What It Is

Iliopsoas bursitis is inflammation of the iliopsoas bursa, which lies between the iliopsoas muscle and the front of the hip joint capsule. The bursa helps to reduce friction and rubbing between the soft tissues and the bones at the hip joint (Corvino et al., 2020). It is often mistaken for hip joint arthritis, iliopsoas tendinitis or a hip flexor muscle strain. It can become inflamed from trauma or overuse (Corvino et al., 2020), and muscle imbalance or tightness may play a part.

So what exactly is a bursa? It is a small, jelly-like sac containing a little fluid, which acts as a cushion between bones and soft tissues (AAOS, n.d.). Bursitis is simply an inflamed bursa. With iliopsoas bursitis, the pain is felt in the groin area (AAOS, n.d.).

The condition can be caused by a few distinct factors, such as (Corvino et al., 2020)

  • Sports and activities that involve repeated hip bending, such as soccer, martial arts, jumping hurdles and ballet (overuse)
  • Osteoarthritis or rheumatoid arthritis
  • Infection of the bursa
  • Injury (trauma)

Iliopsoas bursitis is not particularly common, and it can be hard to diagnose from symptoms alone. A scan (usually ultrasound, or sometimes CT or MRI) is often needed to confirm it and to tell it apart from other causes of a lump in the groin, such as a hernia, swollen lymph glands or, rarely, a tumour (Corvino et al., 2020).

Iliopsoas Bursitis Anatomy

The hip flexors are a strong group of muscles at the front of the hip. They include the iliopsoas, a deep muscle at the front of the hip, and the sartorius and rectus femoris, which lie over it along the upper front of the thigh.

The hip flexors lift the thigh towards the body, or bend the body towards the thigh, for example when you sit up from lying down. They also help to control the hip when you walk or run.
