Utilización de los tornillos canulados sin cabeza intramedulares en el tratamiento de las fracturas de la mano -estudio anatomico en los dedos largos AbstractObjective To quantify the cartilaginous and tendinous lesions produced upon percutaneous introduction of intramedullary cannulated screws as osteosynthesis material in metacarpal and phalangeal fractures. Materials and Methods Seven anatomical models and one non-replanted hand were used. The measurements of 30 metacarpals and proximal and middle phalanges were taken. Cannulated screws with complete and partial threads were placed percutaneously through the metacarpal head and the proximal and middle phalanges, reproducing the actions performed in the clinic. The following measurements were performed: A) Percentage of the damaged cartilaginous area and its location. B) Damage to the extensor apparatus and its distance to the bone insertion point. C) Bone marrow size. Results (A) The percentages of the damaged areas in the metacarpals, proximal and middle phalanges were 5.7%, 13.35% and 9.62%, respectively. (B) The damage to the extensor apparatus was less than 3 mm with a 4-mm distance to the bone insertion point and (C) We have obtained the measurements of the intramedullary bone and from them, we calculated the width of the most appropriate screw. Conclusion In conclusion, the use of retrograde and percutaneous cannulated screws is a reliable technique with regard to the associated morbidity, and we present an approximation regarding the most appropriate screw for each location. ResumenObjetivo El objetivo de este estudio es cuantificar las lesiones cartilaginosas y tendinosas que se producen al introducir tornillos canulados intramedulares percutá-neos como material de osteosíntesis en fracturas de metacarpianos y falanges.
Introducción El uso de tornillos intramedulares de compresión en la fijación de las fracturas extraarticulares de metacarpianos y falanges, es un método de osteosíntesis en auge para el tratamiento de fracturas inestables transversas u oblicuas cortas. Pero hasta el momento, los criterios para la determinación del tornillo adecuado no han sido tratados en la literatura. Sin embargo, una incorrecta selección puede causar graves complicaciones. El objetivo del estudio es seleccionar el tornillo canulado de compresión correcto para cada paciente a partir de medidas obtenidas en radiografías simples en proyecciones convencionales. Material y Métodos Se estudiaron las radiografías de mano de 100 pacientes, en proyección anteroposterior y oblicua, midiendo los dedos largos. Se buscó la medida limitante, que se define como la menor dimensión de la medular en un corte transversal del hueso, tanto para los metatacarpianos, como para las falanges proximales y medias. Resultados La medida limitante de los metacarpianos se valora en las radiografías PA y en las falanges proximales y medias en las oblicuas. Se observó una gran variabilidad en la medida limitante, que se mantiene cuando estudiamos por género. Además de una regresión lineal inversa entre el tamaño de la medular y el tamaño de las corticales. Conclusiones El objetivo de este estudio fue determinar mediante radiología convencional los diámetros de las cavidades medulares de metacarpianos y falanges, y usar esos como guía en la selección del diámetro del tornillo canulado, y de ese modo, tratar de hacer más predecible la obtención de resultados óptimos evitando la aparición de complicaciones potencialmente graves.
The nails are important elements of the finger, not only aesthetically, but also for its functionality. Not only to protecting the tip of the finger helps us but also to perform meticulously fine dexterity activities. Due to the high incidence of nail injuries seen in a trauma emergency service, it is essential to know, at least, basic aspects of the anatomy and physiology of the nail and what should be the appropriate treatment based on the injury presented by the patient. Injuries such as subungual hematomas are resolved in short time, however, more complex lesions require minor surgical intervention to obtain good results. In this chapter, additionally to reviewing the anatomy-physiological aspects of the nail, the principles of treatment of nail traumas are detailed.
