What does the lateral femoral cutaneous nerve do?

What does the lateral femoral cutaneous nerve do?

The lateral femoral cutaneous nerve branches off the lumbar plexus, a network of nerves that connects the spinal cord in the lower back with the motor and sensory nerves of the legs and lower body. It provides sensation to the front and sides of the thigh. This is a pure sensory nerve and does not operate any muscles.

How do you treat a lateral femoral cutaneous nerve?

In more severe cases, corticosteroid injections or injectable pain medications may relieve symptoms. Rarely, surgery is necessary to correct any compression on the lateral femoral cutaneous nerve. Surgery is usually only recommended for people who try other treatments but still experience symptoms.

What is lateral femoral nerve?

The lateral femoral cutaneous nerve is a branch of the lumbar plexus, exiting the spinal cord between the L2 and L3 vertebrae. It emerges at the lateral edge of the psoas muscle group, below the ilioinguinal nerve, and then passes beneath the iliac fascia and the inguinal ligament.

What is the motor function of lateral cutaneous nerve of thigh?

Anatomical terms of neuroanatomy 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.

How long does it take for a femoral nerve to heal?

In general, symptoms will get worse for 2 to 4 weeks before they stabilize. Recovery can then take anywhere from a few weeks to a few years, but most people recover in 6 to 12 months.

What is ilioinguinal nerve?

The ilioinguinal nerve, in general, provides sensation to the upper portion of the skin of the inner thigh, and in men, the root of the penis and upper scrotum, and in women, portions of the pubic area. The ilioinguinal nerve block is useful for both evaluating and managing groin pain.

What nerve causes groin pain?

Symptoms of ilioinguinal nerve entrapment may include hyperesthesia or hypoesthesia of the skin along the inguinal ligament. The sensation may radiate to the lower abdomen. Pain may be localized to the medial groin, the labia majora or scrotum, and the inner thigh.

How do you repair femoral nerve damage?

Some treatments of femoral neuropathy include:

1. Medication. A doctor may prescribe corticosteroids to reduce inflammation and swelling.
2. Surgery. If a growth or tumor is blocking the femoral nerve, a doctor might recommend surgery to remove it.
3. Lifestyle remedies.
4. Physical therapy.

Does MRI show meralgia paresthetica?

Imaging studies. Although no specific changes are evident on X-ray if you have meralgia paresthetica, images of your hip and pelvic area might be helpful to exclude other conditions as a cause of your symptoms. If your doctor suspects a tumor could be causing your pain, he or she might order a CT scan or MRI.

Where is the femoris muscle located in the thigh?

Biceps femoris is a long muscle of the posterior aspect of the thigh. Together with the semitendinosus and semimembranosus muscles, it makes the group of muscles commonly known as the hamstrings . Biceps femoris muscle runs from the ischial tuberosity, all the way to the proximal part of the fibula.

Where does the lateral femoral nerve ( LFCN ) originate?

The lateral femoral cutaneous nerve (LFCN) arises from the dorsal divisions of L2-3. After emerging from the lateral border of the psoas major muscle, it courses inferiorly and laterally towards the anterior superior iliac spine (ASIS).

Where is the vastus lateralis muscle located in the femur?

Structure. The vastus lateralis muscle arises from several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.

Which is the largest part of the quadriceps femoris group?

The vastus lateralis is the largest component of the quadriceps femoris group, forming the bulk of the lateral thigh. It originates from the upper part of the intertrochanteric line, the anterior and inferior borders of the greater trochanter, the lateral lip of the gluteal tuberosity, and the proximal half of the lateral lip of the linea aspera.
