Efectos sobre el codo de la resección de la cabeza radial por fractura aislada de la cabeza del radio en pacientes jóvenes / Effects on the elbow of radial head resection following isolated radial head fracture in young patients

Fundamento: La resección de la cabeza radial ha sido un tratamiento muy utilizado en casos de fractura no reconstruible de la cabeza del radio; algunos autores impulsan el uso de prótesis de cabeza radial. El propósito de este trabajo fue evaluar el resultado a largo plazo de la exéresis de la cabeza del radio por fractura aislada y su repercusión radiológica y funcional a nivel del codo. Pacientes y método. Se han revisado de forma retrospectiva cuarenta y cuatro historias clínicas de pacientes con resección de la cabeza del radio por fractura aislada, sin lesiones asociadas, en pacientes menores de cuarenta años y con un seguimiento mínimo de quince años. Se ha valorado la presencia de dolor, movilidad, fuerza y estabilidad del codo y se ha comparado con el lado contralateral sano. El estudio radiológico recoge la presencia de artrosis, calcificaciones, acortamiento del muñón proximal y medición del ángulo de carga. Se ha utilizado el cuestionario Dishabilities of the Arm, Shoulder and Hand (DASH) para valorar el grado de discapacidad percibido por el paciente. Resultados: El grupo de estudio se compone de diez mujeres y treinta y cuatro varones, con una edad media en el momento de la fractura de 28,6 años (rango 15-40) y un tiempo de evolución o seguimiento medio de 28,5 años (rango 16-38). La afectación en el lado dominante fue en treinta casos (23 diestros y 7 zurdos). Treinta y nueve pacientes (88,6%) no tenían dolor a nivel del codo y en el resto era leve o moderado. La pérdida de movilidad y fuerza respecto al lado contralateral fue de 1,5% para flexo-extensión, 3,5% para prono-supinación, 7,9% de fuerza de flexión y 3,5% de fuerza de extensión del codo. Se encontraron cuatro casos de inestabilidad en valgo y dos posterolateral rotatoria. La mediana del cuestionario DASH fue de 2,5 puntos (rango 0-30,8). Grados variables de artrosis están presentes en 93,3% de los codos y 54,4% de calcificaciones. El aumento medio del ángulo de carga fue de 7,7º respecto al lado sano (rango de 0,9 a 15,8º). Conclusiones: La resección de la cabeza radial por fractura aislada en pacientes jóvenes presenta unos resultados satisfactorios, con pérdidas muy bajas de movilidad y fuerza a nivel del codo. A pesar de la presencia alta de cambios artrósicos y menor de signos clínicos de inestabilidad, el dolor y discapacidad en el codo son muy bajos. En base a estos resultados, la resección de la cabeza radial es una técnica válida para fracturas aisladas incluso en pacientes jóvenes (AU)

Background: Radial head resection has been a widely used procedure in cases of non-reconstructable radial head fracture. Some authors propose the use of radial head arthroplasty. The purpose of this study was to evaluate the long-term outcome of radial head resection for isolated fracture, without instability at the time of the fracture, and its radiological and functional repercussions at the elbow level. Methods: We reviewed 44 clinical records with acute resection of the radial head following isolated radial head fracture, with absence of associated injuries, younger than forty, with a minimum follow-up of 15 years. Information was collected on elbow pain, biomechanical function, flexion and extension elbow strength and elbow instability compared with the non-affected side. A radiological study was conducted on all patients to determine the presence of degenerative changes, calcifications and measurement of the carrying angle. Outcomes were evaluated with Disabilities of the Arm, Shoulder and Hand score as an instrument to measure the patient’s perceived disability. Results: The group under study is made up of ten women and thirty-four men, with an average age at the time of fracture of 28.6 years (ranging from 15-40) and an average time since the fracture or follow-up time of 28.5 years (ranging from 16-38). The affectation was on the dominant side in thirty cases (23 right-handed and 7 left-handed). Thirty-nine patients (88.6%) had no elbow pain, and in all other cases was mild or moderate. Loss of mobility and strength was 1.5% for flexo-extension, 3.5% for prono-supination, 7.9% for flexion strength and 3.5% for extension strength. We appreciated four cases of valgus instability and two of postero-lateral instability. The average DASH score was 6.9 points. Radiographic changes of arthritis were present in 93.3% and 54.4% f calcifications. The mean increase of carrying angle was 7.7º compared with non-affected gide (ranking from 0.9-15.8º). Conclusion: Radial head resection for isolated fracture in young patients presents satisfactory results, with very low losses of elbow mobility and strength. Despite the high presence of osteoarthritic changes or lower clinical signs of instability, elbow pain and disability are very low. Our conclusion, based in these results, is that radial head resection is still a useful surgical procedure for isolated fractures even in young patients (AU)

Cross-cultural adaptation of the Zurich Claudication Questionnaire.Validation study of the Spanish version.

BACKGROUND: In the last few years, instruments that measure outcomes and quality of life as perceived by the patient have become tools of great clinical value. The Zurich Claudication Questionnaire is one of the main instruments for the assessment of patients suffering from lumbar spinal stenosis. Nonetheless, no valid version has been published for use in the Spanish population. METHODS: The Zurich Claudication Questionnaire was translated and cross-culturally adapted to Spanish and the psychometric characteristics of the new version were then studied. Seventy-six patients were selected who were to undergo epidural steroid injection or were seen in the Hospital Complex of Navarre Spinal Unit. RESULTS: The Spanish version of the Zurich Claudication Questionnaire shows high Cronbach alpha internal consistency values, high reproducibility, a good correlation with the most important low back condition questionnaires used worldwide and good sensitivity for detecting clinical change in patients who undergo epidural steroid injection. CONCLUSION: This study resulted in a version of the Zurich Claudication Questionnaire or Swiss Spinal Stenosis Questionnaire translated and cross-culturally adapted to Spanish, with highly reliable, valid and sensitive psychometric characteristics. These proven properties make the Zurich Claudication Questionnaire available for the Spanish population, to evaluate outcomes and health status as perceived by patients with spinal stenosis and claudication syndrome.

Introducción: En los últimos años, los instrumentos de medida de resultados y calidad de vida percibida por el paciente, se han convertido en herramientas de gran utilidad clínica. El Cuestionario de Claudicación de Zurich es uno de los principales instrumentos para el estudio de los pacientes afectos de estenosis del canal lumbar. Actualmente, no se ha publicado una versión validada para su uso en la población española. Métodos: El Cuestionario de Claudicación de Zurich ha sido traducido y adaptado transculturalmente al español, y se han estudiado las características psicométricas de la nueva versión. Se seleccionaron 76 pacientes a los que se les iba a realizar una infiltración epidural de esteroides o que eran vistos en consultas de la Unidad de Raquis Quirúrgico del Complejo Hospitalario de Navarra. Resultados: La versión española del Cuestionario de Claudicación de Zurich muestra altos valores de consistencia interna alfa de Cronbach, alta reproducibilidad, una buena correlación con los cuestionarios de patología lumbar más importantes a nivel mundial, y una buena sensibilidad para detectar cambios clínicos en pacientes a los que se les realiza una infiltración epidural de corticoides. Conclusión: Se ha obtenido una versión del Cuestionario de Claudicación de Zurich traducida y adaptada transculturalmente al español, con altos valores en las características psicométricas de fiabilidad, validez y sensibilidad. Esto permite, en la población española, evaluar los resultados y el estado de salud percibido por los pacientes con estenosis de canal y síndrome de claudicación (AU)
