Where does the psoas major muscle insert?

The psoas major muscle inserts at the lesser trochanter of the femur. This small, bony prominence is located at the proximal end of the femur, where the psoas major, along with the iliacus muscle, contributes to the hip flexor group. The psoas major plays a crucial role in flexing the hip joint and stabilizing the spine during movement.

Understanding the function of the psoas major is essential for sports massage professionals, as tightness or dysfunction in this muscle can lead to lower back pain, hip issues, and postural imbalances. When creating treatment plans or assessing clients, recognizing the significance of the lesser trochanter as the insertion point helps in targeting the appropriate muscle groups effectively.
