ABSTRACT

ABSTRACT Objective To analyze the results of the use of dexmedetomidine (D) in the treatment of patients with degenerative diseases of the lumbar spine using puncture techniques. Methods The study included 77 patients who underwent surgical puncture for degenerative diseases of the lumbar spine with the use of alpha-2-adrenomimetic D: percutaneous laser denervation of the facet joints (n = 46) and posterolateral transforaminal endoscopic discectomy (n = 31). We assessed: the level of sedation using the Ramsay Sedation Scale (RSS) and the Richmond Agitation Sedation Scale (RASS); intraoperative dynamics of the cardiovascular and respiratory system parameters; the level of pain syndrome according to VAS. Results A high intraoperative level of sedation was determined, with RASS -2, -3 and Ramsay III, IV; when transferring a patient to a department (in 90 minutes) this parameter was RASS 0 and Ramsay II. There were no significant changes in central hemodynamics and respiratory depression. The minimum level of pain was determined immediately after surgery, at 30 and 60 minutes after surgery, and before transfer to the department (90 minutes): 6 (4;9); 10 (8;12); 12 (9;13); 16 (13;19) respectively. The absence of the need for additional analgesia on the first postoperative day was verified. Conclusion The use of D significantly reduces the level of pain, while maintaining the necessary verbal contact with the patient, and provides the necessary neurovegetative protection without respiratory depression or lowered hemodynamic parameters during the perioperative period. Level of evidence II; Prognostic Studies - Investigating the Effect of a Patient Characteristic on Disease Outcome. Case series, retrospective study.


RESUMO Objetivo Analisar os resultados do uso de dexmedetomidina (D) no tratamento de pacientes com doenças degenerativas da coluna lombar com técnicas de punção. Métodos O estudo incluiu 77 pacientes submetidos à punção cirúrgica em doenças degenerativas da coluna lombar com o uso de um agonista alfa-2 adrenérgico: denervação percutânea das articulações facetárias com laser (n = 46) e discectomia endoscópica transforaminal posterolateral (n = 31). Foram avaliados o nível de sedação usando a Escala de Sedação de Ramsay (RSS) e a Escala de Sedação e Agitação de Richmond (RASS); a dinâmica intraoperatória dos parâmetros dos sistemas cardiovascular e respiratório; o nível de síndrome de dor de acordo com a EVA. Resultados Determinou-se um alto nível intraoperatório de sedação pela RASS (-2, -3) e pela Ramsay (III, IV). Ao transferir um paciente para outro setor (depois de 90 minutos), esse parâmetro era 0 em RASS e II em Ramsay. Não houve alterações significativas na hemodinâmica central e na depressão respiratória. O nível mínimo de dor foi determinado imediatamente após a cirurgia, 30 e 60 minutos depois da cirurgia e antes da transferência para o outro setor (90 minutos depois): 6 (4; 9); 10 (8; 12); 12 (9; 13); 16 (13; 19), respectivamente. Constatou-se que não era necessária analgesia adicional no primeiro dia pós-operatório. Conclusões O uso de D reduz significativamente o nível de dor mantendo a comunicação verbal necessária com o paciente e fornece a proteção neurovegetativa necessária sem depressão respiratória e os parâmetros hemodinâmicos reduzidos durante o período perioperatório. Nível de evidência II; Estudos prognósticos - Investigação do efeito de característica de um paciente sobre o desfecho da doença. Série de casos, Estudo retrospectivo.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and security of posterior percutaneous endoscopic cervical discectomy (PPECD) in the treatment of single level cervical spondylopathy with intraspinal ossification.@*METHODS@#Twenty three patients with single level cervical spondylopathy with intraspinal ossification were treated by posterior percutaneous endoscopic cervical discectomy between August 2017 and July 2019. There were 16 males and 7 females, aged from 29 to 74 years old with an average of (50±13) years.The disease duration were 3 to 120 months with a median of 6 months. There were 9 cases of cervical spondylotic radiculopathy, 6 cases of cervical spondylotic myelopathy, and 8 cases of mixed cervical spondylopathy. According to the characteristics of ossification, 17 cases were osteophytes on the posterior edge of the vertebral body;3 cases were protrusion ossification;3 cases were posterior longitudinal ligament ossification. According to the position of ossification in spinal canal, 14 cases were medial and lateral type, 5 cases were central type, and 4 cases were mixed type. Posterior percutaneous cervical endoscopic cervical discectomy in patients performed by the same surgeon. Japanese Orthopaedic Association (JOA) score and visual analogue scale(VAS) were compared separately before and after operation. At 3 months after operation, clinical effect was assessed according to modified Macnab standard.@*RESULTS@#All operations were successful. The operative time was 30 to 155 (69.1±27.2) min. The bedridden time was 2 to 3(3.0±0.9) h, length of postoperative hospitalization was 2 to 7(4.1± 1.5) d. Three dimensional CT reconstruction of the cervical spine at 3 days after operation showed that ossified tissue of 13 cases were completely removed, and 10 cases were left after operation, and the residual was located at the posterior edge and/or center of the upper vertebral body. VAS score at discharge from hospital was significantly lower than that before operation (@*CONCLUSION@#For an experienced surgeon, percutaneous posterior cervical endoscopic discectomy is safe and reliable in treating single level cervical spondylopathy with intraspinal ossification, and can obtain good clinical results.

ABSTRACT

Introducción: La Discectomía Endoscópica Lumbar Percutánea (DELP) es una técnica mínimamente invasiva que se usa en distintos países desde finales de los ochenta para el tratamiento de las Hernias Discales. Objetivo: El propósito del presente artículo es presentar los resultados de la evolución clínica de 110 pacientes operados de distintas hernias discales lumbares por técnica endoscópica percutánea, con seis meses de seguimiento. Asimismo, describir la técnica realizada y los aspectos más relevantes del planning preoperatorio, entre ellos el punto de ingreso percutáneo. Materiales y Métodos: En un grupo de 110 pacientes y 141 discos operados entre abril de 2016 y octubre de 2019, se recogieron datos como la edad, el sexo, la clínica, las imágenes de RMN y el planning del ingreso (Skin Entry Point) con target en el fragmento discal herniado. Se realizó en todos los casos una fragmentectomía dirigida, y luego se complementó con técnica In-Out. Se registró, como dato principal, la diferencia en los puntajes de Oswestry (ODI) pre y postquirúrgico a los 6 meses del procedimiento. También se constató la duración de la operación, el tiempo de hospitalización, y la necesidad de reintervención. Todos los pacientes se operaron despiertos, recibiendo anestesia peridural y sedación. Resultados: Se operaron 110 pacientes y 141 hernias discales. El promedio de reducción en ODI a los 6 meses fue 47,5 puntos (SD=5,7), representando un porcentaje medio de reducción de 85% (SD=9,5). Desde el punto de vista técnico se logró promediar la distancia de línea media al ingreso o Skin Entry Point, según el nivel operado y el abordaje elegido. Conclusión: a la luz de los resultados en nuestra serie de 110 pacientes con hernias discales lumbares, operados despiertos por endoscopía percutánea, se obtuvieron mejorías en el dolor promedio del 85% a seis meses. La técnica endoscópica puede ser considerada como un procedimiento efectivo para pacientes con hernias foraminales, extraforaminales y centrales en los niveles L3L4, L4L5 y L5S1.


Introduction: Introduction: PELD is a minimally invasive technique that has been used in different countries since the late 1980s for the treatment of Herniated Discs. Objective: to describe the surgical method from the Approach point of view and PELD results in a series of 110 patients. Materials and Methods: In a group of 110 patients who together had 141 discs operated on between April 2016 and October 2019, data were collected on patients age and gender, clinical presentation, MRI abnormalities and Skin Entry Point (SEP) with target in the herniated disc fragment. A focused fragmentectomy was performed in all cases, and then it was complemented with an In-Out technique. The main result was the difference in the pre and postoperative Oswestry Disability Index (ODI) scores 6 months after the procedure. The operation duration, the lenght of hospitalization, and the need for reoperation were also recorded. All patients underwent surgery awake, receiving epidural anesthesia and sedation. Results: Respecting the SEP of the endoscope according to the MRI planning focused in the herniated fragment, the evolution of the patients was very favorable. The average reduction in ODI at 6 months was 47.5 points (SD = 5.7), representing an average percentage reduction of 85% (SD = 9.5). The average surgery time was 58 minutes, and the hospitalization time 8.5 hours. Conclusions: In our series of surgical patients with lumbar disc herniations, PELD with focused fragmentectomy in awake patients proved to be a technique with very good results, especially with prior planning of the SEP to achieve effective root decompression

ABSTRACT

Introducción: Las infecciones del sitio quirúrgico pueden requerir tratamientos prolongados con antibióticos, una estancia hospitalaria más prolongada y operaciones repetidas. Las incisiones pequeñas y la posibilidad de evitar la disección subperióstica en la cirugía mininvasiva pueden reducir, al mínimo, el riesgo de infecciones posoperatorias. Sin embargo, los estudios publicados sobre infecciones después de procedimientos mininvasivos son escasos. El objetivo de este estudio fue evaluar retrospectivamente una serie de pacientes operados, de manera consecutiva, con una técnica mininvasiva y la incidencia de infección posoperatoria. Materiales y Métodos: Se incluyó a los pacientes sometidos a cirugía lumbar posterior con retractores tubulares y microscopio, en nuestro Servicio, entre enero de 2015 y enero de 2018. Los procedimientos realizados fueron discectomías tubulares, descompresiones para la estenosis de canal y resecciones de quistes sinoviales. La incidencia de infección del sitio quirúrgico se calculó y comparó con el rango de tasas de infección del sitio quirúrgico publicado. Resultados: Se realizaron cirugías no instrumentadas (discectomías, descompresiones) en 212 pacientes. La media de la edad era de 62.4 años y la relación hombre:mujer, de 1,27:1. Solo un paciente sufrió una infección del sitio quirúrgico, diagnosticada el día 9 poscirugía, que fue tratada mediante lavado y limpieza de la herida. Conclusión: La tasa de infección fue del 0,47%. La cirugía mininvasiva puede disminuir notablemente la tasa de infección del sitio quirúrgico y puede ser una herramienta eficaz para reducir, al mínimo, los costos hospitalarios. Nivel de Evidencia: IV


Introduction: Surgical site infections (SSI) can lead to prolonged antibiotic treatments, increased hospital stays, and repeated operations. Small incisions and the possibility of avoiding subperiosteal dissection in minimally invasive surgery can minimize the risk of postoperative infections. However, there is a shortage of literature on infections after mini-invasive procedures. Objective: To evaluate retrospectively a series of patients consecutively operated on with minimally invasive technique and the incidence of postoperative infection. Materials and Methods: All patients undergoing posterior lumbar surgery with tubular retractors and microscope in our department from January 2015 to January 2018 were included. The procedures performed included tubular discectomies, lumbar stenosis decompressions, and synovial cyst resections. The incidence of postoperative SSIs was calculated and compared with the literature range for SSI rates. Results: A total of 212 patients underwent non-instrumented surgeries (discectomies, decompressions). The mean age was 62.4 years with a male:female ratio of 1.27:1. Only one patient had SSI, which was diagnosed on day 9 and treated by reoperation, surgical toilet of the wound, and antibiotic therapy. Conclusion: The infection rate was 0.47%. Minimally invasive surgery can significantly reduce the SSI rate and can be an effective tool in minimizing hospital costs. Level of Evidence: IV

ABSTRACT

RESUMEN Fundamento: La enfermedad degenerativa cervical produce una variedad de síntomas clínicos que pueden ser tratados de forma no quirúrgica, sin embargo en ocasiones la cirugía es necesaria. La técnica quirúrgica más empleada para tratar esta enfermedad es la discectomía con artrodesis. El tratamiento adecuado de la hernia discal cervical depende de una adecuada selección de la técnica quirúrgica y su correcta realización. Objetivo: Caracterizar el tratamiento quirúrgico de la hernia discal cervical en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus en el período: enero de 2015 a diciembre de 2018. Metodología: Se realizó un estudio prospectivo en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus de enero 2015 a diciembre 2018. La población de estudio: todos los pacientes que acudieron a la consulta externa de neurocirugía del hospital refiriendo cervicalgia o cervicobraquialgia; la muestra: 51 pacientes diagnosticados por resonancia magnética nuclear de hernia discal cervical y que se les realizó al menos una discectomía cervical. Resultados: De los pacientes el 62.8 % eran mujeres y el 33.3 % tenía una edad comprendida entre 51-60 años. El espacio intervertebral más afectado fue C5-C6 (43.7 %). La técnica quirúrgica que predominó fue la discectomía con colocación de injerto autólogo (79.7 %). La complicación más frecuente fue la expulsión del injerto (3.9 %). Conclusiones: El comportamiento de la hernia discal en cuanto al sexo, edad y nivel afectado fue similar al descrito en la bibliografía. La técnica quirúrgica más empleada fue la artrodesis con injerto autólogo de cresta ilíaca. Las complicaciones presentadas fueron infrecuentes.


ABSTRACT Background: Cervical degenerative disease produces a variety of clinical symptoms that can be treated by a non-surgical way, however sometimes surgery is necessary. The most widely used surgical technique to treat this disease is discectomy with arthrodesis. The proper treatment of cervical disc herniation depends on an adequate selection of the surgical technique and its correct performance. Objective: To characterize the surgical treatment of cervical disc herniation at Camilo Cienfuegos General Provincial Hospital in Sancti Spíritus in the period: January 2015 to December 2018. Methodology: A prospective study was carried out at Camilo Cienfuegos General Provincial Hospital in Sancti Spíritus from January 2015 to December 2018. The study population: all the patients who attended the hospital outpatient neurosurgery consultation referring cervicalgia or cervicobraquialgia; the sample: 51 patients diagnosed with cervical disc herniation and performed at least one cervical discectomy. Results: Of the patients, 62.8 % were women and 33.3 % were between 51-60 years old. The most affected intervertebral space was C5-C6 (43.7 %). The predominant surgical technique was discectomy with autologous graft placement (79.7 %). The most frequent complication was the expulsion of the graft (3.9 %). Conclusions: The behavior of the herniation disc concerning sex, age and affected level was similar to that described in the literature. The most widely used surgical technique was arthrodesis with an autologous iliac crest graft. The complications presented were infrequent.

ABSTRACT

ABSTRACT Objective To assess postoperative outcomes following lumbar microdiscectomy (LMD) with and without the use of a dynamic intralaminar device IntraSPINE ® . Methods A non-randomized single-surgeon retrospective analysis. Consecutive elective surgery was performed on patients with lumbar disc disease over a 16-month period. The study group was determined by electronic theatre database. Ninety-two (62 LMD and 30 ILD) of the 95 eligible patients were included in the study, with three being excluded due to incomplete data sets. The pain scores were assessed pre- and postoperatively using a 4-point scale (0 - pain free; 1 - mild; 2- moderate; 3 - severe). Results The reduction in postoperative leg pain was similar (LMD 1.9 vs. IntraSPINE® 1.8) but the reduction in postoperative back pain was greater in the IntraSPINE® group (LMD 0.5 vs. IntraSPINE® 1.0; p = 0.17). Early recurrence of disc herniation (< 8 months) was lower in the IntraSPINE® group (6.7% vs. 19.4%; p = 0.097). The need for revision surgery was significantly lower in the IntraSPINE® group (p = 0.015). None of the IntraSPINE® recurrences required revision surgery, compared to 97% of the recurrences in the LMD group. Conclusions This case series raises the possibility that in selected patients, the use of the IntraSPINE® may improve back pain and reduce recurrent disc herniation/revision surgery rates in lumbar microdiscectomy. A prospective randomized trial on the use of the IntraSPINE® should be considered, given the clinical and cost implications of revision surgery. Level of Evidence IV; Case series.


RESUMO Objetivo Avaliar os resultados pós-operativos de microdiscectomia lombar (MDL) usando ou não o dispositivo intralaminar dinâmico IntraSPINE®. Métodos Análise retrospectiva simples não randomizada feita por um único cirurgião de cirurgias eletivas consecutivas em pacientes com hérnia de disco lombar no período de 16 meses. O grupo de estudo foi determinado por um banco de dados eletrônicos de centro cirúrgico. Noventa e dois (62 MDL e 30 com dispositivos intralaminares, ILD) dos 95 pacientes elegíveis foram incluídos na pesquisa, sendo que três foram excluídos porque os dados eram incompletos. Os escores de dor foram avaliados no pré e pós-operatório com uma escala de 4 pontos (sendo 0 - sem dor, 1 - leve, 2 - moderada e 3 -severa). Resultados A redução da dor nas pernas no pós-operatório foi similar (MDL 1,9 vs. IntraSPINE® 1,8), mas a redução da dor nas costas no pós-operatório foi melhor no grupo IntraSPINE® (MDL 0,5 vs. IntraSPINE® 1,0; p = 0,17). A reincidência precoce de hérnia de disco (< 8 meses) foi menor no grupo IntraSPINE® (6,7% vs. 19,4%; p = 0,097). A necessidade de cirurgia de revisão foi significativamente menor no grupo IntraSPINE® (p= 0,015). Nenhuma das reincidências no grupo com IntraSPINE® exigiu cirurgia de revisão em comparação com 97% das reincidências do grupo MDL. Conclusões Esta série de casos levanta a possibilidade de que, em pacientes selecionados, o uso de IntraSPINE® pode reduzir a dor nas costas e as taxas de recidiva de hérnia de disco e de cirurgias de revisão na microdiscectomia lombar. Um estudo prospectivo e randomizado do uso do IntraSPINE® deve ser considerado, dadas as implicações clínicas e o custo da cirurgia de revisão. Nível de Evidência IV; Série de casos.


RESUMEN Objetivo Evaluar los resultados postoperatorios de la microdiscectomía lumbar (MDL) utilizando o no el dispositivo intralaminar dinámico IntraSPINE®. Métodos Análisis retrospectivo simple y no aleatorio realizado por uno solo cirujano de cirugías electivas consecutivas en pacientes con hernia de disco lumbar durante un período de 16 meses. El grupo de estudios fue determinado por una base de datos electrónicos de centro quirúrgico. Noventa y dos (62 MDL y 30 con dispositivos intralaminares, ILD) de los 95 elegibles fueron incluidos en el estudio, siendo que tres fueron excluidos porque los datos estaban incompletos. Las puntuaciones de dolor se evaluaron antes y después de la operación con una escala de 4 puntos (0: sin dolor, 1: leve, 2: moderado, 3: grave). Resultados La reducción del dolor postoperatorio de pierna fue similar (MDL 1,9 versus IntraSPINE® 1,8). Sin embargo, la reducción del dolor postoperatorio de la espalda fue mayor en el grupo con IntraSPINE® (MDL 0,5 versus IntraSPINE® 1,0; p = 0,17). La recurrencia temprana de hernia del disco (< 8 meses) fue menor en el grupo IntraSPINE® (6,7% versus 19,4%; p = 0,097). La necesidad de cirugía de revisión fue significativamente menor en el grupo IntraSPINE® (p = 0,015). Ninguna de las recurrencias en el grupo IntraSPINE® requirió cirugía de revisión en comparación con 97% de las recurrencias en el grupo MDL. Conclusiones Esta serie de casos plantea la posibilidad de que, en pacientes seleccionados, el uso de IntraSPINE® pueda reducir el dolor de espalda y reducir las tasas de recurrencia de hernia de disco y las cirugías de revisión en la microdiscectomía lumbar. Se debe considerar un estudio prospectivo y aleatorizado del uso de IntraSPINE®, dadas las implicaciones clínicas y el costo de la cirugía de revisión. Nivel de Evidencia IV; Serie de casos.

ABSTRACT

BACKGROUND: Previous studies have reported what patients value while choosing their surgeon, but there are no studies exploring the patterns of referral to spine surgeons among primary care physicians (PCPs). This study aims to identify any trends in PCPs' referral to orthopedic surgery versus neurosurgery for spinal pathology.METHODS: In total, 450 internal medicine, family medicine, emergency medicine, neurology, and pain management physicians who practice at one of three locations (suburban community hospital, urban academic university hospital, and urban private practice) were asked to participate in the study. Consenting physicians completed our 24-question survey addressing their beliefs according to pathologies, locations of pathologies, and surgical interventions.RESULTS: Overall, 108 physicians (24%) completed our survey. Fifty-seven physicians (52.8%) felt that neurosurgeons would provide better long-term comprehensive spinal care. Overall, 66.7% of physicians would refer to neurosurgery for cervical spine radiculopathy; 52.8%, to neurosurgery for thoracic spine radiculopathy; and 56.5%, to orthopedics for lumbar spine radiculopathy. Most physicians would refer all spine fractures to orthopedics for treatment except cervical spine fractures (56.5% to neurosurgeons). Most physicians would refer to neurosurgery for extradural tumors (91.7%) and intradural tumors (96.3%). Most would refer to orthopedic surgeons for chronic pain. Finally, physicians would refer to orthopedics for spine fusion (61.1%) and discectomy (58.3%) and to neurosurgery for minimally invasive surgery (59.3%).CONCLUSIONS: Even though both orthopedic surgeons and neurosurgeons are intensively trained to treat a similar breath of spinal pathology, physicians vary in their referring patterns according to spinal pathology, location of pathology, and intended surgery. Education on the role of spine surgeons among PCPs is essential in ensuring unbiased referral patterns.

ABSTRACT

OBJECTIVE@#To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM).@*METHODS@#The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years. The patients were divided into ACDF group (group A, =17) and ACCF group (group B, =20) according to the different surgery. The operation time and intraoperative blood loss were recorded;the Cobb angle and cervical curvature in the cervical fusion segments before surgery and 1, 12 months after surgery were observed;Japanese Orthopaedic Association (JOA) score was used to evaluate the surgical efficacy, and the postoperative complications were analyzed.@*RESULTS@#All patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time and intraoperative blood loss in group A were (106.3±22.6) min, (52.2±26.4) ml, respectively, while were (115.6±16.8) min, ( 61.7±20.7) ml in group B. There was no statistically significant in operation time between two groups(>0.05);intraoperative blood loss in group B was larger than group A(0.05). At the final follow up, in group A, dysphagia occurred in 2 cases, cage displacement in 1 case, and no titanium plate screw loose was found;and in group B, dysphagia occurred in 4 cases, titanium mesh collapse in 2 cases, titanium plate screw loose in 1 case.@*CONCLUSION@#Two types of anterior cervical decompression and fusion for the treatment of two segment cervical spondylotic myelopathy can effectively decompress and improve the Cobb angle and cervical curvature of the affected vertebra. The ACDF surgical procedure can directly removethe compressive thing at intervertebral level, which will lead to little vertebral body damage and favorably recovered cervical curvature. The ACCF surgical procedure has a large operation space, which can easily remove the posterior vertebral osteophyte and the calcified posterior longitudinal ligament. Long-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.

ABSTRACT

OBJECTIVE@#To explore the clinical efficacy and safety of posterior intervertebral foraminal discectomy via Delta channel for cervical spondylotic radiculopathy in the early phase.@*METHODS@#From September 2017 to July 2018, 10 patients with cervical spondylotic radiculopathy underwent posterior intervertebral foraminal discectomy via Delta channel. There were 6 males and 4 females, aged from 30 to 62 years old with an average of (41.5±4.3) years old. All of them had unilateral symptoms caused by cervical nerve root compression, including 2 cases of C, 5 cases of C and 3 cases of C. CT and MRI examination of all the patients did not show ossification of posterior longitudinal ligament or calcification of ligamentum flavum, and no cervical spine instability was present in dynamic radiographs. The clinical outcome was poor after more than 6 weeks of systematic non-surgical treatment. The VAS score, JOA score, NDI score, the cervical spine physiological curvature, and the height and stability of the compressed cervical vertebrae were measured before operation and at the latest follow-up.@*RESULTS@#All patients successfully completed the surgeries without any spinal cord, nerve root or major blood vessel injury. The operation time was 70 to 120 min with an average of 90 min. Intraoperative blood loss ranged from 30 to 90 ml with an average of 40 ml. All the 10 patients were followed up for 6 to 14 months with an average of 9 months. Postoperative nerve root pain got relievd and nerve function was improved in all patients. VAS score decreased from 7.15±2.01 before surgery to 1.59±0.83 at the latest follow-up;JOA score increased from 12.57±1.24 before surgery to 16.42±0.58 at the latest follow-up;NDI score increased from 41.82±4.71 before surgery to 9.59±3.52 at the latest follow-up. All the results above presented significant difference between latest follow-up and preoperative (0.05). At the latest follow-up, no cervical instability was observed on dynamic radiographs.@*CONCLUSION@#Treatment of cervical spondylotic radiculopathy by posterior intervertebral foraminal discectomy via Delta channel can obtain a satisfactory clinical outcome without affecting the stability of cervical vertebra. The surgery is safe, reliable and worthy of clinical application.

ABSTRACT

OBJECTIVE@#To explore clinical efficacy of percutaneous endoscopic lumbar discectomy through two different approaches in treating upper lumbar disc herniation.@*METHODS@#From March 2015 to August 2019, 32 patients with upper lumbar disc herniation treated by percutaneous endoscopic lumbar dicecromy(PELD) were analyzed retrospectively and divided into percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) group according to different methods. There were 19 patients in PETD group, including 10 males and 9 females aged from 30 to 65 years old with an average of (44.70±12.08) years old;5 patients on L, 6 patients on L, 8 patients on L;6 patients were central herniation, 8 patients were paracentric herniation, and 5 patients were migration of herniation. There were 13 patients in PEID group, including 4 males and 9 females aged from 25 to 55 years old with an average of (42.23±12.09) years old;the courses of disease ranged from 1 to 7 months with an average of (2.90±3.02) months;3 patients on L, 4 patients on L, 6 patients on L;2 patients were central herniation, 4 patients were paracentric herniation, 3 patients were migration of herniation, 4 patients were prolapse free type protrusion. VAS and ODI score before operation, postoperative at 3 days, 3 and 6 months were compared between two groups, advanced MacNab standard at 1 year after operation were applied to evaluate clinical effects.@*RESULTS@#Operation were successful operated in 32 patients and obtained following up without nerve injury and infection of intervertebral space. One patient in PETD groups occurred dural sac tear in operation, but no adverse reaction afteroperation. PETD group was followed up from 12 to 24 months with an average of (15.80±3.48) months, while PEID group was followed up from 12 to 30 months with an average of (16.70±4.66) months, while there was no statistical difference between two groups (>0.05). VAS and ODI score at different time points after operation were higher than that of before operation (<0.05). According to advanced MacNab standard at 1 year after operation, 11 patients obtained excellent results, 6 good, 1 moderate and 1 poor in PETD group;while 7 patients got excellent results, 4 good, 2 moderate in PEID group.@*CONCLUSION@#Both of two surgical approach could achieve satisfactory efficacy in treating upper lumbar disc herniation, PETD is more suitable for central herniation, paracentric herniation and patients with mild displacement, PEID has advantage on prolapse free type protrusion.

ABSTRACT

RESUMEN Las alteraciones degenerativas de la columna se engloban en el término de espondilosis cervical. La mielopatía espondilótica cervical (MEC) es la forma más común de disfunción del cordón espinal en mayores de 55 años. Se considera la intervención quirúrgica en la mayoría de los casos de mielopatía cervical espondilótica evidente desde el punto de vista clínico, dado el riesgo de deterioro neurológico. En la mayoría de los casos de mielopatía cervical, la descompresión de la médula espinal genera estabilización o mejoría de la función de los haces largos medulares. La función es mejor cuando se restablecen bien las dimensiones del conducto vertebral después de la descompresión, cuando la descompresión es más precoz y cuando no hay comorbilidad considerable.


ABSTRACT The degenerative alterations of the column are included in the term of cervical espondilosis. The cervical spondylotic myelopathy it is the form more common of disfuntion of the spinal cord in bigger than 55 years. It is considered the surgical intervention in most of the cases of cervical spondylotic myelopathy evident from the clinical, given point of view the risk of neurological deterioration. In most of the cases of cervical myelopathy, the decompression of the spinal marrow generates stabilization or improvement of the function of the medullary long sheaves. The function is better when they recover well the dimensions of the vertebral conduit after the decompression, when the decompression is more precocious and when there is not considerable comorbility.

ABSTRACT

ABSTRACT Objective: This study aims to compare the use of halo-gravity traction (HGT) with and without previous anterior release, in terms of curve reduction, for the treatment of pediatric severe spinal deformity. Methods: From 2010 to 2016, all patients treated with HGT prior to instrumentation for scoliosis and kyphoscoliosis were reviewed. They were assessed by deformity etiology, previous anterior release, instrumentation procedure used, traction protocol, major Cobb angle before traction, after the protocol, and after the instrumentation procedure. Twelve patients met these criteria and constituted the sample groups: Group I (n=7) with anterior release and Group II (n=5) without anterior release. Results: The average pre-traction major curve Cobb angles were 114.9o and 108.4º for Group I and II, respectively (P>0.05). After HGT, both groups achieved a significant reduction in curve angle (P<0.05). Group I presented an average Cobb angle of 95.0o after HGT, representing a 17.3% (19.8o) curve reduction. Group II presented a Cobb angle of 80.1o, representing a 25.2% (28.4o) curve reduction. The difference between the two groups in relation to the reduction of major curve after HGT was not statistically significant (P=0.073). After the surgical procedure, the correction achieved was significantly improved (P<0.05), without statistically significant difference between the two groups (P>0.05). No major HGT related complications were reported. Conclusions: Anterior release prior to HGT did not increase major curve correction after posterior surgery for severe pediatric idiopathic and syndromic scoliosis. HGT is an effective and safe technique, though it frequently presents minor and transitory complications. Level of Evidence III; Retrospective Comparative Study.


RESUMO Objetivo: O presente estudo tem como objectivo comparar a utilização de tracção halo-gravitacional (THG), com e sem libertações anteriores prévias, no que diz respeito à correcção da curva no tratamento de escoliose grave pediátrica. Métodos: Foram avaliados retrospectivamente doentes com escoliose/cifoescoliose, tratados com THG prévia ao procedimento instrumentado, entre 2010 e 2016. Foi avaliada a etiologia da deformidade, realização de libertações discais prévias, tipo de procedimento instrumentado, protocolo da THG, ângulo de Cobb da curva major previamente à THG, após protocolo e após procedimento instrumentado. Doze doentes satisfaziam os critérios de inclusão: Grupo I (n=7) com libertações anteriores prévias e Grupo II (n=5) sem libertações prévias. Resultados: O ângulo Cobb médio da curva major era 114,9o e 108,4º para o Grupo I e II respectivamente (P>0,05). Após THG, ambos os grupos apresentaram redução significativa da curva major (P<0,05). O Grupo I apresentava um ângulo Cobb médio de 95,0o, representando redução de 17,3% (19,8o). O Grupo II apresentava um ângulo Cobb médio de 80,1o, representando redução de 25,2% (28,4o). Após THG não existiu diferença significativa entre os grupos, no que diz respeito à redução da curva major (P=0,073). Após instrumentação, a correcção aumentou de forma significativa (P<0,05), sem diferença estatisticamente significativa entre os dois grupos (P=0.05). Não existiram complicações major relacionadas com a THG. Conclusões: Libertações discais prévias à THG não parecem aumentar a correcção final da curva major, no tratamento de escoliose pediátrica grave. A THG é um método efectivo e seguro. Nível de Evidência III; Estudo Retrospectivo Comparativo.


RESUMEN Objetivo: Este estudio tiene como objetivo comparar el uso de la tracción de halo-gravedad (THG) con y sin liberación anterior previa, con respecto a la reducción de la curva en el tratamiento de la deformidad espinal pediátrica grave. Métodos: Entre 2010 y 2016, se revisaron todos los pacientes tratados con THG antes de la instrumentación para escoliosis y cifoescoliosis. Se evaluaron por etiología de la deformidad, liberación anterior previa, tipo de instrumentación, protocolo de tracción, ángulo de Cobb mayor antes de la tracción, después del protocolo y después de la instrumentación. Doce pacientes cumplieron los criterios de inclusión y constituyeron los grupos de muestra: Grupo I (n = 7) con liberación anterior y Grupo II (n = 5) sin liberación anterior. Resultados: El promedio de los ángulos de Cobb de la curva principal antes de la tracción fue de 114,9o y 108,4° para el grupo I y II, respectivamente (P > 0,05). Después de la THG, ambos grupos lograron una reducción significativa en el ángulo de la curva (P > 0,05). El Grupo I tenía ángulo Cobb promedio de 95o, después de la THG, lo que representa una reducción de la curva del 17,3% (19,8o). El Grupo II tenía ángulo de Cobb de 80,1º, que representa una reducción de la curva del 25,2% (28,4o). La diferencia entre los dos grupos en relación con la reducción de la curva principal después de la THG no fue estadísticamente significativa (P = 0.073). Después del procedimiento quirúrgico, la corrección mejoró de manera expresiva (P > 0,05), aunque sin diferencia estadísticamente significativa entre los dos grupos (P > 0,05). No se informaron complicaciones mayores relacionadas con la THG. Conclusiones: La liberación anterior previa a la THG no aumentó la corrección de la curva principal después de la cirugía posterior para la escoliosis pediátrica idiopática y sindrómica grave. La THG es una técnica efectiva y segura, aunque con frecuencia presenta complicaciones menores y transitorias. Nivel de Evidencia III; Estudio Retrospectivo Comparativo.
