What is innervated by the saphenous nerve?

The saphenous nerve innervates the skin of the medial aspect of the lower leg, the ankle (the medial malleolus), and a small portion of the arch of the foot, close to the saphenous vein.

How do you treat saphenous nerve entrapment?

Saphenous nerve entrapment in the adductor canal usually is treated conservatively by injecting an anesthetic (with or without a corticosteroid) at the point of maximal tenderness (usually 10 cm proximal to the medial femoral condyle). The injection may have to be repeated periodically.

What does the saphenous nerve control?

The saphenous nerve is a branch of the femoral nerve. It is purely a sensory nerve, that is, it conveys only sensory information and does not control any muscle in the leg. It transmits pain, temperature, and touch sensation from parts of the knee and along the inner aspect of the lower leg and foot.

What causes saphenous nerve pain?

Saphenous neuritis is a painful condition caused by either irritation or compression at the adductor canal or elsewhere along the course of the saphenous nerve. The condition also may be associated with surgical or nonsurgical trauma to the nerve, especially at the medial or anterior aspect of the knee.

Why does my saphenous hurt?

What happens when the saphenous vein is removed?

However, stripping may be associated with an increase in morbidity as the result of pain, hematoma, and saphenous neuritis. LSV stripping may also increase hospital stay, limit suitability for day-case surgery and local anesthesia, and deprive the patient of a conduit for arterial bypass later in life.

How is saphenous nerve diagnosed?

Clinical criteria for the diagnosis of saphenous nerve entrapment neuropathy include pain in the distribution of the saphenous nerve, normal motor function, and tenderness to palpation over the entrapment site. Entrapment site tenderness is a key feature of saphenous nerve neuropathy.

Where does the saphenous nerve begin and end?

The saphenous nerve contains only sensory fibers. The saphenous nerve runs posterior to the sartorius, enters the adductor canal and pierces the anterior wall of the channel. After emerging from the adductor canal, the saphenous nerve curves around the medial condyle of the femur, reaching the medial side of the lower leg.

Is the deep stratum medial to the saphenous opening?

The deep stratum is located medial to the saphenous opening. A femoral hernia is a protrusion of an intra-abdominal organ, such as the stomach or small intestine, through the femoral ring, femoral canal and the saphenous opening.

Where to place the needle in a saphenous nerve block?

Saphenous Nerve Block. Aim to place the needle into the fascial plane between the sartorius and vastus medialis muscles. Use an insulated needle if electrical stimulation of the nerve (motor branch) to the vastus medialis muscle is intended. The OOP approach is also commonly used for saphenous nerve block.

Can a saphenous nerve injury cause motor weakness?

In pure saphenous nerve injury, there should be no motor weakness. A Tinel sign may be elicited along the course of the nerve, and occasionally a neuroma may be palpated. MRI is usually unremarkable unless there is a space-occupying lesion.
