[Avascular necrosis of the femoral head after COVID-19: clinical presentation and management. Clinical-functional outcomes of decompression and supplementation with bone marrow cell aspirate]. / Necrosis avascular de la cabeza femoral tras COVID-19: presentación clínica y manejo. Resultados clínico-funcionales de descompresión y suplementación con aspirado de células de médula ósea.

INTRODUCTION: the pandemic of COVID-19 has led to clinical complications such as avascular necrosis of the femoral head (AVNFH) associated with the use of corticosteroids. The aim of the study is to report the functional and radiographic results of 13 patients with post-COVID-19 ANFH after decompression using Forage and bone marrow aspirate concentrate (BMAC). MATERIAL AND METHODS: single-center, prospective, uncontrolled clinical study. From April 2020 to September 2021, 13 patients (21 hips) with post-COVID-19 ANFH were treated. All received corticosteroids during infection (average daily dose: 480 mg). Clinical, radiographic and magnetic resonance imaging evaluations were performed; the Ficat classification was applied for the classification of AVNFH. The surgical technique used was decompression with Forage and ACMO. RESULTS: the mean age was 47 years, with a follow-up of 30.4 months. Symptoms appeared with a mean of 4.2 months after COVID-19 infection. Harris score improved from 41.2 ± 5.2 to 86.6 ± 3.4. Radiographic evaluation showed that 14.3% of the sample experienced femoral head collapse and underwent total hip arthroplasty. CONCLUSIONS: post-COVID-19 ANFH is a clinical entity with rapid progression and different degrees of severity. Decompression with Forage and ACMO seems a promising initial treatment, however, the variable response and the probability of collapse emphasize the importance of long-term follow-up and identification of patients who may require additional interventions.

INTRODUCCIÓN: la pandemia de COVID-19 ha dado lugar a complicaciones clínicas como la necrosis avascular de la cabeza femoral (NAVCF) asociada con el uso de corticoesteroides. El objetivo del estudio es reportar los resultados funcionales y radiográficos de 13 pacientes con NAVCF post-COVID-19, después de la descompresión utilizando Forage y aspirado de células de medula ósea (ACMO). MATERIAL Y MÉTODOS: estudio clínico unicéntrico, prospectivo, no controlado. Desde Abril de 2020 hasta Septiembre de 2021, se trataron 13 pacientes (21 caderas) con NAVCF post-COVID-19. Todos recibieron corticoesteroides durante la infección (dosis promedio diaria: 480 mg). Se realizaron evaluaciones clínicas, radiográficas y por resonancia magnética nuclear; se aplicó la clasificación de Ficat para la clasificación de NAVCF. La técnica quirúrgica empleada fue descompresión con Forage y ACMO. RESULTADOS: la edad promedio fue 47 años, con un seguimiento de 30.4 meses. Los síntomas aparecieron con una media de 4.2 meses después de la infección por COVID-19. La escala de Harris mejoró de 41.2 ± 5.2 a 86.6 ± 3.4. La evaluación radiográfica demostró que 14.3% de la muestra experimentó colapso de la cabeza femoral por lo que se les realizó artroplastía total de cadera. CONCLUSIONES: la NAVCF post-COVID-19 es una entidad clínica con rápida progresión y diferentes grados de severidad. La descompresión con Forage y ACMO parece un tratamiento inicial prometedor; sin embargo, la respuesta variable y la probabilidad de colapso, enfatizan la importancia de seguimiento a largo plazo e identificación de los pacientes que puedan requerir intervenciones adicionales.

Early postoperative complications of thoracolumbar fractures in patients with multiple trauma according to the surgical timing / Complicaciones postoperatoriass de fracturas toracolumbares en pacientes con traumatismo múltiple según el momento de la cirugía

Introduction and objetctives: Our objective was to compare the rate of complications in thoracolumbar fractures that occurred during the early postoperative period in patients with multiple high-energy trauma according to the time of surgery. As a secondary objective, to estimate which variables were associated with surgery before 72h. Material and methods: Retrospective analysis of a series of patients with thoracolumbar fractures and multiple associated injuries in other anatomical regions due to high energy trauma. Surgically treated in an occupational trauma referral center, by the same surgical team and during the period between January 2013 and December 2019. Results: We analyzed a sample of 40 patients (39 men and 1 woman). The rate of complications was independent of surgical delay (before and after 72h) (p=0.827). There were statistically significant differences between early and later surgery groups in the variables age, systolic blood pressure, initial SOFA score and presence of neurological damage (p=0.014; p=0.029; p=0.032; p=0.012). The overall surgical delay was correlated with the SOFA score (p=0.007). Conclusion: The rate of early postoperative complications did not show significant differences between the early and late surgery groups. We observed that the patients who had been operated before 72h from trauma were younger, had more association with neurological syntoms, presented higher blood pressure values and less physiological damage. Surgical delay was positively correlated with SOFA score on arrival.(AU)

Introducción y objetivos: Nuestro objetivo es comparar la tasa de complicaciones acontecidas durante el postoperatorio temprano de fracturas toracolumbares en pacientes con traumatismos múltiples de alta energía según el momento de la cirugía. Como objetivo secundario, estimar qué variables se asociaron el desarrollo de la cirugía antes de las 72h. Materiales y métodos: Análisis retrospectivo de una serie de pacientes con fracturas toracolumbares y múltiples lesiones asociadas en otras regiones anatómicas por traumatismo de alta energía. Tratados quirúrgicamente en un centro de derivación de trauma laboral, por el mismo equipo quirúrgico y durante el período comprendido entre enero de 2013 y diciembre de 2019. Resultados: Se incluyeron 40 pacientes (39 hombres y una mujer). La tasa de complicaciones tempranas fue independiente del momento de la cirugía (antes o después de las 72h) (p=0,827). Se presentaron diferencias estadísticamente significativas entre ambos grupos en las variables edad, presión arterial sistólica, puntuación SOFA inicial y presencia de daño neurológico (p=0,014; p=0,029; p=0,032; p=0,012). La demora quirúrgica global se correlacionó con el puntuación SOFA al ingreso (p=0,007). Conclusión: La tasa de complicaciones en el postoperatorio temprano de fracturas toracolumbares no mostró diferencias significativas entre los grupos de cirugía temprana y tardía. Los pacientes operados antes de las 72h del trauma fueron más jóvenes, presentaron valores más elevados de presión arterial, menor daño fisiológico y asociaron síntomas neurológicos con mayor frecuencia. La demora quirúrgica se correlacionó positivamente con la puntuación SOFA al ingreso.(AU)

Resultados radiológicos y funcionales en fracturas de platillo tibial de alta energía / Radiological and functional results in high-energy tibial plate fractures

Resumen: Introducción: Las fracturas de platillo tibial por mecanismos de alta energía son lesiones graves que ocurren sobre una articulación de carga. Son difíciles de abordar, ya que además de afectar la estructura ósea de la pierna suelen tener lesiones de partes blandas asociadas. Objetivo: Evaluar los resultados radiológicos y funcionales de las fracturas de platillo tibial de alta energía con un mínimo seguimiento de un año. Material y métodos: Estudio retrospectivo, observacional y multicéntrico. Análisis de los resultados radiológicos y funcionales en el tratamiento de fracturas de platillo tibial de alta energía tratadas mediante reducción abierta y fijación interna (RAFI) entre 2014 y 2019. Resultados: 54 fracturas tratadas mediante RAFI. Seguimiento un año, 98.1% de consolidación en 13 semanas de promedio, 83.4% sin alteraciones del eje en plano coronal, 74% sin ensanchamiento articular postoperatorio. Escalas funcionales: Lysholm 82.1 puntos promedio y Oxford Knee Score (OKS) 39.5 puntos promedio. Conclusión: El rango de movilidad articular se redujo luego de una fractura de platillos tibiales de alta energía, pero con buenos resultados funcionales. Cuanto menor deseje y menor ensanchamiento radiográfico postoperatorio, se obtienen mejores resultados.

Sistema de doble movilidad. La solución francesa en pacientes añosos con fractura intracapsular de cadera y alto riesgo de luxación / Dual mobility system. The French solution in elderly patients with intracapsular hip fracture and high risk of dislocation

OBJETIVO: En la actualidad continúa la controversia respecto al tratamiento quirúrgico más adecuado de la fractura de cuello femoral desplazada en pacientes añosos o con alto riesgo de luxación. En nuestro estudio nos enfocamos en reportar resultados clínicos, funcionales y radiográficos de este tipo de pacientes tratados con artroplastia total de cadera usando el sistema de doble movilidad con un seguimiento mínimo de 2 años. MATERIALES Y MÉTODOS: En el periodo de enero de 2015 a enero de 2016 los pacientes con fractura del cuello femoral desplazada asistidos en las centrales de emergencia de los hospitales que participaron en el estudio fueron seleccionados. De 137 pacientes, 41 cumplían con uno o más de los criterios de inclusión y aceptaron la indicación terapéutica recomendada. Los pacientes fueron sometidos a artroplastia total de cadera utilizando prótesis con sistema de doble movilidad (cementada o no cementada). Todos los pacientes fueron evaluados con el Mini-Mental State Examination y la distancia de caminata en el preoperatorio, a las 3 y 6 semanas, a los 3 y 6 meses, al año y en años subsecuentes. Las evaluaciones radiográficas fueron programadas a tiempos similares. RESULTADOS: Se evaluaron 41 pacientes, con un seguimiento promedio de 2,4 años (rango 2 a 3,2 años). La media de edad fue de 85,2 (rango 80 a 96 años). Cuatro pacientes fallecieron en el periodo de seguimiento por causas no asociadas a la cirugía, con el implante funcionando. Hubo un solo caso de infección a los 8 meses de la cirugía, tratado con una revisión en un tiempo. No se reportaron casos de luxación en esta serie. CONCLUSIÓN: La utilización del sistema de doble movilidad para el tratamiento de fracturas del cuello femoral desplazadas en pacientes con alto riesgo de luxación y añosos ha demostrado buenos resultados clínicos y radiológicos, que fundamentan la indicación sistemática de uso en nuestros servicios

OBJECTIVE: Actually there is a controversy about the treatment of hip fractures on older patients with high risk of dislocation. Our study is focused on report clinico-functional and radiographic results in this population treated with total hip replacement using a dual mobility system after a minimum follow up of 2 years. MATERIALS AND METHODS: In the period from January 2015 to January 2016 patients assisted at the Emergency Unit at the participant hospital were recluted for participation. A total of 137 patients were assisted and 41 fulfilled the inclusion criteria and accepted to participate. All patients received a total hip replacement with a dual mobility system (cemented or uncemented). The patients were evaluated with the Mini-Mental State Examination, walking distance test, preop and postop at 3 and 6 weeks, 3 months, 6 months, one year and subsequent years. Radiographic evaluation was scheduled with clinico-functional review. RESULTS: Forty-one patients included, follow up average 2.4 years (range 2 to 3.2 years). Mean age 85.2 (range 80 to 96 years). Four patients died during follow up due to causes not related to the total hip replacement and the implant was functioning. One case have an infection and was revised in one stage procedure. One case have an infection at 8 months follow-up and was revised in one stage procedure. There were no dislocations. CONCLUSION: The use of dual mobility system in this high dislocation risk population has shown good clinical and functional results, and support the sistematic indication in our services

Estudio comparativo radiológico y funcional del abordaje anterior directo versus abordaje posterolateral de cadera / Comparative study of radiological and functional outcomes following a direct anterior approach versus to a posterolateral approach to the hip

Objetivo: Realizar una comparación funcional y radiográfica de los resultados iniciales obtenidos con la utilización de los abordajes anterior directo (AAD) y posterolateral (PL) en la artroplastia total de cadera (ATC). Material y método: Estudio longitudinal prospectivo multicéntrico en 80 pacientes (80ATC). Cuarenta pacientes fueron intervenidos mediante AAD y 40 pacientes mediante abordaje PL. Se recogieron los siguientes parámetros clínicos: anestesia, abordaje, longitud de la incisión cutánea, duración de la cirugía, discrepancia de longitud, dolor, complicaciones, tiempo de ingreso, escala funcional de Harris (HHS) y satisfacción de los pacientes. En cuanto a los parámetros radiográficos, se recogieron ángulo de inclinación acetabular, anteversión acetabular, integración del cotilo, integración y orientación del vástago y longitud del miembro inferior. Resultados: Dolor postoperatorio: AAD 4puntos; PL 4,3puntos. Tamaño incisión: AAD14cm; PL 15cm. Duración media del ingreso hospitalario: AAD 2,8días; PL 3,4días. HHS a las 3semanas: AAD 87,5puntos, PL 84puntos; a los 2meses: AAD 92puntos, PL 91puntos. Se detectó hundimiento del vástago femoral en 4 pacientes AAD y en un paciente PL, y mala alineación en 9 casos del grupo AAD. Conclusiones: Nuestros resultados muestran una leve mejoría inicial del AAD en la recuperación funcional y en el dolor de los pacientes, lo que permite una menor estancia hospitalaria. Esta diferencia se compensa aproximadamente a los 2meses del postoperatorio. Asimismo, se ha detectado un mayor índice de complicaciones en el AAD con el uso de vástagos no cementados estándar

Objective: To compare clinically and radiologically the results obtained using both a direct anterior approach (DAA) and posterolateral (PL) approach in total hip arthroplasty (THA). Material and methods: Multicentric longitudinal prospective study in 80 patients (80 THA). Forty patients underwent total hip arthroplasty through DAA and 40 through a PL approach. The following clinical parameters were collected: anaesthesia, length of surgical incision, duration of the procedure, lower limb discrepancy, pain, complications, hospitalization time, Harris Hip Score (HHS) and subjective patient satisfaction. Radiological measures collected were acetabular tilt angle, acetabular component version, osteointegration and lower limb length. Results: Postoperative pain: DAA 4points; PL 4.3points. Incision length: DAA 14cm, PL 15cm. Mean hospital stay: DAA 2.8days, PL 3.4days. HHS at 3weeks: DAA 87.5points and PL 84points; at 2months: DAA 92points and PL 91points. Femoral stem subsidence was noticed in 4 patients from DAA and 1 from PL. Malalignment was reported in 9 cases from the DAA group. Conclusions: Our results show an initial advantage of the DAA group regarding functional recovery and pain that enabled shorter hospitalization time. This difference equalled out over 2months following the procedure. Likewise, we detected a greater complication rate in the DAA group using standard cementless stems
