An obturator fascia hernia is a rare type of pelvic hernia where a part of an organ, often the intestine, pushes through a weakness in the fascia (a thin layer of tissue) near the obturator canal. Because of its hidden location in the pelvis, it can be hard to diagnose and sometimes leads to serious complications if not treated promptly.
In this guide, we break down the basics of obturator fascia hernias in simple terms. We explain the structure, blood and nerve supply, and function of the affected area. We also list many possible causes, symptoms, tests, treatments (both non-pharmacological and with drugs), surgeries, and ways to prevent it.
An obturator fascia hernia occurs when tissue or a part of an organ (most often the small intestine) protrudes through a weak spot in the obturator fascia—a supportive layer of tissue in the pelvic region. Although this type of hernia is uncommon, it mainly affects older, thin women and sometimes elderly men. Because of its deep location, it might not be visible externally and can mimic other abdominal or pelvic issues.
Key Points:
- Location: Pelvic region near the obturator canal.
- Affected Structure: Mainly involves bowel loops pushing through the fascia.
- Risk Group: More common in older, underweight individuals, particularly women.
Pathophysiology of Obturator Fascia Hernia
Understanding the pathophysiology means looking at the anatomy and how the hernia develops.
1. Structure
- Obturator Canal & Fascia: The obturator canal is a small passageway in the pelvis that allows nerves and blood vessels to travel from the pelvic cavity to the thigh. The obturator fascia is the thin tissue covering this area.
- Weakness in the Fascia: With aging or certain stresses, the fascia can weaken. This weakness creates a spot where internal tissues (like intestines) can push through, forming a hernia.
2. Blood Supply
- Local Vessels: The region is served by small blood vessels that come off branches of the internal iliac arteries. These vessels help provide blood flow to the muscles, fascia, and nearby tissues.
- Importance in Healing: Adequate blood supply is crucial for healing and recovery after any surgical repair of the hernia.
3. Nerve Supply
- Obturator Nerve: This nerve passes through the obturator canal and is responsible for sending signals that control the inner thigh muscles. It also relays sensation from the inner thigh.
- Pain and Sensation: When the hernia presses on the obturator nerve, it may cause unusual pain or numbness along the inner thigh—a sign known as the Howship-Romberg sign.
4. Functions of the Area
- Movement: The muscles around the obturator canal help in moving and stabilizing the leg, especially during walking.
- Support: The fascia supports the muscles and internal organs by keeping them in place.
- Protection: Blood vessels and nerves in this area are protected by the fascia. When a hernia occurs, the displaced tissue can compromise these structures, leading to pain or dysfunction.
Types of Obturator Hernias
While “obturator fascia hernia” typically refers to hernias through the obturator canal, there are variations based on clinical presentation and how the hernia appears:
- Right-Sided vs. Left-Sided Hernia: Hernias can occur on either side, with some studies showing a slight preference for the right side.
- Incarcerated Hernia: This type occurs when the herniated tissue becomes trapped and cannot be pushed back into place.
- Strangulated Hernia: A more severe form, where the blood supply to the trapped tissue is compromised, leading to tissue death if not treated promptly.
- Reducible Hernia: In some cases, the hernia can be gently pushed back into place (often seen during early stages).
Understanding these types is important because treatment decisions depend on the severity and type of the hernia.
Causes of Obturator Fascia Hernia
Several factors can contribute to the development of an obturator fascia hernia. Here are 20 potential causes or risk factors:
- Aging: Natural wear and tear can weaken the fascia over time.
- Significant Weight Loss: Sudden or extreme weight loss can reduce the protective fat layer.
- Multiple Pregnancies: Repeated stretching of the pelvic tissues can lead to weakness.
- Chronic Cough: Constant coughing increases abdominal pressure.
- Heavy Lifting: Regular lifting of heavy objects puts strain on the abdominal wall.
- Constipation: Straining during bowel movements increases intra-abdominal pressure.
- Previous Abdominal Surgery: Scar tissue may contribute to fascial weakness.
- Genetic Predisposition: Some people may be born with weaker connective tissues.
- Malnutrition: Poor nutrition can lead to weaker tissues.
- Trauma or Injury: Blunt trauma to the abdomen or pelvis may weaken the fascia.
- Chronic Illnesses: Conditions that affect connective tissue health.
- Postmenopausal Changes: Hormonal changes can affect tissue strength.
- Smoking: Reduced blood flow from smoking affects tissue repair.
- Increased Intra-Abdominal Pressure: From obesity or other conditions.
- Repetitive Physical Stress: Activities that continuously strain the pelvic area.
- Infections: Some infections can weaken fascia.
- Connective Tissue Disorders: Such as Ehlers-Danlos syndrome.
- Previous Hernia History: A history of other hernias might indicate a general weakness.
- Sedentary Lifestyle: Lack of muscle tone can reduce support.
- Chronic Respiratory Diseases: That lead to constant straining.
