Tensor fasciae latae muscle
Tensor fasciae latae muscle[edit | edit source]
The tensor fasciae latae (TFL) is a small muscle located in the hip region. It is part of the group of muscles known as the hip abductors, which are responsible for moving the leg away from the midline of the body. In this article, we will explore the anatomy, function, and clinical significance of the tensor fasciae latae muscle.
Anatomy[edit | edit source]
The tensor fasciae latae muscle originates from the anterior iliac crest, which is the upper part of the hip bone. It then extends downward and attaches to the iliotibial tract (IT band), a thick band of connective tissue that runs along the outside of the thigh. The TFL is innervated by the superior gluteal nerve.
Function[edit | edit source]
The main function of the tensor fasciae latae muscle is to abduct the hip joint. This means that it helps to move the leg away from the midline of the body. Additionally, it also assists in medial rotation and flexion of the hip joint.
The TFL works in conjunction with other muscles of the hip, such as the gluteus medius and gluteus minimus, to stabilize the pelvis during walking, running, and other activities. It plays a crucial role in maintaining proper alignment and balance of the body.
Clinical Significance[edit | edit source]
The tensor fasciae latae muscle can be subject to various injuries and conditions. One common condition is iliotibial band syndrome (ITBS), which is characterized by pain and inflammation in the IT band. This can result from overuse or repetitive activities such as running or cycling.
Another condition that can affect the TFL is trigger points. These are localized areas of muscle tightness and tenderness that can cause referred pain. Trigger points in the TFL can lead to hip pain, lower back pain, and even knee pain.
