胸骨的厚度及其临床意义

Anatomical observation of The Sternum Its Clinical Stgnificance

用成人干燥胸骨30例,测量胸骨前、后皮质厚度,胸骨厚度并计算出骨髓腔厚度.胸骨柄前皮质厚为1.26±0.18mm(0.5～4.0),后皮质厚为0.99±0.06mm(0.4～2.5),骨髓腔厚9.07±1.75mm(4.6～15.2),胸骨角前皮质厚为1.75±0.25mm(0.6～6.2),后皮质厚为1.53±0.21mm(0.4～4.2),骨髓腔厚为8.08±0.40mm(3.0～13.0),胸骨体前皮质厚为1.13±0.09mm(0.5～3.1),后皮质厚为1.05±0.09mm(0.4～3.0),骨髓腔厚为6.39±1.37mm(2.6～13.0).除胸骨角前皮质太厚外,胸骨体、胸骨柄各部均可用头皮静脉针行胸骨骨髓穿刺但以胸骨体为最佳穿刺部位.胸骨休、胸骨角及胸骨柄的前皮质较其后皮质均厚.

The thickness of sternum and compact substance of sternum were meas-ured in 30 sterna and anteropoterior diameter of medullary cavity of diff-erent part of sterna were computed. The data obtained in this paper provi-ded anatomical basis for clinical selecting puncture point of sternum.
