ABSTRACT

OBJECTIVE@#To review the research progress of Modic changes and its influence on lumbar interbody fusion.@*METHODS@#The domestic and foreign literature related to Modic changes and its influence on lumbar interbody fusion was extensively reviewed. The etiology of Modic changes was summarized, and the treatment measures of Modic changes on lumbar interbody fusion were discussed.@*RESULTS@#The etiology of Modic changes is not clear, which may be related to mechanical factors, autoimmune factors, low toxic infection factors, and genetic factors. Modic changes may lead to fusion failure and cage subsidence after lumbar interbody fusion. Preoperative evaluation of endplate sclerosis, reduction of iatrogenic endplate injury, fine operating of intervertebral space, management of osteoporosis, and selection of appropriate cage can prevent or reduce fusion failure or cage subsidence.@*CONCLUSION@#Modic changes may lead to fusion failure and cage subsidence after lumbar interbody fusion, and active perioperative intervention of Modic changes is helpful to improve the clinical prognosis.

ABSTRACT

ABSTRACT Objectives To evaluate pain intensity and functional status before and 30 days following percutaneous lumbar endoscopic discectomy. Methods A retrospective cohort study that included patients who underwent percutaneous endoscopic discectomy from January 2019 to October 2020 at the Irmandade Santa Casa de Misericórdia Hospital, in Porto Alegre. The data were collected from the electronic medical records of the patients by two independent physicians. Clinical outcomes were assessed using visual analog scale (VAS) and Oswestry Disability Index (ODI) scores. Results Forty-six patients with a mean age of 52.6 ± 15.8 years, 27 of whom (58.7%) were male, were evaluated. Regarding clinical outcomes, a statistically significant improvement was observed in the comparison between the pre- and 30-day postoperative VAS and ODI scores, with no significant difference in relation to sex. No peri- or postoperative complications were observed. All patients successfully completed surgery and were discharged after recovery from anesthesia. Conclusion There was a significant improvement in pain and functional status 30 days after percutaneous endoscopic discectomy performed to correct lumbar disc herniation, with no difference in relation to sex. In addition, no peri- or postoperative complications were observed. Future studies, with longer follow-up times, comparing clinical outcomes from the various techniques of percutaneous endoscopic discectomy are necessary. Level of evidence III; Retrospective comparative study.

ABSTRACT

A captive adult male bush dog (Speothos venaticus) was referred to our Veterinary Medical Teaching Hospital from a local zoo due to a two-week history of progressive hind limb gait impairment and ataxia, non-responsive to clinical management. Computed tomography revealed decreased disc space at L3 - L4 level, with probable disc extrusion narrowing the right side of the spinal canal, compressing the spinal cord. We opted to surgically remove the disc material using both fenestration and right lateral pediculectomy (mini-hemilaminectomy) techniques. Twelve days after surgery there was mild residual proprioceptive ataxia. Gait was fully regained with remission of the neurological deficits around the 30th postoperative day. This is - to the best of our knowledge - the first successful report of a lumbar intervertebral disc extrusion in a bush dog (Speothos venaticus) surgically treated by pediculectomy and disc fenestration.(AU)


Um cachorro-vinagre (Speothos venaticus), macho, adulto, mantido em cativeiro, foi encaminhado ao Hospital Veterinário Universitário pelo zoológico local com histórico de duas semanas de comprometimento progressivo da marcha dos membros posteriores e ataxia, que não responderam ao tratamento clínico. Tomografia computadorizada revelou diminuição do espaço em disco no nível L3 - L4, com provável extrusão de disco estreitando o lado direito do canal vertebral, comprimindo a medula espinhal. Optamos por remover cirurgicamente esse material do disco usando técnicas de fenestração e pediculectomia lateral direita (mini-hemilaminectomia). Doze dias após a cirurgia, houve melhora na deambulação, com ataxia proprioceptiva residual leve. A marcha foi totalmente recuperada com remissão dos déficits neurológicos por volta do trigésimo dia de pós-operatório. Este é - até onde sabemos - o primeiro relato bem-sucedido de uma extrusão de disco intervertebral lombar em um cachorro-vinagre (Speothos venaticus) tratado cirurgicamente por pediculectomia e fenestração de disco.(AU)

ABSTRACT

Several surgical procedures aim to decompress and/or stabilize the lumbosacral (LS) joint of dogs; however, the lumbar interbody fusion technique, by using a cage combined with a bone graft, is the most indicated and used in human medicine. No specific implant is available for application to the canine lumbosacral joint. Thus, this study measured lumbosacral discs in large dogs, determined whether a human cage model could fit the dogs' L7-S1 intervertebral space, and developed a LS cage prototype for dogs. Ten cadaveric lumbosacral spines from adult dog weighing 20-35kg were used. The dogs had died for reasons unrelated to this study. The vertebral body dimensions and the L7-S1 intervertebral space occupied by the intervertebral disc were measured by lateral and ventrodorsal radiographs and by computed tomography in the dorsal, sagittal, and transverse views. Measurements were also taken of the anatomical specimens in the sagittal and transverse planes. After measuring the intervertebral discs, the following mean measures were obtained for L7-S1 discs: height 12.23mm, dorsal thickness 3.3mm, central thickness 4mm, ventral thickness 5.5mm, and width 24.74mm. The human lumbar cage models from brands LDR, Baumer Orthopedics, Stryker, Synthes, and Vertebral Technologies, Inc. and cervical stabilization cages from the brands B-Braun and Stryker were evaluated and were found to be unsuitable for large dogs. Cervical human cages had measurements similar to those found in this study; however, due to their quadrangular shape, the possibility of being introduced surgically through the surgical accesses available for the articulation between L7-S1 in dogs without injuring the cauda equina or the L7 root is small. A cage model was then developed using 3D modelling software. It was designed for insertion via dorsal laminectomy in the lateral portions of the intervertebral space. To avoid cauda equina lesion, the implant model was developed to be placed laterally to the midline. The cage surface is serrated to prevent using the locking screw to fix it, thus avoiding further injury to nerve structures. The serrated surfaces are also designed to avoid cage migration and promote stability. The prototype allows graft placement in the surrounding intervertebral space, which is fundamental for fusion through integration between the cage and the endplates as well as for bone growth between and around the cage. It was also considered studies on humans showing that the lateral regions of the endplates support a more considerable load. Biomechanical and in vivo studies on the developed model are necessary to evaluate the actual degree of distraction, mobility and the long-term rate of fusion between L7 and S1 and its possible impact on the adjacent motor units, combined or not with dorsal fixation techniques.(AU)


Vários procedimentos cirúrgicos visam descomprimir e/ou estabilizar a articulação lombossacra (LS) de cães; no entanto, a técnica de fusão lombar, usando um cage intersomático combinado com um enxerto ósseo, é a mais indicada e utilizada na medicina humana. Não há implante específico disponível para aplicação na articulação lombossacra canina. Assim, neste estudo foi realizada a mensuração do espaço do disco intervertebral lombossacro de cães de raças grandes, para verificar se algum modelo de cage usado na medicina humana poderia ser usado no espaço intervertebral L7-S1 de cães. O segundo objetivo foi desenvolver um protótipo de cage lombossacro para cães. Foram utilizadas dez colunas lombossacras provenientes de cadáveres de cães adultos com peso entre 20 e 35kg. Os cães vieram a óbito por razões não relacionadas a este estudo. As dimensões do corpo vertebral e o espaço intervertebral L7-S1 ocupado pelo disco intervertebral foram medidos por radiografias laterais e ventrodorsais e por tomografia computadorizada nos cortes dorsal, sagital e transversal. Também foram realizadas mensurações das peças anatômicas nos planos sagital e transversal. Após a mensuração dos discos intervertebrais, foram obtidas as seguintes medidas médias dos discos L7-S1: altura 12,23mm, espessura dorsal 3,3mm, espessura central 4mm, espessura ventral 5,5mm e largura 24,74mm. Os modelos de cage lombar humano das marcas LDR, Baumer Orthopaedics, Stryker, Synthes e Vertebral Technologies, Inc. não possuíam dimensões adequadas para os cães. Cages de estabilização cervical das marcas B-Braun e Stryker também foram avaliados e apresentaram medidas semelhantes às encontradas neste estudo; no entanto, devido à sua forma quadrangular, a possibilidade de serem introduzidos cirurgicamente através das abordagens disponíveis para a articulação entre L7-S1 em cães sem lesionar a cauda equina ou a raiz L7 é pequena. Um modelo de cage foi então desenvolvido usando-se o software de modelagem 3D. Foi projetado para inserção via laminectomia dorsal nas porções laterais do espaço intervertebral. Para evitar a lesão da cauda equina, o modelo de implante foi desenvolvido para ser colocado lateralmente à linha média. A superfície do cage é serrilhada para evitar o uso do parafuso de travamento, evitando-se lesões adicionais às estruturas nervosas. As superfícies serrilhadas também foram projetadas para evitar a migração do cage e promover estabilidade. O protótipo permite a colocação do enxerto no espaço intervertebral circundante, fundamental para a fusão através da integração entre o cage e as placas vertebrais terminais, bem como para o crescimento ósseo entre e ao redor do implante. Também foram considerados estudos em seres humanos que mostraram que as regiões laterais das placas vertebrais terminais suportam uma carga maior. São necessários estudos biomecânicos e in vivo do modelo desenvolvido para avaliar o grau real de distração, mobilidade e a taxa de fusão a longo prazo entre L7 e S1 e seu possível impacto nas unidades motoras adjacentes, quando combinado ou não com técnicas de fixação dorsal.(AU)

ABSTRACT

Introduction Technical developments in spinal surgery have reduced the number of surgical incisions and of the length of time for the procedure. Objective Describe topographical landmarks, anatomy and characteristics of the Wiltse access, a paraspinal approach to the lumbar spine. Methods A review of the literature was performed using as databases: PubMed, Embase, Science Direct, the Cochran Database and Google Scholar. Total 22 papers met the inclusion criteria, and they were all published between 1959 and 2016. Discussion The Wiltse approach is performed by median skin incision with lateral muscle dissection between the multifidus and the longissimus muscles, in a natural pathway. This approach allows access to the pedicles and to the lateral recess, enabling the performance of posterior spinal fusion and decompression and minimally invasive discectomy techniques. This access is less traumatic than the median approach, and it is ideal for lower levels, like L4­5 and L5-S1. Conclusion The authors strongly encourage this approach because they believe that, when well-indicated, the benefits outweigh the disadvantages and complications due to the fact that it is a less invasive procedure.


Introdução Os desenvolvimentos técnicos na cirurgia da coluna vertebral têm proporcionado a redução das incisões cirúrgicas e da duração do procedimento. Objetivo Descrever marcos topográficos, anatômicos e características do acesso de Wiltse, uma abordagem da coluna vertebral lombar. Métodos A revisão bibliográfica foi realizada utilizando como banco de dados: PubMed, Embase, Science Direct, banco de dados Cochran e Google Scholar. Foram encontrados 22 trabalhos que atenderam aos critérios de inclusão, todos publicados entre 1959 e 2016. Discussão A abordagem de Wiltse é realizada pela incisão cutânea mediana com dissecção muscular lateral entre o músculo multifidus e o músculo longissimus, na via natural. Esta abordagem permite o acesso aos pedículos e ao recesso lateral, e a realização de fusão posterior e descompressão de fratura da coluna vertebral e técnicas de discectomia minimamente invasivas. Este acesso é menos traumático do que a abordagem mediana, e é ideal para níveis mais baixos, como L4­5 e L5-S1. Conclusão Os autores recomendam esta abordagem, pois acreditam que os benefícios desta técnica, quando bem indicada, superam as desvantagens e complicações por ser esta menos invasiva.

ABSTRACT

BACKGROUND: For surgical treatment of lumbar and lumbosacral tuberculosis, the anterior approach has been the most popular approach because it allows direct access to the infected tissue, thereby providing good decompression. However, anterior fixation is not strong, and graft failure and loss of correction are frequent complications. The posterior approach allows circumferential decompression of neural elements along with three-column fixation attained via pedicle screws by the same approach. The purpose of this study was to evaluate the outcome (functional, neurological, and radiological) in patients with lumbar and lumbosacral tuberculosis operated through the posterior approach. METHODS: Twenty-eight patients were diagnosed with tuberculosis of the lumbar and lumbosacral region from August 2012 to August 2013. Of these, 13 patients had progressive neurological deterioration or increasing back pain despite conservative measures and underwent posterior decompression and pedicle screw fixation with posterolateral fusion. Antitubercular therapy was given till signs of radiological healing were evident (9 to 16 months). Functional outcome (visual analogue scale [VAS] score for back pain), neurological recovery (Frankel grading), and radiological improvement were evaluated preoperatively, immediately postoperatively and 3 months, 6 months, and 1 year postoperatively. RESULTS: The mean VAS score for back pain improved from 7.89 (range, 9 to 7) preoperatively to 2.2 (range, 3 to 1) at 1-year follow-up. Frankel grading was grade B in 3, grade C in 7, and grade D in 3 patients preoperatively, which improved to grade D in 7 and grade E in 6 patients at the last follow-up. Radiological healing was evident in the form of reappearance of trabeculae formation, resolution of pus, fatty marrow replacement, and bony fusion in all patients. The mean correction of segmental kyphosis was 9.85° postoperatively. The mean loss of correction at final follow-up was 3.15°. CONCLUSIONS: Posterior decompression with instrumented fusion is a safe and effective approach for management of patients with lumbar and lumbosacral tuberculosis.

ABSTRACT

The major problems of revision surgery for recurrent lumbar disc herniation (LDH) include limited visualization due to adhesion of scar tissue, restricted handling of neural structures in insufficient visual field, and consequent higher risk of a dura tear and nerve root injury. Therefore, clear differentiation of neural structures from scar tissue and adhesiolysis performed while preserving stability of the remnant facet joint would lower the risk of complications and unnecessary fusion surgery. Biportal endoscopic spine surgery has several merits including sufficient magnification with panoramic view under very high illumination and free handling of instruments normally impossible in open spine surgery. It is supposed to be a highly recommendable alternative technique that is safer and less destructive than the other surgical options for recurrent LDH.

ABSTRACT

Introdução: Foot drop é uma fraqueza do músculo tibial anterior e pode ser sinal de hérnia discal lombar, lesão do nervo peroneal, distrofia muscular ou lesão cerebral parasagital. Lesão da raiz do quinto nervo lombar ou lesão do nervo peroneal são as causas mais freqüentes. Os autores apresentam um caso de “foot drop” em um paciente portador de hérnia discal no segmento L3-L4. Discutem sua fisiopatologia, diagnóstico, tratamento e prognóstico. Relato do caso: PTS. Masculino, 38 anos de idade, pedreiro. História de fraqueza no pé direito há três meses. Exame neurológico: Marcha claudicante à direita, diminuição da força muscular à direita (++/++++) e hipoestesia no trajeto radicular de L3 do membro inferior direito. TC e RM de coluna lombar demonstraram hérnia discal extrusa no espaço L3-L4. Resultado: Submetido à hemilaminectomia lombar e excisão da hérnia discal extrusa. Submetido à fisioterapia motora e ortese, com recuperação do pé caído. Conclusão: O foot drop pode ser decorrente lesão periférica (nervo peroneal), neurônio motor inferior, lesão cortical e distrofia muscular. Seu diagnóstico é através de eletroneuromiografia, TC, mieloTC e RM. Seu prognóstico tem sido considerado bom quando operado precocemente. Em nosso paciente houve demora na recuperação do quadro devido ao tempo de evolução do caso.


Introduction: Foot dropt is a tibialis anterior muscle weakness and may be caused by lumbar discopathy, fibular nerve injury, muscular dystrophy or cerebral parasagital lesion. Lesion on the 5th lumbar nerve root or fibular nerve injury are the most common causes. The authors present a case of foot drop associated with a herniated L3-L4 lumbar disc. Physiopathology, diagnosis, treatment and prognosis are discussed. Case Report: 38-year-old man with a 3-month history of right foot weakness. Neurological examination: right-sided claudication during gait, right-sided muscular weakness (++/++++) and L3-dermal territory hypoesthesia on his right leg. Lumbar CT and MRI revealed an extruded L3-L4 herniated disc. Results: Patient was submitted to lumbar hemilaminectomy and extruded herniated disc excision. Motor physiotherapy and orthesis were also performed, with foot drop recovery. Conclusions: Foot drop may be caused by peripheral lesion (fibular nerve), lower motor neuron, cortical lesion or muscular dystrophy. Diagnosis is performed with EMG, CT, mieloCT and MRI. Early surgery is associated with good prognosis. Our patient showed slow recovery due to a long case evolution.

Introducción: la estenosis lumbar degenerativa en pacientes adultos mayores constituye un grave problema de salud actual. El tratamiento quirúrgico parece ser el de mejor resultado, pero presenta la disyuntiva de si a todos los pacientes que padezcan esta enfermedad se les debe tratar con igual técnica. Objetivos: mostrar los resultados obtenidos en el tratamiento quirúrgico de la estenosis lumbar degenerativa en pacientes mayores de 65 años. Métodos: se realizó un estudio descriptivo prospectivo en pacientes mayores de 65 años con diagnóstico de estenosis lumbar degenerativa, en el Centro de investigaciones en Longevidad, Envejecimiento y Salud, entre el 1 de enero de 2009 y el 1 de enero de 2011 (ambos incluidos). La serie quedó constituida por 28 pacientes. Las variables estudiadas fueron: edad, sexo, sintomatología, localización, principales condiciones comorbidas, clasificación radiográfica y por resonancia magnética. Se seleccionó la técnica quirúrgica empleada atendiendo al área anatómica estenosada. Se empleó el índice de Oswestry y la escala Visual Analógica de dolor como instrumentos evaluadores. Resultados: predominó el sexo masculino (67,6 por ciento), la localización en dos niveles vertebrales, y las condiciones comorbidas cardiovasculares. El síntoma predominante mostró valores semejantes entre el dolor lumbar, el irradiado y la claudicación. El índice de Oswestry y la Escala Visual Analógica del dolor mostraron significativa mejoría en el posquirúrgico. Se obtuvo un 89,2 porciento de buenos resultados. Conclusiones: el empleo de laminectomía para las estenosis centrales y recalibraje para las de receso lateral parece ser adecuada(AU)


Introduction: degenerative lumbar spinal stenosis is a serious health problem in the older adults at present. The surgical treatment seems to attain better results, but the controversy is whether all the patients suffering the disease can be treated with this procedure or not. Objectives: to show the results of the surgical treatment of degenerative lumbar spinal stenosis in over 65 years-old patients. Methods: a prospective and descriptive study was carried out in patients aged over 65 years and diagnosed with degenerative lumbar spinal stenosis in the Center of Research on Old Age, Aging and Health from January 1st 2009 to January 1st, 2011. The series was finally made up of 28 patients. The study variables were age, sex, symptoms, location, main comorbid conditions, and classification according to radiographies and to magnetic resonance. The choice of the surgical technique depended on the stenosed anatomical area. The Oswestry Disability Index and the Analogue Visual Scale of pain were the evaluation instruments. Results: males (67.6 percent), the location of disease at two vertebral levels and comorbid cardiovascular conditions prevailed. The predominant symptom showed similar values among lumbar pain, the irradiated pain and claudication. Oswestry Disability Index and the Analog Visual Scale of pain showed the significant improvement of patient in the postsurgical period. Good results reached 89.2 perent. Conclusions: laminectomy for central stenosis and regaging for the lateral recess seem to be adequate(AU)


Introduction: des nos jours, la sténose lombaire dégénérative constitue un sérieux problème de santé chez les personnes âgées. La chirurgie paraît être le traitement le plus prometteur, mais une question se pose, est-ce que tous les patients atteints de cette maladie doivent être traités par la même technique? Objectif: le but de cette étude est de montrer les résultats obtenus avec le traitement chirurgical de la sténose lombaire dégénérative chez les personnes âgées de plus de 65 ans. Méthode: une étude descriptive prospective de patients âgés de plus de 65 ans, diagnostiqués de sténose lombaire dégénérative, a été réalisée au Centre de recherches sur la longévité, le vieillissement et la santé entre le 1e janvier 2009 et le 1e janvier 2011. La série a été conformée de 28 patients. Les variables en étude comprennent âge, sexe, symptomatologie, localisation, comorbidité, classification radiographique et RM. La technique chirurgicale a été déterminée en accord avec la localisation de la sténose; l'index d'Oswestry et l'Échelle visuelle analogique (EVA) de la douleur ont été utilisés comme instruments d'évaluation. Résultats: dans l'étude, quelques variables ont prédominé (67.6 pourcent du sexe masculin, localisation à deux niveaux vertébraux, comorbidité cardiovasculaire, irradiation de la douleur lombaire, et claudication). L'index d'Oswestry et l'Échelle visuelle analogique de la douleur ont montré une amélioration significative dans le post-chirurgical. En général, on a obtenu de très bons résultats (89.2 pourcent). Conclusions: Dans le cas de la sténose centrale et de la sténose latérale, la laminectomie et le récalibrage respectivement semblent être appropriées(AU)

ABSTRACT

BACKGROUND: Bioactive glass-ceramics have the ability to directly bind to bones and have been widely used as bone graft substitutes due to their high osteoconductivity and biocompatibility. CaO-SiO2-P2O5-B2O3 glass-ceramics are known to have good osteoconductivity and are used as bone graft extenders. METHODS: This study aimed to evaluate the effects of the resorbing properties of glass-ceramics in bone fusion after producing and analyzing three types of CaO-SiO2-P2O5-B2O3 glass-ceramics with high osteoconductivity that had enhanced resorption by having an increased B2O3 content. The three types of CaO-SiO2-P2O5-B2O3 glass-ceramics with B2O3 contents of 8.0, 9.0, and 9.5 weight % were designated and grouped as P20B80, P10B90, and P5B95, respectively. Glass-ceramic types were tested for fusion rates and bone formation by employing the lumbar 5-6 intertransverse process fusion model in 51 New Zealand male rabbits. Bioactivity was assessed by soaking in simulated body fluid (SBF). RESULTS: In vitro study results showed sufficient hydroxycarbonate apatite layer formation occurred for P20B80 in1 day, for P10B90 in 3 days, and for P5B95 in 5 days after soaking in SBF. For the rabbit lumbar spine posterolateral fusion model, the autograft group recorded a 100% fusion rate with levels significantly higher than those of P20B80 (29.4%), P10B90 (0%), and P5B95 (14.3%), with high resorbing properties. Resorbing property differences among the three glass-ceramic groups were not significant. Histological results showed new bone formation confirming osteoconductivity in all three types of glass-ceramics. Radiomorphometric results also confirmed the resorbing properties of the three glass-ceramic types. CONCLUSIONS: The high resorbing properties and osteoconductivity of porous glass-ceramics can be advantageous as no glass-ceramics remain in the body. However, their relatively fast rate of resorption in the body negatively affects their role as an osteoconductive scaffold as glass-ceramics are resorbed before bony fusion.

ABSTRACT

Um dos maiores problemas dos pacientes pós-cirurgia bariátrica é o excedente de pele nas regiões glútea e lombar. Somado a isso, há escassez de tecido para preencher a região glútea, que pode ser corrigida por vários métodos, entre eles a lipoenxertia ou, ainda, o implante de prótese isoladamente, nos casos em que não haja ptose. Se o contrário ocorre, essas opções tornam-se muito limitadas e pouco expressivas. O lifting glúteo com emprego de retalho fasciocutâneo em cambalhota permite resolver tanto a flacidez como o excesso de pele com ptose. Este trabalho tem por objetivo demonstrar a facilidade de confecção e a versatilidade de utilização do retalho glúteo em cambalhota para correção de flacidez das regiões glútea e lombar. Uma paciente foi submetida ao procedimento cirúrgico de lifting glúteo associado ao emprego de retalho fasciocutâneo desepidermizado em cambalhota, para correção de falta de preenchimento local. Melhora acentuada das regiões glútea e lombar foi obtida após a retirada do excesso de tecido superior, confecção de um retalho fasciocutâneo de pedículo inferior e tração da pele. Além disso, a rotação do retalho e sua fixação ao músculo glúteo melhoraram acentuadamente o contorno posterior da paciente, com pós-operatório bastante cômodo. Com morbidade mínima, foi retirado o excesso cutâneo e, concomitantemente, aumentada a região glútea com retalho autólogo, que é desprezado durante a execução de muitas técnicas, melhorando o contorno da paciente e deixando uma cicatriz discreta, que poderá ser ocultada pelas roupas íntimas.


A major problem for patients after bariatric surgery is the excess skin in the gluteal and lumbar regions. In addition, there is a lack of available tissue to fill the gluteal region, which can be overcome by various methods, including fat grafting or even prosthesis implantation alone, in cases where no ptosis is noted. However, if this is not the case, the options become very limited and those available are not very effective. The use of a buttock lift with a fasciocutaneous flap solves the problems of sagging and excess skin with ptosis. In the present article, we aimed to demonstrate the ease of preparation and the versatility of use of the gluteal flap to correct sagging of the lumbar and gluteal regions. One patient underwent a buttock lift using a de-epidermized fasciocutaneous flap to overcome the lack of local filling. Marked improvement of the gluteal and lumbar regions was noted after removal of the excess tissue, construction of an inferior fasciocutaneous flap, and use of skin traction. In addition, rotation of the flap and its attachment to the gluteal muscle markedly improved the patient's posterior contour and postoperative comfort. With minimal morbidity, excess skin was removed and the gluteal region was concomitantly increased using an autologous flap that is neglected in many techniques; this resulted in an improved contour and a discreet scar that could be hidden by the patient's underwear.

ABSTRACT

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.


As lesões do plexo lombar são incomuns e as descrições dos acessos cirúrgicos são derivadas de vias de acesso à coluna vertebral. MÉTODO: A via extraperitoneal anterolateral foi realizada em seis cadáveres para o acesso ao plexo lombar. Eventuais dificuldades na dissecção foram relatadas. RESULTADOS: Tal acesso permitiu a exposição dos elementos distais do plexo lombar, mas uma extensão cranial da incisão foi necessária para a exposição do nervo iliohipogástrico. Para a exposição dos nervos genitofemoral e obturador houve a necessidade da ligadura de vasos originados da artéria ilíaca comum em 2 casos. As raízes foram identificadas somente após dissecção e ligadura dos vasos lombares. CONCLUSÃO: O acesso anterolateral extraperitoneal permite uma exposição adequada dos nervos terminais do plexo lombar lateralmente ao músculo psoas maior. Uma extensão cranial da incisão pode ser necessária para exposição do nervo iliohipogástrico. A exposição das raízes implica em maior risco de lesão vascular.

ABSTRACT

Introdução: Os defeitos congênitos do tubo neural e tecidos associados são classificados como disrafismos espinhais, sendo a meningomielocele a forma mais grave. Objetivos: Avaliar a eficácia do retalho fasciocutâneo bipediculado bilateral no tratamento das meningomieloceles. Método: A técnica foi utilizada em 9 pacientes com diagnóstico de meningomielocele, no período de dezembro de 2006 a janeiro de 2009. Os pacientes foram submetidos à correção cirúrgica nas primeiras 36 horas de vida, com atuação conjunta das equipes de Neurocirurgia e de Cirurgia Plástica. Resultados: Observou-se que a principal localização do defeito foi a região lombossacra (77,78%), seguida da toracolombar (11,11%) e torácica (11,11%). A utilização do retalho fasciocutâneo bipediculado bilateral possibilitou o fechamento da lesão em todos os casos. O defeito apresentava, em média, 32,1 cm2. A única complicação observada nesta série foi a epiteliólise segmentar do retalho na linha média, observada em 1 (11,1%) paciente. Discussão: A escolha do retalho fasciocutâneo bipediculado bilateral utilizada nos casos apresentados deve-se à segurança em relação à vascularização, menor tempo cirúrgico quando comparado aos retalhos musculares, facilidadeda dissecção, aplicabilidade e baixos índices de complicação. Conclusão: O retalho fasciocutâneo bipediculado e bilateral é adequado para o tratamento das meningomieloceles.


Introduction: Neural tube defects and associated tissues are classified as spinal dysraphism, being the most severe one the meningomyelocele. Objectives: To evaluate the efficacy of the bilateral bipedicled fasciocutaneous flap in the meningomyeloceles treatment. Methods: Nine patients were operated on meningomyelocele from December 2006 to January 2009. The patients had a surgery correction performed in the first 36 hours of life, with the presence of Neurosurgery and Plastic Surgery teams. Results: The main location of the defect was in the lumbosacral region (77.78%), followed by the thoracolumbar (11.11%) and the thoracicone (11.11%). In all the cases, the bilateral bipedicled fasciocutaneous flap was performed to close the defect. Discussion: The bilateral bipedicled fasciocutaneous flap was chosen owing to the security regarding vascularization, the shorter surgical time compared to muscles flaps, dissection facility, applicability and low rate of complications. Conclusion: The bilateral bipedicled fasciocutaneous flap is an adequate treatment for meningomyelocele.

ABSTRACT

Different closure techniques are available after lumbosacral meningomylocele [MMC] resection for large defects reconstruction, but wound healing and tension-free closure in the midline remain major considerations. In this study we use Z plasty technique in closure of MMC defects>5 cm. Twenty newborns with large lumbosacral MMC were enrolled in this study. The mean age was 57.45 +/- 59.8 days. Complete healing of the skin occurred within two weeks in 14 patients [70%]. Superficial wound infection was seen in four patients [20%]. Necroses of the edges of the flap were showed in two patients [10%]. No mortality or complete wound dehiscence were observed in this study. Almost skin wounds healed without any major complications
