Interfoveolar ligament cysts are a relatively uncommon condition that affects the ligament within the hip joint. Often associated with the ligament that helps stabilize the head of the femur (commonly known as the ligamentum teres), these cysts can cause pain and discomfort in the hip area. In this guide, you will find clear explanations about the anatomy and function of this ligament, what can lead to cyst formation, how to recognize and diagnose the condition, treatment options, and ways to prevent complications.

Interfoveolar ligament cysts are fluid-filled sacs that develop within or near the interfoveolar ligament, a small but important band of tissue in the hip joint. They may vary in size and can sometimes cause pain, restrict movement, or lead to joint instability if they grow or press against surrounding tissues.

Understanding the condition helps in early diagnosis and treatment, potentially preventing further joint damage. With the right care, many people with these cysts can manage symptoms and maintain a good quality of life.

Anatomy and Pathophysiology

The Interfoveolar Ligament

Structure:

• The interfoveolar ligament is a fibrous band found in the hip joint.
• It connects the femoral head (the top part of your thigh bone) to other structures within the joint, contributing to joint stability.

Blood Supply:

• Like many ligaments, it has a small network of blood vessels.
• The limited blood supply means that injuries or inflammation may heal slowly.

Nerve Supply:

• Nerve endings in the ligament transmit pain signals when irritated.
• This is why damage or inflammation in the ligament can be particularly painful.

Functions:

• Helps stabilize the hip joint by keeping the femoral head in place.
• Contributes to the overall balance and movement of the hip.

Pathophysiology: How Do Cysts Develop?

• Formation: Cysts form when fluid accumulates in a small pocket inside the ligament.
• Triggers: Repeated stress, injury, inflammation, or degeneration of the ligament can lead to cyst formation.
• Effects: The cyst can press on nearby nerves and tissues, leading to pain, reduced range of motion, and other joint problems.

Types of Interfoveolar Ligament Cysts

There is no one-size-fits-all classification, but the cysts can be categorized based on certain characteristics:

• Simple Cysts: Fluid-filled sacs with thin walls, generally benign and asymptomatic until they grow.
• Complex Cysts: May have internal septations or debris, potentially causing more symptoms.
• Degenerative Cysts: Often associated with joint wear and tear, found in older patients.
• Traumatic Cysts: Resulting from injury or repeated strain on the ligament.
• Inflammatory Cysts: Related to underlying inflammatory conditions such as arthritis.
