tended to slightly follow symptom improvement. A notable reduction of herniated mass was seen in a high frequency in sequentrated herniation from an extremely degenerated lumbar disk. The greater the degree of sequentration, the greater the reduction of herniated mass. A shorter duration of leg pain was significantly associated with greater reduction of the herniated mass; leg pain disappeared within 2 months when the herniated mass disappeared on MRI. Because herniated mass disappeared within a short period of time, the involvement of immune reaction was suggested, as well as the possibility of sequentration, degeneration, and phagocytosis.

    Full Text Available Burst fractures in acute spinal traumas are a difficult problem to solve. Different approaches and techniques have been utilized, but with high incidence of morbidity and mortality, besides unsatisfactory clinical and radiological results. Mini-open approaches recently emerged and have been shown to be safe and effective in the treatment of several spinal conditions. Here we report a case of acute lumbar burst fracture at L2 treated by minimally invasive true lateral approach posteriorly instrumented with percutaneous pedicle screws. The minimum disruptive access in addition to a rigid construction allowed a lumbar corpectomy without the morbidity of standard open approaches, lowering surgery costs and accelerating the patient recovery with successfully clinical and radiological results.

    Full Text Available Non-traumatic paraplegia caused by herniation of the cervical intervertebral disc is anuncommon postoperative complication. A patient with claudication and radiculopathy wasscheduled for lumbar laminectomy due to spinal stenosis. Postoperatively, numbness belowT6 was found in his both legs of the patient. MRI showed a protruded intervertebral discbetween C6 and C7. Despite urgent disectomy, the patient's lower extremities remained paralyzedwithout significant improvement for 3 months. Loss of muscle support during generalanesthesia, excessive neck extension during endotracheal intubation and positioning, as wellas bucking and agitation are believed as triggering factors for the protrusion of the cervicaldisc. We suggest that a complete history taking and physical examination be accomplishedin patients scheduled for lumbar spine surgery in order to exclude coexisting cervical spinedisorders. In addition, skillful endotracheal intubation and careful neck positioning aremandatory for patients receiving surgery in the prone position.

    Degenerative lumbar spine diseases, i.e., sacrolumbar stenosis, intervertebral disk degeneration and protrusion and spondylosis deformans of the canine lumbar spine were studied in eleven canine patients and three healthy controls using radiography and 0.02 T and 0.04 T low field magnetic resonance imaging. The T1 and T2 weighted images were obtained in sagittal and transverse planes. The loss of hydration of nucleus pulposus, taken as a sign of degeneration in the intervertebral disks, could be evaluated in both T1 and T2 weighted images. As a noninvasive method magnetic resonance imaging gave more exact information about the condition of intervertebral disks than did radiography. Sacrolumbar stenosis and compression of the spinal cord or cauda equina and surrounding tissue could be evaluated without contrast medium

  15. Lumbar posterior marginal intra-osseous cartilaginous node

    This report concerns 12 patients, eight young adults and four adolescents, presenting with lumbar or sciatic pain. This was associated with an unusual defect of the inferior and posterior edges of the vertebral bodies of L4 or L5, together with a small bony ridge protruding into the spinal canal. We found 11 similar cases in the literature, all involving adolescents except for one young adult. It has been considered to be the result of a fracture of the posterior ring apophysis in association with a herniated disc. In our cases, in the absence of any known previous trauma, the radiological features and surgical results and the similarity and frequent association with typical lesions of Scheuermann disease, all suggest a posterior marginal cartilaginous node. The inferior lumbar location and frequent association with herniated disc and sciatic nerve root compression in young patients are discussed.

  16. Magnetic resonance imaging of lumbar vertebral apophyseal ring fractures

    International Nuclear Information System (INIS)

    Posterior lumbar vertebral apophyseal ring fractures are described in three adolescents presenting with severe low back pain, spinal tenderness and lower limb neurological deficit. Magnetic resonance imaging showed severe L4/5 posterior disc protrusion in all three patients. The actual fracture fragment was visualized with difficulty on MRI alone. The diagnosis of apophyseal ring fracture was made by either radiography or CT. Computed tomography delineated the size, shape and site of the fracture fragment. Surgical confirmation was obtained in all cases. Posterior lumbar vertebral apophyseal ring fractures may be difficult to visualize on MR imaging. Careful review of radiographs, supplemented by targeted CT, is necessary for the correct diagnosis and management of this entity. Copyright (1998) Blackwell Science Pty Ltd

    The decision about operative or non-operative treatment of herniated lumbar discs has to be based on the results of clinical and neurological examination. Results of imaging techniques as CT or MRI are secondary. Various percutaneous endoscopic or open techniques have been described. The most appropriate technique is determined by the anatomical situation of the dislocated lumbar disc tissue. Intradiscal percutaneous therapies such as percutaneous nucleotomy and laser decompression are possible, but they revealed poor results in prospective randomized and controlled studies. Chemonucleolysis remains as an effective intradiscal technique at the time, but is afflicted with side effects and complications. Endoscopic transforaminal or interlaminary techniques are still experimental. Whenever open surgery is necessary, microsurgical techniques are preferred. If a certain technique is to be applied, there has to be the correct indication, technical support for and experience in using the choosen method. PMID:10474839

    The authors report their experiences based on 41 cases operated on for lumbar spinal stenosis between 1981 and 1988. The series included 28 men and 13 women aged between 23 and 63 years (mean age: 48 years). Neurogenic intermittent claudication was the presenting symptom in only 12% of the cases, as opposed to lumbago-sciatica in 78%. Clinical examination did not provide any specific elements. The key to diagnosis was lumbar myelography. Laminectomy was the most important aspect of treatment which, in certain cases, was associated with vertebral stabilization by arthrodesis (3 cases). There were ten minor operative complications. Further surgery was necessary in five cases (12%). Therapeutic results in patients followed from one to eight years (35 cases) were satisfactory. The discussion covers nosologic, clinicoradiologic and therapeutic aspects. PMID:2142258

  1. The treatment of lumbar disc herniation: a comparison between percutaneous lumbar diskectomy combined with ozone and percutaneous lumbar diskectomy combined with collagenase

    International Nuclear Information System (INIS)

    Objective: To evaluate the short-term curative effect and the incidence of postoperative adverse events of percutaneous lumbar diskectomy (PLD) combined with ozone or PLD combined with collagenase in treating lumbar disk herniation. Methods: A total of 223 patients with lumbar disk herniation were enrolled in this study. Patients in the study group (n=108) were treated with PLD combined with ozone, while patients in the control group (n=115) were treated with PLD combined with collagenase. The short-term effectiveness and the incidence of postoperative adverse events were documented. The results were analyzed and compared between the two groups. Results: In the study group, the excellent and good therapeutic results were achieved in 85.18% of the patients (n=92) and the occurrence of adverse events was 5.56%, while in the control group, the excellent and good therapeutic results were achieved in 80.00% of the patients (n=92) and the occurrence of adverse events was 13.04%. No significant difference in the short-term effectiveness existed between the two groups (Pearson Chi-Square =1.038, P=0.308). And the difference in the occurrence of postoperative adverse events was not significant between the two groups (Pearson Chi-Square =3.661, P=0.056). No disc infection occurred in the study group. Conclusion: The short-term curative effect of PLD combined with ozone is not significantly different from that of PLD combined with collagenase. In order to maintain decompression within the disc for a long period and to reduce the incidence of postoperative adverse events PLD combined with ozone ablation is an effective complementary treatment.

  2. Lumbar gibbus in storage diseases and bone dysplasias

    International Nuclear Information System (INIS)

    Objective. The objective of this study was to review the problem of lumbar gibbus in children with storage diseases and bone dysplasias utilizing plain films and MR imaging. Materials and methods. Clinical histories and radiographic images in five patients with storage diseases [four mucopolysaccharidosis (MPS) and one mucolipidosis[ and two with achondroplasia were reviewed. The International Skeletal Dysplasia Registry (Los Angeles, Calif.), surveyed for all patients with lumbar gibbus and skeletal dysplasias, provided 12 additional cases. Results. All patients had localized gibbus of the upper lumbar spine, characterized by anterior wedging and posterior displacement of the vertebrae at the apex of the curve, producing a beaked appearance. The curve, exaggerated in the sitting or standing position, was most severe in the two patients with MPS-IV (one of whom died). Both developed severe neurologic signs and symptoms requiring surgical intervention. In four patients, MR images demonstrated the apex of the curve to be at or below the conus. Two patients demonstrated anterior herniation of the intervertebral discs at the apex of the curve, though the signal intensity of the intervertebral discs was normal. Conclusion. Lumbar gibbus has important neurologic and orthopedic implications, and is most severe in patients with MPS. The etiology of the gibbus with vertebral beaking is multifactorial and includes poor truncal muscle tone, weight-bearing forces, growth disturbance and anterior disc herniation. The curve is generally at or below the conus. Neurologic complications are unusual, although orthopedic problems can arise. Due to their longer survival, patients with achondroplasia or Morquio's disease are more vulnerable to eventual gibbus-related musculoskeletal complications. (orig.). With 6 figs., 2 tabs

    Lumbar discal cyst is a rare cause of radiculopathy. Their exact pathogenesis and the optimal treatment modality remain unidentified. Depending on their location, discal cysts cannot always be easily identified intraoperatively. We describe 2 patients with discal cysts and introduce an intraoperative discography technique for discal cyst location. Both patients were treated with surgical excision; with intraoperative discography, the cystic lesions could easily be detected and removed.

    Among the patients operated because of lumbar disc herniation from January 1973 to May 1979 at Korea University Hospital, 154 cases were analyzed radiologically and the following conclusions were obtained. 1. The ratio of male to female was 1.96 : 1. 2. The incidences of single and multiple involvement were 74.7% and 25.3%. 3. Most frequent level of lumbar disc herniation was L4-5 interspace. 4. The incidences of left, central and bilateral defects were 45.45%, 33.76%, 12.33% and 8.44% respectively. 5. The incidences of spina bifida and transitional vertebra were 24.04% and 9.09% respectively. 6. The overall mean of the lumbosacral angle was 33.97 .deg. 7. The overall mean depth of the lumbar lordosis was 8.48 mm. 8. The ratio of the height of L4-5 interspace to the shorter anteroposterior diameter of L-5 body was obtained by authors' idea. The mean ratios of male and female patients of L4-5 disc herniation which had no evidence of the narrowing of L4-5 interspace on simple radiologic finding were 0.3042 and 0.3064 respectively. So the ratio had a little value in the diagnosis of L4-5 disc herniation on simple radiologic study. 9. Myelography had high diagnostic accuracy, and the majority of the pseudonegative finding on lumbar disc herniation myelographically was seen at L4-5 disc herniation.

    2005-01-01

    Full Text Available Background: Avulsion or fracture of posterior ring apophysis of lumbar vertebra is not a common clinical entity and is missed often. These fractures are mostly traumatic lesions typically seen in adolescents and young adults, because fusion in this area is not complete until the age of 18 to 25 years. These fractures are occult on plain radiographs and are frequently missed due to unfamiliarity with the entity. But, CT scanning and MR imaging shows characteristic picture. Methods: We had 21 cases of fracture of posterior margin of a lumbar vertebral body from 1991 to 2002. Fracture in all patients were classified according to CT imaging, into the three types described by Takata et al. Out of these, 8 patients were of type I, 4 patients of type II and 9 patients of type III respectively. Focal deficit / muscle weakness was present in only three patients. No fractures of type IV (Epstein et al was found. Twelve patients were treated conservatively and 9 patients were treated by posterior decompression with total laminectomy and removal of retropulsed fragment and discectomy. Results: The mean follow-up period was of 42 months. Conventional radiography could locate the fracture in only 6 cases and CT scan was required in all cases for stamping the diagnosis and classification. Though it is uncommon, high index of suspicion is required to diagnose it, in especially adolescent patients. All the 21 patients had good outcome following the management. Conclusion: Avulsion or fracture of posterior margin of lumbar vertebral body is not so rare entity. In children and young adults diagnosed as having lumbar disc herniation, this lesion may be the proper diagnosis. These fractures need to be accurately diagnosed because as compared to simple disc herniations these fractures require more extensive exposure and resection to relieve the nerve impingent.

    International Nuclear Information System (INIS)

    To determine the sensitivity of CT scan in diagnosing lumbar disc prolapse. Study Design: Validation Study. Place and Duration of Study: Combined Military Hospital Multan. From August 2009 to July 2010. Patients and Methods: Patients with clinical suspicion of lumbar disc prolapsed were referred from Neurosurgical OPD for CT scan of lumbar spine. The target CT finding was disc prolapse with compression of dural sac or narrowing of lateral recess / neuroforamina. Patients were divided into positive and negative cases on basis of detective of target finding by CT. All positive cased underwent surgery. Negative cases were first treated conservatively and only patients with persistent symptoms underwent surgery. The findings of CT as index test were compared with operative findings as gold reference standard. Results: Total 61 cases were included in study, 51 positive cases and 10 negative cases. Mean age of patients was 44.6 years. There were 42 males and 19 females. Positive cases after surgery showed 48 true positive and 3 false positive cases. Two negative cases showed persistent symptoms, underwent surgery and found positive for target finding (false negatives. Eight negative cases became symptom free after conservative treatment. These CT negative cases turning asymptomatic were ethically not feasible for surgery so assumed as true negative. The above data of 61 cases was computed in 2x2 table to calculate sensitivity (96%) and positive predictive value (94%) of CT scan in diagnosing lumbar disc prolapse. Conclusion: CT scan is having highly sensitivity and positive predictive value in detecting lumber disc prolapsed. It is reliable imaging modality in this regard. (author)

    The diffusion of small solutes into the intervertebral discs of cadaveric lumbar motion segments was measured using a radioactive tracer technique. The motion segments were wedged and loaded to simulate erect posture and flexed sitting postures. The results show that erect posture favours diffusion into the anterior half of the disc compared to the posterior half. Flexed posture, by deforming the annulus fibrosus, reverses this imbalance.

    Lumbar spondylolysis and spondylolisthesis are common spinal disorders that most of the times are incidental findings or respond favorably to conservative treatment. In a small percentage of the patients, surgical intervention becomes necessary. Because too much attention has been paid to novel surgical techniques and new modern spinal implants, some of fundamental concepts have been forgotten. Identifying that small but important number of patients with lumbar spondylolysis or spondylolisthesis who would really benefit from lumbar surgery is one of those forgotten concepts. In this paper, we have developed an algorithmic approach to determine who is a good candidate for surgery due to lumbar spondylolysis or spondylolisthesis. PMID:25558333

  5. Value of the lumbar lordotic angle taken from CT scanogram as an index of back pain

    International Nuclear Information System (INIS)

    'Normal' spinal posture is generally accepted as moderate lordosis of the cervical and the lumbar sections of spine and moderate kyphosis of the thoracic and sacrococcygeal sections. Among these normal range of the lumbar lordosis is less well defined. CT is very useful method to identified the bony structure and adjacent soft tissue of the spine, so it is very available method to detect accurate lumbar lordotic angle by using lateral Scanogram. Analysis and comparison of lumbar lordotic angles, crossing angle are drawn each parallel line to the superior end plate of body of 1st. lumbar vertebra and to the inferior end plate of the 5th. lumbar vertebra, in 174 cases with backache and 50 cases normal groups at Kangnam General Hospital Public Corporation, from Aug. 1985 to Jul 1986. Male and female were almostly same affected in backache group (1.1:1). And most lumbar lordotic angles were 10 to 40 between all backache age group. On backache group, over all mean lumbar lordotic angles were 24.7±8.9 but no significant difference at mean value of the each diseases, such as HIVD, Degenerative Spondylosis or No Remarkable Findings group. On control group, over all mean ones were 29.2±8.0. So, significant difference of lumbar lordotic angle between backache and control group, and most difference is at 5th. decade group (p 0.01).

CT is very useful method to identified the bony structure and adjacent soft tissue of the spine, so it is very available method to detect accurate lumbar lordotic angle by using lateral Scanogram. Analysis and comparison of lumbar lordotic angles, crossing angle are drawn each parallel line to the superior end plate of body of 1st. lumbar vertebra and to the inferior end plate of the 5th. lumbar vertebra, in 174 cases with backache and 50 cases normal groups at Kangnam General Hospital Public Corporation, from Aug. 1985 to Jul 1986. Male and female were almostly same affected in backache group (1.1:1). And most lumbar lordotic angles were 10 to 40 between all backache age group. On backache group, over all mean lumbar lordotic angles were 24.7+-8.9 but no significant difference at mean value of the each diseases, such as HIVD, Degenerative Spondylosis or No Remarkable Findings group. On control group, over all mean ones were 29.2+-8.0. So, significant difference of lumbar lordotic angle between backache and control group, and most difference is at 5th. decade group (p 0.01).

  7. Lumbar CT findings of patients with low back pain

    International Nuclear Information System (INIS)

    Low back pain is probably the second most common disease entity to upper respiratory infection in developed country. We were missing at least 50% of the pathologic conditions by using conventional diagnostic modalities in low back pain. They did tell us nothing or little about facet abnormalities, lateral recesses, vertebral canal and soft tissue surrounding lumbar spines. High resolutional CT has been the biggest turning point in the diagnosis and management of low back pain. CT make a contribution to reducing the morbidity and probably the cost of evaluating patients with low back pain, and to increasing diagnostic accuracy. We observed 100 cases of lumbar CT using TCT 80A scanner for the evaluation of low back pain during the period from Apr. 1985 to Sept. 1985 at Chung-Ang University Hospital. Lumbar CT scan reveals high-positive findings (98%) in low back pain patients. Common low back disorders in CT are disc bulging (53%), herniated nucleus pulposus (32%), degenerative arthritis in posterior facet joints (27%), spinal stenosis (20%) and postoperative spines (15%). Uncommon low back disorders in CT are compression fracture of vertebral bodies, spondylolysis or spondylolisthesis, tropism, transitional vertebra, Scheueman's disease, limbic fracture, transverse process or articular process fracture, sacroiliac joint subluxation, conjoined nerve root and meningocele.

    Full Text Available For the evaluation of the Lumbar pedicle morphometry and its relation to the neural structures, 14 male adult cadavers were dissected, and the size of the lumbar pedicle was assessed by measuring its sagittal and transversal diameter. It was found that the size of the pedicle increases from L2 to L5, both in the sagittal and transversal diameter, the first bigger. The relation of the lumbar pedicle to the neural structures was evaluated by measuring the distance between dura-mater and the pedicle medial area, the distance between the most distal area of the pedicle and the nerve root that appears under it, and , to obtain in an indirect way, the distance between the pedicle apex and the nerve root that appears over it. The acquired results showed that the distance between the most distal area of the pedicle and the nerve root that appears under it, and the distance between the pedicle medial area and dura-mater, do not increase from L2 to L5, and they are in average 1,98 and 3,02 respectively. The distance between the pedicle apex and the nerve root that appears over it, increases from L2 to L5, varying from 13,64 in L2 to 21,62 in L5. The location of the spinal ganglion in relation to the pedicle has also been found, and 87% of the spinal ganglions are located in the foraminal zone.

  9. Assessment of lumbar spinal canal stenosis by magnetic resonance phlebography

    International Nuclear Information System (INIS)

    There is evidence to suggest that cauda equina intermittent claudication is caused by local circulatory disturbances in the cauda equina as well as compression of the cauda equina. We evaluated the role of magnetic resonance phlebography (MRP) in identifying circulatory disturbances of the vertebral venous system in patients with lumbar spinal canal stenosis. Extensive filling defects of the anterior internal vertebral venous plexus were evident in patients with lumbar spinal canal stenosis (n=53), whereas only milder abnormalities were noted in patients with other lumber diseases (n=16) and none in normal subjects (n=13). The extent of the defect on MRP correlated with the time at which intermittent claudication appeared. In patients with lumber spinal canal stenosis, extensive defects of the internal vertebral venous plexus on MRP were noted in the neutral spine position, but the defect diminished with anterior flexion of the spine. This phenomenon correlated closely with the time at which intermittent claudication appeared. Our results highlight the importance of MRP for assessing the underlying mechanism of cauda equina intermittent claudication in patients with lumbar spinal canal stenosis and suggest that congestive venous ischemia is involved in the development of intermittent claudication in these patients.

    Full Text Available Posterior lumbar interbody fusion using cages, titanium rods, and pedicle screws is considered today as the gold standard of surgical treatment of lumbar degenerative disease and has produced satisfying long-term fusion rates. However this rigid material could change the physiological distribution of load at the instrumental and adjacent segments, a main cause of implant failure and adjacent segment disease, responsible for a high rate of further surgery in the following years. More recently, semirigid instrumentation systems using rods made of polyetheretherketone (PEEK have been introduced. This clinical study of 21 patients focuses on the clinical and radiological outcomes of patients with lumbar degenerative disease treated with Initial VEOS PEEK®-Optima system (Innov’Spine, France composed of rods made from PEEK-OPTIMA® polymer (Invibio Biomaterial Solutions, UK without arthrodesis. With an average follow-up of 2 years and half, the chances of reoperation were significantly reduced (4.8%, quality of life was improved (ODI = 16%, and the adjacent disc was preserved in more than 70% of cases. Based on these results, combined with the biomechanical and clinical data already published, PEEK rods systems can be considered as a safe and effective alternative solution to rigid ones.

    To evaluate the relevant clinical and radiographical findings for the diagnosis of an arteriovenous fistula after a lumbar discectomy. Five patients with an arteriovenous fistula following a lumbar discectomy were preoperatively diagnosed and treated. We retrospectively evaluated the level of surgery, injured vessels, clinical symptoms, physical findings, and the interval between surgery and treatment. Effective and fast diagnostic methods for determining the presence of a postoperative arteriovenous fistula were evaluated. All of the arteriovenous fistulas resulted from operative injuries of the iliac arteries and veins. They were diagnosed after a mean time of 22 months (range 2 months-4 years) in spite of various symptoms and signs shortly after surgery. The arteriovenous fistulas were confirmed with angiography and were treated by surgery for 3 patients and by insertion of a stent-graft in 2 patients. Postoperative CT angiography showed the complete occlusion of the fistula tract and the normal blood flow. Essential clinical information and radiological examination, especially CT angiography with 3D reconstruction, in necessary to obtain to diagnose an arteriovenous fistula after a lumbar discectomy.

    To understand the usefulness of the lumbar MRI studies to establish therapeutic plans for cauda equina syndrome (CES) including the management of rectal and bladder dysfunction symptoms. We retrospectively reviewed the lumbar MRI studies of 10 patients with CES. Their diagnoses included four adhesive arachnoiditis of cauda equina (CE), three conus medullaris atrophies, three spinal canal stenoses, one tuberculous leptomeningitis, one metastatic tumor on the sacral canal, and one dural arteriovenous fistula with venous congestion of the conus medullaris. In 6 of the 10 total cases the symptoms of rectal and bladder dysfunction were resolved by decompression laminectomies (n=2), irradiation (n=1), glue embolization (n=1), anticholine and steroid infusion (n=1), and anti-tuberculous medication (n=1) within at least 5 days. The 4 other cases were settled by lumboperitoneal shunting and neural stem cell implants. The study results indicate that lumbar MRI is the modality of choice in search for the causative lesion and to subsequently set up the best therapeutic plans for patients with CES.

    Full Text Available OBJECTIVE: To evaluate interobserver agreement of Glassman classification for posterolateral lumbar spine arthrodesis.METHODS: One hundred and thirty-four CT scans from patients who underwent posterolateral arthrodesis of the lumbar and lumbosacral spine were evaluated by four observers, namely two orthopedic surgeons experienced in spine surgery and two in training in this area. Using the reconstructed tomographic images at oblique coronal plane, 299 operated levels were systematically analyzed looking for arthrodesis signals. The appearance of bone healing in each operated level was classified in five categories as proposed by Glassman to the posterolateral arthrodesis: 1 bilateral solid arthrodesis; 2 unilateral solid arthrodesis; 3 bilateral partial arthrodesis; 4 unilateral partial arthrodesis; 5 absence of arthrodesis. In a second step, the evaluation of each operated level was divided into two categories: fusion (including type 1, 2, 3, and 4 and non fusion (type 5. Statistical analysis was performed by calculating the Kappa coefficient considering the paired analysis between the two experienced observers and between the two observers in training.RESULTS: The interobserver reproducibility by the kappa coefficient for arthrodesis consolidation analysis for the classification proposed, divided into 5 types, was 0.729 for both experienced surgeons and training surgeons. Considering only two categories kappa coefficient was 0.745 between experienced surgeons and 0.795 between training surgeons. In all analyzes, we obtained high concordance power.CONCLUSION: Interobserver reproducibility was observed with high concordance in the classification proposed by Glassman for posterolateral arthrodesis of the lumbar and lumbosacral spine.

    The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seated position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110°, 146°, and 182°. In addition, the trunk extensor muscle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (Ppelvic stabilization may be more effective for MF and IL muscle activity compared to that without pelvic stabilization.

    Therapeutic armamentarium for symptomatic intervertebral disc herniation includes conservative therapy, epidural infiltrations (interlaminar or trans-foraminal), percutaneous therapeutic techniques and surgical options. Percutaneous, therapeutic techniques are imaging-guided, minimally invasive treatments for intervertebral disc herniation which can be performed as outpatient procedures. They can be classified in 4 main categories: mechanical, thermal, chemical decompression and biomaterials implantation. Strict sterility measures are a prerequisite and should include extensive local sterility and antibiotic prophylaxis. Indications include the presence of a symptomatic, small to medium sized contained intervertebral disc herniation non-responding to a 4–6 weeks course of conservative therapy. Contraindications include sequestration, infection, segmental instability (spondylolisthesis), uncorrected coagulopathy or a patient unwilling to provide informed consent. Decompression techniques are feasible and reproducible, efficient (75–94% success rate) and safe (>0.5% mean complications rate) therapies for the treatment of symptomatic intervertebral disc herniation. Percutaneous, imaging guided, intervertebral disc therapeutic techniques can be proposed either as an initial treatment or as an attractive alternative prior to surgery for the therapy of symptomatic herniation in both cervical and lumbar spine. This article will describe the mechanism of action for different therapeutic techniques applied to intervertebral discs of cervical and lumbar spine, summarize the data concerning safety and effectiveness of these treatments, and provide a rational approach for the therapy of symptomatic intervertebral disc herniation in cervical and lumbar spine.

    An 82-year-old woman who had received two operations for lumbar spinal stenosis was treated successfully for persistent nocturnal leg cramps with lumbar sympathetic ganglion block. The stent in the right popliteal artery improved cramps again following the recurrence one month after the block. The head up position in bed against gastroesophageal reflux was found injurious at the time of second recurrence one year after stenting. After the correction of lying position, her legs were in good condition for over one year. Cramps in this case might be caused by disturbances of blood flow supply for motor nerves of the legs by obstructive arterial sclerosis of the nerve injured from root compression. PMID:27188122

    Full Text Available The objectives of this research were to examine the efeects of feed containing soybean tofu and tempeh on lumbar bone density and mass of ovariectomized female rats. Twenty four 17 weeks-old Sprague-Dawley rats were randomly assigned to four group, i.e.: (1 non-ovariectomized rats fed casein based diet (NonOvx, (2 ovariectomized rats fed casein based diet (OvxC, (3 ovariectomized rats fed diet containing soybean tofu (OvxH, and (4 ovariectomized rats fed diet containing soybean tempeh (OvxT; in three block based on their body weight. The result show that body weight gram of ovariectomized rats was greater than nonovariectomized. Ovariectomy caused atrophy of the uterus, and resulted in higher serum calcium level. The lower lumbar vertebrae density of ovariectomized rats was observed and the decrease was prevented by tofu.

  1. Studies on the pathogenesis of degenerative lumbar canal stenosis by computed tomography, 2. Investigation about measurements of the lumbar canal

    Kido, Kenji

    1987-07-01

    To evaluate the significance of measurement parameters for the lumbar canal (LC), a retrospective analysis was made of computed tomography (CT) scans in a total of 129 patients, including 20 with degenerative lumbar canal stenosis (DLCS), 65 with degenerative spondylosis, 21 with disc hernia, and 23 with lumbar pain. The shape of the transverse LC was not reflected by the anteroposterior and transverse diameters of LC, but was somewhat reflected by the transverse area of LC. The transverse area of dural sac (DS) was considered important in determining the degree of stenosis. Regarding the transverse area, the DS correlated more strongly with the LC with soft-tissue windows than that with bone windows. The angle of intervertebral joint was likely to be related to the pathophysiology of the LC. In particular, sagittal tendency was seen at the levels of L3-4 and L4-5 in the DLCS group. There was correlation between the angle of intervertebral joint and the transverse areas of both soft-tissue LC and DS at the levels of L4-5. A multivariate analysis suggested the possibility that the significance of measurement parameters might vary depending on the vertebral level for the lower lumbar spine. The following criteria for indicating DLCS were obtained: 1) a transverse area of less than or equal to 100 mm/sup 2/ for DS or less than or equal to 118 mm/sup 2/ for soft-tissue LC at the levels of L3-4; 2) a transverse area of less than or equal to 90 mm/sup 2/ for DS and an angle of less than or equal to 90 deg for the intervertebral joint at the levels of L4-5; and 3) lateral recess of less than or equal to 3 mm in anteroposterior diameter at the levels of L5-S1.

    Full Text Available Background: Avaialable minimal invasive arthro/endoscopic techniques are not compatible with 30 degree arthroscope which orthopedic surgeons uses in knee and shoulder arthroscopy. Minimally invasive “Arthrospine assisted percutaneous technique for lumbar discectomy” is an attempt to allow standard familiar microsurgical discectomy and decompression to be performed using 30° arthroscope used in knee and shoulder arthroscopy with conventional micro discectomy instruments. Materials and Methods: 150 patients suffering from lumbar disc herniations were operated between January 2004 and December 2012 by indiginously designed Arthrospine system and were evaluated retrospectively. In lumbar discectomy group, there were 85 males and 65 females aged between 18 and 72 years (mean, 38.4 years. The delay between onset of symptoms to surgery was between 3 months to 7 years. Levels operated upon included L1-L2 (n = 3, L2-L3 (n = 2, L3-L4 (n = 8, L4-L5 (n = 90, and L5-S1 (n = 47. Ninety patients had radiculopathy on right side and 60 on left side. There were 22 central, 88 paracentral, 12 contained, 3 extraforaminal, and 25 sequestrated herniations. Standard protocol of preoperative blood tests, x-ray LS Spine and pre operative MRI and pre anaesthetic evaluation for anaesthesia was done in all cases. Technique comprised localization of symptomatic level followed by percutaneous dilatation and insertion of a newly devised arthrospine system devise over a dilator through a 15 mm skin and fascial incision. Arthro/endoscopic discectomy was then carried out by 30° arthroscope and conventional disc surgery instruments. Results: Based on modified Macnab's criteria, of 150 patients operated for lumbar discectomy, 136 (90% patients had excellent to good, 12 (8% had fair, and 2 patients (1.3% had poor results. The complications observed were discitis in 3 patients (2%, dural tear in 4 patients (2.6%, and nerve root injury in 2 patients (1.3%. About 90% patients

    Full Text Available ABSTRACT: The focal calcification or ossification of ligamentum flavum is a rare cau se of thoracic myelopathy and most often occurs among individuals of Japanese descent. It is rare in other ethnic groups and in individuals below the age of 50 year. It is most often described at the lower thoracic level, being uncommon in the lumbar regio n and rare in the cervical region. Here, we present the case of a 40 - year - old Indian female patient who sought medical attention with a six month history of paraesthesia of the lower limbs and progressive difficulty in walking. The clinical profile, togeth er with computed tomography and magnetic resonance imaging of the spine, led to a diagnosis of compressive lumbar myelopathy due to ossification of the ligamentum flavum of lumbar spine. The patient underwent laminectomy and dissection of some of the affec ted ligamentum flavum. After three months of clinical follow - up, the patient had progressed favorably , having no sensory complaints and again becoming ambulatory

    2016-07-01

    Previous work suggests females are evolutionarily adapted to have greater lumbar lordosis than males to aid in pregnancy load-bearing, but no consensus exists. To explore further sex-differences in the lumbar spine, and to understand contradictions in the literature, we conducted a cross-sectional retrospective study of sex-differences in lumbar spine morphology and sacral orientation. In addition, our sample includes data for separate standing and supine samples of males and females to examine potential sex-differences in postural loading on lumbosacral morphology. We measured sagittal lumbosacral morphology on 200 radiographs. Measurements include: lumbar angle (L1-S1), lumbar vertebral body and disc wedging angles, sacral slope and pelvic incidence. Lumbar angle, representative of lordotic curvature between L1 and S1, was 7.3° greater in females than males, when standing. There were no significant sex-differences in lumbar angle when supine. This difference in standing lumbar angle can be explained by greater lordotic wedging of the lumbar vertebrae (L1-L5) in females. Additionally, sacral slope was greater in females than males, when standing. There were no significant sex-differences in pelvic incidence. Our results support that females have greater lumbar lordosis than males when standing, but not when supine - suggesting a potentially greater range of motion in the female spine. Furthermore, sex-differences in the lumbar spine appear to be supported by postural differences in sacral-orientation and morphological differences in the vertebral body wedging. A better understanding of sex-differences in lumbosacral morphology may explain sex-differences in spinal conditions, as well as promote necessary sex-specific treatments. PMID:26916466

    The ovine lumbar intervertebral disc is a useful model for the human lumbar disc. We present preliminary estimates of diffusion coefficients and T2 relaxation times in a pilot MRI study of the ovine lumbar intervertebral disc during uniaxial compression in vitro, and identify factors that hamper the ability to accurately monitor the temporal evolution of the effective diffusion tensor at high spatial resolution.

  12. Hip and pelvis diseases on lumbar AP radiographs including both hip joints

    International Nuclear Information System (INIS)

    To determine the frequency of diseases of the hip and pelvis, as seen of plain radiography of the lumbar spine in patients with suspicious lumbar disease, and to evaluate the methods used of lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1252 patients, taken using 14' x 17' film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesions, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesions in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 of the 20 hospitals which responded, 14' x 17' film was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful was to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis

    OBJECTIVES This study aimed to determine the prevalence of diabetes mellitus in patients with spinal stenosis and lumbar vertebral disk degeneration, and the correlation of diabetes with these diseases. STUDY DESIGN This is a cross-sectional study. METHODS This case–control study was performed during 2012–2014 with 110 patients suffering from lumbar spinal stenosis and 110 patients with lumbar disk herniation, who were diagnosed using clinical and radiological evidences. Additionally, 110 participants who were referred to the clinic and did not show clinical signs of degenerative diseases of the lumbar spine entered the study as a control group. Demographic data and medical histories of the patients were collected using checklists. RESULTS A total of 50 patients (15.2%) were diagnosed with diabetes, which comprised 32 (29.1%) in the stenosis group, 7 (6.4%) in the lumbar disk herniation group, and 11 (10%) in the control group. The prevalence of diabetes in women with spinal stenosis and women with lumbar disk herniation was 35.9% and 10.3%, respectively, whereas prevalence of diabetes in women was 10.9% in the control group. This difference was statistically significant in the spinal stenosis group in comparison with the controls (P diabetes and lumbar spinal stenosis. Diabetes mellitus may be a predisposing factor for the development of lumbar spinal stenosis.

    A combined approach involving optimization and the finite element technique was used to predict biomechanical parameters in the lumbar spine during static lifting in the sagittal plane. Forces in muscle fascicles of the lumbar region were first predicted using an optimization-based force model including the entire lumbar spine. These muscle forces as well as the distributed upper body weight and the lifted load were then applied to a three-dimensional finite element model of the thoracolumbar spine and rib cage to predict deformation, the intradiskal pressure, strains, stresses, and load transfer paths in the spine. The predicted intradiskal pressures in the L3-4 disk at the most deviated from the in vivo measurements by 8.2 percent for the four lifting cases analyzed. The lumbosacral joint flexed, while the other lumbar joints extended for all of the four lifting cases studied (rotation of a joint is the relative rotation between its two vertebral bodies). High stresses were predicted in the posterolateral regions of the endplates and at the junctions of the pedicles and vertebral bodies. High interlaminar shear stresses were found in the posterolateral regions of the lumbar disks. While the facet joints of the upper two lumbar segments did not transmit any load, the facet joints of the lower two lumbar segments experienced significant loads. The ligaments of all lumbar motion segments except the lumbosacral junction provided only marginal moments. The limitations of the current model and possible improvements are discussed.

    2012-01-01

    Full Text Available Intradural extra-arachnoid lumbar disc herniation is a rare disease. Few MRI findings have been reported. We experienced an intradural extra-arachnoid lumbar disc herniation. We reviewed the preoperative MRI findings. Lumbar spine T2-weighted sagittal MRI showed that one line of the ventral dura was divided into two by a disc herniation. We speculated that the two lines comprised the dura and arachnoid and that a disc herniation existed between them. We believe that division of the ventral dural line on T2-weighted sagittal images is a characteristic finding of intradural extra-arachnoid lumbar disc herniation. The division of ventral dural line seemed to be a “Y,” and, thus, we called it the “Y sign.” The “Y sign” may be useful for diagnosing intradural extra-arachnoid lumbar disc herniation.

  9. Asymmetry of the multifidus muscle in lumbar radicular nerve compression

    International Nuclear Information System (INIS)

    The multifidus muscle is the only paraspinal lumbar muscle that is innervated by a single nerve root. This study aimes to evaluate if the asymmetry of the multifidus muscle is related to the severity of compression of the nerve root or the duration of radiculopathy. MRI scans of 79 patients with symptomatic single level, unilateral, lumbar radiculopathy were reviewed for this retrospective case series with a nested case-control study. The cross-sectional area (CSA) of the multifidus muscle and the perpendicular distance of the multifidus to the lamina (MLD) were measured bilaterally by two radiologists and set into relation to the severity of nerve compression, duration of radiculopathy and probability of an indication for surgical decompression. In 67 recessal and 12 foraminal symptomatic nerve root compressions, neither the MLD ratio (severe 1.19 ± 0.55 vs less severe nerve compression: 1.12 ± 0.30, p = 0.664) nor the CSA ratio (severe 1 ± 0.16 vs less severe 0.98 ± 0.13, p = 0.577) nor the duration of symptoms significantly correlated with the degree of nerve compression. MR measurements of multifidus were not different in patients with (n = 20) and those without (n = 59) clinical muscle weakness in the extremity caused by nerve root compression. A MLD >1.5 was, however, associated with the probability of an indication for surgical decompression (OR 3, specificity 92 %, PPV 73 %). Asymmetry of the multifidus muscle correlates with neither the severity nor the duration of nerve root compression in the lumbar spine. Severe asymmetry with substantial multifidus atrophy seems associated with the probability of an indication of surgical decompression. (orig.)

    An MRI unit for interventional procedure is very useful for minimally invasive surgery of the brain and spine. Percutaneous laser disc decompression (PLDD) utilizing X-ray fluoroscopy is a relatively new less invasive procedure for treatment of lumbar disc herniation. MR guided laser surgery is applied to patients with disc herniation at our department. Approaching the target of the disc protrusion was easily conducted and vaporizing the disc hernia directly using a laser was possible under MR fluoroscopy. The purpose of the present study is to evaluate the usefulness of MR guided percutaneous laser disc hernia ablation (MR-guided PLDHA). As subjects, 36 patients with lumbar disc herniation, including 23 cases with L4/5 involvement and 13 cases with L5/S1 involvement were studied. Among these, 26 were males and 10 were females, age ranging from 24 to 62. We used an open type MR system (Hitachi, Airis 0.3T), a permanent, open configuration MR system. A YAG laser (LaserScope, USA) was used for PLDHA. An MR compatible 18G titanium needle 15 cm in length was used to puncture the herniated discs. The MR compatible needle was clearly visualized, and used to safely and accurately puncture the target herniated disc in each case with multidimensional guidance. Application of the laser was performed with MR guidance. The energy dose from the laser ranged from 800 to 2100 joules. In most cases, signs and symptoms improved in the patients immediately after disc vaporization. The overall success rate was 88.9%. The complication rate was 2.8%, including one case of discitis after PLDHA. MR fluoroscopy sequence permits near real time imaging and provides an easy approach to the therapeutic target of disc herniation. MR guided PLDHA is a minimally invasive procedure and is very useful for the treatment of lumbar disc protrusion. (author)

    Full Text Available Background: Transforaminal lumbar endoscopic discectomy (TLED is a minimally invasive procedure for removing lumbar disc herniations. This technique was initially reserved for herniations in the foraminal or extraforaminal region. This study concentrated on our experience regarding the outcomes and efficacy of TLED. Materials and Methods: A total of 105 patients were included in the study. The patients were retrospectively evaluated for demographic features, lesion levels, numbers of affected levels, visual analog scores (VASs, Oswestry disability questionnaire scale scores and MacNab pain relief scores. Results: A total of 48 female and 57 male patients aged between 25 and 64 years (mean: 41.8 years underwent TLED procedures. The majority (83% of the cases were operated on at the levels of L4-5 and L5-S1. Five patients had herniations at two levels. There were significant decreases between the preoperative VAS scores collected postoperatively at 6 months (2.3 and those collected after 1-year (2.5. Two patients were referred for microdiscectomy after TLED due to unsatisfactory pain relief on the 1 st postoperative day. The overall success rate with respect to pain relief was 90.4% (95/105. Seven patients with previous histories of open discectomy at the same level reported fair pain relief after TLED. Conclusions: Transforaminal lumbar endoscopic discectomy is a safe and effective alternative to microdiscectomy that is associated with minor tissue trauma. Herniations that involved single levels and foraminal/extraforaminal localizations were associated with better responses to TLED.

  14. The diagnostic utility of resistive MRI for lumbar disc hernias

    International Nuclear Information System (INIS)

    The diagnostic utility of the 0.1 tesla resistive magnetic resonance imaging (MRI) system was studied for 78 lumbar disc hernias in surgically treated 70 patients. Myelographic appearance of the lumbar disc hernias fell into the following three categories: (1) medial type, compressing the thecal sac; (2) mediolateral type, compressing both the nerve root and thecal sac; and (3) lateral type, compressing the nerve root. MRI was performed in low-flip angle (LF) and saturation-recovery (SR) radiofrequency-pulse sequences for the midline and paramedian sagittal sections, respectively. A transverse section was found positive when the laterality of the disc hermia was obtained. A coronal section was found positive when high-intensity disc material compresisng the nerve root was recognized. Diagnostic capability of MRI was graded in three scores: Excellent- the optimal information was provided; Fair- some pieces of information was obtained, but not enough for diagnosis; Poor- the information was not helpful for diagnosis in deciding the operative procedure. Of 13 medial disc hernias, 84.6% was positive in the sagittal plane and 88.9% in the transverse plane. MRI was superior to myelography in 9 lesions. Of 38 mediolateral disc hernias, 84.2% were positive in the sagittal plane, 74.2% in the transverse plane, and 26.7% in the coronal plane. MRI was judged as excellent for 17 lesions, fair for 15 lesions, and poor for 6 lesions. Of 27 lateral disc hernias, 55.6% were positive in the sagittal plane, 50.0% in the transverse plane, and 30.0% in the coronal plane. MRI was judged as excellent for 4 lesions, fair for 11 lesions, and poor for 12 lesions. Resistive MRI system was of limited value in diagnosing surgical indication of lateral lumbar disc hernias, especially for small but painful lesions. (N.K.)

  15. Ultrastructural changes of compressed lumbar ventral nerve roots following decompression

    International Nuclear Information System (INIS)

    To study whether there will be permanent lumbar nerve rot scanning or degeneration secondary to continuous compression followed by decompression on the nerve roots, which can account for postlaminectomy leg weakness or back pain. The study was performed at the Department of Anatomy, Faulty of Medicine, king Abdulaziz University, Jeddah, Kingdom of Saudi Arabia during 2003-2005. Twenty-six adult male New Zealand rabbits were used in the present study. The ventral roots of the left fourth lumbar nerve were clamped for 2 weeks then decompression was allowed by removal of the clips. The left ventral roots of the fourth lumbar nerve were excised for electron microscopic study. One week after nerve root decompression, the ventral root peripheral to the site of compression showed signs of Wallerian degeneration together with signs of regeneration. Schwann cells and myelinated nerve fibers showed severe degenerative changes. Two weeks after decompression, the endoneurium of the ventral root showed extensive edema with an increase in the regenerating myelinated and unmyentilated nerve fibers, and fibroblasts proliferation. Three weeks after decompression, the endoneurium showed an increase in the regenerating myelinated and unmyelinated nerve fibers with diminution of the endoneurial edema, and number of macrophages and an increase in collagen fibrils. Five and 6 weeks after decompression, the endoneurium showed marked diminution of the edema, macrophages, mast cells and fibroblasts. The enoneurium was filed of myelinated and unmyelinated nerve fibers and collagen fibrils. Decompression of the compressed roots of a spinal nerve is followed by regeneration of the nerve fibers and nerve and nerve recovery without endoneurial scarring. (author)

    Twenty persons with chronic low back pain participated in a clinical study to evaluate the effects of gravity traction. Each subject was instructed in the use of three devices, two for inversion and one for upright suspension traction. Baseline pulse and rate blood pressure were recorded before and after traction. Periods of traction did not exceed 20 minutes. The order of use of the devices was randomized. Each participant was monitored for significant side effects and was questioned to determine which device was best tolerated, easiest to use, or caused changes in back symptoms. Lateral lumbar spine radiographs were taken with the subject in the standing position and after varying periods of inversion. Observations included the following: An average increase in blood pressure of 17.2 systolic (range 4-34) and 16.4 diastolic (range 2-50) while in the inverted position. An average decrease in heart rate of 16.4 beats per minute (range, 4-32). No significant physiologic changes of blood pressure or pulse were observed in patients using GLR suspension traction; distraction of the lower lumbar intervertebral spaces (range, 0.3 to 4.0 mm) with inverted traction in all cases; side effects including periorbital and pharyngeal petechiae (one patient), persistent headaches (three patients), persistent blurred vision (three patients), and contact lense discomfort (one patient); and improvement of low back symptoms in 13 of the 16 symptomatic patients. Although these devices make lumbar traction practical in a home setting, their use should be under medical supervision because of possible side effects. PMID:3155939

    Objectives: To examine general practitioners' attitudes to plain lumbar spine radiographic examinations. Design: A postal questionnaire consisting of questions on background data and doctors' opinions about plain lumbar spine radiographic examinations, as well as eight vignettes (imaginary patient cases) presenting indications for lumbar radiography, and five vignettes focusing on the doctors' willingness to request lumbar radiography on the basis of patients' age and duration of symptoms. The data were analysed according to the doctor's age, sex, workplace and the medical school of graduation. Setting: Finland. Subjects: Six hundred and fifteen randomly selected physicians working in primary health care (64% of original target group). Results: The vignettes revealed that the use of plain lumbar radiographic examination varied between 26 and 88%. Patient's age and radiation protection were the most prominent factors influencing doctors' decisions to request lumbar radiographies. Only slight differences were observed between the attitudes of male and female doctors, as well as between young and older doctors. Doctors' willingness to request lumbar radiographies increased with the patient's age in most vignettes. The duration of patients' symptoms had a dramatic effect on the doctor's decision: in all vignettes, doctors were more likely to request lumbar radiography when patient's symptoms had exceeded 4 weeks. Conclusions: General practitioners commonly use plain lumbar spine radiographic examinations, despite its limited value in the diagnosis of low back pain. Further consensus and medical education is needed to clarify the indications for plain lumbar radiographic examination.

    Full Text Available Background: Lumbar spine facet joints are arranged sagittally and mainly provide forward flexibility. Rotation of the lumbar vertebral body and coronal plane deformity may influence the function of lumbar forward flexibility. We hypothesize that the more advanced axial and coronal plane deformity could cause more limitation on forward flexibility in patients with idiopathic scoliosis. Methods: Between January 2011 and August 2011, 85 patients with adolescent idiopathic scoliosis were enrolled in this study. The proximal thoracic, major thoracic, thoracolumbar/lumbar (TL/L, and lumbar (L1/L5 curves were measured by Cobb's method. Lumbar apical rotation was graded using the Nash-Moe score. Lumbar forward flexibility was measured using the sit and reach (S and R test. Statistical analysis was performed using one-way analysis of variance (ANOVA, Spearman's and Pearson's correlation coefficients. Results: The mean age was 16.1 ± 2.84 years. The mean proximal thoracic, major thoracic, TL/L, and L1/L5 curves were 17.61° ± 8.92, 25.56° ± 11.61, 26.09° ± 8.6, and 15.10° ± 7.85, respectively. The mean S and R measurement was 25.56 ± 12.33 cm. The magnitude of the TL/L and L1/L5 curves was statistically positively related to vertebral rotation (rs = 0.580 and 0.649, respectively. The correlation between the S and R test and both the TL/L and L1/L5 curves was negative (rp = –0.371 and –0.595, respectively. Besides, the S and R test also demonstrated a significant negative relationship with vertebral rotation (rs = –0.768. Conclusion: In patients with idiopathic scoliosis, spinal deformity can diminish lumbar forward flexibility. Higher lumbar curvature and rotation lead to greater restriction of lumbar flexion.

  19. CT findings of lumbar intervertebral disc: II. Disc herniation (HNP)

    International Nuclear Information System (INIS)

    In lumbar region the epidural fat pad is relatively abundant so that CT can provides sufficient information in diagnosis of lumbar HNP. Many authors have reported on the CT findings of HNP such as focal nodular protrusion of the posterior disc margin, obliteration of epidural fat pad, impingement of dural sac and nerve root, swelling of nerve root, soft tissue density in the spinal canal and calcification of disc. However there was so previous report describing incidence and reliability of the findings. It is the purpose of the present study to survey the frequency, reliability, and limitation of these CT findings. The clinical material was consisted of 30 operatively proven cases of HNP of the lumbar spine. Each lumbar CT scan was reviewed retrospectively and the findings were analysed by two radiologists independently. There were 20 males and 10 females and the mean age was 36.7 years. Involvement of L4-S5 level was 2.3 times more frequent than that of L5-S1 level. Of 30 cases, 22 were unilateral posterolateral types and 8 cases central or unilateral far lateral types. CT findings observed were nodular protrusion of the posterior margin of the disc, obliteration of epidural fat pad, impingement of dural sac or nerve root, soft tissue density in the spinal canal and calcification in the posterior portion of the protruded disc, in order of decreasing frequency. The conclusions are follows: 1. Nodular protrusion of the posterior disc margin accompanied by obliteration of epidural fat pad was observed in every case. The former findings was designated as direct sign and the latter indirect. 2. Obliteration of the epidural fat appears to be significant in lateral recesses especially when it occurs unilaterally. This was not true, however, in the centrally located fat pad. 3. Impingement of the dural sac and nerve root were observed in 90% and 67%, respectively, and were very helpful in establishing HNP diagnosis when the direct and indirect signs were equivocal

    Persistent postsurgical pain (PPSP) affects between 10% and 50% of surgical patients, the development of which is a complex and poorly understood process. To date, most studies on PPSP have focused on specific surgical procedures where individuals do not suffer from chronic pain before the surgical intervention. Individuals who have a chronic nerve injury are likely to have established peripheral and central sensitization which may increase the risk of developing PPSP. Concurrent analyses of the possible factors contributing to the development of PPSP following lumbar discectomy have not been examined.

    Since November 88, 28 patients with lumbar L5 radiculopathy refractory to conservative care and with a radiologically verified central or mediolateral disc herniation at the level of L4/L5 had had a percutaneous discectomy. A short-term follow-up analysis of at least 2 months taking the clinical and functional status as well as the professional reintegration into account revealed a 64.3% (18/28 patients) satisfactory outcome and a 32.1% (10/28 patients) failure rate. Of the latter 28.6% (8/28 patients) required further open surgery. (orig./GDG).

    Full Text Available The identification of a soft tissue chondroma within the spine represents a rarity and is typically not included within the differential diagnosis for patients with sensory complaints of the leg. The authors describe 46-year-old female presenting with 3-week history of decreased sensation and paresthesias of the left leg. Magnetic resonance imaging of the lumbar spine demonstrated an L3 extradural soft tissue mass. She underwent an uncomplicated excision through an L3 laminectomy and exhibited complete resolution of symptoms. Pathologic examination revealed benign cartilaginous tissue; however, the authors recommend long-term follow-up for such lesions as the potential for malignant transformation is unknown.

    Hematoma of the lumbar ligamentum flavum is a very rare cause of sciatica. A 72-year-old man presented with left-sided sciatica and paresthesia of the lateral aspect of his left foot. From CT and MRI findings, he was diagnosed as having a hematoma embedded in the ligamentum flavum, which compressed the dura mater at the L5/S1 disc level. After an adequate surgical field was obtained with a microscope and a Casper retractor, the hematoma of the ligamentum flavum could be excised via a unilateral approach and satisfactory decompression of the cauda equina and nerve roots were obtained.

  4. CT findings of lumbar intervertebral discs: I. normal anatomy

    International Nuclear Information System (INIS)

    The cross-sectional anatomy of the intervertebral disc and spinal canal can be studied in detail by computed tomography (CT) which is not invasive and is much simpler than conventional myelography. The shape of the normal disc and distribution of epidural fat pad varied at each disc level and CT findings of the normal disc and spinal canal are essential in diagnosis of herniation or bulging. However, there has been no previous publications providing us with the detailed criteria of normal disc and neural canal cross-sectional anatomy. The present study has been carried out to investigate CT anatomy of the normal distribution of the epidural fat at each lumbar disc level to set up a baseline by which one will be able to judge disc herniation or bulging. The materials consisted of 30 adult volunteers. They were sampled randomly from the individual undergoing a CT study for the reasons other than spinal disease and having no symptoms or signs of the lumbar spinal disease. CT scans were performed with a Siemens Somatom 2 Scanner. Technical factors involved were: Tube voltage 125 kVp, exposure time 10 seconds, 460 mAS, 256 x 256 matrix, and pixel size 0.4 mm. Contiguous 2-mm thick slice of each disc were obtained parallel to the disc plane at 3-mm interval for 5 lumbar disc. The results are follows: 1. The shape of the posterior disc margins at L1-2, L2-3, and L3-4 levels were concave anteriorly in over 90% of the cases compared with the disc margins at L4-5 and L5-S1 where were convex or flat in over 85%. 2. None of the convex disc showed focal nodular protrusion nor were more convex than anterior margin of the disc. 3. The lower lumbar levels, the greater the visibility of the epidural fat pad. The visibility of the epidural fat pad in both lateral recesses was 81.5% at the L4-5 level and 100% at the L5-S1 level. There was no single case in which epidural fat pad was visable in only on side. 4. The visibility of the epidural fat just behind the disc was only 18.5% at

    Full Text Available Juxtafacet cysts are an uncommon cause of radiculopathy. They occur most frequently in the lumbar region, and their distribution across the spine correlates with mobility. Haemorrhagic complications are rare and may occur in the absence of any provocation, although there is some association with anticoagulation and trauma. We present a case of acute radiculopathy due to an L5/S1 juxtafacet cyst with unprovoked haemorrhage which was found to extend into ligamentum flavum. The patient underwent uncomplicated microscope assisted decompression with excellent results. The demographics, presentation, aetiology, and management of juxtafacet cysts are discussed.

    OBJECT There are a variety of surgical positions that provide optimal exposure of the dorsal lumbar spine. These include the prone, kneeling, knee-chest, knee-elbow, and lateral decubitus positions. All are positions that facilitate exposure of the spine. Each position, however, is associated with an array of unique complications that result from excessive pressure applied to the torso or extremities. The authors reviewed clinical studies reporting complications that arose from positioning of the patient during dorsal exposures of the lumbar spine. METHODS MEDLINE, Scopus, and Web of Science database searches were performed to find clinical studies reporting complications associated with positioning during lumbar spine surgery. For articles meeting inclusion criteria, the following information was obtained: publication year, study design, sample size, age, operative time, type of surgery, surgical position, frame or table type, complications associated with positioning, time to first observed complication, long-term outcomes, and evidence-based recommendations for complication avoidance. RESULTS Of 3898 articles retrieved from MEDLINE, Scopus, and Web of Science, 34 met inclusion criteria. Twenty-four studies reported complications associated with use of the prone position, and 7 studies investigated complications after knee-chest positioning. Complications associated with the knee-elbow, lateral decubitus, and supine positions were each reported by a single study. Vision loss was the most commonly reported complication for both prone and knee-chest positioning. Several other complications were reported, including conjunctival swelling, Ischemic orbital compartment syndrome, nerve palsies, thromboembolic complications, pressure sores, lower extremity compartment syndrome, and shoulder dislocation, highlighting the assortment of possible complications following different surgical positions. For prone-position studies, there was a relationship between increased

    Ganglioneuroma is a rare, benign, slow-growing, well-differentiated tumor consisting of ganglion cells and Schwann cells. Ganglioneuromas originate from neural crest cells and can affect any part of the sympathetic tissue from the skull base to the pelvis. However, ganglioneuroma occurring in the nerve root is extremely rare. We describe a 50-year-old man with ganglioneuroma involving the right 5th lumbar nerve root. The ganglioneuroma showed intermediate signal intensity on the T1-weighted image and high signal intensity on the T2-weighted image with homogeneous enhancement on the gadolinium-enhanced T1-weighted image.

    Concerning the Modic change of lumbar spinal endplate, the Modic change types, forming causes, and the relationship between Modic change and degenerative lumbar diseases have been studied from anatomy, pathology, molecular biology and many other aspects at present. The degeneration of lumbar disc is a high risk factor of the Modic change. The degeneration of lumbar disc usually starts from cartilage endplate degeneration. The injury of cartilage endplate could accelerate the degeneration of lumbar disc. This article reviews the significance of Modic change of lumbar spinal endplate in lumbar disc degeneration. The cause of Modic change of the endplate, pathological change, the influence of inflammatory mediators on the endplate and the significance of Modic change in the treatment of degenerative lumbar diseases are summarized to analyze the relationship between the degeneration of lumbar disc and Modic change of endplate and to describe the influence of Modic change in the treatment of degenerative lumbar disc diseases.

    Full Text Available Background: Epidural steroid injection (ESIs is one of the treatment modalities for chronic low back pain (CLBP with various degrees of success. Aim: We analyzed the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESIs via a preganglionic approach in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy. Materials and Methods: We analyzed the data of 40 patients (February 2008 and April 2009 with the diagnosis of CLBP and treated by fluoroscopically guided TFESIs via a preganglionic approach. Patients were followed-up at one month (short term, six months (midterm and one year (long term after injections. Follow-up data collection included the Visual Numeric Pain Scale (VNS and North American Spine Society (NASS patient satisfaction scores. Results: The mean age of the patients was 59.87 ± 15.06 years (range 30 - 89 years, 25 women. Average follow-up period was 9.22 ± 3.56 months. Statistically significant differences were observed between the pre-procedure and post-procedure VNSs (P < 0.01, Pearson Correlation Test. Improvements in VNS scores were correlated with improvements in the NASS scores. When the VNS scores were evaluated with respect to the age of patient, level numbers, gender, pre-procedure symptom duration and pre-procedure VNS, no significant differences were found (P < 0.05, linear regression test. At short term evaluation in post treatment (one month, 77.78 % of patients were found to have a successful outcome and 22.22 % were deemed failures. Overall patient satisfaction was 67.23 % in the midterm period. Additionally, 54.83 % of patients (N/n: 15/8 had a successful long-term outcome at a follow-up of one year. Conclusion: Our data suggest that fluoroscopically guided TFESIs via a preganglionic approach, in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy, has effective outcome and
