A Psoas Major Muscle Hernia is a rare condition where tissues or parts of organs push through a weakness or tear in the fascia surrounding the psoas major muscle. This muscle is one of the core muscles located deep in the lower back and runs through the pelvis to the femur. Because of its deep location, symptoms and signs can be subtle and sometimes mistaken for other lower back or groin issues.
In simple terms, a hernia occurs when an internal structure, like fat or even parts of an organ, escapes through a weakened or torn muscle or fascia. With a psoas major muscle hernia, this escape happens near or through the sheath of the psoas major muscle. Although the hernia might not create a noticeable bulge on the surface of the body, it can still cause pain and other problems.
Key points:
- Definition: A condition where internal tissues push through a defect in the fascia of the psoas major muscle.
- Location: Occurs in the deep lower back region, near the lumbar spine and extending into the groin.
- Impact: May cause pain, discomfort, and functional impairment if not properly treated.
Pathophysiology of Psoas Major Muscle Hernia
Understanding the development and functioning of a psoas major muscle hernia involves looking at the structure, blood supply, nerve supply, and functions of the psoas major muscle.
Anatomy and Structure
- Psoas Major Muscle:
- Originates from the lumbar vertebrae (L1 to L5) and inserts into the lesser trochanter of the femur.
- It is part of the iliopsoas group and lies deep in the back.
- It is surrounded by a fibrous sheath that helps protect and support the muscle.
- Hernia Formation:
- Occurs when the fascia (the connective tissue surrounding the muscle) weakens or tears.
- Increased pressure—due to strain, trauma, or other causes—can force internal tissues through this weak spot.
- Because of its deep location, the hernia may not be visible externally, making diagnosis challenging.
Blood Supply
- The psoas major muscle receives blood from branches of the lumbar arteries and iliolumbar arteries.
- Adequate blood supply is critical for muscle health and healing. A herniated area might suffer from reduced blood flow, increasing the risk of complications.
Nerve Supply
- Nerve Innervation:
- The psoas major is innervated by the lumbar plexus, particularly branches from the L1 to L3 nerve roots.
- These nerves control muscle function and also transmit pain signals.
- Nerve irritation caused by a hernia may lead to pain radiating from the lower back into the groin or upper thigh.
Functions of the Psoas Major
- Movement and Stability:
- Aids in hip flexion—important for walking, running, and bending.
- Works with the iliacus muscle to stabilize the spine and pelvis.
- Postural Support:
- Helps maintain the natural curve of the lower spine.
- Plays a role in overall core stability.
- Flexibility and Balance:
- Contributes to the dynamic movements of the lower body.
- Ensures proper alignment during movement, reducing the risk of falls and injuries.
Types of Psoas Major Muscle Hernia
Although psoas major muscle hernias are not as commonly classified as other abdominal hernias, they can be grouped based on their location and underlying cause:
- Primary (Spontaneous) Hernia:
- Develops due to a congenital or idiopathic weakness in the psoas fascia.
- Secondary (Acquired) Hernia:
- Results from trauma, surgery, or other injuries that weaken the fascia.
- Intermuscular Hernia:
- Occurs when the hernia is located between layers of muscle or within the muscle’s own fascial layers.
- Lumbar Hernia Variants:
- In some cases, a psoas hernia is categorized with lumbar hernias that also involve other muscles in the lower back (e.g., Grynfeltt-Lesshaft or Petit’s hernias).
Each type may present differently and can influence the choice of treatment.
Causes of Psoas Major Muscle Hernia
Multiple factors can lead to the development of a psoas major muscle hernia. Here are 20 potential causes:
- Heavy Lifting: Excessive strain increases pressure on the lower back.
- Chronic Cough: Conditions like bronchitis can lead to repetitive pressure.
- Obesity: Extra weight puts additional stress on the fascia.
- Trauma: Direct injury to the lower back or pelvis.
- Surgical Incisions: Prior surgery in the lumbar region may weaken the fascia.
- Degenerative Changes: Age-related weakening of muscles and connective tissue.

- Muscle Tears: Small, unnoticed tears that accumulate over time.
- Infections: Localized infections may damage muscle tissue.
- Excessive Abdominal Pressure: From activities like straining during bowel movements.
- Pregnancy: Increased pressure on the lower back due to the growing uterus.
- Long-Term Sedentary Lifestyle: Leads to muscle atrophy and weakening.
- Aging: Natural loss of muscle mass and elasticity over time.
