What are Iliopsoas Tendonitis and Iliopsoas Syndrome?
Technically, they are two separate conditions, but it’s not uncommon to hear the term iliopsoas tendonitis or iliopsoas syndrome being used to describe the same thing. Iliopsoas tendonitis refers to inflammation of the iliopsoas muscle and can also affect the bursa located underneath the tendon of the iliopsoas muscle. Whereas iliopsoas syndrome refers to a stretch, tear or complete rupture of the iliopsoas muscle and / or tendon. Anatomy of the Hip Joint The iliopsoas muscle is actually made up of two separate muscles located in the anterior (or front) of the hip area. The Iliacus and the Psoas are responsible for lifting the upper leg to the torso, or flexing the torso towards the thigh (as in a sit-up). Although the two muscles start at different points (the psoas originates from the spine, while the iliacus originates from the hip bone) they both end up at the same point; the upper portion of the thigh bone. It is at this point; the insertion, that most injury and hip pain occurs.
