The investigation has been carried out in 95 preparations of the anterior chest wall of corpses of humans of either sex aged from newborns to 90. It has been established that the blood supply of all the layers of sternum is brought about by the anterior and medial branches of the internal sternum artery forming subperiosteal plexuses on its anterior and posterior surfaces. The posterior plexus is better developed. Its loops are of less size and denser per a square surface unit. Three types of blood supply of the manubrium sterni posterior surface have been distinguished (right-side, balanced and left-side types) as well as two variations of blood supply of the sternum body (in the first variant two sternal branches approach the sternum at the level of every intercostal space, in the second variant--only one does). The outflow of the venous blood from the sternum is brought about into the anterior and posterior venous subperiosteal plexuses and then via one of the three anatomical variations into the internal thoracic veins. The subperiosteal network of the sternum in newborns and infants is of segmentary character and is formed in relation with developing ossification nuclei. With age, in the process of fusion of the ossification nuclei the subperiosteal network looses its segmentary character and acquires a common total character.
该研究在95具年龄从新生儿到90岁的男女尸体的前胸壁标本上进行。已确定胸骨各层的血液供应由胸骨内动脉的前支和内侧支提供，这些分支在胸骨的前、后表面形成骨膜下丛。后丛发育较好。其袢较小，每单位面积更密集。已区分出胸骨柄后表面的三种血液供应类型（右侧型、平衡型和左侧型）以及胸骨体血液供应的两种变异（第一种变异中，每一个肋间隙水平有两个胸骨支靠近胸骨，第二种变异中只有一个）。胸骨的静脉血经骨膜下前、后静脉丛流出，然后通过三种解剖变异之一进入胸廓内静脉。新生儿和婴儿胸骨的骨膜下网络具有节段性特征，与发育中的骨化核有关。随着年龄增长，在骨化核融合过程中，骨膜下网络失去其节段性特征，获得共同的整体特征。
