A puborectalis muscle hernia refers to a condition where a portion of the tissue or organ, such as fat or sometimes part of the bowel, pushes through or protrudes near the area of the puborectalis muscle. The puborectalis muscle is a key part of the pelvic floor and plays an important role in maintaining continence and supporting pelvic organs. When a hernia occurs here, it can lead to discomfort, pain, or other pelvic floor dysfunction symptoms.
Understanding this condition is important because the puborectalis muscle is essential for:
- Maintaining Fecal Continence: Helping to control bowel movements.
- Supporting Pelvic Organs: Providing structural support to organs in the lower pelvis.
- Stabilizing the Pelvis: Contributing to the overall stability of the pelvic floor.
A hernia in this area can disrupt these functions and cause significant discomfort or complications if left untreated.
Pathophysiology of Puborectalis Muscle Hernia
Anatomy and Structure of the Puborectalis Muscle
- Location: The puborectalis muscle is located in the pelvic floor. It forms a U-shaped sling around the rectum, pulling it forward to help maintain continence.
- Relationship with Other Muscles: It is a part of the levator ani muscle group, working together with the pubococcygeus and iliococcygeus muscles.
- Role in Pelvic Support: This muscle supports the pelvic organs and helps maintain the angle between the rectum and the anal canal.
Blood Supply
- Primary Sources: The blood supply to the puborectalis muscle comes from branches of the internal iliac arteries. These arteries deliver the oxygen and nutrients needed for muscle function and repair.
- Importance: Good blood flow is essential for muscle health and the healing process after an injury such as a hernia.
Nerve Supply
- Nerve Innervation: The puborectalis muscle is mainly controlled by nerves from the pudendal nerve and branches of the sacral plexus.
- Function: These nerves help manage muscle contraction, sensation, and coordination. They are crucial for maintaining continence and pelvic floor stability.
Functions of the Puborectalis Muscle
- Continence Maintenance: By forming a sling around the rectum, it creates an angle that helps prevent involuntary leakage.
- Support of Pelvic Organs: It plays a role in holding pelvic organs (bladder, uterus, and rectum) in their proper positions.
- Pelvic Stability: Works together with other pelvic muscles to stabilize the pelvis during movement.
- Assisting in Defecation: Helps regulate the passage of stool by controlling the angle of the anorectal junction.
How a Hernia Occurs in This Muscle
A hernia in the region of the puborectalis muscle usually happens when there is a weakness or defect in the pelvic floor. This weakness can be due to:
- Trauma or Injury: Direct blows or repetitive strain.
- Surgical Procedures: Previous pelvic surgeries may weaken the area.
- Chronic Pressure: Long-term straining, obesity, or chronic constipation can put extra pressure on the pelvic floor.
- Aging or Childbirth: Natural weakening of muscles over time or due to childbirth.
The resulting defect allows tissues to push through, forming a hernia.
Types of Puborectalis Muscle Hernia
While puborectalis muscle hernias are not as common as other hernias (like inguinal or umbilical hernias), they can be categorized based on location and severity:
- Primary Puborectalis Hernia
- Develops due to inherent weakness in the pelvic floor muscles without any previous surgical history.
- Secondary or Post-Surgical Hernia
- Occurs as a complication following pelvic surgery or injury.
- Small, Localized Hernia
- Involves only a small portion of tissue protruding through a minor defect.
- Large or Extensive Hernia
- Involves a larger portion of tissue and may affect the function of pelvic organs more significantly.
- Interparietal Hernia
- Occurs between the layers of the pelvic muscles, sometimes making diagnosis more challenging.

Lifestyle changes include adopting a high-fiber diet, staying hydrated, avoiding heavy lifting, and incorporating pelvic floor exercises into your routine.
11. Is the condition common in both men and women?
While pelvic floor issues can affect both genders, the incidence and specific causes may vary. Women, especially after childbirth, might be at a higher risk due to pelvic muscle stretching and injury.
12. Can physical therapy help in recovery?
Yes, physical therapy can be very beneficial by providing tailored exercises, manual therapy, and education on proper body mechanics to strengthen the pelvic floor.
13. What are the risks of leaving a puborectalis muscle hernia untreated?
Untreated hernias can lead to chronic pain, worsening pelvic floor dysfunction, and in rare cases, complications like incarceration or strangulation of the herniated tissue.
14. Are there any support groups or resources available?
Many communities have pelvic floor rehabilitation programs, and online support groups can offer advice and shared experiences. Your doctor can also recommend reputable resources.
15. How long does recovery take after treatment?
Recovery time varies depending on the severity of the hernia and the treatment method. Conservative treatment might take several weeks to months, while surgical recovery depends on the complexity of the procedure and individual healing rates.
Conclusion
A puborectalis muscle hernia is a condition that affects the pelvic floor by allowing tissue to bulge through a weakened area near the puborectalis muscle. This muscle is vital for maintaining continence and supporting pelvic organs. Recognizing the symptoms, understanding the causes, and knowing the diagnostic options are key to managing this condition effectively.
There are several non-pharmacological treatments available—from physical therapy and lifestyle modifications to pelvic floor exercises—along with medications and, in more severe cases, surgical interventions.
