G57: Mononeuropathies of lower limb
G57.3: Lesion of lateral popliteal nerve
The lateral popliteal nerve usually runs from the hollow of the knee along the outside of the lower leg. In the lower leg, the lateral popliteal gives off several branches. These branch nerves run to the foot.
The lateral popliteal nerve controls various muscles in the lower leg. It enables us to raise our foot and stretch our toes, for example. The lateral popliteal nerve is also responsible for sensation on the outside of the lower leg and outside of the foot. This nerve is also responsible for sensation in the arch of the foot.
When the lateral popliteal nerve is damaged, it can cause pain, tingling or a numbness in the lower leg or in the foot, for example. It may also no longer be possible to raise one’s foot so well. One may then trip on the affected foot when walking.
The lateral popliteal nerve may be damaged as a result of pressure, for example. The damage may be lasting or temporary.
