The tensor fasciae latae muscle originates from the anterior superior iliac spine and inserts into the fascia lata at mid thigh, specifically into the iliotibial band on the lateral aspect of the thigh. The origin and insertion of the tensor fasciae latae muscle are crucial for understanding its function and role in hip and knee movement. Specifically:
- Origin: Anterior portion of the outer lip of the iliac crest, outer surface of the anterior superior iliac spine (ASIS), and the deep surface of the fascia lata 1
- Insertion: Iliotibial band (ITB) of the fascia lata, which attaches to the lateral condyle of the tibia 1 This muscle plays a crucial role in hip and knee function, assisting in hip abduction, flexion, and internal rotation, and helping to stabilize the pelvis during walking and running by tensing the iliotibial band 2. Understanding the muscle's attachments is important for diagnosing and treating conditions like iliotibial band syndrome or hip pain, and proper stretching and strengthening exercises targeting this muscle can help maintain hip mobility and stability 3, 4, 5. The most recent and highest quality study 2 provides detailed information on the development and anatomy of the tensor fasciae latae muscle, highlighting its importance in lateral stabilization of the hip joint. In clinical practice, accurate knowledge of the tensor fasciae latae muscle's origin and insertion is essential for effective diagnosis and treatment of related conditions, and for maintaining optimal hip and knee function 1, 2, 3, 4, 5.
