Abstract
EL AREA DISTAL DEL VASTAGO (1) TIENE SECCION TRANSVERSAL CUADRADA Y TIENE DIENTES (13) EN LAS ARISTAS (12) DEL CUADRADO QUE SIRVEN DE APOYO SOBRE EL HUESO (11). FRENTE A LOS VASTAGOS DE SECCION TRANSVERSAL RECTANGULAR, EN ESTOS SE NIVELAN LAS TENSIONES ANULARES EN LA DIRECCION PERIFERICA QUE ORIGINA LA INSERCION DEL VASTAGO (1) EN EL HUESO (11), SIN QUE SE PIERDE LA VENTAJA QUE SE OBTIENE AL INSERTAR VASTAGOS ANGULOSOS EN HUECOS REDONDOS, ES DECIR LA EXISTENCIA DE HOLGURAS (9), ENTRE HUESO Y VASTAGO, FAVORABLES AL CRECIMIENTO Y REVASCULARIZACION DEL HUESO.
