What spinal nerve controls the stomach? vagus nerve.
When the femoral nerve is damaged, it affects your ability to walk and may cause problems with sensation in your leg and foot.
Your sciatic nerve is a long, important nerve that starts just outside of your spine and then travels through your pelvis, into your butt and then to the back of each thigh in each leg. It’s a mixed nerve, which means it has both motor (movement) and sensory (sensation) fibers.
The femoral nerve is located in the pelvis and goes down the front of the leg. It helps the muscles move the hip and straighten the leg. It provides feeling (sensation) to the front of the thigh and part of the lower leg.
Femoral nerve is the main nerve of anterior compartment of thigh. It originates from the dorsal sections of the anterior primary rami of L2, L3, L4 nerves and is the largest branch of lumbar plexus.
- Take a detailed medical history.
- Give you a physical examination.
- Order electromyography to see how well your affected nerves and muscles function.
- Perform nerve conduction tests to test function in specific nerves.
- Order an MRI to check for injuries or tumors.
The femoral nerve is the largest nerve of the lumbar plexus. It forms from the dorsal divisions of the L2-L4 ventral rami.  It has a role in motor and sensory processing in the lower limbs. As a result, it controls the major hip flexor muscles, as well as knee extension muscles.
Cauda is Latin for tail, and equina is Latin for horse (ie, the “horse’s tail”). The CE provides sensory innervation to the saddle area, motor innervation to the sphincters, and parasympathetic innervation to the bladder and lower bowel (ie, from the left splenic flexure to the rectum).
The obturator nerve (L2–L4) supplies the pectineus; adductor (longus, brevis, and magnus); gracilis; and external obturator muscles. This nerve controls adduction and rotation of the thigh.
A pinched nerve in the cervical spine can give you a stiff neck, and the pain and numbness can affect the shoulder and arm. A pinched lumbar nerve in the lower back can cause pain in your back, hips, buttocks and legs.
Sensation changes in the thigh, knee, or leg, such as decreased sensation, numbness, tingling, burning, or pain. Weakness of the knee or leg, including difficulty going up and down stairs — especially down, with a feeling of the knee giving way or buckling.
Common Sciatica Symptoms Usually, sciatica affects only one leg at a time and the symptoms radiate from the lower back or buttock to the thigh and down the leg. Sciatica may cause pain in the front, back, and/or sides of the thigh and leg.
The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
As the disc bulges or prolapses backwards, it can hit the branch of the femoral nerve, causing symptoms into the front of the thigh. Degenerative change around the spine can also narrow the gap (foramen) where the nerve exits the spinal cord, and can pinch the femoral nerve.
Symptoms of a femoral neuropathy may include pain in the inguinal region that is partially relieved by flexion and external rotation of the hip, as well as dysesthesia over the anterior thigh and anteromedial leg. Patients complain of difficulty in walking and of knee buckling, depending on the severity of the injury.
The femoral nerve is a mixed nerve of the lower limb that innervates the muscles and skin of the hip and thigh. The femoral nerve originates from the lumbar plexus, arising from the anterior rami of spinal nerves L2-L4. In fact, it is the longest branch of the lumbar plexus.
Cauda equina syndrome is a rare disorder that usually is a surgical emergency. In patients with cauda equina syndrome, something compresses on the spinal nerve roots. You may need fast treatment to prevent lasting damage leading to incontinence and possibly permanent paralysis of the legs.
The corda equina carries nerves which control the bladder and bowel. The cauda equina also carries nerves which control movement of the legs, and nerves which sense light touch and pain in the legs or around the back passage (perineum).
Conus medullaris syndrome is a type of incomplete spinal cord injury that is less likely to cause paralysis than many other types of spinal cord injuries. Instead, the most common symptoms include: Severe back pain. Strange or jarring sensations in the back, such as buzzing, tingling, or numbness.
MRI scans which show soft tissues, such as nerves and discs, are generally preferred over CT scans which show bony elements. Advanced imaging can show exactly which nerve or nerves are being pinched and what is causing the nerve to be pinched.
Low back pain to one side that travels down the front of or back of the thigh but does not cross the knee. Usually, pain that travels down the thigh is due to a pinched nerve. Nerves can be pinched by either a bulging or herniated disc, an arthritic facet joint, or an overgrowth of bony material, such as a bone spur.
Leg pain coming from the low back, or the lumbar spine, is commonly referred to as sciatica. Sciatica could involve pain in the buttocks, down the thigh, into the leg or in the foot. It is often associated with numbness or tingling, and sometimes weakness.
The lateral femoral cutaneous nerve, which runs through the pelvis, groin and into the thighs, can become compressed due to swelling, trauma or pressure in the surrounding areas. Common causes of meralgia paresthetica may include: Repetitive motion of the legs. Recent injuries to the hip.
- Medication. A doctor may prescribe corticosteroids to reduce inflammation and swelling. …
- Surgery. If a growth or tumor is blocking the femoral nerve, a doctor might recommend surgery to remove it. …
- Lifestyle remedies. …
- Physical therapy.
In less severe cases, treatment of femoral nerve entrapment may be purely symptomatic. Quadriceps weakness may be treated with a locking knee brace to prevent instability, and the patient may require an assistive device for walking. Good recovery is achieved in as many as 70% of patients and may take as long as 1 year.
Chiropractic is a common technique used for femoral neuropathy as it incorporates, adjustments, interferential stimulation, low level laser, massage, thumper, acupuncture and exercises to relieve the tight muscle group.
L3 or L4 impingement from a herniated disc may lead to an abnormal reflex when the area just below the knee is tapped with the rubberized reflex hammer. This is called the patellar reflex. Pain from an L3 or L4 impingement usually radiates to the quadriceps femoris muscle at the front of the thigh.
