Meridianos tendinomusculares (Jīng Jīn) y tejido fascial, comparativa anatómica y funcional

2016

The description of the pathways of the Jīng Jīn meridians is based on empirical observations carried out more than 2000 years ago, and though historical records have shown their possible anatomical basis, nowadays these energetic pathways lack a solid scientific base from the biomedical standpoint. Nonetheless, the comparison between the pathways and function of the Jīng Jīn with the new insights regarding contributions to anatomy and physiology of the fascial system brought from western medicine allows for meeting points and closer relations between the two areas of knowledge. Physiologically, both the Jīng Jīn and the fascial system participate in common structural, biomechanical, integra…

Serratus anterior contraction during resisted arm extension (GravityFit) assessed by MRI

2019

Background: Scapular stabilization is a common focus of shoulder rehabilitation. Objective: Examine contraction of serratus anterior during a bilateral arm extension exercise with axial compression using an exercise device (GravityFit) by magnetic resonance imaging (MRI). Methods: MRI was performed under two conditions: rest and static arm extension with axial compression. Load was set at 20% of age, sex and weight estimated bench press one-repetition maximum. A T2-weighted sequence was used to collect 14 axial images of the upper thoracic spine and shoulder bilaterally. Mean muscle length and thickness were calculated for the whole muscle and in equidistant subregions of the muscle in its …

Low-energy extracorporeal shockwave therapy (ESWT) improves metaphyseal fracture healing in an osteoporotic rat model.

2017

Purpose As result of the current demographic changes, osteoporosis and osteoporotic fractures are becoming an increasing social and economic burden. In this experimental study, extracorporeal shock wave therapy (ESWT), was evaluated as a treatment option for the improvement of osteoporotic fracture healing. Methods A well-established fracture model in the metaphyseal tibia in the osteoporotic rat was used. 132 animals were divided into 11 groups, with 12 animals each, consisting of one sham-operated group and 10 ovariectomized (osteoporotic) groups, of which 9 received ESWT treatment. Different energy flux intensities (0.15 mJ/mm2, 0.35 mJ/mm2, or 0.55 mJ/mm2) as well as different numbers o…

Update on the role of molecular factors and fibroblasts in the pathogenesis of Dupuytren’s disease

2016

The mechanism by which the fibroblast is able to trigger palmar fibromatosis is still not yet fully understood. It would appear certain that the “abnormal” fibroblasts continuously synthesise profibrotic cytokines which are able to determine the activation to myofibroblasts, to stimulate them to the further proliferation and synthesis of other cytokines, to modify the cells’ differentiation and ultrastructural characteristics, as well as the production of matrix and other proteins. Several fibroblast growth factors have been suggested to be responsible of an abnormal cell activation with an aberrantly elevated collagen synthesis and extracellular deposition in Dupuytren’s disease, as TGF-Be…

Cirugía de la mano reumática: nuevas expectativas para una vieja conocida

2017

ResumenEs importante que todos los especialistas que tratan a pacientes afectados de artritis reumatoide (AR), conozcan las distintas opciones terapéuticas disponibles, tanto médicas como quirúrgicas, y su manejo en las distintas fases del tratamiento. Nuestro objetivo es actualizar lo que como cirujanos debemos saber sobre el tratamiento médico de la enfermedad, cómo manejar los fármacos durante la programación de la cirugía y cuál es la evidencia sobre las distintas opciones quirúrgicas que podemos barajar ante diversas situaciones originadas por un aparente mismo patrón: la sinovitis.

L’échographie en réhabilitation, une émergence anglo-saxonne

2017

Resume L’echographie est un outil qui a vu le jour dans les annees 1950 en medecine, et depuis s’est considerablement developpe pour de nombreuses professions de sante dont les kinesitherapeutes. Son accessibilite, son absence d’effet secondaire et son faible cout en font un moyen d’evaluation indispensable pour les kinesitherapeutes explorant les alterations du mouvement et cherchant a ameliorer la pertinence du plan de traitement propose aux patients. De nombreux pays ont deja œuvre dans le sens de l’amelioration de la formation et de la pratique en echographie pour les kinesitherapeutes. L’integration du developpement de cet outil en France doit necessairement passer par des collaboratio…

Las coaliciones tarsianas como causa de dolor en el pie infantil: opciones terapéuticas

2022

Resumen Antecedentes y objetivo La coalicion tarsiana puede ser causa de dolor de medio-retropie en ninos mayores. El objetivo es analizar los tipos de coalicion tratados en nuestro centro hospitalario de 2010 a 2019 asi como el tratamiento realizado. Material y metodo Estudio observacional, descriptivo y retrospectivo de 18 pacientes con coalicion tarsiana, 8 mujeres y 10 hombres, de 11,9 ± 2,6 anos de edad. Se recogieron datos epidemiologicos, hallazgos clinicos y de pruebas de imagen y tratamiento realizado. Resultados Se revisaron 25 pies (38,8% bilaterales). El principal sintoma fue el dolor. Un 64% se asociaba a pie plano-valgo. El 52% se localizaba en la articulacion calcaneo-escafoi…

Hyaluronic-based antibacterial hydrogel coating for implantable biomaterials in orthopedics and trauma. From basic research to clinical applications.

2018

Bacterial colonization of implanted biomaterials remains one of the most challenging complications in orthopedics and trauma surgery, with extremely high social and economic costs. Antibacterial coating of implants has been advocated by many experts as a possible solution to reduce the burden of implant-related infection and several different solutions have been proposed in the last decades. However, while most of the investigated technologies have shown their efficacy in vitro and/or in vivo, only few were able to reach the market, due to clinical, industrial, economic and regulatory issues. Hyaluronic acid composites have been previously shown to possess antifouling capabilities and have …

Utilización del ácido tranexámico tópico en la artroplastia total primaria de cadera. Eficacia y seguridad. Nuestra experiencia

2020

Resumen Antecedentes y objetivo El acido tranexamico por via intravenosa ha demostrado que disminuye el sangrado y la necesidad de transfusiones en la artroplastia total de cadera, aunque tiene un riesgo teorico de producir fenomenos tromboembolicos. Recientemente, se han publicado algunos trabajos con la aplicacion del acido tranexamico topico, sin haberse definido todavia cual es el protocolo de administracion ideal. El objetivo de este trabajo fue demostrar que nuestro protocolo de administracion topica de acido tranexamico es eficaz y seguro. Materiales y metodos Recogida de datos de una serie prospectiva de 80 artroplastias primarias de cadera, en las que se utilizo un protocolo de aci…
