Tendencias temporales pasadas y proyectadas en la cirugía artroscópica de cadera en España entre 1998 y 2018 / Past and projected temporal trends in arthroscopic hip surgery in Spain between 1998 and 2018

Objetivo: Describir la incidencia poblacional de la artroscopia de cadera desde 1998 hasta 2018 y proyectar las tendencias para el año 2030, así como describir las variaciones en la incidencia poblacional entre las comunidades autónomas (CC. AA.). Material y método: Se realizó una revisión retrospectiva del conjunto mínimo básico de datos de 1998-2018. Se analizó su evolución temporal y se identificaron las variables asociadas con la indicación (edad, sexo, CC. AA.). Por cada comunidad autónoma se calculó la tasa cruda por 100.000 habitantes. Se realizó la proyección 2019-2030 para España mediante regresión lineal. Resultados: En España entre 1998 y 2018 se realizaron un total de 10.663 CAC. La incidencia poblacional en 1998 era de 0,14 CAC por cada 100.000 habitantes, mientras que para el 2018 era de 4,09. Con respecto a 2018, para el año 2030 se espera un incremento de 156,9% en el número de CAC (p<0,001). En promedio las CAC en hombres representaron el 57,7% (IC 95%: 55,2-60,2) de todos los procedimientos y la mayor incidencia se encontró en edades≤44 años. La variación geográfica es del 81%, siendo la diferencia de incidencia por 100.000 habitantes de hasta 15,4 veces entre algunas CC. AA. Conclusiones: El número de artroscopias de cadera en España ha ido en aumento en el periodo 1998-2018, y se prevé que esta tendencia creciente continúe hasta el año 2030. En España los procedimientos artroscópicos de cadera se realizan con más frecuencia en pacientes hombres y en menores de 45 años. La variabilidad de la incidencia poblacional entre las CC. AA. es alta.(AU)

Objective: Describe the population incidence of hip arthroscopy from 1998 to 2018 and to project the trends for the year 2030, as well as to describe the variations in the population incidence between the autonomous communities. Material and method: A retrospective review of the minimum basic data set from 1998 to 2018 was carried out. Temporal evolution was analyzed and the variables associated with the indication (age, sex, regions) were identified. For each region, the crude rate per 100,000 inhabitants was calculated. The 2019–2030 projection was made using linear regression. Results: In Spain between 1998 and 2018 a total of 10,663 arthroscopic hip surgeries were carried out. The population incidence in 1998 was 0.14 CAC per 100,000 inhabitants, while in 2018 it was 4.09. For the year 2030 an increase of 156.9% in the number of arthroscopic hip surgeries is expected (P<.001). On average, 57.7% of all procedures (95% CI 55.2–60.2) were done in men and the highest incidence was found in ages ≤44 years. The geographical variation was 81%, being up to 15.4 times the difference in incidence per 100,000 inhabitants between some regions. Conclusions:The number of hip arthroscopies in Spain has been increasing in the 1998–2018 period and this growing trend is expected to continue until 2030. In Spain, hip arthroscopic procedures are performed more frequently in male patients and in under 45 years old. The variability of the population incidence between the autonomous communities is high.(AU)

Consenso Internacional sobre Tromboembolismo Venoso (ICM-VTE) en COT, cambiará en algo nuestra práctica clínica? / International Consensus Meeting on Venous Thromboembolism (ICM-VTE) after orthopedic procedures, any change in our clinical practice?

Las aportaciones del Consenso Internacional sobre Tromboembolismo Venoso (ICM-VTE) modificarán nuestra práctica diaria, recogiendo la evidencia actual que no aparece en la mayoría de las guías de práctica clínica hasta la fecha. Muchos de nuestros procedimientos de cirugía ortopédica y traumatología no requieren de una profilaxis tromboembólica que solo se administra cuando existen factores de riesgos individuales o cirugías mayores (artroplastia total de miembros inferiores, cirugía de columna o fracturas que requieran inmovilización y limitación en la carga precoz). Dentro de las opciones de profilaxis debemos tener en cuenta la potencia del fármaco para prevenir el tromboembolismo venoso, pero también el efecto de hemorragia y sangrado que pueda producir. El uso de aspirina y medidas mecánicas se establece como la combinación más segura y eficaz en muchos de los casos.(AU)

The International Consensus Meeting on Venous Thromboembolism (ICM-VTE), will change our current practice as most recent evidence is included. This fact is not usual in most clinical practice guidelines to date. Many orthopedic and trauma procedures do not require thromboembolic prophylaxis, but it should be considered depending on individual risk factors or major surgeries (total hip or knee arthroplasty, spine surgery or fractures that require immobilization and weight bearing restriction). Within the prophylaxis options, we must notice the strengh of the drug preventing venous thromboembolism, but also the effect of hemorrhage and bleeding that it may produce. The use of aspirin and mechanical prophylaxis has been described as the safest and most effective combination in most cases.(AU)

[Scientific and research activity and degree of satisfaction of residents of Orthopedic Surgery and Traumatology in different hospitals of the health network in Spain]. / Actividad científica e investigadora y grado de satisfacción de residentes de Cirugía Ortopédica y Traumatología en diferentes hospitales de la red sanitaria en España.

INTRODUCTION: Healthcare pressure has changed the acquisition of knowledge during residency training. The aim of this study was to analyze the clinical and research training, and level of satisfaction, during orthopedic and traumatology residency in different hospitals of the Spanish National Health Service. MATERIAL AND METHODS: An online survey was distributed between 06/25/2020 and 07/31/2020. Demographic, institution, clinical and research variables were analyzed. Satisfaction was graded in a scale from 0 to 5. RESULTS: 120 residents answered the survey, having a mean age of 27 years and being 58% male. Distribution of residents by year was 26 R5 (21.7%), 24 R4 (20.0%), 45 R3 (37.5%), 25 R2 (20.9%). Only 37.5% answered that they did not have any clinical activity the next day after medical guard, and 45% answered that they performed clinical activity outside of working hours. A total of 56.7% answered that their orthopedic training program did not include research training. No resident had specific time assigned to research activities. Mean satisfaction value was 2.4 points. CONCLUSIONS: Clinical activity shows aspects incompatible with current legislation. Orthopedic programs need improvements with regard to research training. A significant percentage of residents are unsatisfied with their training.

INTRODUCCIÓN: La presión asistencial ha provocado un desequilibrio hacia la vertiente clínica con respecto a la científica. El propósito del trabajo fue analizar la actividad asistencial e investigadora y el grado de satisfacción en los residentes de cirugía ortopédica y traumatología, en diferentes hospitales de la red sanitaria en España. MATERIAL Y MÉTODOS: Encuesta de ámbito estatal realizada en el período del 25/06/2020 al 31/07/2020. Se analizaron variables demográficas y del servicio, de labores asistencial e investigadora. Se determinó la satisfacción del residente en escala continua de cero a 5. RESULTADOS: 120 médicos haciendo residencia respondieron a la encuesta, rondando una edad media de 27 años y predominio de varones en 58%. La distribución por año de dichos residentes fue de 26 R5 (21.7%), 24 R4 (20.0%), 45 R3 (37.5%), 25 R2 (20.9%). Sólo 37.5% indicaron carecer de labor de tipo asistencial asignada el día siguiente de la guardia y 45% respondieron que realizaban algún papel asistencial fuera del horario laboral del hospital. De esos interrogados, 56.7% contestaron que su plan individual de formación no contemplaba la praxis científica ajustada a su año de residencia como un objetivo a cumplir. Ninguno de ellos tenía tiempo asignado con periodicidad semanal para acciones de investigación. El valor medio del nivel de satisfacción de estos médicos fue de 2.4 puntos. CONCLUSIONES: La actividad asistencial presenta aspectos incompatibles con la legislación actual. Los planes individuales de adiestramiento precisan mejoras con respecto a la ocupación investigadora. Un porcentaje no despreciable de estos estudiantes de posgrado no estaban satisfechos con su plan personal de especialización.

Embolismo gaseoso tras el uso del sistema de lavado CarboJet® durante la hemiartroplastía de cadera: Caso clínico y revisión de la literatura / Gas embolism after the use of the CarboJet® lavage system during hip hemiarthroplasty: Clinical case and literature review

Presentamos el caso de una paciente de 89 años de edad que sufrió paro cardiorrespiratorio durante la realización de hemiartroplastía de cadera cementada que precisó resucitación cardiopulmonar. Esta complicación ocurrió inmediatamente después de usar el sistema de lavado mediante dióxido de carbono CarboJet®, y se atribuyó a embolismo gaseoso, tras descartar otras entidades. Se discuten los posibles factores que pueden contribuir a esta complicación quirúrgica.

Case report of an 89 year-old patient who had cardiorespiratory arrest during cemented hip hemiarthroplasty and required cardiopulmonary resuscitation. This complication occurred immediately after using the carbon dioxide-based lavage system known as CarboJet® and was attributed to gas embolism once other entities were ruled out. The possible factors that may contribute to this surgical complication are discussed.

The relevance of the radiological signs of acetabular retroversion among patients with femoroacetabular impingement.

Orthopaedic surgeons have accepted various radiological signs to be representative of acetabular retroversion, which is the main characteristic of focal over-coverage in patients with femoroacetabular impingement (FAI). Using a validated method for radiological analysis, we assessed the relevance of these signs to predict intra-articular lesions in 93 patients undergoing surgery for FAI. A logistic regression model to predict chondral damage showed that an acetabular retroversion index (ARI) > 20%, a derivative of the well-known cross-over sign, was an independent predictor (p = 0.036). However, ARI was less significant than the Tönnis classification (p = 0.019) and age (p = 0.031) in the same model. ARI was unable to discriminate between grades of chondral lesions, while the type of cam lesion (p = 0.004) and age (p = 0.047) were able to. Other widely recognised signs of acetabular retroversion, such as the ischial spine sign, the posterior wall sign or the cross-over sign were irrelevant according to our analysis. Regardless of its secondary predictive role, an ARI > 20% appears to be the most clinically relevant radiological sign of acetabular retroversion in symptomatic patients with FAI.

Evaluación mediante navegación intraoperatoria de la laxitud del ligamento cruzado anterior en su reconstrucción anatómica monofascicular / Evaluation of intraoperative anterior cruciate ligament laxity using a navigation system in the anatomical single bundle reconstruction

Objetivo. La técnica de reconstrucción anatómica del ligamento cruzado anterior (LCA) persigue, reproduciendo la orientación nativa de sus fibras, alcanzar una mejor estabilidad rotacional en la rodilla. El objetivo principal del presente trabajo es la evaluación cuantitativa intraoperatoria, mediante el uso del sistema de navegación de Orthopilot®, de la laxitud anteroposterior y rotacional de la rodilla antes y después de una ligamentoplastia anatómica. Material y método. Descripción de la técnica de navegación y estudio transversal sobre una cohorte de 20 pacientes intervenidos en nuestro centro por rotura primaria crónica del LCA desde enero de 2010 hasta mayo de 2011. Con la ayuda del navegador se definió la posición exacta de los túneles en base a referencias anatómicas intraarticulares y se realizaron pruebas de estabilidad, tanto en el plano sagital como en el axial. Resultados. Nuestra técnica de reconstrucción anatómica del LCA situó el túnel tibial a una distancia media de 16,8±4,92 mm del ligamento cruzado posterior y a un 44,1%±4,35% de la anchura total del platillo tibial. La distancia media del centro del túnel femoral a la cortical posterior del cóndilo lateral fue de 7,89±2,78 mm. Intraoperatoriamente y antes de la reconstrucción, los valores medios (±DE) de traslación anteroposterior, rotación interna y rotación externa de la tibia a 30° fueron de 15,5mm (±5,11); 19° (±3,62) y 19,65° (±3,26) respectivamente. Tras la reconstrucción dichos valores disminuyeron a 5,6mm (±1,72); 12,17° (±3,76) y 16,9° (±4,42). Conclusiones. El empleo de sistemas de navegación como apoyo al cirujano permite sistematizar la posición de los túneles óseos y estandarizar el procedimiento en relación a la reconstrucción deseada. La reconstrucción del LCA según la técnica descrita, mejora la estabilidad anteroposterior y rotacional monoplanar respecto al estado preoperatorio pudiendo restablecer los valores de laxitud a los considerados como fisiológicos acorde al conocimiento científico actual (AU)

Purpose. The anatomical anterior cruciate ligament (ACL) reconstruction attempts to, by reproducing the natural orientation of its fibres, achieve a better rotational stability of the knee. The aim of this paper is to quantify the anteroposterior and rotational laxity of the knee before and after an anatomic ligamentoplasty using the Orthopilot® navigation system as a supporting tool. Matherial and method. We describe the distinctive steps of Orthopilot® navigation as well as conducting a retrospective cross-sectional study on a cohort of 20 patients operated in our hospital for chronic primary ACL rupture from january 2010 to may 2011. The precise location of the tunnels was defined with the help of the navigator and the intra-articular landmarks and stability tests were performed in both the sagittal and axial planes. Results. In our technique for anatomical ACL reconstruction placed the tibial tunnel at a mean distance of 16.8±4.92mm from the posterior cruciate ligament in a position that represented 44.1%±4.35 of the total width of the tibial plateau. The average distance from the centre of the femoral tunnel to the posterior cortex of the lateral condyle was 7.89±2.78mm. Intra-operatively and before ACL reconstruction, the mean (±SD) anteroposterior movement, internal rotation and external rotation of the tibia at 30° position were 15.5mm (±5.11), 19° (±3.62) and 19.65° (±3.26), respectively. After reconstruction these values decreased to 5.6mm (±1.72°), 12.17° (±3.76) and 16.9° (±4.42), respectively. Conclusions. The use of navigation systems supporting the surgery allows the systematic positioning of bone tunnels and standardises the procedures for the desired reconstruction. ACL reconstruction using the technique described, improves the anteroposterior and rotational stability compared to preoperative status, to a stability state that could be considered physiological according to current scientific knowledge (AU)

After reconstruction these values decreased to 5.6 mm (±1.72°), 12.17° (±3.76) and 16.9° (±4.42), respectively. CONCLUSIONS: The use of navigation systems supporting the surgery allows the systematic positioning of bone tunnels and standardises the procedures for the desired reconstruction. ACL reconstruction using the technique described, improves the anteroposterior and rotational stability compared to preoperative status, to a stability state that could be considered physiological according to current scientific knowledge.

Medicina Basada en la Evidencia y su aplicación a la cirugía ortopédica y traumatología / Evidence-based medicine and its application in trauma and orthopaedic surgery

Hoy en día no se concibe el ejercicio de la medicina sino es bajo las formas de medicina basada en la evidencia. Esta búsqueda sistemática de la mejor evidencia posible a la hora de tomar decisiones clínicas requiere de una metódica bien conocida. A través de este artículo los autores exponen los fundamentos de la medicina basada en la evidencia para acercar al autor , empleando un ejemplo real, a los aspectos mas prácticos de la misma (AU)

Today is inconceivable medical practice without the forms of evidence-based medicine. This systematic search for the best available evidence when making clinical decisions requires a well-known methods. Through this article the authors explain the basics of evidence-based medicine to bring the author, using a real example, the more practical aspects of it (AU)

Hip osteoplasty by an anterior minimally invasive approach for active patients with femoroacetabular impingement.

Femoroacetabular regularization in hip impingement is currently performed by means of trochanter osteotomy and hip dislocation or more recently by means of hip arthroscopy. We present a novel alternative through a unique mini-invasive anterior approach. Our first series consisted of 35 hips (32 patients) with a mean follow-up of 29.2 months. Range of motion (ROM) and clinical scores were evaluated preoperatively at six weeks, three months, six months and one-year follow-up (FU). Impingement test was negative in 33 out of 35 cases six weeks after surgery. Mean hospitalisation time was 2.6 days (2-5 days). Mean improvement in internal rotation was 23 degrees (p=0.006) and 21 degrees in flexion (p=0.011). There was a significant improvement in hip score according to the Merle d'Aubign evaluation (13.8 points preoperative vs. 16.9 at one-year visit) (p=0.017). No Trendelenburg, heterotopic calcifications or osteonecrosis were observed. Complications related to the femorocutaneous nerve appeared in six cases (17.1%) although all but one were neuroapraxia and disappeared before one year. Mean rehabilitation time was 4.4 weeks. We conclude that the anterior surgical approach for the treatment of femoroacetabular impingement enables early resumption of sport while accuracy in bone resection is maintained.

Afectación de la potencia extensora comparando el abordaje medial frente al abordaje transrotuliano en la revisión de artroplastia de rodilla / Medial versus transpatellar approach in TKR: differences in the resulting involvement of knee extensor mechanism strength

Objetivo. Valorar la potencia de aparato extensor en la revisión de artroplastia total de rodilla (ATR) entre el abordaje parapatelar medial y el abordaje con osteotomía rotuliana. Material y método. Se realiza un estudio retrospectivo sobre 22 pacientes. El seguimiento medio fue 24,6 meses y edad media 70,2 años. Resultados. Existe un déficit mayor en la potencia extensora con la vía transrotuliana (22,3%) frente a la vía parapatelar medial (12,3%). Con la vía parapatelar aparecieron dos casos de avulsión parcial del tendón rotuliano y un caso de necrosis cutánea. Presentaron molestias femoropatelares 4 pacientes en el abordaje parapatelar medial y 4 casos con la vía transrotuliana. Existió falta de unión de la osteotomía en dos casos y seudoartrosis fibrosa en 3 pacientes. Conclusiones. Existe una disminución de la potencia extensora en el abordaje transrotuliano con menores complicaciones sobre el aparato extensor. Este abordaje podría considerarse en casos especialmente complejos de revisión protésica de rodilla

Purpose. To compare the repercussion of total knee arthroplasty (TKR) on knee extensor strength when performed through a medial parapatellar approach vs. a patellar osteotomy. Materials and methods. This is a retrospective study that included 22 patients. Mean follow-up was 24.6 months and mean age 70.2 years. Results. There is a greater deficit in the knee extensor mechanism when the transpatellar approach is performed (22.3%) vs. the medial parapatellar approach (12.3%). With the parapatellar approach, there were two cases of a partial avulsion of the patellar tendon and one case of skin necrosis. Four patients had patellofemoral discomfort with the medial parapatellar approach and another four with the transpatellar one. There were two cases of non-union of the osteotomy and three cases of fibrous pseudoarthrosis. Conclusions. There is a reduction in knee extensor strength with the transpatellar approach with fewer complications for the extensor mechanism. This approach could be considered in specially complex cases of TKR
