RESUMO

Las fracturas del maléolo posterior están presentes en 7-44% del total de fracturas de tobillo.El objetivo de esta revisión es conocer la evidencia actual sobre las indicaciones de fijación interna y la elección del abordaje quirúrgico para el tratamiento de estas fracturas.Las indicaciones clásicas de fijación eran el tamaño mayor a 25-30% de la superficie articular y el desplazamiento mayor a 2 mm; sin embargo, la evidencia actual sugiere que, en lugar del tamaño, se deben considerar factores tales como la inestabilidad sindesmal, el escalón articular mayor a 1-2 mm, la impactación de la superficie articular y la presencia de fragmentos intercalares.Al comparar las vías de abordaje, la bibliografía apoya el uso de los abordajes posteriores, reservando la recomendación de abordaje anterior para casos excepcionales.Para el tratamiento de esta lesión es fundamental conocer la anatomía del tobillo y considerar los factores descritos, además de la presencia de lesiones concomitantes.(AU)


Posterior malleolus fractures are frequent injuries, present in 7–44% of all ankle fractures.The objective of this study is to review the evidence to indicate the fixation of this fracture and to choose the appropriate surgical approach.The classic indications for fixation were fragment size greater than 25–30% of the articular surface and displacement greater than 2 mm. However, current evidence suggests that, rather than size, factors such as syndesmotic instability, intra-articular step-off greater than 1–2 mm, plafond impaction and the presence of intercalary fragments should be considered.When comparing the different surgical approaches, the literature supports the use of posterior approaches and reserves the recommendation of the traditional approach for exceptional cases.For the treatment of this injury it is essential to know the anatomy of the ankle and to consider all the factors described above, in addition to the presence of concomitant injuries.(AU)

RESUMO

Introducción: Existe una gran controversia con respecto a la existencia de un abordaje quirúrgico óptimo para artroplastia de cadera. El énfasis actual en la investigación ha sido examinar las posibles diferencias en los resultados funcionales entre el abordaje anterior y el abordaje posterior. Objetivo: Comparar las medidas de resultado informadas por los pacientes sometidos a artroplastia total de cadera, mediante abordajes anterior y posterior. Métodos: Se realiza una búsqueda sobre el tema en la base de datos PubMed entre los años 2010-2020 en inglés con los términos: comparación entre abordaje anterior y abordaje posterior de la cadera, abordaje anterior directo de la cadera, abordaje posterior de la cadera, y resultados de artroplastia de la cadera mediante abordajes anterior y posterior. Análisis y síntesis de la información: El abordaje anterior muestra una mayor mejora en la velocidad de la marcha, la longitud del paso y la simetría de la marcha, en comparación con el abordaje posterior para artroplastia de cadera al mes después de la operación. A los cuatro meses estas características de la marcha no fueron diferentes, pero los resultados de algunas pruebas funcionales fueron superiores en los pacientes intervenidos por abordaje anterior. Conclusiones: La elección del abordaje quirúrgico para artroplastia de cadera debe basarse en los factores del paciente, la preferencia del cirujano y su experiencia(AU)


Introduction: There is great controversy regarding the existence of an optimal surgical approach for hip arthroplasty. The current research emphasis has been to examine the possible differences in functional outcomes between anterior and posterior approaches. Objective: To compare the outcome measures reported by patients undergoing total hip arthroplasty, using anterior and posterior approaches. Methods: A search is carried out on the subject in the PubMed database during the years 2010-2020, in English, with the terms comparison between anterior approach and posterior approach to the hip, direct anterior approach to the hip, posterior approach to the hip, and results of hip arthroplasty using anterior and posterior approaches. Analysis and synthesis of the information: The anterior approach showed greater improvement in gait speed, stride length and gait symmetry, compared to the posterior approach for hip arthroplasty one month after the operation. At four months, these gait characteristics were not different, but the results of some functional tests were superior in patients operated on by anterior approach. Conclusions: The choice of the surgical approach for hip arthroplasty should be based on the patient´s factors, preference of the surgeons and their experience(AU)

RESUMO

OBJETIVO: Comparar la eficiencia de las cuatro técnicas quirúrgicas más utilizadas para el manejo de la espondilitis tuberculosa. MÉTODO: Estudio retrospectivo en el que se incluyeron pacientes adultos con diagnóstico confirmado de espondilitis tuberculosa, afectación de dos niveles vertebrales o menos y sin deformidad vertebral grave. Se recopilaron y revisaron los expedientes médicos, los estudios de imagen y los datos demográficos de los pacientes intervenidos para analizar retrospectivamente los resultados clínicos y funcionales de cada grupo. Las variables primarias fueron la erradicación de la infección, la fusión vertebral y las complicaciones. Entre las variables secundarias se estudiaron el sangrado intraoperatorio, la estancia hospitalaria y el tiempo quirúrgico. RESULTADOS: Entre los grupos analizados no hubo diferencias significativas (p ≥ 0.05) en la mayoría de las variables analizadas, pero sí (p ≤ 0.001) respecto al sangrado, el tiempo quirúrgico, la estancia intrahospitalaria y las complicaciones, a favor del abordaje posterior único. CONCLUSIONES: El abordaje posterior único logró una eficacia clínica similar a la del resto de los abordajes en términos de erradicación de la infección y fusión vertebral; sin embargo, se asoció a menores tiempo quirúrgico, sangrado, estancia hospitalaria y complicaciones. OBJECTIVE: To compare the efficiency of the 4 most used surgical techniques for the management of tuberculous spondylitis. METHOD: Retrospective study in which adult patients with a confirmed diagnosis of tuberculous spondylitis, involvement of two vertebral levels or less, and without severe vertebral deformity were included. The medical records, imaging studies, and demographic data of the operated patients were collected and reviewed to retrospectively analyze the clinical results of each group. The primary variables were cure of infection, spinal fusion, and complications. The secondary variables included intraoperative bleeding, hospital stay, and surgical time. RESULTS: There were no significant differences (p ≥ 0.05) in most of the variables analyzed, however, there were (p ≤ 0.001) regarding bleeding, surgical time, hospital stay and complications between the groups analyzed, with a lower result in all cases for the single posterior approach. CONCLUSIONS: The single posterior approach obtained a clinical efficacy similar to the rest of the approaches in terms of eradication of the infection and vertebral fusion, however, it was associated with less surgical invasion (surgical time and bleeding), a shorter hospital stay and complications.

RESUMO

Introducción: El abordaje retroperitoneoscópico posterior es una técnica poco extendida en España para la suprarrenalectomía a pesar de que, según algunos autores, ofrece ventajas respecto al acceso laparoscópico anterior o lateral. El objetivo del estudio fue identificar aquellas características que permitieran seleccionar los casos más favorables para iniciarse en esta técnica. Métodos: Estudio observacional de una cohorte de 50 pacientes intervenidos mediante suprarrenalectomía retroperitoneoscópica posterior (SRP) en un único centro. Se evaluó: sexo, edad e índice de masa corporal (IMC), tiempo operatorio, lateralidad, tamaño y características anatomopatológicas de las lesiones, tasa de conversión, complicaciones y estancia hospitalaria. Resultados: Se intervinieron 25 (50%) mujeres y 25 (50%) hombres con un tiempo operatorio mediano de 80 minutos (45-180). Se observó un tiempo operatorio significativamente menor en mujeres (p = 0,002) y en adenomas (p = 0,002). En cambio, no se observó correlación entre el tiempo quirúrgico e IMC, lateralidad o tamaño de la lesión. No hubo ningún caso de conversión. Las complicaciones fueron del 14% y la mayoría fueron leves, según la Escala de Clavien Dindo (i). La estancia hospitalaria mediana fue de dos días. Conclusiones: La suprarrenalectomía retroperitoneoscópica por vía posterior es una técnica segura, reproducible y con muy buenos resultados. Los casos más favorables para iniciar la implantación de este abordaje son mujeres con adenomas suprarrenales. (AU)


Introduction: The posterior retroperitoneoscopic approach (PRA) is seldom used in our country to perform adrenalectomies, although it offers possible advantages over laparoscopic anterior or lateral access, according to some authors. The aim of this study was to identify those features that determine the most suitable cases to start the implementation of this technique. Methods: A prospective observational study was performed with a 50 patients cohort. All the cases were operated using the PRA. Sex, age, body mass index (BMI), operative time, left or right side, size and anatomopathological characteristics of the lesion, conversion rates, complications and hospital stay were analyzed. Results: 25 (50%) women and 25 (50%) men underwent surgery, with a median operative time of 80 minutes (45-180). A significantly shorter operative time (p = 0.002) was observed in women and in adenomas (p = 0.002). However, no correlation was observed between surgical time and BMI, lesion side or lesion size. There were no conversions. The complication rate was 14%, and most of the complications were grade i in Clavien Dindo's Scale. Median hospital stay was two days. Conclusions: Retroperitoneoscopic adrenalectomy by posterior approach is a safe and reproducible procedure, with very good outcomes. The most suitable cases to implement this technique would be female patients with adrenal adenomas. (AU)

RESUMO

BACKGROUND AND OBJECTIVES: There is no current consensus on the most suitable hip approach. However, there is a trend to reduce damage to soft tissue, which may have an influence on early outcomes. The SuperPath approach accesses the capsule maintaining integrity of the external rotators. The purpose of this study was to compare the SuperPath approach with the conventional posterior approach, in terms of early outcomes and radiological results. MATERIAL AND METHODS: A cohort of 30 patients operated using the SuperPath approach was prospectively matched for age, gender, body mass index and hip function with 60 patients operated using a conventional posterior approach. Clinical evaluation was performed by the Harris score, Merle d'Aubigné score, reduced Western Ontario and McMasters Universities (WOMAC), Short-Form 12 (SF12), IHOT-ADV and IHOT-12 questionnaires. Radiological evaluation was also performed. RESULTS: Preoperatively, no significant differences were detected between cohorts. Skin-to-skin operation time and blood loss was higher in the SuperPath cohort. Length of stay was similar between cohorts. Clinical evaluation improved significantly from the preoperative values to the 1-year follow-up. At 3 months the SuperPath cohort showed better results for IHOT-12, and at 12 months for SF. Radiologically, there were no differences between cohorts. CONCLUSION: This prospective randomized study reveals that the learning curve for the SuperPath approach provides similar outcomes to the conventional posterior approach within the first year after surgery. The Superpath approach was associated with longer skin-to-skin operation time, and greater blood loss.

RESUMO

We report a case of a 41 years old patient complaining of chronic dorsalgia. MRI showed a well defined intradural extramedular dumbbell-shaped lesion, associated to a left paravertebral tumor at D5-D6 level. The tumor was embolizated prior to surgery. Following she underwent a D4-D6 laminotomy, left D5-D6 costotransversectomy and resection of the intracanal extradural part of the lesion with section of the left D5 nerve. Posteriorly, complete resection of the extracanal portion of the tumor was performed by a postero-lateral approach. The anatomopathologic diagnosis was a malignant schwannoma. After the surgery, the patient required adyuvant radiotherapic treatment. Malignant schwannoma is a very uncommon tumor which belongs to the malignant peripheral nerve sheath tumors (MPNST). It develops from Schwann cells. It is frequently associated with type 1 neurofibromatosis. MPNST usually present local recurrence and can metastatize.

RESUMO

OBJECTIVE: To determine the incidence of dislocation after primary total hip arthroplasty using a posterior approach with repair of capsule and transosseous external rotators. MATERIAL AND METHOD: Historical cohort study between January 2009 and December 2015 of all the cases of dislocation of primary total hip arthroplasty operated using a posterior approach with repair of capsule and transosseous external rotators. Demographic and clinical data concerning the patient, surgery and dislocation were collected and analyzed. A descriptive analysis and a study of survival and risk function were performed by Kaplan Meier's method considering the appearance of a hip dislocation as the final event. RESULTS: The incidence of dislocation in our study was 1.2% (23 patients). In our study, the highest probability of dislocation occurred in the first 120 days. Forty-three point 5percent of the dislocated patients needed revision surgery. CONCLUSIONS: Capsular repair and transosseous reattachment of the external rotators can help to reduce the incidence of dislocation in patients undergoing primary total hip arthroplasty through a posterior approach.

RESUMO

Las fracturas de platillos tibiales son lesiones complejas que incluyen una variedad de patrones morfológicos cada vez mejor caracterizados en la literatura. Históricamente, los esquemas de clasificación se han basado en evaluar los rasgos de fractura en el plano frontal y las técnicas quirúrgicas en lograr la fijación de esos fragmentos, sin tomar en consideración el compromiso óseo que ocurre en la región posterior de los platillos tibiales. Con el advenimiento de la clasificación columnar basada en tomografía computada, se han logrado desarrollar estrategias de fijación optimizada, dando cada vez más relevancia a la columna posterior. Este artículo realiza una revisión extensa de la literatura, otorgando los fundamentos quirúrgicos que explican la importancia del tratamiento específico de la columna posterolateral y posteromedial, con el fin de restablecer la biomecánica normal de la rodilla y el razonamiento quirúrgico de las diversas vías de abordaje específicas para una reducción y osteosíntesis satisfactoria de esos fragmentos.


Tibial plateau fractures are complex injuries which include a variety of morphological patterns that have been increasingly better characterized in the literature. Historically, classifications have focused on description of fracture patterns in the frontal plane, while surgical techniques have focused on reduction of these fragments not considering the osseous defects that occur on the posterior region of the tibial plateau. With new CT scan column based classifications, strategies to optimize fixation have been developed, giving relevance to the posterior column. This article is an exhaustive review of the literature, providing the surgical foundations that explain the importance of specific treatment of the posterolateral and posteromedial column, aiming to restore normal knee biomechanics. Furthermore, this article provides the diverse specific surgical approaches rationale for a satisfactory open reduction and internal fixation of these fragments.

RESUMO

Introducción Las fracturas de húmero diafisarias corresponden al 3-5% de las fracturas en general. La distribución de las fracturas que comprometen el tercio distal de la diáfisis es variable con incidencias estimadas entre el 10 y el 48%. El objetivo del estudio es evaluar los resultados funcionales y la tasa de consolidación de un grupo de pacientes con fractura diafisaria de húmero del tercio distal con técnica mínimamente invasiva por vía posterior. Materiales y métodos Entre 2013 y 2016 se intervino a 23 pacientes, con una media de edad de 36 años. La valoración funcional se realizó por medio de la Escala de Discapacidades del Hombro, el Codo y la Mano (DASH) abreviada y la medición de los arcos de movilidad de hombro y codo con goniometría; el dolor fue evaluado de acuerdo con la Escala Visual Análoga del Dolor (EVA). Resultados Todas las fracturas consolidaron de forma exitosa, excepto dos casos que presentaron retardo en la consolidación. La lesión del nervio radial previa a la intervención se recuperó de forma progresiva sin requerimiento de transferencias. Los resultados funcionales fueron satisfactorios en un grupo de diez pacientes que completaron más de 1 año de seguimiento. Discusión El abordaje posterior de humero con mínima invasión en el tratamiento de este patrón particular de fracturas parece que muestra una ventaja biológica al permitir una consolidación completa en todos los pacientes. La lesión del nervio radial iatrogénica no parece que aumente en relación con su aislamiento y protección en la porción proximal del tríceps. Nivel de evidencia clínica Nivel IV.


Background Diaphyseal humeral fractures correspond to 3-5% of all fractures. The proportion of these fractures in which the distal third of the diaphysis is involved is variable with estimated incidences between 10-48%. The aim of the study is to evaluate the functional results and rate of fracture consolidation for a group of patients with distal third diaphyseal humeral fractures managed using a minimally invasive technique through a posterior approach. Materials and methods Twenty-two patients (mean age of 36 years) were evaluated between 2013 and 2016. Functional assessment was performed using the DASH abbreviated functional scale. Shoulder and elbow mobility range of motion were measured with goniometry, and pain was measured following the VAS scale. Results All fractures consolidated successfully, with two cases exhibiting delay in consolidation. Radial nerve injury prior to the intervention was progressively recovered without the need for supplementary tendons transfers. Functional results were satisfactory for ten patients that completed more than one year of follow-up. Discussion Minimally invasive technique with posterior approach in the treatment of this particular pattern of humeral fractures seems to show a biological advantage in allowing complete consolidation in all patients. Iatrogenic radial nerve injury does not appear to increase in relation to its isolation and protection in the proximal portion of the triceps. Evidence level IV.

RESUMO

PURPOSE: To evaluate the clinical and radiological outcomes of these fractures treated through a modified posterior approach with a distal humerus plate. MATERIAL AND METHODS: Between 2013 and 2015 we performed a retrospective study of these fractures surgically treated in our centre. INCLUSION CRITERIA: older than 18 years old, no pathological fractures, follow up 1 year at least. 23 patients underwent surgery, mean age 45 years old, with an average follow-up of 18 months. Patient characteristics, aetiology and type of fractures were recorded. The surgery was performed using Gerwin modified posterior approach with a posterolateral distal humerus plate. Clinical results were evaluated using Quick DASH, MEPS, VAS. Radiological results were also evaluated. Complications associated with treatment and radial nerve palsy incidence were recorded as well. RESULTS: Type of fracture according AO/OTA: six 12-A, seven 12-B, ten 12-C. 23 patients progressed to union. After one year: QD 6.43, VAS 0.66, MEPS 88.88. No failure of internal fixation. Two superficial infections. 15 excellent results, 5 good, and 3 fair, with no poor results. CONCLUSION: Surgical fixation of these fractures through a modified posterior approach with a posterolateral plate minimises iatrogenic nerve injury, provides better visualisation of the proximal humerus, provides stable fixation of these injuries and results in high union rates and overall excellent functional results.

RESUMO

Introducción: El balance sagital es crítico para los resultados a largo plazo en el manejo quirúrgico de la escoliosis idiopática del adolescente. La cifosis de unión se podría definir como un hallazgo radiológico en la transición de la columna fusionada y la columna móvil en pacientes asintomáticos. El objetivo de este trabajo fue comparar la cifosis de unión proximal posoperatoria en curvas Lenke 5C con dos técnicas quirúrgicas distintas: la instrumentación anterior y la instrumentación posterior. Materiales y Métodos: Estudio retrospectivo, controlado no aleatorizado, de 37 pacientes con escoliosis idiopática del adolescente, curvas Lenke 5C con fusión corta, de vértebra límite a vértebra límite. Grupo 1: 18 pacientes con artrodesis anterior instrumentada y Grupo 2: 19 pacientes con artrodesis posterior instrumentada. Los parámetros sagitales radiológicos medidos fueron: 1) línea de plomada de C7, 2) cifosis de unión, 3) cifosis torácica, 4) lordosis lumbar, con un seguimiento mínimo de 2 años. Resultados: Grupo 1: aumento de la cifosis de unión entre el preoperatorio y el seguimiento a los 2 años de 6,27° (p = 0,0002). La incidencia de cifosis de unión patológica fue del 17 por ciento. Grupo 2: aumento de la cifosis de unión entre el preoperatorio y el seguimiento de 4,63° (p = 0,0004). La incidencia de cifosis de unión patológica fue del 16 por ciento. Conclusión: No hubo diferencias significativas entre ambos grupos en la incidencia de cifosis de unión patológica.


Background: Sagittal balance is critical for long-term results in the surgical handling of adolescent idiopathic scoliosis. Proximal junctional kyphosis could be defined as a radiographic findings in the fused and mobile spine transition in asymptomatic patients. Objective: To compare post-surgical proximal junctional kyphosis in Lenke C5 curves with two different surgical techniques: anterior and posterior instrumentation. Methods: Retrospective, controlled, non-randomized study of 37 patients with Lenke C5 adolescent idiopathic scoliosis, with short fusion from end-vertebra to end-vertebra. Group 1: 18 patients with anterior instrumented arthrodesis, and Group 2: 19 patients with posterior instrumented arthrodesis. The radiographic sagittal parameters measured were: 1) plumbline from the C7, 2) junctional kyphosis, 3) thoracic kyphosis, and 4) lumbar lordosis; with a minimum follow-up of two years. Results: Group 1: increase of junctional kyphosis between the preoperative period and a two-year follow-up, 6.27° (p = 0.0002). The incidence of pathologic junctional kyphosis was 17%. Group 2: increase of junctional kyphosis between the preoperative period and the follow- up, 4.63° (p = 0.0004). The incidence of pathologic junctional kyphosis was 16%. Conclusion: There were no significant differences between groups in the incidence of pathologic junctional kyphosis.

RESUMO

Introducción: El balance sagital es crítico para los resultados a largo plazo en el manejo quirúrgico de la escoliosis idiopática del adolescente. La cifosis de unión se podría definir como un hallazgo radiológico en la transición de la columna fusionada y la columna móvil en pacientes asintomáticos. El objetivo de este trabajo fue comparar la cifosis de unión proximal posoperatoria en curvas Lenke 5C con dos técnicas quirúrgicas distintas: la instrumentación anterior y la instrumentación posterior. Materiales y Métodos: Estudio retrospectivo, controlado no aleatorizado, de 37 pacientes con escoliosis idiopática del adolescente, curvas Lenke 5C con fusión corta, de vértebra límite a vértebra límite. Grupo 1: 18 pacientes con artrodesis anterior instrumentada y Grupo 2: 19 pacientes con artrodesis posterior instrumentada. Los parámetros sagitales radiológicos medidos fueron: 1) línea de plomada de C7, 2) cifosis de unión, 3) cifosis torácica, 4) lordosis lumbar, con un seguimiento mínimo de 2 años. Resultados: Grupo 1: aumento de la cifosis de unión entre el preoperatorio y el seguimiento a los 2 años de 6,27° (p = 0,0002). La incidencia de cifosis de unión patológica fue del 17 por ciento. Grupo 2: aumento de la cifosis de unión entre el preoperatorio y el seguimiento de 4,63° (p = 0,0004). La incidencia de cifosis de unión patológica fue del 16 por ciento. Conclusión: No hubo diferencias significativas entre ambos grupos en la incidencia de cifosis de unión patológica. (AU)


Background: Sagittal balance is critical for long-term results in the surgical handling of adolescent idiopathic scoliosis. Proximal junctional kyphosis could be defined as a radiographic findings in the fused and mobile spine transition in asymptomatic patients. Objective: To compare post-surgical proximal junctional kyphosis in Lenke C5 curves with two different surgical techniques: anterior and posterior instrumentation. Methods: Retrospective, controlled, non-randomized study of 37 patients with Lenke C5 adolescent idiopathic scoliosis, with short fusion from end-vertebra to end-vertebra. Group 1: 18 patients with anterior instrumented arthrodesis, and Group 2: 19 patients with posterior instrumented arthrodesis. The radiographic sagittal parameters measured were: 1) plumbline from the C7, 2) junctional kyphosis, 3) thoracic kyphosis, and 4) lumbar lordosis; with a minimum follow-up of two years. Results: Group 1: increase of junctional kyphosis between the preoperative period and a two-year follow-up, 6.27° (p = 0.0002). The incidence of pathologic junctional kyphosis was 17%. Group 2: increase of junctional kyphosis between the preoperative period and the follow- up, 4.63° (p = 0.0004). The incidence of pathologic junctional kyphosis was 16%. Conclusion: There were no significant differences between groups in the incidence of pathologic junctional kyphosis. (AU)
