What happens if the superficial fibular nerve is damaged?

Direct Damage to the Superficial Fibular Nerve As the muscles that the superficial fibular nerve innervates are evertors, injury to the nerve may result in a loss of eversion. A loss of sensation over the majority of the dorsum of the foot and the anterolateral aspect of the lower leg could also result.

What is superficial neuropathy?

Superficial peroneal nerve syndrome is an entrapment neuropathy that results from mechanical compression of the nerve at or near the point where the nerve pierces the fascia to travel within the subcutaneous tissue. Surgical decompression of the mechanical entrapment usually provides relief from pain and paresthesia.

How do you treat superficial peroneal nerve damage?

Nonsurgical treatments, including orthotics, braces or foot splints that fit inside the person’s shoe, can bring relief. 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.

What is a superficial peroneal nerve?

The superficial peroneal nerve (superficial fibular nerve) is a mixed nerve that carries sensory information from the anterolateral aspect of the leg and the greater part of the dorsum of the foot (except for the first web space).

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.

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.

How long does it take for peroneal nerve palsy to heal?

The recovery time after a common peroneal nerve decompression at the knee is usually 3-4 months. For the first 6 weeks, we do not want to encourage the knee to form a lot of scar tissue around the area of the decompression, so we have patients on crutches.

How do you test for superficial peroneal nerve?

Where does the superficial fibular nerve originate from?

Superficial Fibular (Peroneal) Nerve. The superficial fibular (or peroneal) nerve arises from the common fibular nerve in the proximal leg and travels distally in the leg through the lateral compartment.

What are the signs and symptoms of fibular neuropathy?

The presence of any compound muscle action potential response on motor nerve conduction studies, recorded from either the tibialis anterior or extensor digitorum brevis, is associated with good long-term outcome.

What are symptoms of neuropathy in the superficial peroneal nerve?

Symptoms of neuropathy (nerve damage) in the superficial peroneal nerve may include: Pain in the calf or foot Decreased sensation, numbness, or tingling in the skin innervated by this nerve or its branches Weakness in the foot and ankle due to loss of function in the muscles innervated by this nerve or its branches

Is the superficial nerve a sciatic or sciatic nerve?

The superficial peroneal nerve, also called the superficial fibular nerve, is a peripheral nerve of the calf. It’s a terminal branch of the common peroneal nerve, which itself is a branch of the sciatic nerve.
