RESUMO

El objetivo de nuestro estudio es describir la distribución de la vascularización del músculo flexor digitorum superficialis para optimizar sus indicaciones en cirugía reconstructiva de miembro superior. MATERIAL Y MÉTODOS. Disecamos 15 antebrazos fijados según el método Thiel y coloreados mediante la inyección de latex en los vasos femorales. Centramos nuestro estudio en la disección del músculo flexor digitorum superficialis, seleccionando únicamente los pedículos vasculares que superan los 2 mm, valorando los resultados en función de sus relaciones anatómicas y longitud. RESULTADOS. El número total de arterias nutrientes del vientre muscular era de 219, localizándose en mayor porcentaje en el tercio medio del antebrazo. CONCLUSIÓN. De los resultados obtenidos de nuestro estudio podemos deducir que la arteria cubital y cubital recurrente aportan la vascularización dominante. Medialmente recibe ramas de la arteria cubital y cubital recurrente, en la parte profunda del vientre muscular. Lateral y proximalmente recibe ramas de la arteria mediana, mientras que lateral y distalmente recibe ramas de la arteria radial, que penetran en la superficie del músculo (AU)


We present an anatomical study that describes the distribution of the muscular perforators of the flexor digitorum superficialis muscle. MATERIAL AND METHODS. In this study we dissected 15 forearms fixed according to Thiel method and coloured latex injection in the femoral vessels. The study was centered on the flexor digitorum superficialis muscle. Only muscular perforator arteries with diameters over 2mm were selected. The vascular origin and length were also studied. In all cases, measurements were taken from the bicondyle line. RESULTS. The total number of arteries obtained from the muscle belly was 219, with the greatest percentage located in the half of the forearm. The principal vascular origin of the perforator arteries was the cubital artery. ONCLUSION. From the results obtained in our work, we can deduce that the ulnar and the ulnar recurrent arteries are the most dominant supply of the muscle. Medially , it receives many large branches from the ulnar recurrent and the ulnar artery. Laterally and proximally, it receives small branches from the median artery, and distally, it receives several small branches from the radial artery that enter the superficial surface of the muscle (AU)

RESUMO

El uso de células madre mesenquimales obtenidas de grasa (CMM) puede aumentar las posibilidades de éxito de la sutura meniscal. Se colocaron 105 CMM en una lesión longitudinal de 5mm en la zona avascular del menisco interno de 12 conejos y se suturó con un punto simple. Se usaron las rodillas contralaterales sin CMM como controles.Lo animales se sacrificaron a las 12 semanas y se examinaron los meniscos. En los 12 meniscos con CMM aparecieron cicatrizaciones parciales en tres y completas en tres. En los 12 controles hubo cicatrización parcial en uno y ninguna completa. El análisis microscópico identificó fibrocartílago meniscal en buen estado en las zonas cicatriciales (AU)


The use of mesenchimal stem cells derived form fat (MSC) can increase the success rate of meniscal suture. 105 MSC were placed in a longitudinal lesion at the avascular zone of the medial menisci of 12 rabbits that was sutured with a single stitch. The contralateral knee was used as control without MSC. The animals were sacrificed after 12 weeks and the menisci were examined. In the 12 menisci treated with MSC, partial healing was observed in three and complete healing in another three. In the 12 controls there was partial healing in one and no complete healings. Microscopical analysis identified well formed meniscal fibrocartilage in the healed zones (AU)
