Symptoms

  • Decreased sensation, numbness, or tingling in the top of the foot or the outer part of the upper or lower leg.

Physical therapy and gait retraining can help the person improve their mobility. Some injuries may require peripheral nerve surgery, including one or more of these procedures: Decompression surgery.

Is peroneal nerve same as fibular nerve?

The common peroneal nerve (also referred to as the common fibular nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint.

When the nerve is injured and results in dysfunction, symptoms may include:

  • Decreased sensation, numbness, or tingling in the top of the foot or the outer part of the upper or lower leg.
  • Foot that drops (unable to hold the foot up)
  • Slapping gait (walking pattern in which each step makes a slapping noise)

How do you test the superficial fibular nerve?

To test for the motor involvement of the superficial peroneal nerve and deep peroneal nerve, one must assess foot eversion (SPN) and foot/toe dorsiflexion (DPN). A finding of weakness of both foot eversion as well as foot/toe dorsiflexion suggests a lesion involving the common peroneal nerve.

How do you stretch the peroneal nerve?

This stretch can be performed by sitting on the ground with your feet straight out in front of you:

  1. Wrap a towel around your toes and gently pull back until you feel a stretch at the bottom of the foot and back of the lower leg.

What causes superficial peroneal neuropathy?

Peroneal neuropathies are classically associated with external compression at the level of the fibular head. The most common etiology is habitual leg crossing (which compresses this area). Prolonged positioning with pressure at this area (e.g. sitting on an airplane or positioning during surgery) are other causes.

Where is the fibular nerve located?

The common fibular nerve runs obliquely downward along the lateral border of the popliteal fossa (medial to biceps femoris) before branching, at the neck of the fibula, into the deep fibular and superficial fibular nerve. It lies between the tendon of the biceps femoris and the lateral head of the gastrocnemius.
