Rectus abdominis fibrosis is a condition in which the normal muscle tissue of the rectus abdominis—one of the main muscles in your abdominal wall—is replaced by fibrous, scar-like tissue. This change can make the muscle stiff and weak, leading to pain and reduced movement. In this guide, we break down what rectus abdominis fibrosis is, explain the anatomy and function of the rectus abdominis, describe how fibrosis develops, and list possible causes, symptoms, and ways to diagnose and treat this condition.

Rectus abdominis fibrosis refers to the thickening and hardening of the rectus abdominis muscle due to the buildup of fibrous (scar) tissue. Normally, the rectus abdominis is a flexible, strong muscle that helps support the trunk and aids in movements like bending and twisting. When fibrosis occurs, the muscle’s flexibility and strength decrease, which can lead to discomfort, pain, and movement difficulties.

Anatomy and Pathophysiology of the Rectus Abdominis

Understanding the anatomy of the rectus abdominis helps explain how fibrosis can affect it. Here’s what you need to know:

Structure

• Location: The rectus abdominis is a pair of long, vertical muscles running on each side of the midline of the abdomen.
• Appearance: These muscles are often visible as the “six-pack” in fit individuals.
• Tissue Composition: In a healthy state, the muscle is composed of muscle fibers that contract and relax to support movement.

Blood Supply

• Arteries: The muscle receives blood from the superior and inferior epigastric arteries. Good blood flow is essential for muscle health and healing.
• Importance: Reduced blood flow can contribute to tissue damage and may worsen fibrosis.

Nerve Supply

• Nerves: The rectus abdominis is primarily supplied by the lower intercostal nerves (from T7 to T12). These nerves control muscle movement and help relay sensations like pain.
• Function: When nerve signals are disrupted (for example, by fibrosis), the muscle’s function and sensation can be affected.

Functions

• Core Stability: It helps stabilize the trunk and supports the lower back.
• Movement: This muscle is key for flexing the spine (as when doing a crunch) and assists in movements like bending forward.
• Posture: A strong rectus abdominis contributes to good posture by keeping the spine aligned.

How Fibrosis Develops

Fibrosis happens when normal muscle tissue is replaced with excess collagen and scar tissue. This can be triggered by:

• Injury or trauma to the muscle
• Inflammation from infection or autoimmune reactions
• Surgical procedures or radiation therapy in the abdominal area

The buildup of fibrous tissue reduces the muscle’s elasticity, making it stiff and less able to contract normally.

Types of Rectus Abdominis Fibrosis

While rectus abdominis fibrosis is not always divided into strict “types,” it can generally be categorized based on its cause or context:

1. Post-Surgical Fibrosis:
   Develops after abdominal surgery when healing processes lead to excess scar tissue.

2. Traumatic Fibrosis:
   Results from direct injury or blunt trauma to the abdominal area.

3. Radiation-Induced Fibrosis:
   Occurs after radiation therapy, where the treatment damages the muscle tissue.

4. Inflammatory or Autoimmune Fibrosis:
   Happens when chronic inflammation or autoimmune diseases trigger fibrosis in the muscle.

5. Idiopathic Fibrosis:
   In cases where the cause is unknown, the fibrosis appears without a clear reason.
