Costoxiphoid ligaments

Costoxiphoid ligaments

The Costoxiphoid ligaments are a group of ligaments that connect the costal cartilages of the lower ribs to the xiphoid process of the sternum. These ligaments play an important role in stabilizing the rib cage and maintaining its structural integrity.

Anatomy

The costoxiphoid ligaments consist of several bands of fibrous tissue that extend from the inferior aspect of the costal cartilages to the superior aspect of the xiphoid process. They are located in the lower part of the rib cage, specifically between the seventh, eighth, and ninth ribs and the xiphoid process.

Function

The primary function of the costoxiphoid ligaments is to provide stability to the rib cage. They help to maintain the alignment of the ribs and prevent excessive movement or displacement. Additionally, these ligaments contribute to the overall flexibility of the rib cage, allowing for expansion and contraction during respiration.

Clinical Significance

Injuries to the costoxiphoid ligaments are relatively rare but can occur as a result of trauma or repetitive strain. Common symptoms of costoxiphoid ligament injuries include localized pain, tenderness, and difficulty breathing deeply. Treatment typically involves rest, pain management, and physical therapy to promote healing and restore function.
