"The psoas major and iliacus muscles merge at the level of the hip joint capsule, forming a common/conjoint tendon for iliopsoas muscle and inserting into the lesser trochanter; some iliacus muscles fibres directly attach to the lesser trochanter rather than via the tendon 5. The iliopsoas bursa lies between the posterior aspect of the iliopsoas muscle/tendon and the anterior hip joint."
