The lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve that innervates the skin on the lateral part of the thigh.

Structure

The lateral cutaneous nerve of the thigh is a nerve of the lumbar plexus. It arises from the dorsal divisions of the second and third lumbar nerves. It emerges from the lateral border of the psoas major at about its middle, and crosses the iliacus muscle obliquely, toward the anterior superior iliac spine (ASIS). It then passes under the inguinal ligament, through the lacuna musculorum and then over the sartorius muscle into the thigh, where it divides into an anterior and a posterior branch.

The anterior branch becomes superficial about 10 cm below the inguinal ligament, and divides into branches which are distributed to the skin of the anterior and lateral parts of the thigh, as far as the knee. The terminal filaments of this nerve frequently communicate with the anterior cutaneous branches of the femoral nerve, and with the infrapatellar branch of the saphenous nerve, forming with them the peripatellar plexus.

The posterior branch pierces the fascia lata, and subdivides into filaments which pass backward across the lateral and posterior surfaces of the thigh, supplying the skin from the level of the greater trochanter to the middle of the thigh.

Entrapment is caused by compression of the nerve near the ASIS and inguinal ligament and is commonly known as Meralgia paraesthetica.

PURPOSE: Peri-acetabular osteotomy, especially curved peri-acetabular osteotomy, is an effective surgical procedure for re-orientating the acetabulum. However, there have been few reports on this procedure in teenagers. The purpose of this study was to investigate the treatment outcomes of curved pe

Plantar area reconstruction represents the most challenging part of the lower limb. The anterolateral thigh (ALT) flap proved to be a versatile flap for this special area. Herein, we present the application of bilateral ALT free flaps for foot salvage after frostbite injury and long-term follow-up.
