Hip osteoarthritis (OA) is a degenerative joint condition typically developed over the years characterised by a progressive loss of articular cartilage.
The pelvis is composed of several bones including the hip bones (ilium, ischium, pubis), sacrum, and coccyx. These structures are connected forming the “pelvic ring” that has the vital function of providing stability, transmitting the loads from the upper to the lower part of the body (and vice versa), and providing connection to different muscles of the upper and lower extremities.
Groin pain is an umbrella term that is implemented to describe a wide spectrum of conditions affecting the area between the upper thigh and the abdomen. This condition may be caused by several reasons and different classification systems have been implemented in the literature.
The iliopsoas is a complex constituted of three different muscles, the iliacus, the psoas major and the psoas minor. Generally speaking, the psoas originates from the lower part of the spine and the iliac fossa (part of the pelvic girdle) and attaches to the anterior-medial aspect of the femur (lesser trochanter)
