G57: Mononeuropathies of lower limb

G57.2: Lesion of femoral nerve

The femoral nerve runs from the pelvis through an opening in the groin. From there, the nerve runs along the front and inside of the thigh, before giving off various branches.

The femoral nerve controls various muscles in the leg. It is used, for example, to bend the hip joint and stretch the knee. The femoral nerve is also responsible for sensation on the front and inside of the thigh. One branch of the femoral nerve is also responsible for sensation on the inside of the lower leg.

When the femoral nerve is damaged, it can cause pain, tingling or a numbness in the thigh or inside of the lower leg, for example. It may also no longer be possible to bend one’s leg at the hip joint so well. It may also no longer be possible to stretch the knee so well.

The femoral nerve may be damaged as a result of pressure, for example. The damage may be lasting or temporary.
