The lateral borders are each marked above by a depression for the first costal cartilage, and below by a small facet, which, with a similar facet on the upper angle of the body, forms a notch for the reception of the costal cartilage of the second rib. If there is an infection, the wires may need to be pulled out, and a plastic surgery consult generally must be made so that the sternum can be closed with a muscle flap. It is located in the anterior median part of the chest wall.button#button{background:url(https://www.earthslab.com/wp-content/uploads/2018/09/thorax-bones.jpg) no-repeat scroll 0 0 transparent;color:#000;cursor:pointer;font-weight:700;height:800px;padding-bottom:2px;width:100%;border-color:#e4e4e4;border-width:1px;border-style:solid;border-radius:10px;background-position:center;margin-top:20px} function changeImage() { You can say thank you by SUBCRIBING to my Channel and sharing this video. - Production, Structure & Benefits, Arrow Pushing Mechanism in Organic Chemistry, Working Scholars Bringing Tuition-Free College to the Community. In children, strong sutures can be used toput the sternum back together, but in all individuals above the age of 2, stainless steel wires are required to realign and close the sternum. The inferior angle has a small facet, which, with a corresponding one on the xiphoid process, forms a notch for the cartilage of the seventh rib. sternal angle is the location of the attachment of the costal cartilage of the 2nd rib to the sternum; an imaginary horizontal plane through the sternal angle passes through the T4/T5 intervertebral disc and marks the inferior boundary of the superior mediastinum . Muscles Connected on the Posterior and Anterior surfaces of Sternum are summarized below: Upper part, the manubrium sterni/episternum, Lower part, the xiphoid process/metasternum, On every side, it gives connection to 2 muscles: Sternohyoid at the level of clavicular notch, andSternothyroid at the level of facet for 1st costal cartilage, Lower half is associated with arch of aorta and Upper half is associated with three branches of the arch of aorta, viz. The manubrium and proximal sternum are routinely opened upduring open-heart surgery.

Assessment of the heart involves inspection, palpation, and auscultation. The optimal location for auscultation of the aortic valve is generally the right second intercostal space, whereas the optimal location for auscultation of the pulmonic valve is generally the left second intercostal space.
