ABSTRACT

El queratoquiste es una lesión odontogénica benigna de comportamiento agresivo, que deriva probablemente de la lámina dental. Se localiza frecuentemente en la parte posterior del hueso mandibular en la zona del tercer molar, ángulo mandibular y puede progresar hacia la rama y el cuerpo, presentando una asociación directa con órganos dentales retenidos. Existe una amplia variedad de técnicas para el tratamiento de esta lesión, como pueden ser descompresión, marsupialización, enucleación y la resección en bloque, así como también la combinación de estas con métodos coadyuvantes. El interés en esta lesión radica por su elevado índice de recidiva que se estima en un 20-30% en la población en general, sin embargo, en la actualidad se ha optado por el uso de tratamientos conservadores como la marsupialización y la descompresión que han demostrado una mayor efectividad y menor recidiva. Es por esto que tras el tratamiento de las lesiones es importante dar un seguimiento a largo plazo. El objetivo de la publicación es presentar el reporte de un caso clínico de un paciente masculino de 21 años con un diagnóstico de queratoquiste odontogénico tratado con una técnica de descompresión durante cinco meses para su posterior enucleación quirúrgica.Se ha comprobado que el tratamiento de descompresión seguido de enucleación y acompañado de métodos coadyuvantes resulta un manejo terapéutico adecuado para los queratoquistes por demostrar su menor tasa de recidiva y su comportamiento noble con estructuras vitales vecinas. Sin embargo, en todos los casos se debe realizar un seguimiento periódico para prevenir la recurrencia de la lesión.


Introduction: Keratocyst is a benign odontogenic lesion with aggressive behavior, probably derived from the dental lamina. It is frequently located in the posterior part of the mandibular bone in the area of the third molar, mandibular angle and can progress towards the ramus and the body, presenting a direct association with retained dental organs. There is a wide variety of techniques for the treatment of this lesion, such as decompression, marsupialization, enucleation, and en bloc resection, as well as the combination of these with adjuvant methods. The interest in this lesion stems from its high recurrence rate, which is estimated to be 20-30% in the general population, however, at present the use of conservative treatments such as marsupialization and decompression has been chosen. demonstrated greater effectiveness and less recurrence. This is why after treating the lesions it is important to give a long-term follow-up.The objective of the publication is to present the report of a clinical case of a 21-year-old male patient with a diagnosis of odontogenic keratocyst treated with a decompression technique for five months for subsequent surgical enucleation.Conclusion: It has been proven that decompression treatment followed by enucleation and accompanied by adjuvant methods is an adequate therapeutic management for keratocysts as it demonstrates its lower rate of recurrence and its noble behavior with neighboring vital structures. However, in all cases, regular monitoring should be carried out to prevent recurrence of the lesion

As conclusões. A OAT foi associada principalmente ao hipertiroidismo, sendo mais comum em pacientes do sexo feminino entre os 40 e os 59 anos; mais de 50% dos pacientes necessitaram do uso de hipotensivos oculares. Da mesma forma, a gestão cirúrgica foi realizada em mais de 50% dos pacientes, sendo a descompressão orbital a intervenção mais frequente.


ABSTRACT Objective. To know the demographic and clinical characteristics of Thyroid Associated Orbitopathy (TAO), as well as the requirement rate of orbital surgery in patients of the Orbit Service in the National Medical Center of the West, IMSS. Methods. Observational, cross-cutting, descriptive and retrospective study carried out analyzing the records of patients diagnosed with TAO and treated at a third-level care center from January 2005 to July 2016. Results. A total of 236 orbits of 118 patients were valued, with an average age of 47.3 ± 13.2 years, 74.6% were female and 25.4% male. 4.2% of patients were treated with hypothyroidism, 94.1% with hyperthyroidism and 1.7% with diffuse toxic goiter. 44.9% of patients studied had eye movement restriction,10.2% exposure keratopathy and 51.7% intraocular hypertension. 34.7% of patients valued in the service required orbital decompression, 16.1% palpebral surgery and 8.5% strabism correction. In the conservative management of these patients 48.3% required the use of topical eye lubricants, while 52.5% required the use of eye hypotensives in variable numbers. Conclusions. TAO was mainly associated with hyperthyroidism, being more common in female patients between the age of 40 and 59; more than 50% of patients required the use of eye hypotensives. Likewise, surgical management was performed in more than 50% of patients, with orbital decompression being the most frequent intervention.

ABSTRACT

Los quistes odontogénicos se dividen en dos grupos principales de acuerdo a la patogénesis de la entidad. Uno de esos grupos incluye a los quistes radiculares de origen inflamatorio. Nuestra situación es una paciente de sexo femenino que a causa de un molar superior con tratamiento endodóntico la patología quística invadió la cavidad sinusal comprometiendo las estructuras vecinas y al realizar la exodoncia se generó una comunicación bucosinusal con infección de esa entidad patológica. El diagnostico de certeza se confirmó a través de la biopsia previa, y se la intervino bajo anestesia general para la extirpación total de la patología quística (AU)

ABSTRACT

OBJECTIVE@#To explore the diagnosis, treatment, cause and prevention of nerve compression by bone fragment after lumbar spine surgery.@*METHODS@#The clinical data of 23 patients with nerve compression by bone fragment after lumbar spine surgery from February 2012 to March 2019 were collected retrospectively, including 9 males and 14 females, aged 42 to 81 years with an average of (62.60±5.70) years. The surgical methods included lumbar interbody fusion in 20 cases and spinal endoscopy in 3 cases. All 23 patients experienced radiating pain on the decompression side or the contralateral limb after operation. The time of occurrence was from immediately after operation to 2 weeks after operation, with an average of (3.2±1.7) days. All patients underwent postoperative examination of lumbar spine CT or MRI to confirm residual ectopic bone fragments, and at the same time, bilateral lower extremity color Doppler ultrasound excluded thrombosis. Sources of ectopic bone fragments:14 cases of residual bone fragments caused by intervertebral fusion bone graft loss or fenestration fusion, 6 cases of fractured upper articular process head, and 3 cases of upper articular process bone remaining during spinal endoscopic surgery.@*RESULTS@#The patient's hospital stay was 10 to 37 (23.4±6.2) days. All patients were followed up for 6 to 25 (13.6±3.4) months. Three patients underwent posterior open nerve root exploration for removing bone fragments on the same day or the second day after surgery, and the symptoms were relieved. Twenty patients underwent conservative treatment firstly, and 13 patients were discharged after pain relieved by conservative treatment, 7 patients failed conservative treatment, the 2 cases of failed 7 cases had undergone nerve root block surgery during conservative treatment. Two patients underwent spinal endoscopy nerve root exploration and bone mass removal, and five patients underwent posterior open nerve root exploration and bone fragmentation removal. All postoperative pain symptoms were relieved. Preoperative CT, MRI and intraoperative bone fragment removal confirmed the shape and location of the bone fragments. The most likely source of bone fragments was the loss of intervertebral fusion bone grafts or residual bone fragments resulting from fenestration fusion (14 cases), fractured upper articular process head (6 cases), and upper articular process bones remaining in endoscopic surgery (3 cases). According to the Macnab criteria in evaluating clinical outcome, 20 cases got excellent results and 3 good.@*CONCLUSION@#After the lumbar spine surgery, the nerve compression by bone fragments is treated with appropriate treatments, and good clinical results can be obtained. Timely removal of residual bone fragments during operation and careful exploration of nerve roots before closing incision can avoid such complications.

ABSTRACT

OBJECTIVE@#To evaluate clinical effect of unilateral approach and bilateral decompression via large channel endoscopic system for the treatment of lumbar spinal stenosis.@*METHODS@#The clinical data of 32 patients with lumbar spinal tenosis treated by unilateral approach and bilateral decompression via large channel endoscopy from February 2018 to February 2019 were retrospectively analyzed. There were 18 males and 14 females, aged 65 to 84 years old with an average of (70.6± 8.4) years. The course of disease was from 1 to 12 years. All 32 cases were accompanied by numbness or pain in the lower limbs, of which 28 cases were accompanied by intermittent claudication. Narrow segments were L@*RESULTS@#All the patients were followed up for 12-24 (17.68±2.43) months and all operations were successfully completed with the operation time of 70-160(85.64±11.94) min. Spinal dural tear occurred in 1 case during the operation, and sensory disturbance in the other side of lower limb in a short period of time occurred in 2 cases, all improved after corresponding treatment. Postoperative imaging showed that the spinal canal was significantly enlarged and the nerve root was fully released. Before operation and 3 days, 3 months, 1 year after operation, VAS scores of low back pain were 4.62 ±1.41, 2.73 ±1.35, 1.21 ±1.17, 1.11 ±0.34, respectively;VAS scores of leg pain were 6.83 ± 1.71, 3.10±1.50, 1.08±0.19, 0.89±0.24, respectively. VAS scores of low back pain and leg pain each time point after operation were obvious improved (@*CONCLUSION@#It is a safe and effective way to treat lumbar spinal stenosis with unilateral approach and bilateral decompression via large channel endoscopic system. It has the advantages of sufficient decompression, less trauma, fast recovery, high safety and low incidence of postoperative complications. It can minimize the damage to the stable structure of the lumbar spine and is an ideal minimally invasive operation for the treatment of lumbar spinal stenosis.

ABSTRACT

OBJECTIVE@#To investigate the efficacy of self-made arthroscopic single channel in the treatment of carpal tunnel syndrome.@*METHODS@#Sixty patients with primary carpal tunnel syndrome treated from January 2014 to December 2019 were divided into arthroscopic group and traditional open operation group. There were 30 cases in arthroscopic group, including 12 males and 18 females, aged (47.5±4.5) years and the course of disease was (6.6±4.2) months. There were 30 cases in the traditional operation group, including 10 males and 20 females, aged (48.5±3.5) years, and the course of disease was (5.6±4.4) months. Both groups were unilateral. According to the anatomy of wrist joint and the characteristics of transverse carpal ligament and arthroscopy, the instruments including cannula, inner heart and hook knife were designed. The patients in two groups were treated with decompression of transverse carpal ligament using arthroscopy combined with self-made instruments and traditional open sergery. The incision length, operation time, intraoperative bleeding, hospitalization cost, hospitalization time and recovery time of the two groups were observed and compared. Boston Carpal Tunnel Questionnaire (BCTQ) score was used to evaluate the clinical efficacy of arthroscopy combined with self made instruments in the treatment of carpal tunnel syndrome.@*RESULTS@#Compared with the traditional group, the arthroscopic group had significant advantages in incision length, operation time, intraoperative bleeding and hospital stay, but the total cost of hospitalization was increased. The Boston score was significantly higher in the arthroscopic group than that in the traditional group at 1 month after operation, but not at 3 and 6 months after operation.@*CONCLUSION@#Arthroscopy combined with self-made instruments in the treatment of carpal tunnel syndrome is more reliable, minimally invasive and simplified than open surgery, but the patients should be clearly diagnosed and appropriately selected before operation to achieve satisfactory clinical effect.

ABSTRACT

Spinal disease is an important cause of cervical discomfort, low back pain, radiating pain in the limbs, and neurogenic intermittent claudication, and its incidence is increasing annually. From the etiological viewpoint, these symptoms are directly caused by the compression of the spinal cord, nerve roots, and blood vessels and are most effectively treated with surgery. Spinal surgeries are primarily performed using two different techniques: spinal canal decompression and internal fixation. In the past, tactile sensation was the primary method used by surgeons to understand the state of the tissue within the operating area. However, this method has several disadvantages because of its subjectivity. Therefore, it has become the focus of spinal surgery research so as to strengthen the objectivity of tissue state recognition, improve the accuracy of safe area location, and avoid surgical injury to tissues. Aside from traditional imaging methods, surgical sensing techniques based on force, bioelectrical impedance, and other methods have been gradually developed and tested in the clinical setting. This article reviews the progress of different tissue state recognition methods in spinal surgery and summarizes their advantages and disadvantages.

ABSTRACT

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

ABSTRACT

Introducción: La enfermedad de Parkinson afecta principalmente a personas >65 años. El cuadro degenerativo lumbar en el contexto de un canal estrecho sumado a la alteración neuromuscular y la mala calidad ósea, favorece al desequilibrio sagital y coronal. Los pacientes que necesitan cirugía tienen altas tasas de revisión y reoperación con técnicas instrumentadas y no ins-trumentadas. El objetivo de este estudio fue evaluar la técnica quirúrgica de descompresión mínimamente invasiva en pacientes con enfermedad de Parkinson y dolor radicular o claudicación neurogénica en los miembros inferiores. materiales y métodos: Se evaluó a pacientes con diagnóstico de canal lumbar estrecho y enfermedad de Parkinson tratados quirúrgicamente. El procedimiento se indicó por síntomas de canal estrecho o estenosis foraminal de causa degenerativa. Todos fueron tratados con una cirugía descompresiva a través de una hemilaminectomía mínimamente invasiva mediante retracción tubular y asistencia con microscopia. Resultados: De enero de 2015 a diciembre de 2017, se trató a 6 pacientes con enfermedad de Parkinson y canal lumbar estrecho. Se descomprimieron 12 niveles en total, todos estuvieron internados <24 h. No se necesitaron transfusiones, no hubo complicaciones asociadas, el tiempo promedio de cirugía fue de 120 minutos. El seguimiento mínimo fue de 12 meses, los síntomas no reaparecieron. Conclusiones: La elevada tasa de complicaciones en pacientes operados con enfermedad de Parkinson y la disminución de las complicaciones en este estudio sugieren que la cirugía mínimamente invasiva de columna lumbar debería ser una alternativa quirúrgica en estos pacientes. Nivel de Evidencia: IV


Introduction: Parkinson's disease mainly affects patients aged 65 and older. The degenerative condition at the lumbar spine in the context of a narrow canal added to the neuromuscular disorder and poor bone quality favors sagittal and coronal imbalance. Patients who need surgery have high rates of revision and reoperation with instrumented and non-instrumented techniques. The objective of this study was to evaluate the minimally invasive surgical decompression technique in patients with Parkinson's disease and radicular pain or neurogenic claudication in the lower limbs. Materials and Methods: Surgically treated patients with a diagnosis of lumbar spinal stenosis and Parkinson's disease were evaluated. The indication for the procedure was due to symptoms of the lumbar or foraminal stenosis of degenerative cause. All the patients were treated with decompressive surgery through a minimally invasive hemilaminectomy using tubular retraction and assistance with microscopy. Results: From January 2015 to December 2017, 6 patients with Parkinson's disease and lumbar spinal stenosis were treated. A total of 12 segments were decompressed, all patients were hospitalized for less than 24 hours. They did not require a transfusion nor suffered associated complications, with an average surgery time of 120 minutes. All with a minimum follow-up of 12 months and no relapse of the symptoms. Conclusion: The high rate of surgical complications in patients with Parkinson's disease, in contrast to the low rate of complications in the present study, suggests that minimally invasive surgery of the lumbar spine should be a surgical alternative in these patients. Level of Evidence: IV

ABSTRACT

Introdução: O objetivo do trabalho é relatar um caso de ceratocisto associado à impactação dentária, o qual foi tratado com descompressão, seguido de enucleação da lesão e utilização de solução de Carnoy. Relato de caso: Paciente do sexo masculino, 14 anos, encaminhado para avaliação de lesão encontrada após exame imaginológico de rotina. O mesmo demonstrou extensa lesão radiolúcida localizada na região de ângulo e ramo da mandíbula, com presença do elemento 48 intralesional próximo a basilar. Foi realizado biópsia incisional e instalação de dispositivo de descompressão no mesmo tempo cirúrgico, o qual o resultado histopatológico foi de ceratocisto. Após 6 meses com o dispositivo, observou-se diminuição da lesão e melhora no posicionamento do dente incluso. Frente a boa resposta à descompressão, decidiu-se pela enucleação total da lesão, exodontia dos dentes 47 e 48, curetagem rigorosa e tereapia adjuvante com aplicação da solução de Carnoy. O paciente evoluiu bem, neoformação óssea na área operada e encontra-se em acompanhamento há 6 meses, sem sinais de recidiva. Considerações finais: O uso da descompressão cirúrgica em lesões císticas mandibulares minimiza os danos as estruturas circunvizinhas, riscos de fratura patológica e lesão nervosa. Em função das altas taxas de recidiva, a terapia adjuvante após a enucleção é imprescindível para essa lesão, sendo a aplicação da solução de Carnoy uma das técnicas com melhores resultados. Dessa forma, para aumentar a taxa de sucesso e minimizar as sequelas, o planejamento cirúrgico dos ceratocistos mandibulares extensos deve ser feito de forma criteriosa e cuidadosa... (AU)


Introduction: The objective of this study is to report a case of keratocyst associated with dental impaction, which was treated with decompression, followed by enucleation lesion and Carnoy solution. Case report: Male patient, 14 years old, referred for evaluation of lesion found after routine imaging. He showed extensive radiolucent lesion located in the region of the angle and branch of the mandible, with the presence of the intralesional element 48 near the basilar. An incisional biopsy was performed and a decompression device was installed during surgical time and the histopathological result was keratocyst. After 6 months of observation a reduction of the lesion and improvement in the positioning of the tooth even were noticed. Given the good response to decompression, it was decided to complete the enucleation of the lesion, extraction of teeth 47 and 48, rigorous curettage and adjuvant therapy with Carnoy's solution. Followed up for 6 months, patient evolved well creating a new bone formation in the operated area with no signs of relapse. Final considerations: The use of surgical decompression in cystic mandibular lesions minimizes damage to surrounding structures, pathological fracture risks, and nerve damage. Because of the high rates of recurrence, keratocysts require adjuvant therapy after enucleation and Carnoy's solution is one of the best performing techniques. Thus, to increase success rate and minimize sequelae, the surgical planning of extensive mandibular keratocysts should be done carefully and judiciously... (AU)

ABSTRACT

The odontogenic keratocyst is a lesion with specific clinical and histopathological aspects. The World Health Organization (WHO) in 2017 reclassified it from a tumor to a cyst. It is characterized as a cyst of epithelial development of the jaws, arising from the remains of the dental blade. It represents 3 % to 11 % of all odontogenic cysts and 7 to 11 % of cysts of the gnatic bones. It stands out for its aggressive nature and high relapsing potential. Most of the cases are diagnosed in individuals between 10 and 40 years old, with a mild preference for the masculine gender, occurring more in the mandible. Radiographically, it is radiolucent and well delimited, predominantly unilocular, and may cause displacement of adjacent teeth. The present study aims to report a clinical case of a female 25 years old patient, presenting an intra-osseous lesion in the maxilla (posterior, left side), asymptomatic, with a slight increase in intraoral buccal volume, containing the tooth 28, with a diagnostic hypothesis of Odontogenic Keratocyst. The patient was submitted to the surgical decompression treatment, with cystic fluid puncture, biopsy of the lesion and posterior anatomopathological examination. The enucleation of the tumor was performed using LeFort I osteotomy of maxilla and reconstruction with titanium mesh. There is radiographic evidence of bone repair and lesion reduction. The patient is in periodic follow-up of 4 years and does not present clinical and radiographic signs of relapse. Due to the aggressiveness of the odontogenic keratocyst, the relapse rate is high. The knowledge of the techniques recommended for the treatment of Odontogenic Keratocysts and the clinical and radiographic follow-up of the patient demonstrate a gradual decrease of the lumen of the lesion and suggest local bone neoformation, favoring the prognosis of the case.


El queratoquiste odontogénico es una lesión con aspectos clínicos e histopatológicos específicos. La Organización Mundial de la Salud (OMS) en 2017 lo reclasificó de un tumor a un quiste. Se caracteriza como un quiste de desarrollo epitelial de las mandíbulas, que surge de los restos de la lámina dental. Representa del 3 % al 11 % de todos los quistes odontogénicos y del 7 al 11 % de los quistes de los huesos gnáticos. Se destaca por su naturaleza agresiva y su alto potencial de recaídas. La mayoría de los casos se diagnostican en individuos de entre 10 y 40 años, con una leve preferencia por el sexo masculino, que ocurre más en la mandíbula. Radiográficamente, es radiotransparente y bien delimitado, predominantemente unilocular, y puede causar el desplazamiento de los dientes adyacentes. El presente estudio tiene como objetivo reportar el caso clínico de una paciente de 25 años, que presenta una lesión intraósea en el maxilar (posterior, lado izquierdo), asintomática, con un ligero aumento en el volumen bucal intraoral, que contiene el diente 28, con una hipótesis diagnóstica de queratoquiste odontogénico. El paciente fue sometido al tratamiento quirúrgico de descompresión, con punción de líquido quístico, biopsia de la lesión y examen anatomopatológico posterior. La enucleación del tumor se realizó con osteotomía LeFort I de maxilar y reconstrucción con malla de titanio. Existe evidencia radiográfica de reparación ósea y reducción de la lesión. El paciente se encuentra en seguimiento periódico de 4 años y no presenta signos clínicos ni radiográficos de recaída. Debido a la agresividad del queratoquiste odontogénico, la tasa de recaída es alta. El conocimiento de las técnicas recomendadas para el tratamiento de los queratoquistes odontogénicos, y el seguimiento clínico y radiográfico del paciente, demuestran una disminución gradual del lumen de la lesión y sugieren neoformación ósea local, favoreciendo el pronóstico del caso.

ABSTRACT Objectives: To describe the therapeutic effect of the stem cell use in managing osteonecrosis of the femoral head. Methods: A search was carried out in the different databases as Pubmed / MEDLINE, BVS and Cochrane for the last 10 years, including relevant meta-analysis studies, clinical trials and reviews. In addition, the official website of the World Health Organization was checked for additional references. The search words were: "(" Stem Cells "OR" Stem Cell Transplantation "[Mesh] OR" Mesenchymal Stem Cell Transplantation "[Mesh] OR Hematopoietic Stem Cell Transplantation" [Mesh] OR Cell-and Tissue-Based Therapy "[ Mesh] "Multipotent Stem Cells" [Mesh] OR "Embryonic Stem Cells" [Mesh]) AND ("Osteonecrosis" [Mesh] OR "Femur Head Necrosis" [Mesh] "osteonecrosis of the femoral head" OR "Femoral head"). We include a total of 7 studies, 2 meta-analyzes, 2 review articles, 2 controlled and randomized clinical trials, and one evidence study. Findings: All the studies showed that stem cell therapy in managing osteonecrosis of the femoral head is safe and effective. The combined treatment of central decompression plus stem cell implantation showed greater effectiveness. Conclusions: Stem cell therapy is a therapeutic option to treat osteonecrosis of the femoral head, especially in the early stages. The combination of central decompression plus the infiltration of stem cells in the necrotic area produces an improvement in the symptoms and contains the progress of the disease(AU)

ABSTRACT

SUMMARY BACKGROUND Symptomatic Chiari Type I Malformation (CM) is treated with posterior fossa decompression with or without duroplasty. We have noticed some cases with concomitant severe cerebellar ataxia due to cerebellar atrophy. The aim of this study is to review the literature of CM associated with severe cerebellar atrophy and discuss its potential physiopathology. METHODS A systematic literature review in the Pubmed Database was performed using the following key-terms: "cerebellar atrophy Chiari", and "cerebellar degeneration Chiari". Articles reporting the presence of cerebellar degeneration/atrophy associated with CM were included. RESULTS We found only six studies directly discussing the association of cerebellar atrophy with CM, with a total of seven cases. We added one case of our own practice for additional discussion. Only speculative causes were described to justify cerebellar atrophy. The potential causes of cerebellar atrophy were diffuse cerebellar ischemia from chronic compression of small vessels (the most mentioned speculative cause), chronic raised intracranial pressure due to CSF block, chronic venous hypertension, and association with platybasia with ventral compression of the brainstem resulting in injury of the inferior olivary nuclei leading to mutual trophic effects in the cerebellum. Additionally, it is not impossible to rule out a degenerative cause for cerebellar atrophy without a causative reason. CONCLUSIONS Severe cerebellar atrophy is found in some patients with CM. Although chronic ischemia due to compression is the most presumed cause, other etiologies were proposed. The real reasons for cerebellar degeneration are not known. Further studies are necessary.


RESUMO OBJETIVO A Malformação de Chiari (MC) tipo I sintomática é tratada através da descompressão da fossa posterior com ou sem duroplastia. Observamos alguns casos com ataxia cerebelar grave concomitante devido à atrofia cerebelar. O objetivo deste estudo é revisar a literatura sobre MC associada à atrofia cerebelar grave e discutir sua possível fisiopatologia. METODOLOGIA Conduzimos uma revisão sistemática da literatura no banco de dados Pubmed utilizando as seguintes palavras-chave: "cerebellar atrophy Chiari", e "cerebellar degeneration Chiari". Artigos sobre a presença de degeneração/atrofia cerebelar associada à MC foram incluídos. RESULTADOS Encontramos apenas seis estudos que discutiam diretamente a associação entre atrofia cerebelar e MC, com um total de sete casos. Nós adicionamos um caso da nossa própria prática para ampliar a discussão. Apenas causas especulativas foram descritas para justificar a atrofia cerebelar, entre elas: isquemia cerebelar difusa devido à compressão crônica de pequenos vasos (a causa especulativa mais citada), pressão intracraniana elevada crônica devido ao bloqueio de LCR, hipertensão venosa crônica e associação com platibasia com compressão ventral do tronco cerebral, resultando em lesão do núcleo olivar inferior e levando a efeitos tróficos mútuos no cerebelo. Além disso, não é possível descartar uma causa degenerativa para atrofia cerebelar sem motivos claros. CONCLUSÃO A atrofia cerebelar grave é encontrada em alguns pacientes com MC. A isquemia crônica causada por compressão é a causa mais apontada como suspeita, porém outras etiologias foram propostas. As reais causas da degeneração cerebelar não são conhecidas. Mais estudos são necessários.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy and advantages of the full endoscopic I See technique for the single-segment degenerative lumbar spinal stenosis.@*METHODS@#The clinical data of 38 patients with the single-segment degenerative lumbar spinal stenosis treated by full endoscopic I See technique from January 2017 to March 2018 were analyzed retrospectively. There were 16 males and 22 females, aged from 35 to 79 years with an average of(53.45±12.56) years. Five cases were L, 23 cases were L, 10 cases were LS. The clinical efficacy was evaluated by VAS, ODI and Macnab scores.@*RESULTS@#All the patients were followed up for more than 12 months after operation. The length of operation was from 55 to130 (86.0± 17.5) min. Intraoperative blood loss was ranging from 10 to 50 (17±6) ml, and the hospitalization length was from 3 to 7 days with an average of 4.6 days. The VAS scores of low back pain assessed before operation, and 3 d, 3 months, 12 months post operation were 6.67 ±1.25, 3.87 ±1.35, 2.55 ±1.21, 2.05 ±0.97, respectively, and the differences were statistically significant (P < 0.05);VAS scores of leg pain at these time points were 7.85±2.62, 3.31±1.42, 2.02±1.13, 1.85±0.86, respectively, and the differences were statistically significant (<0.05);ODI scores were 40.32±5.38, 25.76±4.81, 12.66±4.64, 9.32±2.91, respectively, and the differences were statistically significant (<0.05). Tevaluate the lumbar vertebrae function according to the Macnab criteria, 15 cases obtained excellent results, 19 cases were good, and 4 cases were fair.@*CONCLUSION@#Full endoscopic I See technique is effective in the treatment of single-segment degenerative lumbar spinal stenosis, with the advantages of less trauma, shorter hospital stay, and faster recovery.

ABSTRACT

OBJECTIVE@#To evaluate the clinical effects of percutaneous endoscopic foraminoplasty for simple lumbar spinal lateral exit zone stenosis.@*METHODS@#A total of 36 patients with simple lumbar spinal lateral exit zone stenosis were admitted to our hospital from January 2013 to June 2018, and received selective nerve root canal radiography and radicular block. According to the symptoms and patients' personal wills, 22 cases underwent the one-stage percutaneous foraminal surgery(the one-stage operation group), and the other 14 patients were re-admitted to the hospital for operation(the delayed operation group) because of the recurrence of symptoms after discharge. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the clinical effects before therapy, 1 day after the radicular block, and 1 day, 3 months and 6 months after the operation.@*RESULTS@#VAS and ODI of all 36 cases were obviously improved (0.05), but when compared with its own pretherapy andbefore readmission results, the difference was significant (<0.05). There was no nerve injury in all cases. Only 2 cases were presented with the outlet root stimulation symptoms, and the symptoms relieved after short term conservative treatment.@*CONCLUSION@#The clinical effects of radicular block may be unsustainable for patients with simple lumbar spinal lateral exit zone stenosis. Instead, percutaneous endoscopic foraminoplasty was simple, safe and effective.

ABSTRACT

OBJECTIVE@#To explore the safety, effectiveness and consistency of "Zoning Method" foraminotomy in posterior cervical endoscopic surgery.@*METHODS@#From March 2016 to October 2018, 21 patients with cervical spondylotic radiculopathy were enrolled. Endoscopic foraminotomy and nucleus pulposus enucleation were performed in the patients. There were 13 males and 8 females, aged from 35 to 56 years old with an average of (47.3±5.1) years. The surgical segment of 6 cases were C, 10 cases were C and 5 cases were C. The "Zoning Method" was proposed and used to complete the foraminotomy under endoscope, and then to perform nucleus pulposus removal and nerve root decompression. The operation length, intraoperative bleeding volume and complications were recorded, and NDI, VAS were evaluated before operation, 1 day after the operation and 1 week after the operation.@*RESULTS@#All the operations were successful. The operation length was(46.10±26.39) min, intraoperative bleeding volume was (50.10±18.25) ml, and there were no complications such as nerve injury, dural tear or vertebral artery injury. All 21 patients were followed up for 3 to 9 months, with a median of 6 months. Postoperative VAS and NDI were obvious improved (0.05).@*CONCLUSION@#Endoscopic foraminotomy with "Zoning Method" is safe clinically significant, and consistent.

ABSTRACT

OBJECTIVE@#To systematically assess the efficacy of anterior cervical corpectomy and fusion (ACCF) versus posterior laminoplasty (LAMP) for cervical ossification of posterior longitudinal ligament (OPLL).@*METHODS@#PubMed and EMBASE, Cochrane Library, CBM, CNKI, Wanfang and VIP were collected from 7 databases of ACCF, LAMP from 1970 to May 2018. According to the criteria, the articles were included and independently screened by two authors. The quality of the articles was assessed by using the MINORS scale (methodological index for non randomized studies). After extracting the data from the article, the JOA score, cervical curvature, operation time, bleeding volume, excellent and good rate, recovery rate, adverse events and secondary surgery were analyzed by using Review Manager 5.3 software.@*RESULTS@#Finally, a total of 22 articles with 1 678 patients were included in this Meta-analysis, with 810 patients in ACCF group and 868 patients in LAMP group. Meta analysis results showed that the ACCF group had higher postoperative JOA scores[MD=0.63, 95%CI(0.05, 1.20), = 0.03], higher excellent rate [=1.85, 95%CI (1.14, 3.02), =0.01] and higher recovery rate [=11.90, 95%CI (5.75, 18.05), =0.000 1]. But the LAMP group has a shorter operative time [MD=52.19, 95%CI (29.36, 75.03), <0.000 01], less complications [=1.56, 95%CI (1.03, 2.35), =0.04] and less reoperations [=3.73, 95%CI (1.62, 8.57), =0.002]. There was no significant different in postoperative lordosis [MD=3.15, 95%CI(-0.14, 6.43), =0.06] and blood loss[SMD= 0.26, 95%CI(-0.05, 0.57), =0.10] between two groups.@*CONCLUSION@#The recovery of functionof ACCF group was better, but operation time, complications and reoperations of LAMP group were all better than ACCF group. There was no difference in postoperative lordosis and intraoperative blood loss between two groups. However, there are some limitations in this study. Therefore, higher quality and larger sample size clinical studies are needed to further verify.

ABSTRACT

OBJECTIVE@#To observe the clinical effect of platelet rich plasma (PRP) combined with β tricalcium phosphate bioceramic bone in the treatment of non traumatic necrosis of the femoral head in ARCO stageⅡ.@*METHODS@#From January 2017 to December 2018, 100 patients (160 hips) with ARCO stageⅡnon traumatic necrosis of the femoral head were divided into PRP group and control group. In PRP group, 50 patients (80 hips), 22 males and 28 females, aged from 18 to 65 (43.47± 7.23) years, with a course of 4 to 18 (15.8±2.9) months, underwent core decompression and bone grafting combined with PRP implantation. There were 50 cases (80 hips) in the control group, including 27 males and 23 females, aged 20 to 63 (45.72± 7.43) years, and the course of disease was 6 to 19 (14.9±3.8) months. Hip X-ay film was followed up after operation. Harris score and VAS score were used to evaluate the curative effect, and the survival rate of hip joint was recorded.@*RESULTS@#All patients had good wound healing, no infection, thrombosis and other complications. All patients were followed up for 12 to 14 (12.0±0.4) months. Twelve months after operation, the image expression of PRP group was better than that of control group(@*CONCLUSION@#Platelet-rich plasma(PRP) combined with artificialbone for core decompression and bone grafting can change the situation of simple artificial bone implantation and uncertain curative effect, improve the success rate of this operation, effectively reduce the collapse rate of femoral head necrosis in the early and middle stage, delay or even avoid hip replacement.

ABSTRACT

BACKGROUND@#The optimal surgical approach for four-level cervical spondylotic myelopathy remains controversial. The purpose of this study was to compare clinical and radiological outcomes and complications between the anterior and posterior approaches for four-level cervical spondylotic myelopathy.@*METHODS@#A total of 19 patients underwent anterior decompression and fusion and 25 patients underwent posterior laminoplasty and instrumentation in this study. Perioperative information, intraoperative blood loss, clinical and radiological outcomes, and complications were recorded. Japanese Orthopedic Association (JOA) score, 36-item short form survey (SF-36) score and cervical alignment were assessed.@*RESULTS@#There were no significant differences in JOA scores between the anterior and posterior group preoperatively (11.6 ± 1.6 vs. 12.1 ± 1.5), immediately postoperatively (14.4 ± 1.1 vs. 13.8 ± 1.3), or at the last follow-up (14.6 ± 1.0 vs. 14.2 ± 1.1) (P > 0.05). The JOA scores significantly improved immediately postoperatively and at the last follow-up in both groups compared with their preoperative values. The recovery rate was significantly higher in the anterior group both immediately postoperatively and at the last follow-up. The SF-36 score was significantly higher in the anterior group at the last follow-up compared with the preoperative value (69.4 vs. 61.7). Imaging revealed that there was no significant difference in the Cobb angle at C2-C7 between the two groups preoperatively (-2.0° ± 7.3° vs. -1.4° ± 7.5°). The Cobb angle significantly improved immediately postoperatively (12.3° ± 4.2° vs. 9.2° ± 3.6°) and at the last follow-up (12.4° ± 3.5° vs. 9.0° ± 2.6°) in both groups compared with their preoperative values (P = 0.00). Three patients had temporary dysphagia in the anterior group and four patients had persistent axial symptoms in the posterior group.@*CONCLUSIONS@#Both the anterior and posterior approaches were effective in treating four-level cervical spondylotic myelopathy in terms of neurological clinical outcomes and radiological features. However, the JOA score recovery rate and SF-36 score in the anterior group were significantly higher. Persistent axial pain could be a major concern when undertaking the posterior approach.
