Xiphoid Cartilage

Cartilago xiphoidea

Overview

The xiphoid process is the caudal cartilaginous extension of the sternum. It is broad and flat in the horse, with the xiphoid cartilage extending caudally. It provides attachment for the diaphragm, linea alba, and rectus abdominis muscle. The xiphoid cartilage is the cartilaginous plate extending caudally from the xiphoid process. It provides the caudal-most attachment of the ventral body wall and diaphragm. The xiphoid cartilage may partially ossify in older horses.

Quick Answer: The caudal extension of the sternum. The xiphoid process is the bony portion; the xiphoid cartilage is the cartilaginous plate that extends caudally and provides attachment for the diaphragm and linea alba. It may partially ossify in older horses.

Clinical Significance

Isolated clinical problems are uncommon. Relevant mainly as an anatomical landmark for abdominal surgery and imaging. Partial ossification is a normal age-related change.

Common Conditions & Injuries

Xiphoid fracture or displacement

## Overview Fracture or displacement of the xiphoid process (the caudal tip of the sternum) results from trauma to the ventral chest or abdomen. It causes ventral abdominal pain, pain on palpation of

Xiphoid trauma

## Overview Xiphoid trauma is direct impact to the caudal sternum, causing pain, reluctance to flex the trunk, and ventral swelling. It may accompany fracture or soft-tissue bruising. Most cases are

Ventral hernia

## Overview A ventral hernia is a disruption of the abdominal wall, often near the xiphoid, from trauma. It appears as a soft, reducible swelling on the ventral midline that may enlarge with strainin

Frequently Asked Questions

What is Xiphoid fracture or displacement in horses?

## Overview Fracture or displacement of the xiphoid process (the caudal tip of the sternum) results from trauma to the ventral chest or abdomen. It causes ventral abdominal pain, pain on palpation of the caudal sternum, and reluctance to round the back. ## Causes Direct trauma. ## Diagnosis Palpation and radiographs or ultrasound. ## Treatment Rest and pain management. Most heal without surgery. ## Recovery and Prognosis Good. ## Prevention Trauma avoidance. Signs include: ventral abdominal pain; pain on palpation of the caudal sternum; reluctance to round the back

What is Xiphoid trauma in horses?

## Overview Xiphoid trauma is direct impact to the caudal sternum, causing pain, reluctance to flex the trunk, and ventral swelling. It may accompany fracture or soft-tissue bruising. Most cases are managed with rest. ## Causes Blunt trauma to the ventral abdomen or chest. ## Diagnosis Palpation and imaging if fracture is suspected. ## Treatment Rest and anti-inflammatories. ## Recovery and Prognosis Good. ## Prevention Safe environments. Signs include: pain at the caudal sternum; reluctance to flex the trunk; ventral swelling

What is Ventral hernia in horses?

## Overview A ventral hernia is a disruption of the abdominal wall, often near the xiphoid, from trauma. It appears as a soft, reducible swelling on the ventral midline that may enlarge with straining. Most are managed conservatively if the contents reduce easily and there is no bowel compromise. ## Causes Trauma. ## Diagnosis Palpation and ultrasound. ## Treatment Supportive bandaging and rest for small hernias. Surgical repair for large or non-reducible ones. ## Recovery and Prognosis Good for uncomplicated hernias. ## Prevention Trauma avoidance. Signs include: soft reducible swelling on the ventral midline; may enlarge with straining
