El papel de la cirugía mínimamente invasiva de columna en el tratamiento de las metástasis vertebrales (parte 1): una revisión clínica / The role of minimally invasive spine surgery in the treatment of vertebral metastasis (part 1): A clinical review

Las metástasis espinales representan una importante carga sobre la calidad de vida en los pacientes afectados por una enfermedad oncológica activa, debido a la alta incidencia de síndromes dolorosos, deformidad espinal y deterioro neurológico. La cirugía juega un papel determinante a la hora de mejorar la calidad de vida mediante el control del dolor, el restablecimiento de la función neurológica y el mantenimiento de la estabilidad espinal, además de contribuir a la respuesta de la terapia médica. La cirugía mínimamente invasiva (MIS) es una opción de tratamiento en determinados pacientes con alto riesgo quirúrgico, ya que tiene una baja tasa de complicaciones, de sangrado intraoperatorio, de estancia hospitalaria y ofrece resultados similares a la cirugía abierta. Presentamos en esta revisión el papel de la MIS en esta enfermedad, y algunos casos tratados en nuestro centro hospitalario.(AU)

Spinal metastases represent a significant burden on the quality of life in patients affected by active oncological disease due to the high incidence of pain syndromes, spinal deformity, and neurological impairment. Surgery plays a decisive role in improving quality of life by controlling pain, restoring neurological function and maintaining spinal stability, as well as contributing to the response to medical therapy. Minimally invasive surgery (MIS) is a treatment option in certain patients with high surgical risk since it has a low rate of complications, intraoperative bleeding, hospital stay, and offers similar results to open surgery. In this review, we present the role of MIS in this pathology and some cases treated in our hospital.(AU)

[Impact of COVID-19 pandemic confinement on musculoskeletal pain and quality of life]. / Impacto del confinamiento por la pandemia COVID-19 en el dolor musculoesquelético y la calidad de vida.

INTRODUCTION: in March 2020, lockdown was established in Spain because of the COVID-19 pandemic. The aim of this study is to assess its impact on pain and quality of life in patients with musculoskeletal pain. MATERIAL AND METHODS: prospective study including 490 individuals grouped in: 140 people without pain, 140 people with musculoskeletal pain but without any related pathology diagnosed, 140 patients diagnosed for a musculoskeletal condition and 70 patients in surgical waiting list (SWL) for a musculoskeletal condition. Data regarding pain, physical activity and quality of life (EuroQol-5D) was collected at the beginning of lockdown and one year after (March 2021). RESULTS: mean age was 53 ± 17.5 years old (18-88) and 51.3% were women. Patients in SWL referred significantly more pain than the rest of groups (p < 0.001), with a score in the visual analogue scale of 6.3 ± 1.9. Groups 3 and 4 suffered a significant increase of their pain from 2020 to 2021 (p < 0.001), while decreasing in group 2 (p < 0.001). Analgesics intake grew from 2020 to 2021 (39.9% versus 44.3%, p = 0.007). 70.2% experienced a worsening of at least one dimension of EuroQol-5D over last year, with patients in SWL being the most affected (p < 0.001). CONCLUSION: lockdown has caused in patients with musculoskeletal conditions a greater aggravation of pain and deterioration of quality of life than in the general population, especially in patients in SWL, translating in an increase in analgesics intake.

INTRODUCCIÓN: en Marzo de 2020 se estableció el confinamiento en España debido a la pandemia por COVID-19. El objetivo de este estudio es determinar su impacto en el dolor y la calidad de vida de personas con dolor osteomuscular. MATERIAL Y MÉTODOS: estudio prospectivo que incluyó 490 personas agrupadas en: 140 personas sin dolor (grupo 1), 140 personas con dolor osteomuscular, pero sin patología diagnosticada (grupo 2), 140 pacientes con patología musculoesquelética (grupo 3) y 70 pacientes en lista de espera quirúrgica (LEQ) por patología musculoesquelética (grupo 4). Se recogieron datos sobre el dolor, la actividad física y la calidad de vida (EuroQol-5D) al inicio del confinamiento y un año después. RESULTADOS: la edad media fue de 53 ± 17.5 años (18-88) y 51.3% fueron mujeres. Las personas en LEQ refirieron un dolor significativamente mayor que el resto de grupos (p < 0.001) con una puntuación en la escala visual analógica del dolor de 6.3 ± 1.9. Los grupos 3 y 4 sufrieron un aumento significativo de su dolor desde 2020 hasta 2021 (p < 0.001), mientras que en el grupo 2 disminuyó (p < 0.001). El consumo de analgésicos creció de 2020 a 2021 (39.9% versus 44.3%, p = 0.007); 70.2% sufrió un empeoramiento en alguna de las dimensiones del EuroQol-5D, siendo el grupo en LEQ el más afectado (p < 0.001). CONCLUSIONES: el confinamiento ha producido en pacientes con patología musculoesquelética un empeoramiento del dolor y de calidad de vida mayor que en el resto de personas, especialmente en aquéllas en espera de cirugía, traduciéndose en un aumento del consumo de analgésicos.

[Lateral osteotomy of the calcaneus in the treatment of Müller-Weiss disease]. / Osteotomía lateral de calcáneo en el tratamiento de la enfermedad de Müller-Weiss.

INTRODUCTION: The deforming condition of the navicular bone known as Müller-Weiss disease (MWD) is a rare disease. Patients present with chronic pain in the talonavicular joint and a paradoxical flat foot with a varo hindfoot. OBJECTIVE: To analyze the clinical results of a lateral osteotomy of calcaneus applied to patients with MWD. MATERIAL AND METHODS: Retrospective observational study carried out in two hospitals. The series consists of nine cases in eight patients, all of them with symptomatic Müller-Weiss disease, treated by lateral osteotomy of the calcaneus between 2012 and 2017, obtaining an average follow-up of 4 years (2-6). The mean age was 62 years (50-75). In all patients, Costa-Bartani angles (CB), Kite angle and Calcaneal Inclination (CI) were measured. In addition, the Manchester Oxford Scale (MO) to measure the post-surgical satisfaction of patients. RESULTS: All patients report having improved their pain by obtaining a postoperative score on the mean Manchester Oxford scale of 32.54 points (15.62-53.75). In 66% of patients the CB angle improves, the Kite angle in 89% and the CI in 33%. CONCLUSION: The improvement in the pain of the patients in our series is not accompanied by radiological changes in the same proportion, it is a simple and uncomplicated technique in our follow-up.

INTRODUCCIÓN: La afección deformante del hueso navicular conocida como enfermedad de Müller-Weiss (EMW) es una enfermedad rara. Los pacientes presentan dolor crónico en la articulación talonavicular y un pie plano paradójico con retropié varo. OBJETIVO: Analizar los resultados clínicos de la osteotomía valguizante de calcáneo aplicada a pacientes con EMW. MATERIAL Y MÉTODOS: Estudio observacional, retrospectivo, realizado en dos centros hospitalarios. La serie consta de nueve casos en ocho pacientes, todos ellos con enfermedad de Müller-Weiss sintomática, fueron tratados mediante osteotomía valguizante de calcáneo entre 2012 y 2017, con un seguimiento medio de cuatro años (dos a seis). La edad media fue de 62 años (50-75). En todos los pacientes se midieron los ángulos de Costa-Bartani (CB), el ángulo de Kite y la inclinación calcánea (IC). Además, se utilizó la escala Manchester Oxford (MO) para medir la satisfacción postquirúrgica de los pacientes. RESULTADOS: Todos los pacientes refieren haber mejorado en su dolor, obteniendo una puntuación postoperatoria media de 32.54 puntos (15.62-53.75) en la escala Manchester Oxford. En 66% de los pacientes el ángulo CB mejoró, al igual que en el ángulo de Kite en 89% y la IC en 33%. CONCLUSIÓN: La mejoría en el dolor de los pacientes de nuestra serie no está acompañada por cambios radiológicos en la misma proporción, es una técnica sencilla y sin complicaciones en nuestro seguimiento.

Arteriovenograma de cemento óseo en artroplastia de cadera / Cement arteriovenogram after hip arthroplasty

Las altas presiones intramedulares que se alcanzan durante la cementación en la artroplastia de cadera pueden producir la extrusión de este cemento hacia los vasos nutricios femorales, generando una imagen radiográfica característica (arteriovenograma de cemento o cementograma). Presentamos una serie de 14 casos de pacientes intervenidos mediante artroplastia de cadera cementada en los que se observó un cementograma como hallazgo postoperatorio. Ninguno de estos pacientes sufrió complicaciones locales o sistémicas tras la cementación ni durante un seguimiento medio de 3 años. El cementograma es un hallazgo radiográfico postoperatorio que da cuenta de una buena presurización del cemento durante la cirugía y que no se asocia a complicaciones médicas ni a fracturas alrededor del implante femoral

Modern cement implantation techniques during hip arthroplasty rely on high intramedullary pressures which can result in cement extrusion towards femoral nutrient vessels, and thus, the occurrence of a particular image in postoperative radiographs (bone cement arterio-venogram). We report a case series of 14 patients in whom a bone cement arterio-venogram was observed after undergoing a cemented hip arthroplasty. No local or systemic complications developed after cementing nor during a mean follow-up of three years. Bone cement arterio-venogram is a radiologic sign that indicates a good cement pressurisation during surgery and is not associated to medical complications or periprosthetic femoral fractures

Desarrollo de una calculadora para establecer indicación de derivación a consulta de cirugía del raquis en patología degenerativa lumbar / Development of a calculator to establish indications to refer patients with lumbar degenerative disease for spinal surgery consultation

ANTECEDENTES Y OBJETIVO: Hoy por hoy el dolor lumbar sigue constituyendo una entidad patológica de alta incidencia en la población occidental. No hemos encontrado en la literatura datos que evalúen si con una exploración física correcta y una valoración de las radiologías simples de la columna vertebral se puede diagnosticar a los pacientes con una alta probabilidad de ser candidatos a cirugía de columna lumbar, disminuyendo así la carga asistencial y el consumo de recursos que esta patología supone. El objetivo del estudio es desarrollar una calculadora de fácil manejo que permita derivar a las consultas de Cirugía del Raquis solo a los pacientes con elevada probabilidad de recibir tratamiento quirúrgico. MATERIALES Y MÉTODOS: Estudio observacional y retrospectivo que incluyó a todos los pacientes mayores de edad del Área Sanitaria de Talavera de la Reina (Toledo) con diagnóstico clínico y/o radiológico de patología lumbar degenerativa derivados, por otros especialistas durante un año natural, a la unidad de Cirugía de Columna para valorar la indicación de cirugía tras tratamiento conservador infructuoso. Todos los pacientes fueron evaluados bajo un mismo protocolo con un seguimiento de 6años, al final de los cuales se controló quiénes fueron intervenidos sobre la columna lumbar. RESULTADOS: Se estudiaron un total de 201 pacientes, y al final de los 6años de seguimiento se intervinieron un total de 77 pacientes. Se encontró una concordancia del 70% entre la indicación de tratamiento quirúrgico y el tratamiento recibido al final del seguimiento, por lo que se realizó una regresión logística tratando de hacer una predicción de los pacientes que se pueden derivar a las unidades de Cirugía del Raquis, y a partir de ahí se generó una calculadora, que incluía la variable radiología simple como ítem imprescindible, y que mostró como estadísticamente significativo (p < 0,05): la edad, los signos de no organicidad de Waddell, el signo de Lassegue y la valoración de la radiología simple. A partir de la obtención de esta herramienta, se realizó el cálculo de probabilidad de ser intervenido a todos los pacientes a los que se propuso tratamiento quirúrgico, obteniéndose como punto de corte, al emplear la calculadora, unos resultados por encima del 62%. CONCLUSIONES: El empleo de la calculadora diseñada predice la posibilidad de ser candidato a tratamiento quirúrgico con un 70% de fiabilidad, así que los pacientes con un resultado en la calculadora superior al 62% deben ser derivados a consultas de Cirugía del Raquis para valoración por un especialista

BACKGROUND AND AIM: Low-back pain remains a common pathological entity in the Western population. We have found no data in the literature that assess whether, with correct physical examination and evaluation of simple x-rays of the spine, it is possible to diagnose patients who are highly likely to be candidates for lumbar spine surgery and thus reduce the care burden and resource consumption that this disorder entails. The aim of the study was to develop a user-friendly calculator that allows only patients who are strong candidates for surgical treatment to be referred for spinal surgery consultation. MATERIAL AND METHOD: An observational and retrospective study that included all adult patients from the healthcare area of Talavera de la Reina (Toledo, Spain) with a clinical and/or radiological diagnosis of degenerative lumbar spine disease referred by other specialists over one calendar year to the spinal surgery unit to assess whether surgery was indicated after unsuccessful conservative treatment. All the patients were assessed under the same protocol with a follow-up of 6years, at the end of which we performed a check of those who had undergone lumber spine surgery. RESULTS: A total of 201 patients were studied and at the end of the 6-year follow-up, a total of 77 patients had been operated. Concordance of 70% was found between the indication for surgical treatment and the treatment received at the end of the follow-up. Therefore a logistic regression was performed in an attempt to predict the patients that could be referred to the spinal surgery units and from that a calculator was generated, which included the plain x-ray variable as an essential item, and which showed as statistically significant (P<.05): age, Waddell's non-organic signs, Lasegue's sign and plain x-ray assessment. Once this tool had been obtained, the likelihood of undergoing surgery was calculated for all patients who were proposed surgical treatment, obtaining results above 62% as the cut-off point when using the calculator. CONCLUSIONS: The use of the calculator predicts the possibility of being a candidate for surgical treatment with 70% reliability. Therefore, patients with a result in the calculator of above 62% should be referred for spinal surgery consultation for assessment by a specialist

Management of pediatric tibial tubercle fractures: Is surgical treatment really necessary?

Fractures of the anterior tibial tubercle are infrequent lesions. They often occur in male adolescent athletes, usually in relation with sports involving powerful jumps. We present a retrospective study of 10 patients, with an average age of 15.1 years, all of them males, and a total of 11 acute avulsions of the anterior tibial tubercle. We analyzed the etiology of the lesion, the type of treatment used as well as non-weight bearing period, protected immobilization period, and time until sports reincorporation. We obtained 11 acute avulsions: one case of type I; three cases of type II; four cases of type III; and three cases of type IV. Five cases were treated conservatively, including the three cases of type IV, and surgery was only performed in six cases since an anatomical reduction was not obtained with closed reduction. The results were satisfactory in all cases, with 100% percentage of sport reincorporation in less de 25 weeks. We registered only one complication, intolerance of material, which did not require additional surgeries. These fractures, although rare, have an excellent prognosis. Even if they are often treated surgically, we have obtained good results with the conservative treatment in patterns previously reported as surgical.

Quiste óseo aneurismático localizado en el techo acetabular en un varón de 11 años / Aneurysmal bone cyst located on the acetabular roof in an 11-year-old male

Resumen: El quiste óseo aneurismático es una tumoración benigna poco común, de aparición en la infancia generalmente y a nivel de extremidades. El tratamiento más habitual consiste en el curetaje y relleno con injerto. No obstante, localizaciones poco accesibles a la cirugía suponen un reto terapéutico. Se presenta el caso de un paciente de 11 años con cojera y dolor en cadera derecha sin antecedente traumático ni infeccioso. En los estudios de imagen con TAC y RM se evidencia una lesión lítica expansiva que ocupa todo el techo del acetábulo y pala ilíaca derecha, sugestiva de un quiste óseo aneurismático presentando fractura acetabular asociada. Se realizó una biopsia que confirmó el diagnóstico. Se trató mediante embolización guiada por angiografía debido al gran volumen y alto riesgo de fractura, después del curetaje y relleno con aloinjerto evolucionó satisfactoriamente y el paciente se encuentra asintomático al año de la intervención.

Abstract: The aneurysmal bone cyst is a benign rare tumor, which usually develops during childhood and it's more often found in limbs. The most accepted treatment consists in curetagge and filling with graft. However, certain locations may be inaccesible for surgery and represent therapeutical challenges. We present the case of an 11 year-old male patient with limping and right hip pain without any traumatic nor infectious record. In the image studies with CT and MRI a lytic and expansive lession was found in the upper part of the right acetabulum and right iliac wing, all of which suggested an aneurysmal bone cyst with an associated acetabular fracture. A biopsy was performed which confirmed the diagnosis. He was treated with a CT-guided embolization and, due to its size, curetagge and allograft filling afterwards. He was asymptomatic after1 year of follow-up.

Artrodesis intersomática lumbar extralateral. Técnica quirúrgica, resultados y complicaciones con un seguimiento mínimo de un año / Extreme lateral lumbar interbody fusion. Surgical technique, outcomes and complications after a minimum of one year follow-up

Durante los últimos años se han desarrollado técnicas «mínimamente invasivas» de artrodesis que pretenden alcanzar los buenos resultados clínicos con una baja incidencia de complicaciones. La artrodesis intersomática extralateral o directa transpsoas es una artrodesis anterior mínimamente invasiva. Se han intervenido desde mayo de 2012 hasta mayo de 2015, un total de 97 pacientes con 138 segmentos intervenidos. El seguimiento fue de 44 a 12 meses. La edad media fue de 68 años (41-86). La causa más frecuente de intervención fue el segmento adyacente (30%), la deformidad (22%) y la discopatía lumbar (21%). La caja intersomática se implantó: sola («stand-alone»), en el 33% y se utilizó fijación adicional en el resto: tornillos percutáneos unilaterales (11%), bilaterales (27%) o con placa lateral (62%). La estancia media fue 3,2 días (2-6). La puntuación de la escala analógica visual lumbar pasó de 9 a 4,1 bajando a 3 a partir del año. La mejoría de la altura del disco fue de 8,4mm a 13,8mm y un aumento del diámetro mayor del foramen de 10,5 a 13,1. Dichas diferencias son estadísticamente significativas. Se registraron complicaciones precoces mayores: tres lesiones motoras del nervio femoral y un hematoma retroperitoneal (4%); y precoces menores: dos fracturas/hundimientos (2%). Como tardías mayores: una hernia abdominal, una movilización de 10mm y tres radiculopatías (5%); y como tardías menores: tres fracturas/hundimiento, dos movilizaciones mayores de 10mm, cuatro movilizaciones menores de 10mm y una movilización de un tornillo de una placa (10%). La técnica artrodesis intersomática extralateral constituye una alternativa segura y fiable a la hora de plantear una artrodesis lumbar por vía mínimamente invasiva (AU)

«Minimally invasive» techniques have been recently been developed in order to achieve good clinical results with a low incidence of complications. The extralateral interbody fusion or direct transpsoas is a minimally invasive anterior arthrodesis. A total of 97 patients with 138 segments received surgery between May 2012 and May 2015. The follow-up was from 12-44 months. The mean age was 68 years (41-86). The most common cause of intervention was the adjacent segment (30%), deformity (22%), and lumbar disc disease (21%). The interbody cage was implanted as: Single (stand-alone) in 33%, and additional fixation was used in the others: Screws, percutaneous unilateral (11%), bilateral (27%), or with a lateral plate (62%). The mean stay was 3.2 days (2-6). The score on a lumbar visual analogue scale decreased from 9 to 4.1, and dropped to 3 after one year. The improvement in disc height was from 8.4mm to 13.8mm, and a larger increase in the foramen diameter from 10.5 to 13.1mm, which were statistically significant. The early major complications recorded were, three motor femoral nerve injuries and retroperitoneal haematoma (4%), and the early minor were: two fractures (2%). As major late complications there was an abdominal hernia, a mobilization of 10mm and three radiculopathy (5%), and as minor late, three fracture, two mobilisations greater than 10mm, four mobilisations of less than 10mm, and one mobilisation of a screw plate (10%). The extralateral interbody fusion technique is a safe and reliable when performing a lumbar fusion by an alternative minimally invasive route (AU)

Análisis de sentencias judiciales relativas a negligencias médicas emitidas contra traumatólogos entre 1995 y 2011 / Analysis of judicial sentences issued against traumatologists between 1995 and 2011 as regards medical negligence

Introducción y objetivos. La Traumatología y Cirugía Ortopédica es una de las especialidades más reclamadas por su amplitud y complejidad. Nuestro objetivo es determinar las características de las reclamaciones presentadas contra médicos especialistas en Traumatología, considerando todas aquellas variables que puedan tener influencia tanto en el planteamiento de la demanda como en la resolución del proceso. Material y métodos. Se ha realizado un análisis de 303 sentencias judiciales (1995-2011) recogidas en el archivo de sentencias judiciales sanitarias de la Escuela de Medicina Legal de Madrid que se nutre de la base de datos de Westlaw Aranzazi. Resultados. La jurisdicción civil fue la más empleada. El proceso específico más reclamado fueron los trastornos osteoarticulares seguidos de las alteraciones vasculonerviosas y de las infecciones. La lesión reclamada ocurrió con más frecuencia en miembros inferiores sobre todo rodilla. La causa general de reclamación más frecuente fue el error terapéutico quirúrgico seguido del error diagnóstico. En el 14,9% fue el defecto de información. Existió condena en el 49,8% de los casos siendo la indemnización mayoritariamente menor de 50.000 euros. Conclusiones. Concluimos que la Traumatología y Cirugía Ortopédica es una especialidad proclive a las reclamaciones por mala praxis. El número de condenas a traumatólogos es elevado pero las indemnizaciones suelen ser menores de 50.000 euros. El motivo fundamental de las reclamaciones es el error terapéutico quirúrgico siendo pues el acto quirúrgico fundamental y donde se deben extremar las precauciones. Las condenas por deficiente información son elevadas siendo fundamental una adecuada comunicación médico-paciente y rellenar correctamente el consentimiento informado (AU)

Introduction and objectives. Traumatology and Orthopaedic Surgery is one of the specialities with most complaints due to its scope and complexity. The aim of this study is to determine the characteristics of the complaints made against medical specialists in Traumatology, taking into account those variables that might have an influence both on the presenting of the complaint as well as on the resolving of the process. Material and methods. An analysis was performed on 303 legal judgments (1995-2011) collected in the health legal judgements archive of the Madrid School of Medicine, which is linked to the Westlaw Aranzadi data base. Results. Civil jurisdiction was the most used. The specific processes with most complaints were bone-joint disorders followed by vascular-nerve problems and infections. The injury claimed against most was in the lower limb, particularly the knee. The most frequent general cause of complaint was surgical treatment error, followed by diagnostic error. There was lack of information in 14.9%. There was sentencing in 49.8% of the cases, with compensation mainly being less than 50,000 euros. Conclusions. Traumatology and Orthopaedic Surgery is a speciality prone to complaints due to malpractice. The number of sentences against traumatologists is high, but compensations are usually less than 50,000 euros. The main reason for sentencing is surgical treatment error; thus being the basic surgical procedure and where precautions should be maximised. The judgements due to lack of information are high, with adequate doctor-patient communication being essential as well as the correct completion of the informed consent (AU)

Factores asociados a la satisfacción del residente con su formación como especialista / Factors associated with residents’ satisfaction with their training as specialists

Antecedentes y objetivos: No se conoce qué factores influyen en la percepción de la satisfacción de los residentes durante su formación. El objetivo del estudio fue analizar la satisfacción del especialista en formación y sus factores asociados. Material y métodos: Estudio transversal mediante encuestas autocumplimentadas a los residentes en formación del Hospital Clínico San Carlos en los cortes realizados en los años 2006, 2009, 2010 y 2012. La variable dependiente del estudio fue la satisfacción global con la formación, y como factores independientes se estudiaron características sociodemográficas y laborales, variables relacionadas con la actividad asistencial, docente e investigadora. Resultados: Porcentaje de participación total de un 83,7% (1.424/1.701). La edad media fue 28,4 (DE 3,2) años. El porcentaje de satisfacción global fue de un 75,2%. En el análisis multivariado, los factores asociados de manera estadísticamente significativa a la satisfacción global fueron: la implicación del personal docente (tutores y adjuntos) en la formación, mayor satisfacción en especialidades médicas frente a las quirúrgicas, el año de residencia, las facilidades para realizar la tesis, trabajar menos de 40h a la semana, el tiempo adecuado para la realización de las tareas diarias, la adecuación en el número de sesiones en el servicio y el no disponer de otra especialidad previa. Conclusiones: Las actividades relacionadas con la investigación y docencia están asociadas con la satisfacción global del residente. Los factores de la actividad rutinaria que más se asocian con la satisfacción fueron el tiempo disponible y las horas de trabajo. Son necesarios más estudios para conocer el impacto de la satisfacción del residente en la calidad asistencial y en su actividad como futuro especialista (AU)

Background and objectives: We do not know what factors influence residents’ perceived satisfaction during their training. The aim of this study was to analyze the satisfaction of specialists with their training and its associated factors. Material and methods: This was a cross-sectional study using self-completion surveys of residents in training at the Clinic Hospital San Carlos for the courses conducted in 2006, 2009, 2010 and 2012. The study's dependent variable was overall satisfaction with the training; the independent factors were demographic and occupational characteristics, variables related to healthcare, teaching and research activity. Results: The total participation percentage was 83.7% (1,424/1,701), and the mean age was 28.4 years (SD, 3.2 years). The overall satisfaction percentage was 75.2%. The factors statistically associated with overall satisfaction in the multivariate analysis were the involvement of the teaching staff (tutors and assistants) in the training, greater satisfaction in medical versus surgical specialties, the year of residence, the facilities for completing the thesis, working less than 40h a week, adequate time to perform daily tasks, appropriate number of department meetings and not having a previous specialty. Conclusions: the activities related to research and teaching are associated with the overall satisfaction of residents. The routine activity factors most closely associated with satisfaction were the time available and the work hours. More studies are necessary to understand the impact of resident satisfaction on care quality and in their activity as future specialists (AU)
