Let's talk about the femoral triangle.
It might sound like a fancy dance move, but it's actually a crucial area in our bodies that we need to understand in order to properly treat our patients. So, let's dive into the anatomy, borders, nerves, veins, and femoral sheath of the femoral triangle.
Anatomy of the Femoral Triangle
The femoral triangle is a triangular-shaped depression located in the upper thigh region. It is bordered by three muscles: the adductor longus, the sartorius, and the inguinal ligament. The base of the triangle is located inferiorly and is formed by the superior border of the patella. The apex of the triangle is located superiorly and is formed by the meeting of the adductor longus and sartorius muscles.
Borders of the Femoral Triangle
The superior border of the femoral triangle is formed by the inguinal ligament, which runs from the anterior superior iliac spine to the pubic tubercle. The medial border is formed by the adductor longus muscle, while the lateral border is formed by the sartorius muscle.
Nerves of the Femoral Triangle
The femoral triangle is a significant area for nerve distribution. The femoral nerve is the major nerve that runs through the femoral triangle. This nerve supplies the muscles of the anterior thigh, including the quadriceps and sartorius muscles. It also provides sensory innervation to the anterior thigh, medial leg, and foot.
Veins of the Femoral Triangle
The femoral vein runs through the femoral triangle and is the major vein that drains the lower limb. It runs alongside the femoral artery, which is the major blood vessel that supplies the lower limb with oxygenated blood. The femoral vein is an important site for venous access during medical procedures and surgeries.
Femoral Sheath
The femoral sheath is a structure that runs through the femoral triangle and contains the femoral artery, femoral vein, and femoral canal. It is a potential site for the development of femoral hernias, which can cause significant pain and discomfort for patients.
Clinical Significance for Physiotherapists
As physiotherapists, understanding the femoral triangle is important for several reasons. First, the femoral nerve runs through the femoral triangle and is responsible for innervating several important muscles in the lower limb. Injuries or damage to this nerve can result in weakness or loss of function in these muscles, leading to difficulty with walking and other activities of daily living.
Second, the femoral vein and femoral artery are major blood vessels that supply and drain the lower limb. Understanding the anatomy of these structures is important for identifying potential sites for blood clots, which can be life-threatening if not treated promptly.
Finally, the femoral sheath is an important structure to consider when evaluating patients for potential hernias. Understanding the anatomy of the femoral triangle and the femoral sheath can help physiotherapists identify potential hernias and refer patients for further evaluation and treatment.
The femoral triangle is a significant area in the body that physiotherapists need to understand in order to properly evaluate and treat their patients. By understanding the anatomy, borders, nerves, veins, and femoral sheath of the femoral triangle, physiotherapists can provide comprehensive care for patients with lower limb injuries or conditions.

You're in world-class company:
Over 5 000 clinicians from 40 countries trust us
to bring them the latest studies in clinical injury assessment and rehabilitation.
"These updates help me keep up to date on physiotherapy
evidence-based interventions without needing to search for it in databases.
It really does save time, effort and energy.
My favourite thing is that it is very convenient to learn and read with breakdowns of the information into attractive bite size pieces, making it easy for the reader to digest."
- Candace Goh
"The clinical updates have been a great way to stay up-to-date
on some of the research I may have missed, and also have out some of the grunt work taken out of looking for the research myself while still staying on top of the evidence.
My favorite part of the weekly updates is how easy they are to read!"
- Samantha Greig
"These updates save me a lot of time
and I inform my patients of the updates and what the latest research tells us.
The summary of the articles give me
the most important data in a short but potent way.
Saving me time."
- Denise Gous
"The updates help a lot
in that I'm able to recap on the literature we learned in varsity and it goes more in depth which always helps and it gets me in the groove to read more articles.
My favourite thing about the weekly research updates is how recent the articles are and the humour in the email."
- Bheki Motau
"As a full-time clinician,
there are times when you encounter a rush of patients which reduces the amount of time and effort you may provide to reading research.
This is where these research updates become most useful.
Short and crisp with highlighted findings make the job easier and more effective."
- Payal Adwani
"Just a quick thank you for these emails. Trying to treat patients, get admin done and stay on top of research is such a challenge.
But these emails make things just a little easier!!"
- Meg Steyn
"The updates have helped stay up to date with research
and there is the added bonus that I am don’t have to sift through all the other articles to find it.
My favourite thing is that
the research is clinically relevant
and easy to understand (even the small bits of information before being given the full article.)"
- Keegan Willemse
"Getting synopses of research weekly enables me to
quickly learn about things that are relevant in the setting where I work
without spending hours researching and analyzing
papers for quality of research to see if something might apply where I work."
- Alyson Hackett
"I have found these updates helpful.
I find the content has a nice variability and covers conditions often seen in an out patient private practice
and therefore very relevant."
- Candace Goh
"Your weekly research update is facilitating me to
change my practices
despite of conventional practice.
I also discuss them with my colleagues in my workplace."
- Rasiah Rakunaraj
"Reading the research and getting better ideas of how we can get the best results for our patients is always welcomed.
Nice summarised version which is relatively quick to look through.
Your twist on presenting the research is always fun.
Not too much information all at once and hence the information is digestible and can be worked on. "
- Dr Ron van As
"I am glad to say your updates helped me a lot.
Our profession is changing at a very fast pace, sometimes I struggle as a full time clinician to find time to look for new information, sometimes I find the amount of info is overwhelming and confusing.
Your updates save me time and energy, they're very short and on point.
Thank you so much for your effort, I really appreciate it."
- Dr. Eiman Alkhezi
"The Updates have helped me
to be acquainted with information that
guides my practice as a clinician.
My favourite thing about the weekly Research Updates is that it is usually succinct."
- Akinwande Oluwadamilare
"Ensuring I get a summary of the latest papers and then
I can go deeper
into them if I find them relevant for me."
- Bryce Jackson
"I find these updates so helpful.
It is often so difficult to find time to read articles when you have your own practice.
Between seeing patients and running your practice it becomes difficult to make sure that you are up to date on the latest rehab techniques and new studies that's been done.
I used to spend hours
trying to find relevant articles that actually helps me to treat my patients better.
These updates makes it so easy and the best part is
you can apply what you read in your practice.
I really feel that it makes a huge difference in my practice and if i need to read the whole article it is right at my finger tips.
My favorite thing about these weekly updates is that
I learn something new every week
and then I apply that to my rehab.
I love the fact that I can tell a patient I read this article about their injury and this is the latest an greatest new research about it.
They love it as well.
It is like breath of fresh air in my practice."
