Groin Pain: Consider Iliopsoas Tendinitis

At the Centeno-Schultz Clinic we acknowledge the pain and restriction in motion associated with groin pain.

Inflammation of the iliopsoas tendon can be a cause of groin and anterior hip pain.  Treatment options include prolotherapy and platelet rich plasma injections.

The psoas and iliacus muscle originate from the lumbar spine, converges to form the iliopsoas muscle and its tendon  attaches onto the lesser trochanter of the femur.

The musculotendinous junction can be found in a groove between the anterior inferior iliac spine and the iliopenctineal eminence.

Major causes of iliopsoas tendinitis are  trauma and overuse resulting from repetitive hip flexion.

In adolescents the combination of inflexible hip flexors and tightness of the iliopsoas muscle and tendon can lead to anterior pelvic tilt and increased stress on the lower lumbar discs and facets.

Groin or anterior thigh pain is a common presentation as illustrated below in red.

Physical examination may be significant for anterior pelvic tilt, tenderness of the iliopsoas tendon and a snapping hip sign.

At the Centeno-Schultz Clinic  a diagnostic ultrasound is utilized to confirm the diagnosis.  Below is an ultrasound image identifying the iliopsoas tendon and adjacent femoral artery.
