summary

Our family is moving these days. There are a lot of things, and I didn't call the moving company. It's all on my own. As a result, I accidentally fell a lot. At that time, the pain in my buttock was so bad that I couldn't stand up. The doctor told me it was a femoral nerve injury. Now let's talk about the femoral nerve injury.

How can nerve of femur injure

First, the femoral nerve originates from the lumbar plexus and is composed of the posterior thigh of the anterior branches of the 2nd, 3rd and 4th lumbar nerves. It passes through the outer edge of the psoas major muscle and runs downward obliquely on the deep surface of the iliopsoas fascia. It reaches the femoral fascia sheath between the psoas major muscle and the iliopsoas muscle, and sends out the iliopsoas major muscle branches and iliopsoas major muscle branches in the iliac fossa.

Second, 2-3cm after the femoral nerve passes through the groin, it divides into the anterior branch and the posterior branch. The anterior branch is divided into the medial femoral cutaneous nerve and the medial femoral cutaneous nerve, which innervate the anteromedial thigh skin and send out the motor branches to innervate the sartorius and pubic muscle. The posterior branch first divides into the muscular branches to match the quadriceps femoris, and then divides into a cutaneous nerve, namely the saphenous nerve.

Third, the saphenous nerve, accompanied by the femoral artery and vein, enters the adductor canal from the femoral triangle, passes through the fascia from the lower end of the canal, and lies behind the sartorius muscle at the knee, then goes subcutaneously with the great saphenous vein to the medial malleolus.

matters needing attention

There is no effective preventive measures for femoral nerve injury, early detection and early diagnosis is the key to the prevention and treatment of this disease, and we must not exercise too early, we must have enough rest time, we must wait until our injury is completely good before we exercise.
