Tendon of iliopsoas muscle

The tendon of the iliopsoas muscle is the distal tendon of the iliopsoas muscle (formed by the convergence of the psoas major and iliacus muscles). It inserts onto the lesser trochanter of the femur.

Traditionally, it has been considered a single conjoint tendon however, recent anatomical studies have shown that the iliopsoas tendon can consist of multiple tendinous components.[1]

In a study by Philippon et al., it was found that the iliopsoas tendon can present as a single, double, or even triple-banded structure in different individuals, with the psoas major tendon being the most medial and the iliacus tendon(s) located laterally. Additionally, the iliopsoas tendon is closely related to the anterior capsulolabral complex of the hip, which can be implicated in conditions such as labral injuries and snapping hip syndrome.[2]
