During chest compressions in cardiopulmonary resuscitation (CPR), it is possible to fracture or dislodge the xiphoid process, potentially leading to punctures or lacerations of the diaphragm. Furthermore, inadvertent liver puncture resulting in life-threatening internal bleeding can occur.
Some parents report that their child's pectus carinatum seemingly popped up overnight. Second most common is the presence of pectus carinatum at or shortly after birth. The condition may be evident in newborns as a rounded anterior chest wall. As the child reaches age 2 or 3 years of age, the outward sternal protrusion becomes more pronounced.
The sternum (pl.: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage , thus helping to protect the heart , lungs , and major blood vessels from injury.
The sternum is a long, flat bone that forms the front of the rib cage. The cartilages of the top seven ribs (the true ribs) join with the sternum at the sternocostal joints. The costal cartilage of the second rib articulates with the sternum at the sternal angle making it easy to locate. [9] The manubrium is the wider, superior portion of the ...
The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the body and xiphoid process of the sternum. [2] The thoracic diaphragm attaches to the costal margin. [3] The costal angle is the angle between the left and right costal margins where they join the sternum. [2]
The first seven pairs are connected with the sternum; the next three are each articulated with the lower border of the cartilage of the preceding rib; the last two have pointed extremities, which end in the wall of the abdomen. [2] Like the ribs, the costal cartilages vary in their length, breadth, and direction. They increase in length from ...
The term “flat bone” is something of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.
The sternal angle is a palpable and visible landmark in surface anatomy, presenting as either a slight body ridge or depression upon the upper chest wall which corresponds to the underlying manubriosternal joint. [4] The sternal angle is palpable and often visible in young people. [2]: 319
