Iliotibial Tract (ITB) Anatomy: Origin, Insertion & Action

[@DavidMacLeod-j1i]

Wonderful - clear, easy to understand, great artwork. The ITB is such an outlier and this explains it perfectly.

[@lynneshapiro3248]

A wonderful vid, indeed! You show very clearly not only how the ITB works to provide a TON of stability to the hip and knee joints, but the joint movement it allows the other muscles to do!

Thanks so much for making this content! I am currently studying to pass Anatomy and Physiology test and your videos are very helpful. Clear, comprehensive, and easy to understand. Thanks!

Best of luck with the test! Glad my videos have been able to help. Thanks for watching.

Thank you, great vids Maybe use a darker background for the white bones will pop up

[@BodyworksPrime]

Thanks for the tip! Do you mean the background I use when I am filming in person or on the illustrations?

Does the itband rest on the vastus lateralis?

[@BodyworksPrime]

Great observation! It doesn't necessarily rest on it, but rather some of the muscle fibers of the VL connect to the ITB. ITB is not generally considered an origin of the VL muscle though. But it's still worth knowing about, as the VL can indirectly influence the position/tension of the ITB. However, it's important to note that the ITB's primary tension and alignment are also significantly influenced by other muscles, particularly the Tensor Fasciae Latae and the Gluteus Maximus, which have a more substantial and direct connections to the ITB.

@@BodyworksPrime Thank you for responding. I'm still confused though because if the VL attaches at the front of the pelvis and wraps around to come to meet one of the hamstrings, how is it not under the ITB? I'm more concerned with how the position/tension of the ITB affects the VL. Sorry to be so stubborn about this!! 8 )

@@maryannegiangregorio2162 No problems at all! I misunderstood your question, I know what you mean now. Part of the VL is deep to the ITB, but it doesn't necessarily "rest" on it, as there is other tissue between them, such as fascia and fat for example. There are some muscle fibers from the VL connecting to the ITB though as previously mentioned. You may find the below paper interesting, it is open access and has some really nice magnetic resonance imaging of the ITB and VL. It also discusses how the ITB is involved in various movements: onlinelibrary.wiley.com/doi/10.1111/j.1469-7580.2006.00531.x

[@maryannegiangregorio2162]

@@BodyworksPrime Thank you again for responding! I now see the confusion was in my wording. So the ITB does not sit directly on the VL but part of the VL is deep to the ITB. Yeah! I thought I'd read that somewhere long ago but few people mention it and I have this image of the VL squishing out both sides of the ITB!! Thank you for the article. I look forward to reading it. 🙏
