ABSTRACT
The aim of our study was to verify the prevalence of the sternal foramen in adult cadavers and dry bones, as well as to determine its exact localization and relation to acupuncture points. One hundred eighty sternums fixed and contained in 10 percent formaldehyde solution were examined, of which 100 were dry bones and 80 belonged to adult cadavers. The morphometric measures were expressed in millimeters when measuring the length 1) from jugular incision to the foramen (JI-F); 2) from sternal angle to the foramen (EA-F); 3) from xiphoid process to the foramen (XP-F). Statistical analysis was performed to compare expected vs obtained foramina frequency, using Fisher's test (p0.05 was considered significant). The results showed 16.6 percent sternal foramina, significant higher than expected (p0.0248). Of the 30 foramina, 53.3 percent were found in cadavers, of which one was a woman, and 46.7 percent sternums were found in dry bones. Of the cadavers with sternal foramen, 10 foramina were at the 5th sternochondral articulation level and 6 foramina at the 4th sternochondral level. Of the 14 analyzed dry bones, 9 foramina were at the space between the 4th and the 5th costal pit level and 5 foramina were at the 5th costal pit level. The mean±SD (mm) total length of the sternums was 151.8+/-34 and the measures JI-F, EA-F, and XP-F were, respectively, 103.8+/-22.1mm, 65.6+/-15mm and 46.9 +/-15mm. Knowledge of this occurrence is important to avoid serious heart injury by needle insertion, especially as this area holds a commonly used acupuncture point and sternal puncture...
RESUMEN
El objetivo del estudio fue verificar la prevalencia del foramen esternal en cadáveres adultos y huesos secos, así como, determinar su localización y su relación con los puntos de acupuntura. Fueron examinados 180 esternones fijados en solución de formol al 10 por ciento, 100 eran huesos secos y 80 pertenecían a cadáveres de individuos adultos. Las medidas morfométricas se expresaron en milímetros, efectuándose las siguientes mediciones 1) desde la incisura yugular al foramen; 2) desde el ángulo esternal al foramen y 3) desde el proceso xifoides hasta al foramen. El análisis estadístico permitió comparar la frecuencia de los forámenes, usando el test de Fisher (p 0,05 ). Los resultados mostraron la presencia del foramen esternal en 16,6 por ciento de los casos, siendo significativamente mayor a lo esperado (p 0,0248). De los 30 forámenes, el 53,3 por ciento se encontró en cadáveres y en el 46,7 por ciento en los huesos secos. De los cadáveres con foramen esternal, 10 forámenes se encontraban a nivel de la 5 articulación esternocondral y 6 a nivel de la 4 articulación esternocondral. De los 14 forámenes de los huesos secos, 9 forámenes se encontraban entre entre el 4 y el 5 espacio intercostal y 5 se localizaban a nivel del 5 articulación. La longitud total del esternón fue 151,8 mm +/- 34 y las medidas desde la incisura yugular al foramen, desde el ángulo esternal al foramen y desde el proceso xifoides hasta al foramen fueron, 103,8 +/- 22,1 mm, 65,6 +/- 15 mm y 46,9 +/- 15 mm, respectivamente. El conocimiento de este hecho es importante para evitar la lesión cardiaca grave por la inserción de agujas, ya que esta zona tiene un punto de acupuntura de uso común en la punción esternal...
