Abstract: Introduction: Changes in ligamentum flavum (LF) related to degeneration are secondary to either the aging process or mechanical instability. Previous studies have indicated that LF with aging shows elastic fiber loss and increased collagen content, loss of elasticity may cause LF to fold into the spinal canal, which may further narrow of the canal. Material and methods: A total of 67 patients operated with the surgical indications of lumbar spinal stenosis (LSS), lumbar disc herniation (LDH) and lumbar degenerative spondylolisthesis (LDS) were included. LF samples were obtained from patients who had LSS (39), LDH (22) and LDS (6). Specimens were examined with regard to chondroid metaplasia, calcification, fragmentation of collagen fibers, cystic degeneration, fibrillar appearence, and hypercellularity. Results: The most frequent histopathological changes were hyalinization and fragmentation of collagen fibers occur in 34%, neovascularization in 40.3% and irregular arrangement of elastic fibers is the most prevalent change with 56.7% of the total samples. There is a difference in the presence of certain changes in the LF according to the diagnosis, being statistically significant for fragmentation of collagen fibers (p = 0.045), cystic degeneration (p = 0.001), fibrillar appearance (p = 0.007) and hypercellularity (p = 0.005) all of these, being more prevalent in LDS group. LHD group presented fragmentation of collagen fibers in 45.5% (p = 0.045) and fibrillar appearance in 4.5% (p = 0.009). Conclusions: There is not evidence of cellular hyperthophy in the histhopatological analyses, thickening of the LF can be seen by bulking of LF followed by collapse of motion segment.

Resumen: Introducción: Los cambios en el ligamento flavum (LF) relacionados con la degeneración son secundarios al proceso de envejecimiento o a la inestabilidad mecánica. Estudios anteriores han indicado que LF con envejecimiento muestra pérdida de fibras elásticas y aumento del contenido de colágeno, la pérdida de elasticidad puede hacer que el LF se pliegue en el canal espinal, disminuyendo su espacio. Material y métodos: Se incluyeron 67 pacientes operados de estenosis lumbar espinal (LSS), hernia de disco lumbar (LDH) y espondilolistesis degenerativa (LDS). Se obtuvieron muestras de LF de pacientes que tenían LSS (39), LDH (22) y LDS (6). Se examinaron especímenes con respecto a metaplasia condroide, calcificación, fragmentación de fibras de colágeno, degeneración quística, apariencia fibrilar e hipercelularidad. Resultados: Los cambios histopatológicos más frecuentes fueron la hialinización y la fragmentación de las fibras de colágeno (34%), neovascularización en 40.3%, y la disposición irregular de las fibras elásticas es el cambio más frecuente con 56.7% del total de muestras. Existe una diferencia en la presencia de cambios en el LF, de acuerdo con el diagnóstico, siendo estadísticamente significativo para la fragmentación de las fibras de colágeno (p = 0.045), la degeneración quística (p = 0.001), la apariencia fibrilar (p = 0.007) y la hipercelularidad (p = 0.005) todos ellos, siendo más frecuentes en el grupo LDS. El grupo LHD presentó fragmentación de las fibras de colágeno en 45.5% (p = 0.045) y la apariencia fibrilar en 4.5% (p = 0.009). Conclusiones: No hay evidencia de hipertrofia celular en los análisis histopatológicos, el engrosamiento del LF se puede ver por abultamiento del mismo, seguido de colapso del segmento de movimiento.

SUMMARY OBJECTIVE: To investigate the efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of lumbar spinal stenosis (LSS) combined with osteoporosis. METHODS: Eighty patients with LSS combined with osteoporosis were divided into a control and PTED group, which received conventional transforaminal lumbar interbody fusion and PTED, respectively. The surgical indications, incision visual analogue scale (VAS), lumbar and leg pain VAS, lumbar Japanese Orthopaedic Association (JOA) and Oswestry disability index (ODI) scores, bone mineral density (BMD), and adverse reactions were observed. RESULTS: Compared with the control group, in the PTED group, the operation time, bleeding loss and hospitalization duration, incision VAS scores at postoperative 12, 24 and 48 h and lumbar and leg pain VAS and lumbar ODI scores on postoperative 6 months were significantly decreased (P < 0.01), and the lumbar JOA score on postoperative 6 months was significantly increased (P < 0.05). There was no significant difference in BMD between two groups (P > 0.05). Compared with the control group, in the PTED group, the total effective rate was significantly higher (P < 0.05), and the incidence of adverse reactions was significantly lower (P < 0.05). CONCLUSIONS: PTED is safe and effective in the treatment of LSS combined with osteoporosis.

RESUMO: OBJETIVO: Investigar a eficácia e segurança da discectomia endoscópica percutânea transforaminal (DEPT) no tratamento da estenose lombar (EL) combinada à osteoporose. MÉTODOS: Oitenta pacientes com EL combinada à osteoporose foram divididos entre um grupo de controle e um grupo de DEPT, que receberam tratamento convencional com fusão intersomática lombar transforaminal e DEPT, respectivamente. As indicações cirúrgicas, a escala analógica visual (VAS) da incisão e de dor lombar e nas pernas, os escores lombares de acordo com a Associação Ortopédica Japonesa (JOA) e o Oswestry Disability Index (ODI), a densidade mineral óssea (DMO) e possíveis reações adversas foram observados. RESULTADOS: Em comparação com o grupo de controle, no grupo de DEPT o tempo de operação, a perda de sangue e duração de internação, os escores VAS da incisão no pós-operatório após 12, 24 e 48 h, o VAS para dor lombar e nas pernas e os escores ODI lombares após 6 meses de pós-operatório foram significativamente menores (P < 0,01); já o escore JOA lombar após 6 meses de pós-operatório foi significativamente maior (P < 0,05). Não houve diferença significativa na densidade mineral óssea entre os dois grupos (P > 0,05). Em comparação com o grupo de controle, o grupo de DEPT teve uma taxa efetiva total significativamente maior (P < 0,05), e a incidência de reações adversas foi significativamente menor (P < 0,05). CONCLUSÕES: A discectomia endoscópica percutânea transforaminal é segura e eficaz no tratamento de EL combinada à osteoporose.

ABSTRACT Objective: The objective of this study was to present an analysis of progression of the quality of life and pain in patients undergoing surgical treatment of LSS and the potential correlations between individual factors and the clinical outcome observed. Methods: We studied 111 patients undergoing surgical treatment of LSS from January 2009 to December 2011 using the functional capacity (ODI) and pain (VAS) questionnaires. The preoperative data were compared statistically with the results obtained during the postoperative follow-up at one month, six months, one year, and two years. Results: The population consisted of 60 men and 51 women. The mean age was 61.16 years at the time of surgery, 33.33% were 60 years or older. When the questionnaires were applied, we found improvement in the progressive disability assessment with a mean drop of 23.65 ODI points after 6 months of the surgical treatment and 27.47 at the end of one year of surgery compared to preoperative for this scale. There was a decline of 3.84 points (mean) in the VAS at first postoperative month. Conclusion: Surgical treatment of LSS presented favorable postoperative evolution in a 2-year follow-up regarding pain and quality of life through VAS and ODI. Level of Evidence IV; Case series.

ABSTRACT Objective: The objective of this study was to determine the factors associated with the persistence of pain in patients operated on for lumbar stenosis. Method: One hundred and fifty-three patients were studied, divided into two groups: 1) Patients with persistent pain in varying degrees, 2) Patients without pain. Age, sex, affected levels, comorbidities, surgical risk, and type of surgical procedure were evaluated. Results: There were 108 patients in the group with pain and 45 in the group without pain. In the group with pain, there were 28 patients with diabetes mellitus, 31 smokers, and 28 alcohol-dependent patients, with a significant difference of p = 0.001 and an RR = 1.1. A simple widening procedure was performed in 48 patients in the group with pain and 12 patients in the group without pain, with RR = 0.8, and widening plus instrumentation was performed in 7 patients in both the with and without pain groups. Conclusion: The indication of a surgical procedure in patients with spinal stenosis must take many factors into account in addition to clinical factors and the segments affected, since these factors impact patient prognosis. In the multivariate analysis, the variable most closely associated with persistent pain was the procedure performed. Level of Evidence III; Case-control study.g

Resumen: Antecedentes: Diversos autores y publicaciones se han enfocado en comparar la evolución clínica de la cirugía descompresiva de las raíces, ya sea con o sin fusión, para el tratamiento del canal lumbar estrecho degenerativo. Sin embargo, no existen muchos reportes que analicen la evolución clínica tras la cirugía descompresiva de una sola raíz nerviosa (la más sintomática) contra la descompresión de todas las raíces de un segmento. El presente estudio pretende comparar la evolución clínica de la liberación radicular lumbar de la raíz más sintomática con respecto a la liberación de múltiples raíces lumbares para el alivio del dolor neuropático en el canal lumbar estrecho degenerativo. Material y métodos: Se realizó un estudio prospectivo observacional, descriptivo, longitudinal con 38 pacientes divididos en dos grupos de 19 casos a quienes se les practicó recalibraje de una sola raíz o de múltiples raíces de un segmento; se obtuvieron porcentajes, t de Student y coeficiente de correlación de Pearson. Resultados: En el grupo A, se evidenció una disminución de 46.63 puntos en la escala de Oswestry, lo que traduce una mejoría del dolor de 66.73%. En el grupo B, en cambio, se observó una disminución promedio de 34.54 puntos en la escala de Oswestry, equivalente al 47.23%, con una t de Student donde p = 0.11 y el coeficiente de correlación de Pearson, 0.08. Conclusiones: No se encontraron diferencias estadísticamente significativas entre ambos grupos de estudio.

Abstract: Background: Several authors and publications have focused on comparing the clinical course of nerve root decompressive surgery, with or without fusion, to treat degenerative lumbar stenosis. However, there are not many reports analyzing the clinical course after decompressive surgery of a single nerve root (the most symptomatic one) comparing it with decompression of all the roots in a segment. This study intends to compare the clinical course after decompressing the most symptomatic lumbar nerve root with the release of multiple lumbar nerve roots to relieve neuropathic pain resulting from degenerative lumbar stenosis. Material and methods: A prospective, observational, descriptive longitudinal study was performed. A total of 38 patients were divided into two groups that included each 19 cases. Patients underwent recalibration of either a single nerve root or multiple nerve roots of a segment. Percentages were calculated as well as the Student t test and the Pearson correlation. Results: In group A, a decrease of 46.63 points was seen in the Oswestry scale, representing a 66.73% improvement in pain. In group B, in turn, a mean decrease of 34.54 points was seen in the Oswestry scale, equivalent to a 47.23% improvement in pain, with a Student t in which p = 0.11 and a Pearson correlation coefficient of 0.08. Conclusions: No statistically significant differences were found between both study groups.

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 spondylolisthesis on lumbar lordosis after an intraoperative prone position. METHODS: Sixty-seven patients, who underwent spinal fusion at the Department of Orthopaedic Surgery of Gwangmyeong Sungae Hospital between May 2007 and February 2012, were included in this study. The study compared lumbar lordosis on preoperative upright, intraoperative prone and postoperative upright lateral X-rays between the simple stenosis (SS) group and spondylolisthesis group. The average age of patients was 67.86 years old. The average preoperative lordosis was 43.5degrees (+/- 14.9degrees), average intraoperative lordosis was 48.8degrees (+/- 13.2degrees), average postoperative lordosis was 46.5degrees (+/- 16.1degrees) and the average change on the frame was 5.3degrees (+/- 10.6degrees). RESULTS: Among all patients, 24 patients were diagnosed with simple spinal stenosis, 43 patients with spondylolisthesis (29 degenerative spondylolisthesis and 14 isthmic spondylolisthesis). Between the SS group and spondylolisthesis group, preoperative lordosis, intraoperative lordosis and postoperative lordosis were significantly larger in the spondylolisthesis group. The ratio of patients with increased lordosis on the OSI frame compared to preoperative lordosis was significantly higher in the spondylolisthesis group. The risk of increased lordosis on frame was significantly higher in the spondylolisthesis group (odds ratio, 3.325; 95% confidence interval, 1.101 to 10.039; p = 0.033). CONCLUSIONS: Intraoperative lumbar lordosis on the OSI frame with a prone position was larger in the SS patients than the spondylolisthesis patients, which also produced a larger postoperative lordosis angle after posterior spinal fusion surgery. An increase in lumbar lordosis on the OSI frame should be considered during posterior spinal fusion surgery, especially in spondylolisthesis patients.

With the aging of the world population, the treatment of stenosis of the lumbar canal has become an important issue in addressing degenerative diseases of the spine. The prevalence of this disease tends to increase as the number of surgeries and the impact on health care costs. This paper aims to describe in detail the technique of unilateral laminotomy for bilateral microdecompression (ULBM) of stenosis of the lumbar canal (LSC) and current clinical results, including their advantages, disadvantages and common complications, based on the available literature. Important studies have shown evidence that surgical treatment for LSC is more effective than the conservative, but without evaluating ULBM. Several studies on ULBM have been conducted since the 90s, showing the results of this technique, however, most of these are case series, retrospective studies or cohorts without proper control group or with weak statistical analysis to prove some evidence. A double-blind randomized clinical trial was found, but with short follow-up. We conclude that studies are needed with more solid evidence to prove the effectiveness of ULBM despite the clinical results being similar to those of classical surgery found in the literature.

Com o envelhecimento da população mundial, o tratamento da estenose do canal lombar tornou-se uma questão importante na abordagem das doenças degenerativas da coluna. A prevalência dessa patologia tende a aumentar, assim como o número de cirurgias e o impacto sobre os custos da saúde. Este trabalho tem como objetivo descrever com detalhes a técnica de laminotomia unilateral para microdescompressão bilateral (LUMB) de estenose do canal lombar (ECL) e os resultados clínicos atuais, incluindo suas vantagens, desvantagens e complicações comuns, com base na literatura disponível. Estudos importantes demonstraram evidências de que o tratamento cirúrgico da ECL é mais eficaz do que o conservador, porém sem avaliar a LUMB. Vários trabalhos sobre LUMB foram realizados desde a década de 90, mostrando os resultados dessa técnica, porém, a maioria consiste em séries de casos, estudos retrospectivos, ou coortes sem grupo controle adequado ou com análises estatísticas fracas para provar alguma evidência. Foi encontrado um ensaio clínico duplo cego randomizado, porém com período curto de acompanhamento. Conclui-se que são necessários trabalhos com evidências mais sólidas para comprovar a eficácia da LUMB, apesar de seus resultados clínicos serem semelhantes aos da cirurgia clássica encontrados na literatura especializada.

Se encontró un ensayo clínico aleatorizado y doble ciego, pero con seguimiento corto. Se concluye que son necesarios trabajos que presenten evidencia más sólida para demostrar la eficacia de la LUMB, a pesar de sus resultados clínicos muy semejantes a los resultados de la cirugía clásica encontrados en la literatura especializada.

OBJECTIVES: To compare the clinical outcomes between patients with degenerative lumbar stenosis who were treated by decompression with those awaiting the same kind of treatment for the disease. METHODS: Retrospective study which divided patients with degenerative lumbar stenosis with surgical indication in 2 groups, operated and awaiting the procedure. The Oswestry Disability Index (ODI) questionnaire, visual analog scale and SF36 were applied. RESULTS: Twelve operated patients and 18 awaiting the procedure were included. The average age of those operated was 59 years (43-70), and 55 (37-82) (p=0.3) for those awaiting surgery. The operated group had a mean ODI of 38.67 against 59.72 (p<0.05) in the non-operated group. The pain analog scale had lumbar result of 5.33 and pain radiating to the lower limbs of 3.83 in operated patients, against 6.78 (p>0.05) and 7.22 (p<0.05) in the awaiting surgery patients, respectively. As for the SF36 scale, functional capacity, limitations due to physical aspects and pain had an average score of 36.25, 19.58 and 21.67 in the operated group against 35.94, 27.50 and 32.61 in the awaiting group (p>0.05), respectively. CONCLUSION: The operated patients showed improvement of referred pain in the lower limbs (leg VAS) and improved function (Oswestry), however showed no significant change in quality of life according to SF36 scale and low back pain (lumbar VAS) were found.

OBJETIVOS: Comparar os resultados clínicos entre os pacientes com estenose lombar degenerativa que foram tratados por descompressão com aqueles que aguardam o mesmo tipo de tratamento para a doença. MÉTODOS: Estudo retrospectivo que dividiu os pacientes com estenose lombar degenerativa com indicação cirúrgica em dois grupos, operados e que aguardam o procedimento. Foram aplicados o questionário Oswestry Disability Index (ODI), Escala Visual Analógica e SF36. RESULTADOS: Foram incluídos 12 pacientes operados e 18 pacientes que aguardam o procedimento. A média de idade dos operados foi 59 anos (43-70) e a dos que aguardam a cirurgia foi 55 (37-82) (p = 0,3). O grupo operado teve ODI médio de 38,67 contra 59,72 dos que aguardavam (p < 0,05). A escala analógica da dor teve resultado lombar de 5,33 e de dor irradiada para os membros inferiores de 3,83 nos operados, contra 6,78 (p > 0,05) e 7,22 (p < 0,05), respectivamente, no grupo que aguarda cirurgia. Quanto à escala SF36, capacidade funcional, limitação por aspectos físicos e dor tiveram resultado médio de 36,25, 19,58 e 21,67 nos pacientes operados contra 35,94, 27,50 e 32,61, respectivamente, nos ainda não operados (p > 0,05). CONCLUSÃO: Os pacientes operados apresentaram melhora da dor reflexa nos membros inferiores (VAS Perna) e melhora na função (Oswestry), porém não demonstraram alteração significativa da qualidade de vida segundo a escala SF36 e dor lombar (VAS Lombar).

Los pacientes mayores de 80 años presentan características y comorbilidades que incrementan los riesgos perioperatorios y pueden ocasionar malos resultados. OBJETIVO: mostrar resultados en el tratamiento quirúrgico, mediante descompresión, de los pacientes mayores de 80 años con diagnóstico de estenosis lumbar degenerativa. MÉTODOS: estudio de intervención longitudinal prospectivo con 13 pacientes mayores de 80 años de edad, siete hombres y seis mujeres, diagnosticados e intervenidos por estenosis lumbar degenerativa entre el 1ro. de enero de 2005 y el 31 de octubre de 2011, en el Centro de Investigaciones en Longevidad, Envejecimiento y Salud, y evaluados dos años después. RESULTADOS: predominó la afectación de cuatro o más espacios intervertebrales, con más de dos años de padecer fundamentalmente del síntoma de claudicación de origen neurógeno, las comorbilidades de causas cardiovasculares y ocurrieron cinco complicaciones perioperatorias. La disminución del dolor y del nivel de discapacidad fue significativa, con predominio de resultados bueno y regular. CONCLUSIONES: el tratamiento quirúrgico de la estenosis lumbar degenerativa, en pacientes mayores de 80 años de edad, según nuestros resultados, produce efectos beneficiosos, con disminución de dolor y discapacidad y baja ocurrencia de complicaciones.

INTRODUCTION: the diagnosis of degenerative lumbar stenosis has increased in recent years and it represents an important part of the daily activities of spinal surgeons. Patients older than 80 have characteristics and comorbidities that increase the perioperative risk causing bad results. OBJECTIVe: show results in the surgical treatment by decompression of patients older than 80 years diagnosed with degenerative lumbar stenosis. METHODS: a prospective longitudinal intervention study was conducted in 13 patients older than 80 years of age, seven men and six women diagnosed and treated for degenerative lumbar stenosis, from January 1, 2005 to October 31, 2011, at the Center for Research in Longevity, Aging and Health, and they were evaluated two years later. RESULTS: predominant involvement of four or more intervertebral spaces, more than two years of suffering primarily symptom of neurogenic claudication, comorbidities and cardiovascular causes occurred five perioperative complications. Reducing pain and disability was significant, with a predominance of good and fair results. CONCLUSIONS: surgical treatment of degenerative lumbar stenosis, in patients older than 80 years, according to our results, produces beneficial effects, with reduced pain and disability and low occurrence of complications.

Introducción: Se han desarrollado una variedad de sistemas para fijar y artrodesar la columna cervical con las ventajas de reducir del riesgo de seudoartrosis, extrusión y colapso del injerto, así como una mayor precisión en la alineación sagital, por tal motivo requerimos comparar resultados de placa-injerto, caja-placa y caja-PEEK, en pacientes con conducto cervical estrecho. Material y métodos: Estudio prospectivo, de intervención y comparativo, formando tres grupos: grupo I, artrodesis con placa-injerto, grupo II, caja-placa, grupo III, caja-PEEK. La evaluación funcional pre- y postoperatoria con escala de discapacidad cervical y escala visual análoga (EVA) de dolor y radiografías columna cervical. Se analizaron los resultados con pruebas no paramétricas de rangos con signo de Wilcoxon y Kruskal Wallis para comparación entre más de dos grupos. Con nivel de significancia de 0.05. Resultados: Muestra de 37 pacientes para el grupo I con n = 12, con 22 niveles; grupo II con: n = 11, con 19 niveles; grupo III con: n = 14 con 25 niveles. La mayoría de pacientes entre la sexta y octava década de la vida. Al año de postoperados el índice de discapacidad cervical y mejoría del dolor con EVA mostraron mejoría con diferencia estadística en los tres grupos (p = 0.001). Sin embargo, las mediciones radiográficas al año de seguimiento mostraron una mejoría significativa de la lordosis segmentaria (p = 0.02) sólo en pacientes operados con placa-injerto. Conclusiones: El uso de la placa injerto ofrece mejores resultados clínicos y radiográficos en comparación con la caja-placa y caja-PEEK al año de seguimiento.

Introduction: A variety of systems have been developed to fix and perform arthrodesis of the cervical spine, with the advantages of reducing the risk of pseudoarthrosis, extrusion and graft collapse and achieving a more precise sagittal alignment. We therefore need to compare the results of the following approaches to patients with cervical stenosis: plate-graft, cage-plate and PEEK cage. Material and methods: Prospective, interventional, comparative trial involving three groups: group I, arthrodesis with plate-graft; group II, cage-plate, and group III, PEEK cage. The pre- and postoperative assessments included the cervical disability scale, the pain visual analog scale (VAS), and cervical spine X-rays. The results were analyzed with non-parametric tests such as the Wilcoxon sign test and the Kruskal-Wallis test for the comparison of more than two groups. Significance level was 0.05. Results: The sample included a total of 37 patients: n = 12 in group I, with 22 levels; n = 11 in group II, with 19 levels, and n = 14 in group III, with 25 levels. Patient age ranged between 60 and 80. One year after surgery there was an improvement in cervical disability and the pain VAS score, with a statistically significant difference among the three groups (p = 0.001). However, radiographic measurements at that time showed a significant improvement in segmental lordosis (p = 0.02) only in plate-graft patients. Conclusions: The plate-graft approach provides better clinical and radiographic results compared to the cage-plate and PEEK cage techniques, at the one-year follow-up.

BACKGROUND: To describe and assess clinical outcomes of the semi-circumferential decompression technique for microsurgical en-bloc total ligamentum flavectomy with preservation of the facet joint to treat the patients who have a lumbar spinal stenosis with degenerative spondylolisthesis. METHODS: We retrospectively analyzed the clinical and radiologic outcomes of 19 patients who have a spinal stenosis with Meyerding grade I degenerative spondylolisthesis. They were treated using the "semi-circumferential decompression" method. We evaluated improvements in back and radiating pain using a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). We also evaluated occurrence of spinal instability on radiological exam using percentage slip and slip angle. RESULTS: The mean VAS score for back pain decreased significantly from 6.3 to 4.3, although some patients had residual back pain. The mean VAS for radiating pain decreased significantly from 8.3 to 2.5. The ODI score improved significantly from 25.3 preoperatively to 10.8 postoperatively. No significant change in percentage slip was observed (10% preoperatively vs. 12.2% at the last follow-up). The dynamic percentage slip (gap in percentage slip between flexion and extension X-ray exams) did not change significantly (5.2% vs. 5.8%). Slip angle and dynamic slip angle did not change (3.2° and 8.2° vs. 3.6° and 9.2°, respectively). CONCLUSIONS: The results suggested that semi-circumferential decompression is a clinically recommendable procedure that can improve pain. This procedure does not cause spinal instability when treating patients who have a spinal stenosis with degenerative spondylolisthesis.

Development of anesthesiology and improvement of surgical instruments enabled aggressive surgical treatment even in elderly patients, who require more active physical activities than they were in the past. However, there are controversies about the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. The purpose of this study is to review the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. MEDLINE search on English-language articles was performed. There were 39685 articles from 1967 to 2013 regarding spinal disease, among which 70 dealt with geriatric lumbar surgery. Eighteen out of 70 articles dealt with geriatric lumbar surgery under the diagnosis of spinal stenosis or spondylolisthesis. One was non-randomized prospective, and other seventeen reports were retrospective. One non-randomized prospective and twelve out of seventeen retrospective studies showed that old ages did not affect the clinical outcomes. One non-randomized prospective and ten of seventeen retrospective studies elucidated postoperative complications: some reports showed that postoperative complications increased in elderly patients, whereas the other reports showed that they did not increase. Nevertheless, most complications were minor. There were two retrospective studies regarding the mortality. Mortality which was unrelated to surgical procedure increased, but surgical procedure-related mortality did not increase. Surgery as a treatment option in the elderly patients with the spinal stenosis or spondylolisthesis may be reasonable. However, there is insufficient evidence to make strong recommendations regarding spinal surgery for geriatric patients with spinal stenosis and spondylolisthesis.

Objectives: To study the characteristics of patients who underwent surgical treatment of degenerative spinal stenosis in the last 10 years (2000â€"2010) at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto (USP-HCFMR) and correlate the postoperative complications and preoperative comorbidities found in the study population. Methods: Retrospective review of medical records and radiographs of patients with degenerative lumbar stenosis treated surgically. Descriptive analysis of data was done with SAS 9.0. Results: 92 patients were included, 47 (51.08%) males and 45 (48.91%) females, with ages ranging from 32 to 86 years (mean age of 64.27 years). The most prevalent comorbidities were hypertension (47.82%) and diabetes mellitus (25%). Twenty-three patients (25%) had two or more comorbidities. Postoperative infection was the most common complication found in 12 cases (13%). Patients with only one preoperative comorbidity showed similar complication rates compared to the population without comorbidities. However, patients with two or more comorbid conditions had a higher incidence of postoperative complications (p<0.001). Conclusions: Comorbidities negatively influenced the outcome of surgical treatment of degenerative lumbar stenosis with higher rates of postoperative complications. .

OBJECTIVE: To evaluate the expectations of patients awaiting surgical treatment of lumbar canal stenosis and the association of Health-Related Quality of Life (HRQoL) with symptoms of anxiety and depression. METHODS: The sample included 49 patients from a university hospital. HRQoL was assessed by the Oswestry Disability Index (ODI) and 36-item Medical Outcomes Survey Short Form (SF-36) and symptoms of anxiety and depression by the Hospital Anxiety and Depression Scale (HADS). Expectations were investigated by means of questions used in international studies. Data were analyzed descriptively and by Student's t test. RESULTS: The mean time of disease progression was 34.5 months, the mean age was 58.8 years and 55.1% of the patients were women. Most patients had the expectation of improving with surgical treatment and 46.9% expected to be "much better" with regard to leg pain, walking ability, independence in activities and mental well being. The scores of anxiety and depression were respectively, 34.7% and 12.2%. We observed statistically significant differences between the groups with and without anxiety in the domains: General Health, Mental Health, and Vitality. Between the groups with and without depression there were statistically significant differences in the General Health and Mental Health domains. CONCLUSION: Patients showed great expectation to surgical treatment and the symptoms of anxiety and depression were related to some domains of HRQoL. Thus, the study contributes to broaden our knowledge and we can therefore guide the patients as to their expectations with respect to the real possibilities arising from surgery. .
