The psoas major is one of the key muscles in your body, running from the lower back through the pelvis to the upper thigh. It plays an essential role in hip flexion and stabilizing the spine. Diseases affecting this muscle can cause pain, mobility issues, and other complications.
Psoas major muscle diseases refer to any conditions that affect the psoas major muscle. These conditions can include inflammation, infection, injury, degeneration, or other disorders that impair the muscle’s function.
- Psoas Abscess: An infection leading to a collection of pus in the muscle.
- Psoas Tendinopathy: Inflammation or irritation of the tendon connecting the muscle to the bone.
- Psoas Bursitis: Inflammation of the bursa (a fluid-filled sac) near the psoas tendon.
- Psoas Syndrome: A condition where the muscle becomes tight or spasms, causing pain in the lower back and hip.
- Muscle Strain or Tear: Injury due to overstretching or overuse of the psoas muscle.
These conditions can affect your daily activities, making it difficult to stand, walk, or perform routine tasks.
Pathophysiology: Structure, Blood Supply, Nerve Supply, and Functions
Anatomy and Structure
- Location:
The psoas major originates from the sides of the lumbar vertebrae (L1 to L5) and extends down to attach to the lesser trochanter of the femur (thigh bone). - Layers:
It lies deep within the abdomen, working closely with other core muscles.
Blood Supply
- Key Vessels:
The psoas major receives blood from branches of the lumbar arteries and sometimes the iliolumbar artery. A good blood supply is crucial for muscle repair and function.
Nerve Supply
- Innervation:
The muscle is mainly supplied by the lumbar plexus, including branches such as the femoral nerve and direct branches from the lumbar nerves. This network helps control muscle movement and transmits pain signals if the muscle is injured or inflamed.
Functions of the Psoas Major
- Hip Flexion:
It is the primary muscle used when lifting your knee toward your chest. - Spinal Stability:
It helps maintain the natural curve of your spine and supports overall posture. - Posture and Movement:
The psoas works with other muscles to stabilize the pelvis and lower back, which is essential for walking, running, and bending.
How Diseases Affect the Psoas Major
- Inflammation and Infection:
Conditions like abscesses or bursitis cause swelling and pain. - Strain or Overuse:
Repeated stress can lead to muscle spasms, tendinopathy, or even tears. - Degeneration:
Over time or due to chronic injury, the muscle fibers can degenerate, reducing strength and function. - Nerve Involvement:
Irritation of the nerves that supply the psoas can lead to radiating pain and numbness in the hip or leg.
Types of Psoas Major Muscle Diseases
While the diseases affecting the psoas major muscle may be grouped by their cause or nature, here are some of the common types:
- Psoas Abscess:
An infection within the muscle that can form a pocket of pus. - Psoas Tendinopathy:
Overuse or injury that causes irritation or inflammation of the tendon. - Psoas Bursitis:
Inflammation of the bursa surrounding the psoas tendon. - Psoas Muscle Strain:
A tear or overextension of muscle fibers due to excessive physical activity. - Psoas Syndrome:
Chronic tightness and spasm of the muscle, often causing referred pain. - Myositis:
Inflammation of the muscle tissue, which may be due to autoimmune or infectious causes. - Degenerative Changes:
Wear and tear or age-related degeneration affecting muscle function. - Traumatic Injuries:
Injuries from accidents or falls that damage the muscle. - Tumors:
Rarely, benign or malignant tumors may develop in or near the muscle. - Referred Pain Conditions:
Conditions from nearby structures (such as lumbar spine issues) that affect the psoas muscle function.
Causes of Psoas Major Muscle Diseases
The development of diseases in the psoas major can result from a variety of factors. Here are 20 potential causes:
- Overuse: Repetitive movements, especially in sports or heavy manual work.
