General

Femoral neuropathy, or Lesion of Femoral Nerve, occurs when you can’t move or feel part of your leg because of damaged nerves, specifically the femoral nerve. This can result from an injury, prolonged pressure on the nerve, or damage from disease. In most cases, this condition will go away without treatment. However, medications and physical therapy may be necessary if symptoms don’t improve.

Signs & symptoms

This nerve condition can lead to difficulties moving around. Your leg or knee might feel weak, and you may be unable to put pressure on the affected leg. You might also feel unusual sensations in your legs. They include: * numbness in any part of the leg (typically the front and inside of the thigh, but potentially all the way down to the feet) * tingling in any part of the leg * dull aching pain in the genital region * lower extremity muscle weakness * difficulty extending the knee due to quadriceps weakness * feeling like your leg or knee is going to give out (buckle) on you

Diagnosis

To diagnose femoral neuropathy and its cause, your doctor will perform a comprehensive physical exam and ask questions about recent injuries or surgeries, as well as questions about your medical history. To look for weakness, they will test specific muscles that receive sensation from the femoral nerve. Your doctor will probably check your knee reflexes and ask about changes in feeling in the front part of the thigh and the middle part of the leg. The goal of the evaluation is to determine whether the weakness involves only the femoral nerve or if other nerves also contribute. Additional testing might include: * Nerve conduction * Electromyography (EMG) * MRI and CT scans

Treatment

The first step in treating femoral neuropathy is dealing with the underlying condition or cause. If compression on the nerve is the cause, the goal will be to relieve the compression. Occasionally in mild injuries, such as mild compression or a stretch injury, the problem may resolve spontaneously. For people with diabetes, bringing blood sugar levels back to normal may alleviate nerve dysfunction. If your nerve doesn’t improve on its own, you’ll need treatment. This usually involves medications and physical therapy.
