Xiphoid Process Of The Sternum, Lateral View

Description

Xiphoid process anatomy is centered in this lateral image of the distal sternum, where the thin xiphoid projects inferiorly from the sternal body at the xiphisternal junction. From this side perspective, the anterior surface of the sternum sits superficial to the mediastinum, while the posterior cortex and the inferior tip of the xiphoid are readable as a narrow, blade-like extension. Superior to the xiphoid, the distal sternal body provides the broader bony plate; inferiorly, the xiphoid aligns with the upper abdominal wall and the central tendon region of the diaphragm by proximity and attachment footprint. A small structure. Big consequences. Clinically, the xiphoid is the landmark everyone thinks they can find, yet its size and angulation vary widely and that variability matters when teaching external chest compressions or placing retractors at the inferior end of a median sternotomy. Excessively caudal hand placement during CPR can fracture the xiphoid and transmit force to the left lobe of the liver or anterior diaphragm, so a strict read on the xiphisternal junction helps trainees understand why compressions target the lower half of the sternal body, not the xiphoid itself. The lateral viewpoint also supports procedural anatomy discussions around subxiphoid access corridors, where the relationship of the distal sternum to the upper abdomen is more intuitive than in an anterior view. Use this illustration in thoracic wall and mediastinum teaching sessions, anatomy lab manuals, emergency medicine training decks (CPR landmarks and complications), and surgical education materials that reference the inferior limit of sternotomy and the xiphoid as a surface landmark. It also fits well in radiology and ultrasound primers that correlate surface anatomy to the xiphisternal region on lateral chest imaging and subcostal windows.
