Puborectalis Muscle Contusion

A Puborectalis muscle contusion is a bruise or injury to one of the key muscles in the pelvic floor. In this guide, we cover what it is, its anatomy, how injuries occur, the causes, symptoms, tests used to diagnose it, various treatment options, medications, surgical procedures if needed, ways to prevent injury, when you should see a doctor, and answers to frequently asked questions.

The puborectalis muscle is part of the pelvic floor muscle group that supports pelvic organs and plays a crucial role in maintaining bowel continence. A contusion in this muscle can lead to pain, discomfort, and impaired function. While injuries to this muscle may not be as commonly discussed as other muscle injuries, understanding its structure, function, and how to treat and prevent injuries is important for anyone dealing with pelvic pain or trauma.

A puborectalis muscle contusion is essentially a bruise of the puborectalis muscle. It occurs when a force or impact damages the tiny blood vessels within the muscle, leading to internal bleeding and inflammation. This can result from trauma or injury that directly affects the pelvic area.

In simple terms, think of it as a “bruise” to a muscle that supports your pelvic organs. This injury may cause pain during movement, difficulties with bowel control, and discomfort when sitting or exercising.

Anatomy and Pathophysiology of the Puborectalis Muscle

Understanding the anatomy of the puborectalis muscle helps explain how a contusion happens and what effects it can have.

Structure

• Location: The puborectalis muscle is part of the levator ani group, found in the pelvic floor. It forms a U-shaped sling around the rectum.
• Role: It is crucial in maintaining the angle between the rectum and the anal canal, which is important for controlling bowel movements.
• Appearance: This muscle, along with its neighboring muscles, is thin and delicate compared to the large muscles of the limbs, yet it plays a major role in pelvic support.

Blood Supply

• Main Vessels: The blood supply comes mainly from branches of the internal pudendal artery, along with contributions from other pelvic vessels.
• Importance: Good blood flow is essential for delivering nutrients and oxygen that help the muscle repair itself after injury.

Nerve Supply

• Nervous Control: The puborectalis muscle receives nerve signals from the pudendal nerve and other nerves within the pelvic plexus.
• Function: This nerve supply controls the muscle’s contraction and relaxation, which is key for both maintaining continence and responding to injury pain.

Functions

1. Maintaining Continence: The muscle helps form the anorectal angle, a key factor in controlling the passage of stool.
2. Pelvic Organ Support: It supports the bladder, uterus (in women), and rectum, contributing to overall pelvic stability.
3. Assisting in Defecation: During bowel movements, the muscle relaxes to allow the passage of stool, then contracts to help close the anal canal afterward.
4. Stabilization: It works with other pelvic muscles to maintain posture and support during activities like lifting or strenuous exercise.

Pathophysiology of a Puborectalis Muscle Contusion

A contusion in the puborectalis muscle results from blunt trauma or impact to the pelvic region. Here’s what happens step by step:

1. Trauma Occurs: A sudden impact (from a fall, sports injury, or accident) hits the pelvic region.
2. Blood Vessel Damage: Tiny blood vessels within the puborectalis muscle tear, causing blood to leak into the muscle tissue.
3. Bleeding and Inflammation: The leaked blood leads to swelling and inflammation. This internal bleeding is what we commonly refer to as a bruise.
4. Pain and Spasm: As the muscle reacts to the injury, it may spasm or cramp, causing pain.
5. Healing Process: The body works to reabsorb the blood and repair damaged muscle fibers. With proper care, most contusions heal over time, although inadequate rest or repeated stress may delay recovery.

Types of Puborectalis Muscle Contusions

Contusions are typically classified by the extent of injury:

Mild (Grade I)

• Characteristics: Minimal damage to muscle fibers, slight pain, little swelling.
• Recovery: Often resolves quickly with rest and basic self-care.

Moderate (Grade II)

• Characteristics: More significant muscle fiber damage, noticeable swelling and bruising, moderate pain.
• Recovery: May require physical therapy and longer rest periods.

Severe (Grade III)

• Characteristics: Extensive tearing of muscle fibers, severe swelling, intense pain, and possible formation of a hematoma (a pocket of blood).
• Recovery: Often requires specialized medical treatment and, in some cases, surgical intervention.
